Battery mowers have grown up. The 2026 crop of cordless walk-behinds handles real suburban lawns without the gas-can shuffle, and most now come with a rear collection bag as standard. I pulled four popular models that ship with a bag or bagging kit, each at a different size, power, and price tier, so you can match a mower to your yard rather than the other way around.
The Choices Worth Comparing
Greenworks 80V 21in Push Lawn Mower
Casince 17in Cordless Walk Behind Mower
EGO POWER+ 21in Self-Propelled Mower (LM2135SP)
Litheli 40V 16in Brushless Push Mower
A Closer Look At Each Pick
The Greenworks 80V is the one I keep coming back to when someone asks about a no-fuss, big-yard cordless mower. The 21-inch steel deck covers ground quickly, and the brushless motor delivers more torque than older brushed designs while running noticeably quieter. A brushless motor means no carbon brushes to wear out, which generally translates into longer motor life and less maintenance.
Single-lever height adjustment lets you move all four wheels at once instead of twisting four knobs, and the included 4.0Ah battery is rated for up to 60 minutes of runtime under typical conditions. Owners commonly report a full suburban lot (around a quarter acre) finishing on one charge, with thicker grass pulling runtime down. The rapid charger tops the pack back up in roughly an hour, so a lunch-break recharge is realistic.
Standout Benefits
- Wide 21-inch steel deck finishes a typical quarter-acre lot in fewer passes
- Brushless motor runs quieter and lasts longer than brushed alternatives
- Single-lever height adjust saves time versus four-wheel cranking
- 60-minute runtime covers most medium yards without a mid-mow recharge
- Sturdy steel deck holds up to curbside storage and frequent use
Things To Consider
- It’s a push mower, no self-propelled drive, so sloped lawns take more effort
- Steel deck adds weight versus plastic-deck models, which matters during storage
- Bag capacity fills fast on overgrown lawns and needs frequent emptying
Key Specs
Who It Suits Best
Homeowners with flat to gently rolling quarter-acre yards who want a wide deck, quiet brushless power, and a rear collection bag without stepping up to self-propelled pricing.
Consider Something Else When
Pick the EGO POWER+ 21in Self-Propelled Mower (LM2135SP) instead if your lot has noticeable slopes or you’re regularly mowing half an acre or more.
The Casince 17-inch sits in a useful middle spot for tight yards where the Greenworks deck would feel oversized. The narrower deck slips through shed gates and around raised beds more easily, and the dual 20V battery system (where two batteries run in series to deliver 40V total) stretches runtime up to about 40 minutes. That’s enough for roughly 5,380 square feet of coverage in average grass, which covers most city-sized lots in one pass.
Six height settings from 1 to 3 inches let you dial in anything from a close-cropped look to a lusher summer cut, and the rear collection bag keeps clippings off the sidewalk. Compared to the Greenworks above, this one trades deck width for maneuverability, which matters more than raw speed on a postage-stamp lawn.
The Good Stuff
- 17-inch deck is easier to maneuver around tight landscaping
- Dual-battery system stretches runtime to roughly 40 minutes
- Six height positions offer a finer cut adjustment than three-step levers
- Lighter weight makes storage up a basement stair much simpler
Worth Noting
- Smaller deck means more passes on larger lawns
- Both batteries must be installed to operate, no single-battery fallback
Made For
Townhouse and small-lot homeowners with under 2,000 square feet of grass who value maneuverability over deck width.
Skip It When
Go with the Greenworks 80V 21in Push Lawn Mower if your yard is wide and open, where a 21-inch deck will save you real time each mow.
The EGO POWER+ LM2135SP is the one I’d point a tired homeowner toward. It’s self-propelled, meaning the rear wheels drive themselves, so slopes and thick grass stop being a workout. The 56V platform delivers up to 7.0 ft-lbs of cutting torque, comfortably in gas-mower territory, and the Select Cut multi-blade system uses interchangeable lower blades for mulching, bagging, or extended runtime. The High Lift Bagging Blade ships as part of the bagging setup, lifting clippings cleanly into the rear bag.
This bundle pairs the 7.5Ah primary battery with an extra 5.0Ah pack (which may ship separately), effectively giving you two batteries to swap between. For anyone mowing half an acre or more, that swap strategy is the difference between finishing the lawn and stopping halfway to charge. Compared to the Greenworks above, you’re paying for the self-propelled drive, the higher-voltage platform, and the modular blade system.
Notable Upsides
- Self-propelled drive handles hills and thick grass with far less fatigue
- Select Cut blade system swaps between mulching, bagging, and runtime modes
- 56V battery platform delivers gas-comparable torque
- Bundled extra battery extends total runtime for larger properties
Trade Offs
- Premium-tier pricing versus simpler push mowers
- Extra battery ships separately and needs a second charge cycle before use
- Heavier than non-propelled models, which can matter on stairs
Who Should Grab It
Homeowners with sloped lawns, half-acre-plus lots, or anyone who wants self-propelled drive and modular cutting modes in one package.
Look Elsewhere When
Choose the Litheli 40V 16in Brushless Push Mower if you’re mowing a flat, small yard and want the lightest carry and simplest controls at a friendlier price.
The Litheli 40V is the friendliest pick on this list for first-time mower owners. The 16-inch deck keeps the whole machine light enough to carry out of a shed or up a stoop, and the brushless motor skips the oil changes, spark plugs, and carburetor fuss of a gas engine. Maintenance stays limited to blade sharpening, bag emptying, and an occasional under-deck scrape, which is exactly the simplification most suburban shoppers actually want.
