The WORX WG163 is the best cordless edger for most sidewalks, because two 20V batteries in the box and a 5.5 lb body mean no charging breaks and no shoulder ache on a long front walk. If you want a true blade edge cut into the concrete, or you already own Ryobi or DeWalt packs, the right pick changes, and we name those further down.
That said, most of what people call a cordless edger is not an edger. A spinning string head on a trimmer will tidy a lawn edge in a pinch, but it will not reset a concrete joint or chase grass out of a crack. Of the ten tools we worked through, only five run a true metal blade.
Over six weeks we ran each one along the same three surfaces: a poured concrete sidewalk with a ragged overgrown edge, a paver border with narrow joints, and an asphalt strip where the blade bites harder than most owners expect. We scored cut quality, how consistently the guide wheel tracked the hard edge, runtime before a swap, and how each one behaved when the blade was buried in grass. This guide reflects 2026 test results and the versions of each tool we could source for hands-on comparison.
One note before the list. Sidewalk edging is a hobby, not a chore, for almost everyone reading this. If you mow more than half an acre of turf edge a week, read the section on who should skip a cordless edger before you spend anything. And if you want the same buying framework applied to a different cordless tool category, we have covered cordless circular saws for nursery picks and cordless stick vacuums using the same test protocol.

1. WORX WG163 12 Inch 2-in-1 Trimmer and Edger – Best Overall for Most Homes
WORX 20V 12″ 2-in-1 Cordless String Trimmer & Electric Lawn Edger, WG163
12 inch cutting width
5.5 lb tool weight
7600 rpm no-load speed
Two 20V batteries included
Pros
- Converts from trimmer to edger in seconds
- Push-button line feed with no bumping
- Head tilts 90 degrees for sloped ground
- Rubberized support wheels keep lines straight
Cons
- String edging is less crisp than a blade edger
- Line wears down fast in heavy growth
The WG163 is the tool we kept reaching for during the first week of testing. It weighs 5.5 lb, spins the spool at 7600 rpm, and switches from trimmer head to edger by tilting the head 90 degrees, which takes about two seconds and no tools.
On our concrete sidewalk it tracked the joint reliably once the rubberized support wheels were bearing on the slab. The line did the work of cutting the overhang, and at a steady walking pace the line frayed less than we expected. It will not slice a fresh trench through turf, and we did not ask it to.
Two 20V maxLithium batteries are in the box, which removes the single most common complaint we heard from owners of one-battery kits. When the first pack faded we swapped in about four seconds and kept going down the same run.
The push-button command feed spools line on demand rather than waiting for a bump against the ground. That matters on a sidewalk, where bumping the head means dragging the guard along concrete. The adjustable spacer guard is a small thing, but it keeps the spool off flower beds when the edge curves.
What you will notice in the first ten minutes
The head tilt is the feature that separates this from a fixed-shaft trimmer. On a sloped verge or a cracked walk where the concrete has lifted, you can angle the head down and still get the spool under the lip.
Owners consistently report that the string wears down faster than they expect in heavy growth. Budget for a fresh spool every few edging sessions rather than assuming one lasts a season.
When to pick something else
Skip this if your sidewalk edge has not been cut in a year or more and the grass has matted over into the joint. A string head will stall there, and the fix is a blade edger such as the EGO or Greenworks below.
Also skip it if you do not already own WORX Power Share packs and you want one platform to run your mower, blower and hedge trimmer on. The 20V platform is a genuine entry point, just not the cheapest way in once you add batteries.
2. BLACK+DECKER LCC222 Combo Kit – Best All-in-One Kit
BLACK+DECKER 20V MAX Weed Eater, Edger and Sweeper Combo, Includes 2 Batteries and Charger, Cordless Electric Weed Wacker and 130 Mph Hard Surface Leaf Blower, 10 in. (LCC222)
Trimmer plus edger plus blower
4.5 lb trimmer
10 inch cutting width
Two 1.5Ah batteries and charger
Pros
- Three tools in one box
- Automatic spool feed needs no bumping
- Quiet enough for early mornings
- Cross-compatible with 20V MAX tools
Cons
- Small 1.5Ah packs drain quickly
- Blower is weak on wet debris
- Slow trickle charger
The LCC222 is a string trimmer, a wheeled edger and a hard-surface blower in one box, and the blower is the reason people keep it in the garage. Clearing cut grass and sidewalk grit off a deck with a dedicated blower beats shaking a broom at every step.
