Cordless mowers have reshaped weekend yard work. No gas cans, no tangled cords, and noticeably quieter runs mean you can mow before coffee without waking the block. The trade-off shows up in battery life and torque, so the right pick depends on lawn size, grass type, and how much slope you tackle. This roundup focuses on six solid walk-behind options built for suburban lawns, comparing deck size, voltage, and runtime so you can match a machine to your yard instead of the other way around.
A Fast Comparison Of The Options
Greenworks 80V 21in Push Lawn Mower, 4.0 Ah Battery and Charger
Casince 17in Walk Behind Cordless Lawn Mower
EGO POWER+ LM2135SP 21in Self-Propelled Mower
Worx WG733.1 20V 14in 2-in-1 Lawn Mower

More On The Choices That Made The List
The Greenworks 80V push mower lands at the top of this roundup because it threads a useful middle line between price and capability. The 21-inch deck covers a lot of ground per pass, which matters on rectangular suburban lots where every extra inch saves minutes. A brushless motor (a motor with no physical brushes, so it runs cooler and lasts longer) keeps noise down and torque up compared with brushed designs. You get a single-lever height adjustment that moves the whole deck through its range, instead of adjusting each wheel separately.
For most backyards running under a third of an acre, runtime lands somewhere in the 45-to-60-minute window depending on grass thickness and how much you throttle. The included 4.0Ah battery and rapid charger (charging in roughly 60 minutes based on the listed spec) make midweek top-ups painless. The trade-off is that this is a push model, so any meaningful slope will test your legs.
Advantages To Know
- Steel 21-inch deck holds up to bumps and rougher patches better than plastic alternatives.
- Brushless motor delivers quieter operation and longer service life, useful for early-morning mowing.
- Single-lever height adjustment makes switching between grass lengths fast.
- Rapid charger restores the 4.0Ah pack in about an hour, handy between weekend cuts.
- 80V platform shares batteries with other Greenworks tools, useful if you already own into the ecosystem.
Things To Consider
- Push design without self-propel, which can tire you out on larger or hillier yards.
- Steel deck adds weight, so storage and transport take a bit more effort.
- One included battery means longer sessions require a charged spare on hand.
Who It Suits Best
Homeowners with a flat, mid-size suburban lawn who want a durable deck and quiet operation without paying for self-propulsion.
Consider Something Else When
Pick the EGO POWER+ LM2135SP 21in Self-Propelled Mower instead, since hilly or larger lawns benefit from motor-driven rear wheels that the Greenworks lacks.
The Casince 17-inch cordless mower is built for tidy small-yard work where agility matters more than raw deck width. Two 20V 4.0Ah batteries work together to extend runtime up to around 40 minutes, depending on grass length and terrain. You also get six height settings ranging from 1 to 3 inches, which covers everything from a clean short cut to longer summer grass. The 17-inch deck trims a smaller strip per pass than the Greenworks, so larger lots require more walking.
Where this mower shines is storage and handling in tight spaces, like fenced side yards and narrow gates. The dual-battery setup means one pack can charge while the other runs, useful for two-stage mowing sessions. For most flat lots under 5,000 square feet, the listed coverage figure of roughly 5,380 square feet per charge lines up with realistic use.
Everyday Advantages
- Compact 17-inch deck fits through narrow gates and tight side-yard passages.
- Dual-battery system extends runtime and lets one pack charge while the other works.
- Six height settings between 1 and 3 inches cover varied grass preferences.
- Lighter overall weight makes it easier to carry up basement or shed steps.
Worth Noting
- Smaller deck means more passes on bigger lawns.
- Best suited to flat terrain since it lacks self-propel and high torque.
- Two batteries to manage, charge, and store over time.
Made For
Anyone with a small, flat yard under 5,000 square feet who values easy storage and lighter handling over maximum cutting width.
Look Elsewhere When
Skip toward the Greenworks 80V 21in Push Lawn Mower if your lawn stretches past a quarter acre, since the wider deck saves real time per mow.
The EGO POWER+ LM2135SP is the machine on this list that closes the gap with gas mowers. Self-propelled rear-wheel drive (the mower drives its own rear wheels, so you guide rather than push) takes the strain out of sloped or thick grass, and the 56V 7.5Ah battery pushes torque high enough to handle damp spring growth. You also receive an extra 5.0Ah battery, so runtime becomes a swap-and-go affair rather than a charge-and-wait situation.
The Select Cut multi-blade system (three interchangeable blades for mulching, bagging, or extended runtime) sits at the center of the value here. You can match the blade to the task, which is rare at this price tier for cordless. Compared to the Greenworks earlier in this list, this is the upgrade pick when slope and grass variety push you past what a push mower can comfortably deliver.
What Earns Its Place
- Self-propelled drive reduces fatigue on slopes and longer sessions.
- Select Cut multi-blade system supports mulching, bagging, or extended runtime with a blade swap.
- Two batteries included, useful for back-to-back cuts without waiting on a charger.
