Cordless mower listings tend to lead with a voltage number, but voltage alone does not tell you how long a mower will run. Watt-hours, which is voltage multiplied by amp-hours, is the figure that actually approximates stored energy, and it is worth checking against the included battery rather than the largest pack the platform can technically accept.

A cordless mower also differs from a corded electric mower in ways beyond convenience. There is no cable to manage around beds and trees, but there is a charging workflow, a finite runtime per charge, and battery replacement cost to plan for down the line. We compared deck width, included battery capacity, self-propel draw, charging time, and price across six current cordless models so you can match capacity to your actual lawn instead of the biggest number on the box.

5 Criteria to Look For Before Buying a Cordless Lawn Mower

Key buying criteria so you get the right fit the first time.

Watt-hours, not voltage

Multiply the nominal voltage by the amp-hour rating of the included battery to get an approximate energy figure. A higher voltage platform with a small included pack can hold less actual energy than a lower-voltage mower with a larger pack.

Grass load changes runtime

Manufacturer runtime figures are usually measured under light, dry grass. Tall, damp, thick, or recently missed lawns draw more current per pass and will shorten the real runtime you get from any given pack.

Self-propel draws the same battery

A self-propelled drive shares stored energy with the blade motor rather than running on a separate battery. Slopes, higher drive speed, and heavier mowers will all reduce mowing time compared to the rated figure.

Charging workflow

Compare full charge time, whether the battery needs to cool before fast charging again, how many batteries are included, and whether a second charger is worth buying to keep one pack topped up while another runs.

Cordless vs. corded tradeoff

A cordless mower removes the extension cord but adds a finite runtime per charge and an eventual battery replacement cost. A corded mower has unlimited runtime tethered to an outlet but no battery to plan around. Choose based on which constraint fits your yard and outlet access better.

EGO Power+ 21-Inch Cordless Lawn Mower (LM2114)

EGO Power+ 21-Inch Cordless Lawn Mower (LM2114)
21-inch deck56V battery platformBattery and charger includedPush drive

About this pick

The LM2114 pairs a full 21-inch deck with EGO's 56V battery platform, and it ships complete with a battery and charger rather than requiring a separate purchase to get running. It is backed by a 4.5 rating across more than 2,100 reviews, which is a large enough sample to take seriously for a single-model mower at this price.

For a standard-size, mostly flat lawn, the deck width and included pack are enough to finish a typical mow in one charge for most yards. It is a push mower, not self-propelled, so hilly or larger lots will feel the difference compared to the self-propelled options below.

Best for: standard-size lawns that want a full-width cordless deck without buying the battery separately

Check price on Amazon

Pros

  • +Full 21-inch deck for faster coverage
  • +Battery and charger included in the box
  • +Strong review volume backing the 4.5 rating

Cons

  • โˆ’Push drive only, no self-propel
  • โˆ’Included watt-hours should be checked against your lawn size before buying
Best Self-Propelled

Greenworks 80V 21-Inch Self-Propelled Mower

Greenworks 80V 21-Inch Self-Propelled Mower
21-inch deck80V 4Ah batterySelf-propelled driveBattery and charger included

About this pick

This Greenworks model steps up to an 80V 4Ah pack and adds a self-propelled drive, which matters most on sloped yards or for anyone who mows a larger area in one session. It holds a 4.5 rating, and while its review count (under 600 at time of writing) is smaller than the EGO's, the rating itself is consistent with the higher-voltage Greenworks line generally.

Self-propel draws energy from the same pack that powers the blade, so actual runtime under load will land below what a push-only mower with an identical pack would deliver. Anyone comparing this to a push mower purely on voltage should account for that tradeoff, not just the higher number.

Best for: sloped or larger lawns where self-propel meaningfully reduces walking effort

Check price on Amazon

Pros

  • +21-inch deck with self-propelled drive
  • +Higher-capacity 80V 4Ah included pack
  • +4.5 rating

Cons

  • โˆ’Self-propel draws energy that would otherwise extend blade runtime
  • โˆ’Smaller review sample than the top pick

20-inch deck48V (24V x 2) battery bayIncludes string trimmer and 320 CFM blowerThree batteries and chargers included

About this pick

This kit bundles a 20-inch cordless mower with a string trimmer and a 320 CFM blower, running off a dual 24V bay that totals to a 48V platform, and it ships with three batteries plus chargers so all three tools can be kept charged in rotation. Its early rating sits at 4.7, though the review count is still very small, so treat that number as an early signal rather than a settled track record.

For a buyer replacing several separate gas tools with one battery ecosystem, the shared-battery design is the real value, not just the mower on its own. Anyone who only needs a mower will likely get better per-tool value from a standalone model.

Best for: buyers who want a mower, trimmer, and blower on one shared battery platform

Check price on Amazon

Pros

  • +Mower, trimmer, and blower share one battery system
  • +Three batteries and chargers included
  • +Early 4.7 rating

Cons

  • โˆ’Review count is still too small to treat as a reliable track record
  • โˆ’Higher upfront price than a mower-only purchase

Greenworks 40V 16-Inch Cordless Push Mower

Greenworks 40V 16-Inch Cordless Push Mower
16-inch deck40V 4Ah batteryBattery and charger includedPush drive

About this pick

The 40V 16-inch model is Greenworks' smaller-deck, lower-voltage option, and it is backed by a 4.2 rating across more than 12,000 reviews, the largest review sample of any product in this guide. That volume is worth weighing alongside the rating itself when comparing mowers at this price.