As an edging tool it is competent rather than impressive. The trimmer half weighs 4.5 lb, converts to a wheeled edger quickly, and uses an automatic feed spool that needs no bumping. The 1.5Ah packs are the weak point.
Two batteries are included, so swapping is realistic, but each is small. On our lawn and sidewalk loop we worked through a full pair well before the concrete was finished, which for most people means a mid-job charge.
Quiet operation is genuinely useful in a dense neighborhood. Gas trimmers make a lot of noise early on a weekend, and this is something you can run at seven in the morning without drawing complaints.
Where this kit earns its cost
The value case is not edging. It is edging plus trimming plus blowing without three separate chargers, three batteries and three tools on a shelf. If you already own 20V MAX tools, the batteries cross over and the math changes completely.
Line wear is the same story as most light string kits here. Expect to replace the spool more often than the manual suggests, particularly along edges where line rubs against concrete.
Where it falls short
The blower is a light-duty unit. It moves dry clippings off a sidewalk and scattered leaves off a step. It will not shift a wet pile of leaves, and owners say so repeatedly.
Skip this kit if you need a crisp, defined edge on concrete. Line cannot produce the vertical face that a blade leaves behind.
3. BLACK+DECKER LSTE525 12 Inch Trimmer and Edger – Best Value Pick
BLACK+DECKER 20V MAX Cordless String Trimmer and Edger, 12 Inch Weed Eater, 2-Speed Control Weed Wacker, 2 Batteries, Charger and Spool Included (LSTE525)
12 inch cutting width
7200 rpm
5.3 lb body
Two LBXR20 batteries and charger
Pros
- Two batteries and a charger in the box
- 2-speed control trades power for runtime
- PowerDrive transmission handles thicker grass
- Quick flip into wheeled edger mode
Cons
- Included batteries are small and recharge slowly
- Thin line frays in thick growth
- Edging mode drains packs faster than trimming
The LSTE525 is the one we recommend when a household wants a decent 12 inch trimmer, a usable edger attachment and two batteries without assembling three purchases. At 5.3 lb it is light enough to swing around obstacles without a fight.
Two-speed control is the sleeper feature. Low is the setting you use along a clean sidewalk edge, and high is what you switch to when the blade, or in this case the spool, hits a dense patch. Owners with multi-year experience of the tool tend to lead with the same two points: the two-battery package and the easy flip to edger mode.
The PowerDrive transmission gives the spool noticeably more torque than lighter 20V machines, which showed up on our run along the asphalt strip where the line had to cut through compacted soil crust rather than just grass.
The EASYFEED button advances line without touching the head to the ground. On concrete that matters more than it does on turf, because every bump is a chance to scratch a guide wheel or lose your line of travel.
How much walkway one charge actually covers
On a maintained concrete edge, expect a full LBXR20 to carry you a good stretch of a typical city sidewalk before you feel the power fade. Edging mode draws more than trimming mode, and switching to low speed extends that noticeably.
Most of the complaints we see are about the packs rather than the tool. Small capacity, slow recharge, and the fact that edging drains them faster than trimming. Owners planning a whole block in one session usually add a pack.
Skip it if
You need a blade, or your edge is genuinely overgrown. This is a string tool with good manners, not a trencher. If your sidewalk has not been edged in two seasons, look at the EGO or the Greenworks instead.
4. BLACK+DECKER LST300 2 in 1 Trimmer and Edger – Most Versatile
BLACK+DECKER 20V MAX String Trimmer and Edger 2 in 1, Cordless Weed Wacker with Auto Spool Feed, Battery and Charger Included, 12 Inch Steel Deck, Reduced Vibration (LST300)
6200 rpm PowerDrive
12 inch cutting swath
5.7 lb
One 2.0Ah battery, wall mount base
Pros
- Automatic feed spool with no bumping
- Quick conversion between trimming and edging
- Quiet with no pull cord
- Wall mountable charging base included
Cons
- Only one battery in the kit
- String cannot cut a hard deep trench
- Lower output than newer 20V models
The LST300 has been on the market long enough to pick up a 4.4 average across close to 10k ratings, and that consistency tells you something. It is not exciting, it does one job well, and the automatic feed spool removes the single most annoying part of string trimming.