- 56V platform delivers torque comparable to small gas engines.
Trade Offs
- Higher cost than push-only options like the Greenworks.
- Heavier build, which complicates storage in small sheds or upstairs garages.
- Bundled extra battery may ship separately, so plan for two arrivals.

Skip It When
The Worx WG733.1 20V 14in 2-in-1 Lawn Mower fits better for tiny, flat gardens where self-propulsion adds weight without real benefit.
The Worx WG733.1 is the smallest mower in this roundup, and that is the entire point. A 14-inch deck and a single 20V 5.0Ah PowerShare Pro battery (which is cross-compatible with other Worx 20V tools) keep weight low and storage simple. It is the easiest of the six picks to carry up apartment stairs or stash in a closet between mows. Coverage on a single charge reaches around 3,200 square feet based on the listed spec, which fits a small urban yard or a side-yard strip.
The 2-in-1 deck switches between mulching and bagging without tools, which is convenient for homeowners who alternate between fertilizing the lawn and clearing clippings. You may find the 14-inch width restrictive on bigger lots, since passes stack up faster than with the Greenworks or EGO. Compared to the Casince reviewed earlier, this trades deck width for a smaller footprint and lighter feel.
The Value In It
- Ultra-compact 14-inch deck fits tight storage and narrow access paths.
- PowerShare Pro battery works across the Worx 20V tool family.
- Lightweight build reduces fatigue and simplifies transport.
- 2-in-1 mulching or bagging without extra attachments.
Minor Gripes
- Narrow deck means more passes on larger lawns.
- Lower voltage translates to weaker performance in tall, wet grass.
Perfect Match For
Apartment and townhouse owners with small lawns or narrow side yards who need a mower that disappears into a closet.
Reach For A Different Pick When
The Casince 17in Walk Behind Cordless Lawn Mower is the smarter swap for small flat lots over 2,000 square feet where extra deck width saves time.
The Honda HRX-BE brings Honda engineering into the cordless category with a battery platform designed to mirror the torque profile of the company’s gas GCV engines. The result is a mower that holds RPM (rotational speed of the blade) under load, which translates to a cleaner cut through dense patches. The Versamow system with Clip Director (a lever that switches between mulching and bagging without tools) lets you mulch, bag, discharge, or shred leaves without swapping any hardware.
This is the right pick for homeowners who treat lawn care as a craft rather than a chore. Twin blades (two cutting blades stacked on a single spindle) improve mulching quality, and the 21-inch deck keeps pass count reasonable on larger lots. For most owners the real question is whether the premium over the EGO POWER+ LM2135SP pays off in build feel and long-term reliability rather than headline specs.
The Helpful Details
- Honda engineering targets gas-like torque for consistent cutting under load.
- Versamow system with Clip Director swaps modes without attachments.
- 4-in-1 capability covers mulching, bagging, discharging, and leaf shredding.
- Twin-blade design improves mulching fineness and cut quality.
Honest Caveats
- Premium pricing compared with other 21-inch cordless picks.
- Push configuration, so hilly terrain still demands effort.
- Battery and charger ecosystem is Honda-specific, limiting cross-brand flexibility.

Who Will Love This
Detail-oriented homeowners who want Honda build quality and versatile cutting modes for varied yard conditions.
Swap It Out When
Honda HRX-BV 21in Walk Behind Battery Mower makes more sense if you want the same Honda engineering with variable-speed self-propel for hilly ground.
The Honda HRX-BV is the most capable Honda in this roundup, layering variable-speed self-propel on top of the HRX platform. Cruise control-style speed adjustment lets you match walking pace to grass conditions, which reduces fatigue over long mowing sessions. The 21-inch deck, twin blades, and Versamow system carry over from the HRX-BE, so cut quality stays consistent across the Honda cordless line.
For homeowners with bigger or hillier lots, the variable-speed self-propel is the meaningful upgrade over the HRX-BE reviewed earlier. You may find the price premium harder to justify on flat, small lawns where push effort is minimal. Compared to the EGO POWER+ LM2135SP from earlier in this list, this is the heavier, more traditionally engineered option with Honda-specific battery compatibility.
Practical Advantages
- Variable-speed self-propel reduces fatigue on slopes and long sessions.
- Honda engineering targets gas-comparable torque for dense grass.
- Versamow system with Clip Director supports mulching, bagging, discharge, and leaf shredding.
- Twin-blade configuration produces fine mulch and even cuts.
- 21-inch deck keeps pass count reasonable on larger properties.
Where It May Fall Short
- Highest price point in this roundup.
- Heavier than the HRX-BE, so storage and transport take planning.
- Battery ecosystem is Honda-specific.
The Right Fit
Homeowners managing larger, sloped yards who want Honda build quality with motor-assisted drive and longer runtime comfort.
Where A Sibling Pick Shines
The Honda HRX-BE 21in Walk Behind Battery Mower suits smaller, flatter lots where self-propel adds cost without much benefit.
