Our top picks

Side by side

Spec comparison

A lawn edger cuts a vertical slot between grass and a walkway or bed, and it does so with either a steel blade or trimmer line turned on its side. The difference between those two methods shapes everything, from how crisp the edge looks to how much sod the tool can cut.

This guide explains blade size, cutting depth, motor type and battery capacity, and why the tool type matters before any spec. Start with the picks above for a shortlist, then read the reviews below to see which fits your yard and your batteries.

Before you buy

6 Criteria to Look For Before Buying a 20V Cordless Lawn Edger

  1. 01

    Blade edger versus line edger

    A steel-blade edger slices a vertical channel and gives the crisp, sharp edge people expect along walks and beds. A string trimmer turned on its side trims line-width and leaves a softer edge. Buyers often assume the two are interchangeable and then feel disappointed with line results. The WORX WG163 is a line edger, while the WG898, goodjob, ECOWORK, Mayoki and VEVOR are blade edgers.

  2. 02

    Blade diameter

    A bigger blade cuts deeper in a single pass because more of its radius sits below the deck, but it also takes more power and weighs more. A 7 inch blade is easy to control, while a 9 inch blade cuts deeper but demands more battery. The WORX WG898 uses 7 inches, VEVOR 8.8 inches and the goodjob, ECOWORK and Mayoki 9 inches.

  3. 03

    Cutting depth settings

    Depth adjustment lets you set a shallow trim for maintenance or a deeper cut for new borders. Maximum depth matters mostly when you establish an edge, since regular trimming only needs a shallow pass. The ECOWORK reaches 1.75 inches, VEVOR 1.5 inches, and goodjob and Mayoki offer three settings.

  4. 04

    Motor type and battery

    Blade edgers pull heavily on the battery because the blade meets soil and roots. A brushless motor and a larger pack extend how long you can edge. A 2.0Ah pair gives modest runtime, whereas a 4.0Ah pack roughly doubles it. The WORX and Mayoki are brushless, and the ECOWORK and VEVOR include roughly 4.0Ah packs.

  5. 05

    Weight and guide wheels

    Guide wheels keep the blade tracking on a line, and weight changes how fatiguing the tool is across a whole edge. A light edger is easy to carry, but a heavier one with wheels often tracks more accurately. The goodjob is about 4.5 pounds with guide wheels, and the WORX WG898 about 7 pounds bare with dual wheels.

  6. 06

    Safety and debris

    Blade edgers throw soil, stones and grass at speed, so eye protection and sturdy shoes are essential. A blade guard and a stable stance reduce the risk. Never edge near people or pets, and clear stones before you start. Remove the battery before cleaning the blade.

Detailed reviews

The 6 best 20v cordless lawn edgers, explained

01
WORX WG898.9 20V 7 Inch Brushless Lawn Edger (Tool Only)
7 in bladeBrushless motor7 lb bareEdge guide
Check price on Amazon
Best for: PowerShare owners who want a controlled, straight edge along walks and beds.

The WG898 is a dedicated blade edger with a streamlined 7 inch blade, brushless motor and a dual-wheel chassis that tracks straight. An edge guide and blade indicator help you place the cut right on the line, which is the part of edging most people struggle with.

At about 7 pounds without the battery, it is heavier than the 4.5 pound goodjob, and the wheels provide balance that a lighter tool lacks. The brushless motor wastes less energy, and WORX rates runtime at up to 2,800 feet per charge, a light-load figure. Its blade is smaller than the 9 inch units here, which means a shallower or slimmer cut, but the control is better.

It is sold without battery or charger, so it works best for people already in the WORX PowerShare ecosystem. Brush the blade clean after each use and check it for chips.

What works

  • Brushless motor stretches the battery on long edges
  • Edge guide and blade indicator help line placement
  • Dual wheels keep the tool balanced and tracking
  • Battery fits a large family of PowerShare tools

Watch out for

  • Sold as a bare tool, so a battery and charger cost extra
  • 7 in blade is smaller than the 9 in competitors
  • About 7 lb is heavier than the lightest edgers here

goodjob 20V 9 Inch Cordless Lawn Edger Kit
9 in blade3,500 RPM4.5 lb2 x 2.0Ah
Check price on Amazon
Best for: Homeowners who want a complete, light blade edger kit without buying batteries separately.

goodjob's kit pairs a 9 inch steel blade with a 400 watt motor at 3,500 RPM, a combination that favors speed over torque. At about 4.5 pounds, it is among the lightest blade edgers, which makes it comfortable for people who tire during long edging sessions.