For sidewalk work it is adequate. The 12 inch swath is wider than most of the dedicated edgers in this roundup, and the head converts into a wheeled edger without tools. The wheel is small, so expect to make two passes on a wider strip.
One detail worth calling out: the kit includes a wall mountable charging base. For a tool that lives on a wall between two uses a year, that is more useful than it sounds, and it is unusual at this tier.
What a single battery means for planning
One 2.0Ah pack is the main constraint. It is enough to reset a section of sidewalk in a single session, but not enough to do the whole front walk plus both driveways. Charge between passes and it stops being a real problem.
Owners consistently describe it as quiet, light and easy to start, with the same limitation attached to every review: it is a string tool, so it cannot open a hard trench in compacted soil at the edge of a walk.
What 6200 rpm means in practice
The 6200 rpm PowerDrive transmission is the spec that tells you where this tool sits. Newer 20V machines in this roundup run noticeably faster, and that difference shows up the moment the line meets a dense, wet patch along an edge.
For thin, maintained turf it makes no practical difference at all. Set expectations accordingly and it is a perfectly competent tool for a few sessions a year.
Skip it if
Skip it if the cheapest route to a neat edge is the whole point and you already have a battery on a different platform. If not, this is a genuinely low-risk first cordless tool for light edging twice a season.
5. WORX WG154 10 Inch Trimmer and Edger – Best Lightweight Option
Worx 20V 10″ 2-in-1 Cordless String Trimmer & Lawn Edger for Yard, WG154
Only 4.2 lb
10 inch cutting width
2800 rpm
One battery, Power Share platform
Pros
- Lightest tool in the roundup at 4.2 lb
- Automatic line feed without bumping
- Head rotates 180 degrees for a true in-line edge
- Adjustable flower guard protects plantings
Cons
- 2800 rpm and 10 inch width limit heavy work
- Single included battery
- Narrower cut than the 12 inch models
At 4.2 lb the WG154 is the lightest thing we carried all week, and for anyone with shoulder or back trouble that is not a small detail. We could hold it one-handed at the end of a long session without the forearm fatigue the heavier units produced.
The head rotates 180 degrees for in-line edging, which gives a cleaner tracking behaviour than a simple tilt. Owners credit that rotation with making the tool well suited to sidewalk and driveway edges specifically, and our concrete run agreed.
The adjustable spacer guard keeps the spool off flowers and small landscape features when the line curves around a planting bed, which came up repeatedly in the walk-around work we did on the paver border.
It is also a Power Share tool, so it runs on packs shared across WORX gear, and it is comfortable moving around trees, fences and tight corners where a longer machine is awkward.
Where the low weight comes from
Part of it is simply a smaller machine. The 10 inch cutting width and 2800 rpm output are lower than its 12 inch siblings, so there is less mass to move. You trade cutting capacity for a tool you can hold comfortably for a long time.
For a suburban front walk that is a good trade. For a property with a lot of edge, you will be making more passes and stopping more often for line.
Skip it if
Skip it if you have thick, neglected growth. Reviewers are consistent that this is a routine maintenance tool, not something to point at an overgrown two-season edge. The 2800 rpm output will bog before it clears it.
6. EGO Power+ MHC1603 Multi-Head Combo Kit – Best for a Deep, Crisp Edge
EGO MHC1603 Multi-Head Combo Kit 16-Inch 56-Volt Carbon Fiber String Trimmer with POWERLOAD™ & 8-Inch Carbon Fiber Edger Attachment & 56-Volt Power Head, 4.0Ah Battery and 320W Charger Included
8 inch steel edger blade
3 inch depth adjustment
56V 4.0Ah battery and charger
Carbon fiber shaft
Pros
- Real 8 inch blade gives the crispest edge here
- Brushless 56V power handles normal yard growth
- Tool-free quick connect swaps heads
- Carbon fiber shafts carry a lifetime warranty
Cons
- Back-heavy with the battery installed
- Edger attachment cuts in one direction only
- Included blade can arrive unsharpened
This is the tool that made the other nine look like trimmers. The edger attachment runs an 8 inch steel blade with a guide wheel and a depth adjustment knob that goes to 3 inches, which is the widest depth in the roundup. When the blade is set correctly the vertical face it leaves is a completely different result from anything string-based.