Matching Cordless Mower Specs To Real Yard Work
Deck Size And Lawn Coverage
The cutting deck is the metal or plastic housing that holds the blade, and its width decides how much grass you cut per pass. A 14-inch deck, like the one on the Worx WG733.1, navigates tight spaces easily but doubles your walking on a quarter-acre lot compared to a 21-inch deck. For most suburban yards between 3,000 and 8,000 square feet, a 17-to-21-inch deck hits the practical sweet spot. Larger properties benefit more from wider decks and self-propelled drive than from higher voltage alone.
Voltage, Amp-Hours, And Runtime
Voltage (V) describes the electrical pressure the battery delivers, while amp-hours (Ah) describe how much energy the pack stores. Higher voltage helps the motor push through thick or wet grass, while higher amp-hours extend runtime at a given power draw. The Greenworks 80V platform leans on voltage for torque, while the Casince dual-battery setup focuses on amp-hour capacity for runtime. Match voltage to grass toughness and amp-hours to lawn size, and you avoid the common trap of buying a mower that runs out of juice halfway through the back yard.
Drive Type And Terrain
Push mowers like the Greenworks 80V and Honda HRX-BE rely on your walking effort, which works on flat ground but punishes legs on slopes. Self-propelled models, including the EGO POWER+ LM2135SP and Honda HRX-BV, drive their own rear wheels so you guide rather than push. Variable-speed self-propel, like on the Honda HRX-BV, lets you match pace to slope and grass height. For hilly lots or anyone mowing half an acre or more, self-propel tends to feel less like a luxury and more like a back-saver.
Cutting Modes And Blade Systems
Mulching chops clippings finely and returns them to the lawn as natural fertilizer, while bagging collects clippings for a tidy look. Discharge sends clippings out the side, useful for tall grass where bagging fills up fast. The Honda Versamow system and EGO Select Cut multi-blade system let you swap modes or blades without separate attachments. Homeowners who switch between lawn feeding and cleanup benefit most from these flexible setups, while those who always mulch in one mode can ignore the extra hardware.
Key Considerations Across These Picks
Wrong Turns To Avoid
Buying on voltage alone is a common slip, since high voltage with a small battery still runs out fast on a big lawn. Another trap is choosing a 14-inch deck for a quarter-acre lot and ending up walking twice as far as needed. Finally, ignoring battery platform compatibility (whether batteries work across other tools you own) means you end up with chargers and packs that do not share with anything else in your garage.
Where The Extra Money Goes
Stepping up to a premium cordless mower, like the Honda HRX-BV, buys variable-speed self-propel, stronger torque retention under load, and more versatile cutting modes. For flat small yards, that extra money is hard to justify. On larger, sloped, or grass-heavy properties, the upgrade pays off in less fatigue, fewer battery swaps, and a cleaner cut through dense patches. The honest read is that mid-tier options like the Greenworks 80V and EGO POWER+ LM2135SP cover most suburban needs, and premium picks earn their price only when terrain or lawn size demands it.
Frequently Asked Questions
How long does a cordless mower battery last on a single charge?
Runtime varies from roughly 30 to 60 minutes depending on battery capacity, grass thickness, and whether you bag or mulch. Most packs in this roundup land in the 40-to-60-minute window under typical use, and the EGO POWER+ LM2135SP includes a spare battery to extend sessions further.
Can a cordless mower handle wet or thick grass?
Higher-voltage platforms like the 80V Greenworks and 56V EGO POWER+ handle damp growth better than lower-voltage options. Still, mowing wet grass is harder on any mower and reduces runtime, so letting the lawn dry first helps both cut quality and battery life.
Are cordless mowers powerful enough for large lawns?
Yes, especially self-propelled models with 56V or 80V batteries like the EGO POWER+ LM2135SP or Honda HRX-BV. For lots over half an acre, plan on a spare battery or a quick-charging setup so you can finish without long pauses.
How do I maintain a cordless mower?
Keep the deck clean of caked grass after each use, sharpen or replace blades once a season, and store batteries at room temperature rather than in a hot shed. Brushless motors, like the one in the Greenworks 80V, generally require less service than brushed designs.
What is the difference between mulching and bagging?
Mulching chops clippings finely and drops them back into the lawn to feed the soil, while bagging collects clippings for disposal or composting. Many cordless mowers in this roundup, including the Honda HRX series and EGO POWER+ LM2135SP, support both modes with a quick lever or blade swap.
Bottom Line
The right cordless mower comes down to lawn size, slope, and how much runtime comfort matters. Small flat yards do well with the Worx WG733.1 or Casince 17-inch, while mid-size lots benefit from the Greenworks 80V push mower. Larger or sloped properties get the most out of self-propelled picks like the EGO POWER+ LM2135SP and Honda HRX-BV, with Honda build quality reserved for those who want long-term engineering over headline specs. Match the mower to your yard, not the other way around, and the rest of the season tends to take care of itself.