Three adjustable depths and dual guide wheels give it flexibility on different edges. The two 2.0Ah batteries are modest, about half the capacity of the ECOWORK's single 4.0Ah pack, so expect to edge a modest lawn before charging.

It is the budget kit that includes everything. The brand is lesser known, so check battery availability. Clean the blade after each use.

What works

  • Includes two batteries and a charger in the box
  • About 4.5 lb is light for a blade edger
  • Three depth settings suit varied soil
  • Dual guide wheels help keep lines straight

Watch out for

  • 2.0Ah batteries limit runtime on long edges
  • Lesser-known brand with unproven battery supply

ECOWORK 20V Cordless 9 Inch Lawn Edger and Trencher Kit
9 in blade3,500 RPM4.0Ah battery1.75 in depth
Check price on Amazon
Best for: Yards that need deeper trenching for borders as well as ordinary edging.

ECOWORK's edger doubles as a small trencher, with up to 1.75 inches of cutting depth. That depth is the most among these 20V models and suits trenching for lawn borders and light landscape edging.

A 4.0Ah battery is the largest single pack in the blade edgers here, and four height levels with a three-position parallel guide give fine control. The 9 inch blade and 3,500 RPM motor match the goodjob, but the bigger battery buys longer runs.

Depth is not a licence to cut through hard soil, since a 20V motor will stall in compacted clay. Brush the blade clean after each use and check the guide wheels.

What works

  • Up to 1.75 in depth is the deepest here
  • 4.0Ah battery gives the best runtime among blade kits
  • Four height levels allow fine adjustment
  • Parallel guide helps keep a consistent line

Watch out for

  • Compacted soil will stall a 20V motor at full depth
  • Less established brand for parts and batteries

Mayoki Brushless 9 Inch Lawn Edger for DeWalt 20V (Tool Only)
9 in bladeBrushless 3,200 RPM3 depth settingsTool only
Check price on Amazon
Best for: DeWalt 20V MAX owners who want a brushless blade edger on batteries they own.

The Mayoki is a brushless 9 inch edger that runs on DeWalt 20V MAX batteries, so it makes sense for people who already own those packs. The brushless motor is more efficient than the brushed designs that power several other edgers in this lineup.

A 180 degree adjustable auxiliary handle and a rear guide wheel give you control over your stance and line. Three depth positions cover shallow trims to deeper trenching along driveways. It lacks batteries, so the total cost depends on what you already own.

As a third-party tool on a DeWalt interface, there is no shared warranty. Check the pack seats firmly, and brush the blade after use.

What works

  • Brushless motor is more efficient than brushed rivals
  • Runs on DeWalt 20V MAX batteries you already own
  • 180 degree auxiliary handle improves ergonomics
  • Rear guide wheel keeps a straighter line

Watch out for

  • Tool only, so battery and charger are extra
  • Third-party tool on a DeWalt pack has no shared warranty

VEVOR 20V 8.8 Inch Cordless Lawn Edger
8.8 in blade3,200 RPM3 depths65Mn steel
Check price on Amazon
Best for: Lawns with occasional roots and stones that punish soft blades.

VEVOR's edger uses an 8.8 inch blade of 65Mn high-carbon steel, a spring steel that holds an edge and flexes without cracking. That helps when the blade meets a root or a buried stone.

Three depth settings, at 1, 1.25 and 1.5 inches, cover most lawn edging. The 4,000mAh pack matches the ECOWORK's 4.0Ah capacity, and the steel tube shaft is sturdier than plastic. A pivoting handle gives some ergonomic flexibility.

It is a straightforward, well-built tool without extras. Check battery availability for the long term, and sharpen or replace the blade when it dulls.

What works

  • 65Mn steel blade holds an edge and flexes on hard hits
  • 4,000mAh battery gives good runtime
  • Steel tube shaft is sturdier than plastic
  • Three depth settings cover common edging

Watch out for

  • Maximum 1.5 in depth is shallower than the ECOWORK
  • VEVOR is not a specialist outdoor tool brand

WORX WG163 20V 12 Inch 2-in-1 String Trimmer and Lawn Edger
12 in swath2-in-1Command Feed90 degree head tilt
Check price on Amazon
Best for: Homeowners who want one tool for string trimming and light line edging.

The WG163 is not a blade edger, it is a string trimmer that edges with line. Line edging is faster to set up and kinder on buried sprinkler heads, but it cuts a softer, wider edge than a steel blade and does not trench.

The head tilts 90 degrees, which also lets you trim on slopes, and rubberized wheels guide it for straighter lines. Command Feed lets you push a button to release more line. It uses the PowerShare battery family.