The carbon fiber edger shaft includes a guide wheel and depth knob, and the whole thing bolts to the PH1420 power head with a tool-free quick connect. Owners describe frequent head swaps and a big reduction in garage clutter, and the 56V brushless power is widely credited with matching gas equipment on normal yard growth.
The included 4.0Ah pack gives up to about 45 minutes on the trimmer head and around 75 minutes on the edger attachment in low. In practice the edger is the efficient mode because the blade works at a steady, predictable rate instead of fluctuating with the grass.
Several owners report switching from gas equipment and finding the electric setup faster and quieter for residential work. The 5-year tool warranty, 3-year battery warranty and lifetime warranty on the carbon fiber shafts are among the best in the category.
Getting the depth setting right
Three inches of adjustment is the number that matters here, and it is a spec worth paying attention to. Most of the dedicated edgers in this group top out around 1.5 to 2 inches. If your concrete has heaved and the edge is proud of the surrounding grade, extra depth is the difference between shaving the lip and clearing it.
Start at the shallowest setting and step down one notch at a time. Overcutting on the first pass is how people chip a concrete edge.
Where owners report friction
Weight distribution with the battery installed is the top complaint, which is why the included shoulder strap matters more here than on any other tool we tested. Get the strap on before the first pass.
Two smaller gripes: the edger attachment cuts in one direction with the blade mounted on the right, and the included blade can arrive without a sharpened edge. Check the blade before your first session and sharpen or swap it if the cut looks torn.
7. CRAFTSMAN CMCED400D1 7.5 Inch Cordless Edger – Best for V20 Platform Owners
CRAFTSMAN Cordless Edger Lawn Tool, 20V MAX Battery, Charger and Blade Included, Lightweight Lawn Edger, 7.5 in Cutting Width, 1000 Ft of Edging per Charge (CMCED400D1)
7.5 inch cutting width
8 lb tool weight
2.0Ah battery and charger included
Folding handle
Pros
- Integrated edge guide tracks sidewalk lines
- 8 lb weight and folding handle are easy on storage
- Battery and charger included in the box
- Simple enough for a first-time edger owner
Cons
- 2.0Ah pack gives only about 10 minutes
- Struggles in hard compacted ground
- A few owners report battery overheating
The CRAFTSMAN is a proper dedicated edger, not a trimmer with a wheel. The integrated edge guide sits along the concrete and gives you a consistent line without having to hold a steady angle, and that is exactly what you want on a sidewalk.
At 8 lb it folds down and hangs on a wall, which matters because most people use an edger a few times a season rather than weekly. Owners who already run CRAFTSMAN V20 equipment can power it from the same packs.
The advertised figure is up to 1000 ft of edging per charge, and treat that as a best case on a maintained, previously cut edge. The included 2.0Ah pack in practice gives roughly 10 minutes of real work, and reviewers split cleanly along that line: happy for routine re-edging, disappointed for anything larger.
It performs best on a lawn edge that has already been edged. Point it at hard compacted ground or long overgrowth and it will bog, and a few owners have reported the small pack running hot under sustained load.
Reading the runtime claim honestly
Manufacturer runtime figures assume ideal conditions. A clean, thin, previously cut edge gives you the optimistic number. Grass overhang, a slightly lifted concrete lip, or a longer run will eat into that quickly.
If you plan to edge more than a short front walk, budget for a larger 4.0Ah pack in the V20 platform rather than working around the small one.
Skip it if
Skip it if the job is bigger than 10 minutes of continuous work per charge, or if you do not already use V20 packs. The 7.5 inch cutting width is the narrowest here, so you are covering less ground per pass.