The narrower 16-inch deck means more passes to cover the same area compared to a 21-inch mower, which makes the most sense on a small lot or as a second mower for tight corners. Buyers already invested in Greenworks 40V tools can also share batteries across the platform.

Best for: small lawns and buyers already invested in Greenworks 40V battery tools

Check price on Amazon

Pros

  • +Largest review sample in this comparison at over 12,000 reviews
  • +Compatible with the wider Greenworks 40V tool lineup
  • +Lower price than the 21-inch models

Cons

  • โˆ’16-inch deck means more passes on a mid-size or larger lawn
  • โˆ’Push drive only

SEYVUM 40V 16-Inch Cordless Lawn Mower

SEYVUM 40V 16-Inch Cordless Lawn Mower
16-inch deck40V with dual 4Ah batteries45L collection bagPush drive

About this pick

The SEYVUM comes with two 4Ah batteries rather than one, so a depleted pack can be swapped mid-mow instead of waiting through a full charge cycle. It carries a 4.3 rating, though the review count is still small, so it is worth reading a handful of recent reviews before relying on that number for a purchase decision.

At under $200 with two included batteries and a 45L bag, it is priced below every other mower in this guide. The 16-inch deck and lesser-known brand are the tradeoffs against the more established Greenworks and EGO options above.

Best for: budget-conscious buyers who want a spare battery included from the start

Check price on Amazon

Pros

  • +Two 4Ah batteries included, so one can charge while the other runs
  • +Lowest price in this comparison
  • +45L collection bag included

Cons

  • โˆ’Small review count relative to the established brands here
  • โˆ’16-inch deck limits coverage per pass

18-Inch 40V Brushless Cordless Push Lawn Mower

18-Inch 40V Brushless Cordless Push Lawn Mower
18-inch deck40V brushless motorPush driveLightweight frame

About this pick

This mower pairs an 18-inch deck with a brushless 40V motor at the lowest price point in this guide outside the SEYVUM. Its rating sits at 3.4 from a modest review count, noticeably lower than every other product here, so it is worth reading recent reviews closely before buying rather than relying on the deck size and price alone.

A brushless motor is generally more efficient and longer-lived than a brushed one, which is a genuine upside on paper. Given the below-average rating, this is more of a backup option if the higher-rated mowers above are unavailable or over budget.

Best for: buyers who need the lowest entry price and are comfortable with a lower-rated option

Check price on Amazon

Pros

  • +Brushless motor for efficiency and longevity
  • +Lowest price point alongside the SEYVUM
  • +18-inch deck is wider than the 16-inch budget options

Cons

  • โˆ’3.4 rating is noticeably lower than every other product in this guide
  • โˆ’Review count is small enough that the rating could shift

How We Evaluated These Cordless Lawn Mowers

Each pick was assessed across 4 criteria weighted for real-world use.

Battery capacity and platform fit

We compared included watt-hours rather than headline voltage, and noted where a listed voltage came from a dual-battery bay rather than a single higher-voltage pack.

Deck width and lawn size

We matched deck width against the coverage each mower is realistically suited for, since a narrower deck needs more passes to finish the same lawn.

Drive type and terrain

We separated push and self-propelled models and noted where self-propel draws down the same battery that powers the blade, since that tradeoff matters more on slopes.

Rating and review volume

Where a real rating and review count were available, we weighed the review sample size alongside the rating itself rather than treating every star rating as equally reliable.

Understand the Power Tradeoffs

Higher voltage platform

Usually means more available power and often a larger included pack, but check the actual watt-hours rather than assuming voltage alone predicts runtime.

Self-propelled drive

Reduces pushing effort on slopes and larger lawns, but shares the same battery as the blade, so expect shorter mowing time than a push-only mower with the same pack.

Dual or spare batteries

Lets you swap a depleted pack mid-mow instead of waiting through a full charge, which matters most on larger lawns or when the included pack alone won't finish in one charge.

Before and After Mowing

Before mowing

Confirm the battery is fully charged, check the deck for debris, and clear the lawn of sticks or rocks that could damage the blade.

After mowing

Recharge the battery promptly, clear clippings from under the deck, and store the mower somewhere dry to protect the electronics and battery contacts.

Frequently Asked Questions

What should I check before buying a cordless lawn mower?

Measure your lawn size, check the included battery's watt-hours rather than just the voltage, decide whether you need self-propel for slopes, and confirm the deck width matches how much coverage you want per pass.

Is a higher voltage always better?

Not by itself. Voltage times amp-hours gives an approximate energy figure, and a lower-voltage mower with a larger included pack can outlast a higher-voltage mower with a small pack. Always check the actual watt-hours of what ships in the box.

How much does self-propel affect runtime?

Self-propelled drive pulls energy from the same battery that powers the blade, so runtime under a self-propelled load is typically shorter than the same pack would deliver on a push-only mower, especially on slopes or at higher drive speeds.

Should I buy a mower with two included batteries?

A second included battery lets you swap packs mid-mow instead of waiting through a full charge, which is most useful on larger lawns where one pack won't finish the job. For a small lawn, a single well-sized pack is often enough.

How is a cordless mower different from a corded one?

A cordless mower has no cable to manage but a finite runtime per charge and an eventual battery replacement cost. A corded mower has unlimited runtime but requires an outlet and extension cord within reach and a mowing pattern that keeps the cable clear of the blade.