For tidy suburban edges that you maintain regularly, it is an effective one-tool solution. It is the wrong tool if you need a crisp, deep edge or want to cut a new border.

What works

  • One tool covers trimming and edging
  • Command Feed releases line with a button
  • Tilting head handles slopes and edges
  • Wheels help keep a straighter line

Watch out for

  • Line edging is softer and less crisp than a steel blade
  • Cannot trench or cut a new border

Spec sheet decoder

What the numbers on the box really mean

The specs manufacturers lead with, translated into what they tell you about real-world performance.

Blade diameter

The width of the spinning blade, which sets how deep the cut can go and how much power the motor needs.

Watch forA 9 inch blade sounds better than 7, but on a 20V pack it drains the battery faster.

RPM

How fast the blade spins. Higher RPM cleans a cut but does not guarantee torque.

Watch forThe goodjob and ECOWORK quote 3,500 RPM no-load, which falls under soil load.

Brushless motor

A motor that uses electronic commutation, giving better efficiency and longer life.

Watch forOnly the WORX WG898 and Mayoki are brushless here.

Cutting depth

How far below the guide the blade can reach. Deeper settings suit trenching, shallow settings suit trimming.

Watch forMaximum depth in compacted soil is lower in practice than the listing suggests.

Tool only

A bare tool with no battery or charger, intended for people already on the platform.

Watch forAdd the cost of a pack and charger before calling it cheaper.

Methodology

How We Evaluated These 20V Cordless Lawn Edgers

Cutting capability

We compared blade size, motor type and depth range. The ECOWORK's 1.75 inch depth leads, and the WORX WG163's line edging trails on crispness.

Battery and runtime

We compared included battery capacity and motor efficiency. Larger packs on the ECOWORK and VEVOR lead, while the goodjob's 2.0Ah pair trails.

Weight and guidance

We compared stated weights, guide wheels and handle design. The goodjob's 4.5 pounds led and the WORX's dual wheels scored for tracking.

Ownership and support

We considered platform size and battery availability. The WORX PowerShare platform scored highest, and the lesser-known brands lower.

Owner feedback patterns

We read patterns in owner feedback for blade wear, battery fade and wobble. Where spec sheets and feedback disagreed, we weighted the feedback.

Blade Edger vs String-Line Edger

Blade edger

A steel blade slices a vertical channel, giving a crisp, deep edge that lasts. It handles trenching but throws more debris and needs more power. The WG898, goodjob, ECOWORK, Mayoki and VEVOR fall here.

String-line edger

Trimmer line turned on its side trims a softer, wider edge but is easy to use and safer around sprinkler heads. The WORX WG163 falls here.

If you want a crisp edge, pick a blade; if you want one tool for light trimming and edging, pick the line option.

For Establishing New Borders Specifically

Look for

Depth range, an efficient motor and a solid blade. New borders cut through thick sod and roots, so depth and power matter more than weight.

In this comparison

The ECOWORK gives up to 1.75 inches, and the VEVOR's 65Mn blade resists hard hits. The brushless Mayoki helps if you already own DeWalt packs.

When to Spend More

Spend more if

You edge often or have long runs. The brushless WORX WG898 on a larger PowerShare pack gives more control and efficiency.

Save if

You edge a small yard a few times a year. The goodjob kit or the Mayoki with existing DeWalt packs does that job.

Ownership

Maintenance schedule

The upkeep that decides whether this machine lasts two seasons or ten.

TaskIntervalWhy it matters
Brush the blade cleanAfter every useSoil and grass stick to the blade and rust it. A quick wipe and a light oil prevents that.
Inspect the bladeEvery few sessionsA chipped or bent blade vibrates and cuts poorly. Replace damaged blades.
Check guide wheelsEvery seasonWorn wheels cause drift. Replace or tighten them.

FAQ

Frequently Asked Questions

Is a blade edger better than a string trimmer for edging?

For a crisp, lasting edge, yes. A string trimmer edges softly and is more forgiving around sprinklers. Choose by the edge you want.

How much should I spend?

Tool-only units cost less if you own the platform. Full kits cost more but include batteries. Count batteries in the total.

How long will the battery last?

A 2.0Ah pack covers a modest edge, and a 4.0Ah pack roughly doubles that. Light-load figures will not hold in compacted soil.

Does a bigger blade cut better?

It cuts deeper but demands more power. On a 20V pack a smaller blade can be more practical.

Can a 20V edger cut through roots?

Thin roots yes, thick roots no. A hardened blade like the VEVOR's 65Mn steel helps, but heavy roots stall the motor.

What safety gear is needed?

Wear eye protection and sturdy shoes. Edgers throw soil and stones, so keep people and pets away.