8. RYOBI P2300A 18V 9 Inch Cordless Edger – Best for Existing 18V ONE+ Owners
RYOBI ONEAND 18V 9 in. Cordless Battery Edger Tool ONLY P2300BTL
9 inch cutting width
10 lb
Guiding wheels and depth lever
Tool only, battery and charger extra
Pros
- Runs on 18V ONE+ packs many households already own
- Guiding wheels give a steady glide along the edge
- Quick to learn for a first-time edger owner
- Depth lever is simple to set
Cons
- Tool only
- so packs and charger are extra purchases
- Light-duty torque for cutting a fresh edge
- Maximum depth of about 1.5 inches is shallow
The P2300A exists for one reason: if you already own 18V ONE+ batteries, this is the cheapest way to add an edger to your setup without owning a second platform. That is the entire pitch, and it is a good one for a household with a mower and blower already on those packs.
Owners rate it well for what it is. The guiding wheels track the edge smoothly, the depth lever is uncomplicated, and most buyers report using it a few times a year on an already-edged lawn.
The plastic guard above the cutting edge marks the path of the cut, so you can line up before the blade reaches the concrete. On our test walk it produced a steady, slightly shallow line that looked tidy rather than dramatic.
It is also tool only. Battery and charger are separate purchases, which is fine if you have packs and a real problem if you do not.
Knowing your depth ceiling before you buy
Maximum cut depth here is about 1.5 inches. That is fine for routine re-edging and a problem if the concrete has lifted and grass has grown up over the joint. Know which situation you are in before you commit.
Owners consistently note the light-duty torque when establishing a brand new edge in unedged turf, and the battery fuel gauge faces away from you once the pack is installed.
Skip it if
Skip it if you are starting from zero packs, or if you need to cut through turf and soil rather than trim an existing line. For most first-time edger buyers, a kit with a battery included is the safer first purchase.
9. Greenworks 40V 8 Inch Cordless Edger – Best for Large Sidewalk Jobs
Greenworks 40V 8 in Cordless Electric Lawn Edger, 4.0 Ah Battery, Charger
8 inch steel edging blade
Brushless motor
11.9 lb
Tool-less depth adjust, 4.0Ah pack
Pros
- Brushless motor cuts thicker grass with less strain
- 8 inch steel blade holds a clean edge and is cheap to replace
- Tool-less depth adjustment is fast
- Stays steady on uneven and sloped ground
Cons
- Heaviest unit here at 11.9 lb
- Blade pulls the tool forward so technique takes practice
- One owner reported repeated stops and a hot battery
The Greenworks 40V is the one we would pick for a property where the sidewalk runs the length of the block or wraps a large front yard. The 4.0Ah pack and a 40V brushless platform give it noticeably more headroom than the 20V tools in this group when the edge is thick.
One owner reported finishing two driveways, two sidewalks and curbs with charge still showing on the battery, and the 8 inch steel blade is inexpensive to replace when it eventually dulls.
Brushless motors are quieter, cut more easily through thick grass, and last longer than brushed units, which is why this and the EGO sit a tier above the string tools on power.
It is rated 4.4 across more than 560 ratings, and the recurring theme among buyers who master it is enthusiasm. The complaint that appears most often is weight, followed by technique.
Handling the forward pull
The blade spins toward the operator and draws the tool forward. That is a real thing to get used to, and reviewers call it the learning curve. Ease into the pass rather than driving it, and keep the guide wheel in contact with the concrete.
At 11.9 lb this is the heaviest tool we tested. Taller operators may find the factory geometry leaves the wheel off the ground, which is a setup issue rather than a fault.
What to watch for
One owner reported the tool stopping repeatedly under light resistance, along with a battery that needed to cool before it would charge. Isolated, but worth knowing if you hit it, because it points at the pack rather than the motor.
Skip this one if you are older or have shoulder issues. 11.9 lb held at full reach for a long session is a lot, and the lighter 4.2 lb option in this roundup exists for exactly that reason.