Six cutting heights from 25 to 75 mm give you genuine flexibility, from a low tidy cut to a taller summer setting that helps drought-stressed grass. The 50-liter collection bag is generous for the deck size, so you empty less often than you’d expect. Both 5.0Ah batteries need to be in place for the mower to run, and the 40V output stays steady throughout the cut. Compared to the Casince above, this one has a slightly smaller deck but a larger collection bag, and the brushless motor should outlast a brushed design over years of weekly use.
Well-Handled Touches
- Brushless motor means no spark plugs, oil, or carburetor upkeep
- Six height settings from 25 to 75 mm cover most grass types and seasons
- Generous 50-liter bag reduces emptying stops
- Lightest deck in this lineup makes storage and transport simple
Points To Note
- 16-inch deck means more passes than the wider Greenworks or EGO
- Both batteries must be installed, no single-pack fallback option

Another Choice May Suit
Pick the EGO POWER+ 21in Self-Propelled Mower (LM2135SP) if you want self-propelled drive and a wider deck that finishes larger lawns in fewer passes.
What To Weigh Before Choosing Your Next Mower
Deck Size and Yard Match
A wider deck finishes a yard in fewer passes, but only if you can maneuver it. For a flat, open quarter-acre, a 21-inch deck saves real time. For a fenced backyard with narrow side gates and flower beds, a 16 or 17-inch deck is the more honest match. Picking the widest mower you can actually push around your obstacles is the quiet trick most shoppers miss.
Battery Platform and Runtime Reality
Voltage matters less than the actual amp-hour (Ah) rating, which measures how much energy the battery stores. A 4.0Ah pack at any reasonable voltage will outlast a 2.0Ah pack of the same voltage, because Ah is essentially fuel-tank size. For a quarter-acre, look for at least a 4.0Ah pack with a rapid charger. For a half-acre or more, a dual-battery setup or a swappable spare is the practical answer.
Bagging, Mulching, or Both
If you prefer a tidy lawn with no clippings left behind, a true bagging blade and a generously sized rear bag matter. The EGO POWER+ ships with a High Lift Bagging Blade as part of its bagging mode, and the Litheli’s 50-liter bag is unusually roomy for a 16-inch deck. If you want the option to mulch on slow-growth weeks, look for a model with interchangeable blades, like the EGO Select Cut system.
Drive Type and Terrain
Self-propelled drive, where the rear wheels pull the mower forward under their own power, is worth the upgrade for slopes, thick grass, or anyone who mows more than a quarter acre. Flat, small yards rarely justify the extra cost. The Greenworks and Litheli are honest push mowers that reward smaller, level lawns.
Across The Four Picks At A Glance
Mistakes Worth Dodging
Choosing a deck that won’t fit through your side gate is the classic first-time error. Measure the narrowest passage your mower has to clear, including any fence latch overhang, before you commit to a 21-inch deck. Another common slip: assuming all brushless motors are equal. They share the no-brush design, but build quality and controller electronics still vary, so a known platform with available spare batteries is worth more than a slightly cheaper no-name alternative.
Where The Extra Money Goes
Stepping up from a basic 16-inch push mower to something like the EGO POWER+ self-propelled bundle gets you drive assist, a higher-voltage platform, swappable batteries, and a modular blade system. The case for paying more is straightforward: if your yard has slopes, runs over a quarter acre, or you want genuine bagging plus mulching in one machine, the premium tier pays for itself in saved time and reduced fatigue. For a flat small lot, the simpler Litheli or Casince models will cover the same ground without the extra spend.
Frequently Asked Questions
How long does a cordless mower battery actually last per charge?
Most cordless mowers in this class run 30 to 60 minutes per charge, depending on grass thickness, deck size, and battery capacity. Wet or overgrown grass pulls runtime down noticeably, while dry, well-maintained lawns let you stretch closer to the rated maximum.
Can I leave the collection bag on while mowing in the rain?
Wet grass clumps and clogs the bagging chute quickly, so mowing wet lawns with the bag attached leads to frequent stops and a heavier bag to empty. Letting the lawn dry first gives you a cleaner cut and a much easier post-mow cleanup.
Do these mowers come with a charger, or is that sold separately?
All four mowers in this roundup ship with at least one charger in the box, and the Greenworks, Casince, and Litheli bundles include batteries as well. The EGO POWER+ bundle adds a second battery that may ship separately, so check the listing details if you want both packs ready on day one.
How do I store a cordless mower over winter?
Most owners remove the battery, give the deck a quick scrape, and store the whole machine in a dry shed or garage. Lithium-ion batteries prefer to be stored at partial charge rather than fully drained or fully topped up, somewhere around 40 to 60 percent is a sensible target.
Are cordless mowers powerful enough for thick or tall grass?
Modern 56V and 80V platforms deliver gas-comparable torque, and self-propelled models handle thick grass with less effort. Cutting more than a third of the blade length at a time still stresses any mower, so taller lawns benefit from a two-pass approach.
The Takeaway
The right mower is the one that fits your yard, your storage spot, and your tolerance for fuss. A small flat lawn doesn’t need the premium tier, and a wide sloped lot will reward every dollar spent on self-propelled drive and a higher-voltage battery. Match the mower to your grass and you’ll stop thinking about it after every cut, which is exactly the point.