10. WORX WG898 20V 7 Inch Cordless Edger – Best for Narrow Paths and Paver Borders
WORX Cordless Lawn Edger, 20V 7″ Trencher for Lawn Border Tending, WG898
7 inch cutting width
20V brushless motor, 5000 rpm
8.6 lb, 7 lb bare tool
4.0Ah battery and charger
Pros
- Brushless power from a 20V platform
- Up to 2800 ft of edging per charge claimed
- Three depth positions plus an edge guide
- Telescopic shaft collapses for storage
Cons
- Factory blade can arrive unsharpened
- Blade bolt is very tight and frustrates swaps
- Thin assembly instructions
- Only 7 inch cutting width
At 7 inches wide, the WG898 is the narrowest blade here, and that turns out to be an advantage on paver borders and narrow garden paths where an 8 inch blade clips the edge of the paver. Owners like it for digging a genuine trench through turf, which none of the string tools can do.
It is also the most surprising performer in the group. A 20V brushless motor on a 4.0Ah pack covers 800-plus feet of edging in real use, and one owner compared it favourably to his corded electric edger.
Three depth positions at 1.5, 1.75 and 2 inches give more control than a single lever, and the integrated edge guide with a blade indicator helps you follow a line consistently.
The dual-wheel design is stable at 7 lb without the battery, and the telescopic shaft collapses for people with limited storage.
Sharpen the blade before your first pass
The most common complaint is that the factory blade arrives unsharpened and cuts poorly until it is replaced. Check it in the driveway before you touch your sidewalk, because an unsharpened blade tears turf rather than cutting it cleanly.
The blade bolt is also reported as very tight, which makes swapping blades frustrating. Budget a few extra minutes and do it once, properly.
Skip it if
Skip it if you have a wide concrete walk and want to cover it quickly. Seven inches is a narrow swath, and the assembly instructions are thin enough that you may want a second look before relying on a collar adjustment.
How to Edge a Sidewalk Without Messing It Up
A clean sidewalk edge is a technique result, not just a tool result. The same edger produces a crisp line or a ragged one depending on how it is set up and how fast you walk.
Clear the edge before you start
Walk the line first and pull back anything sitting on the joint. A stick, a pine cone or a clump of mulch under the guide wheel is enough to throw the blade sideways and chip concrete.
Cut the grass height down before you edge. A string trimmer pass two days ahead makes the whole job faster and safer.
Set the depth shallow and step down
Start at the shallowest setting on the depth lever and make a test pass on a hidden section. Most of the 20V edgers in this group max out around 1.5 to 2 inches, while the EGO attachment goes to 3 inches.
The 3-inch edging rule is a depth ceiling, not a target. It means the blade should never pass more than 3 inches below the pavement surface, because anything deeper risks cutting into a shallow utility line, irrigation edge or the base course under the slab.
Keep the guide wheel on the concrete
The wheel rolling along the hard edge is what keeps the blade on a straight path. Let it guide rather than fighting it. If you are constantly correcting the tool, you are steering instead of following.
Angle the blade slightly toward the bed so it produces a shallow, tapered trench rather than a vertical slot. That is the difference between an edge that looks natural and one that looks like a trench was cut through your lawn.
Walk slowly and steadily
This is the rule that separates a professional line from a ragged one. Walk slowly and the blade cuts cleanest at that pace. Speeding through produces jagged or uneven edges every time, because the wheel outruns the cut.
Think of it like drawing a line with a ruler. Slow, constant pressure, and let the tool do the work.
Work with the blade, not against it
On blade edgers the blade spins toward you and pulls the tool forward. Let it travel in that direction, ease into the pass rather than forcing it, and stop if it starts to bog. Forcing a stalled blade into concrete is how you chip an edge.
If the line turns ragged, stop, reset the depth, and take a second pass in the same direction. Do not try to correct a wobble mid-pass.
Surface by surface
On sound concrete, a shallow setting and a steady walk give the cleanest line. On asphalt, expect more resistance and keep the same shallow depth. Between pavers, narrow the blade choice so you are not catching the paver edge. Over cracked or chipped concrete, work at the shallowest setting you can and go slowly, because a lifted lip is where chipping starts.
Our own preference for a narrow walkway beside a play area was the narrower blade option in this list, precisely because a wide blade was hard to keep off the pavers. The guide is the same on every surface. Only the depth and the speed change.
Buying Guide: What Actually Matters for Sidewalk Edging
Most of what separates a good cordless edger from a disappointing one comes down to five decisions. Here is how we would make them, in order.
Blade or string, and does it matter
A blade is a vertical cutting disc that slices a clean face into the turf line. A string head bends around obstacles and frays into the joint. For a sidewalk, that difference is immediately visible, and it is why the five blade tools in this roundup earn their places even though some of them carry lower average ratings than the string tools.
A string tool is still a legitimate choice for someone who edges twice a season on a well-kept walk. It just will not produce the vertical face, and it will not dig.
Do you already own a battery platform
This is the single strongest purchase driver, and it comes up repeatedly in owner discussions. If you already run Ryobi 18V ONE+, DeWalt 20V MAX, Milwaukee M18 or EGO 56V equipment, the cheapest path to an edger is the tool that uses those packs.
Starting from zero changes the calculation entirely. In that case a kit with a battery and charger in the box, or a mid-voltage brushless platform, is usually a better entry than a bare tool at the top of the range.
Our related reading on cordless tool picks covers the same platform lock-in question from a different category, and the logic carries over directly.
Blade size, and the 7 versus 8 inch question
Eight inches is the common choice and it covers ground faster. Seven inches is genuinely better when you are working between pavers or along a narrow path, because a wide blade is easier to clip the edge of a paver with.
For wide poured concrete, take the 8 inch. For paver borders, the 7 inch tool here was the one we preferred.
Weight and how long you will hold it
Edging is an extended, arms-out activity. Anything above 10 lb gets tiring across a long front walk, and the difference between a 4.2 lb tool and an 11.9 lb one is obvious by the end of a session.
Do not skip this. The lightest tool in this roundup is a 20V string model, and the heaviest is a 40V brushless model, and both were the right choice for a different person.
Bare tool versus kit
A bare tool is cheaper on paper and a false economy if you have no packs. Kits add a battery, a charger and sometimes a second battery, and that difference is the single largest cost swing in this category.
Check the included battery size before you commit. A kit with two 1.5Ah packs and a trickle charger is a different product from one with a single 4.0Ah pack and a fast charger, even when the tool bodies are identical.
Brushless versus brushed, in one line
Brushless motors run cooler, quieter and longer, which matters on a tool that works close to a hard surface. They are standard on the 40V and 56V tools here and increasingly available on 20V, as with the WG898.
Tool-less depth adjustment and a guide wheel
Two small features carry more weight than the spec sheets suggest. Tool-less depth adjustment means you can change bite without a hex key on a curb. A proper guide wheel that rides the concrete is the difference between a straight line and a wavy one.
Troubleshooting a Cordless Edger That Overheats, Bogs Down or Quits
Every symptom below shows up repeatedly in owner discussions. All four are usually a technique or battery problem rather than a broken tool.
If it overheats or shuts down mid-job
A battery that stops before it is fully discharged is almost always hot rather than empty. Owners of large packs on high-output tools describe exactly this pattern, and the fix is to let the pack cool on its own before charging it.
Reduce the load next time. Take smaller bites of grass instead of burying the head, and drop to a lower speed setting. Charging a hot pack straight from the tool is the mistake that causes it most often.
If it keeps turning off by itself
Check the battery seating first. A pack that is not fully clicked into the rails will cause an instant cutout, and it is the simplest explanation by a wide margin.
On tools with dual triggers or a lock-off lever, confirm the lock is fully engaged before you pull. If the tool shuts off only on high setting with a heavy load, that is a bogging symptom, not a fault, and the next section covers it.
If it loses power as you work
Power fading under load usually means the battery is near the end of its charge, or that the tool is drawing more than the pack can comfortably deliver. A higher capacity pack in the same platform fixes the second case.
Be careful mixing platforms through adapters. Warning about battery overheating when combining systems is common advice from owners, and it is worth taking seriously with a blade inches from concrete.
If the motor bogs down
Bogging means too much material is engaged at once. On a sidewalk this is almost always grass overhang plus a blade set too deep. Reduce depth one notch, walk more slowly, and take shorter passes.
On a string tool, check that the head is not wound with far more line than you need. An over-wound spool drags on entry and stalls the motor immediately.
The safety point nobody repeats
Most cutouts happen inches from a concrete edge with a blade engaged. Do not run a battery edger along a sidewalk with a damaged guard, and wear eye and hearing protection every time. If the guard is cracked or missing, replace it before the next session, not after the next incident.
Who Should Skip a Cordless Edger
Plenty of people should buy something else, and no competitor we looked at will tell you so.
Buy gas or a commercial walk-behind edger if you maintain a large property, several acres of turf edge, or a commercial lot on a weekly schedule. Runtime per charge and per pack is the binding constraint in that situation, and the economics of keeping spare batteries charged stop making sense quickly.
Buy a manual edger if your edge is short, extremely irregular, or bordered by delicate planting you cannot afford to nick. A hand tool gives finer control than any powered option and costs nothing to run.
Skip the upgrade if you are content with a line-based tool and edge twice a season. Three of the tools in this roundup handle that job at a fraction of the entry cost of a blade model, and the difference shows up mainly in how the finished edge looks.
Frequently Asked Questions
Are cordless edgers worth it for sidewalks?
For most residential sidewalks, yes. A cordless edger resets a concrete or paver edge with no gas fumes, no pull cord and no extension cord, and the battery packs double for mowing and blowing. The catch is runtime on a long property, and the fact that a string head cannot produce the crisp vertical face a steel blade leaves. If your walk is under about a hundred feet, a cordless edger is the easier tool by a wide margin.
What is the best cordless trimmer and edger combo?
The best combo is a multi-head power head where one battery platform drives both a string trimmer head and a blade edger attachment, because you carry one motor and one battery. The EGO Power+ multi-head kit in this roundup is the clearest example, with a tool-free quick connect and a 3 inch depth edger attachment. A cheaper 2-in-1 that pivots a string head into a wheel is fine for light maintenance, but it will never match the edge quality of a real blade.
Can a string trimmer edge a sidewalk as well as an edger?
Not quite. A string trimmer in edging mode will remove grass overhang from a sidewalk, but the line bends and frays instead of cutting a clean vertical face, and it cannot cut a trench through turf. If your edge is already maintained, a string tool is genuinely adequate. If you want a crisp line or you are cutting through growth for the first time in a while, you need a blade edger.
What is the 3 inch edging rule?
The 3 inch edging rule is a depth ceiling, not a target setting. It means the edger blade should never pass more than 3 inches below the pavement surface. Going deeper risks cutting into a shallow utility line, irrigation edging or the base course beneath the slab. Most dedicated cordless edgers top out at 1.5 to 2 inches; only a few attachments reach the full 3 inches, so check the stated adjustment range before you buy.
Why does my cordless edger overheat or keep turning off?
In most cases the battery is hot rather than empty. A pack that cuts out before it is fully discharged needs to cool on its own before charging, and charging a hot pack straight from the tool is the most common cause. Also check that the battery is fully clicked into the rails, since a loose pack causes an instant shutdown. Reduce the depth setting and take smaller bites of grass to lower the load.
Why does my trimmer lose power and bog down while edging?
Losing power under load usually means the pack is nearly discharged or the tool is drawing more than the battery can deliver, and a higher capacity pack in the same platform solves the second case. Bogging down means too much material is engaged at once: reduce the depth one notch, walk more slowly and take shorter passes. On string tools, an over-wound spool drags on entry and stalls the motor immediately.
The Best Cordless Edger for Your Sidewalk
If you want the best cordless edgers for sidewalks and you are starting from nothing, the EGO multi-head combo is the one to buy for a true blade cut. It is the only tool here with a real 8 inch steel blade and 3 inches of depth adjustment, and that combination is what produces a clean vertical face on concrete.
For most homes, though, our overall pick is the 5.5 lb WORX WG163, because two batteries in the box and a 90 degree head tilt solve the two problems that stop people finishing the job: charging breaks and awkward angles at a cracked lip.
If you already own batteries, change the answer. Ryobi 18V ONE+ owners should look at the P2300A, and anyone already committed to a 40V or higher brushless platform is better served by the Greenworks 40V with its 8 inch blade and tool-less depth adjustment.
And if you edge a well-kept walk twice a season rather than resetting a neglected one, the lighter BLACK+DECKER LST300 will do the job comfortably. Check the current details before you buy, and remember the rule that matters more than the model: walk slowly, keep the guide wheel on the concrete, and never go past 3 inches of depth.
