A push mower that fires up with a button press and folds down to fit a closet changes the whole rhythm of yard care. For townhouse lawns, postage-stamp backyards, and anyone tired of storing a rattly gas engine, compact cordless walk-behinds handle real mowing in a fraction of the space. I looked at eight walk-behind mowers built for small to mid-size lawns, comparing deck size, battery platform, cut height range, and the everyday storage quirks that matter once the grass is done. The shortlist spans ultralight 20V units, brushless 40V workhorses, and Honda’s full-feature battery deck.
A Quick View Of The Lineup
MZK 20V 13-Inch Electric Lawn Mower, Brushless
Worx WG733.1 20V 14-Inch Cordless Mower
Worx WG735 40V 14-Inch Cordless Mower
Worx WG745 40V 17-Inch Cordless Mower
Honda HRX-BE 21-Inch Battery Mower

BLACK+DECKER BEMW213 20-Inch Corded Mower
Wild Badger Power 40V 14-Inch Brushless Kit
A Closer Look At Each Pick
For a townhouse backyard or a side strip of grass no wider than a parking space, the MZK 20V 13-Inch is built to disappear into the shed when you’re done. The 13-inch deck slips through fence gates that swallow wider mowers, and the brushless motor (a motor that uses electronic instead of brush contacts, so it runs cooler and lasts longer) is rated for up to 3400 RPM on its higher setting. That kind of headroom matters when the grass gets a week past “due” and turns fibrous.
It runs on a 20V platform, so the battery is swappable across MZK’s other handheld tools, and the four-position height range covers most lawn types. Compared with the Worx WG733.1 sitting just below it on this list, the MZK trades some deck width for an even tighter footprint, which I appreciate for the kind of lawn where every pass is a pivot.
Everyday Wins
- Brushless motor means less heat buildup during longer sessions, which generally extends motor life compared to brushed designs.
- Four-position cut height adjustment from roughly 1.3 to 2.6 inches covers typical seasonal growth without fiddling.
- 13-inch deck fits gates and sheds where 17- or 20-inch mowers won’t go, a real benefit for older fences.
- Bagging mode keeps clippings off walkways, useful for keeping decks and patios tidy.
- 20V battery platform swaps into other tools in the same family, reducing charger clutter.
Things To Consider
- The 13-inch deck means more passes on anything over a small patch, and runtime may feel tight on bigger jobs.
- Cut height range tops out near 2.6 inches, which can feel limiting if you prefer a taller summer cut.
Made For
Homeowners with narrow gates, sloped side yards, and lawn footprints under about 1,500 square feet who prioritize storage over speed.
Consider Something Else When
The Worx WG745 40V 17-Inch Cordless Mower fits better for anyone managing closer to a quarter acre who wants fewer passes per mow.
The Worx WG733.1 is the kind of mower someone gifts a first-time homeowner, and that’s a compliment. The 20V 5.0Ah PowerShare Pro battery (a shared-battery design that runs across Worx’s 20V and 40V tools) covers yards up to about 3,200 square feet on one charge, which is roughly the average city lot’s worth of grass. The 14-inch deck splits the difference between the MZK’s tight 13-inch cut and the wider 17-inch option further down this list.
Where it really earns its keep is the simplicity: one battery, one charger, push-button start, and a 2-in-1 mulch-or-bag deck (mulching chops clippings finely so they feed back into the lawn; bagging collects them for disposal). For someone trading in a temperamental gas mower for their first electric, the learning curve is refreshingly short.
Where It Helps
- Brushless motor delivers longer runtime and quieter operation than brushed units in the same class.
- PowerShare battery works across 140-plus Worx tools, which reduces battery sprawl over time.
- 2-in-1 mulching and bagging in one deck means fewer attachment swaps mid-job.
- Push-button start removes the primer-and-cord ritual of small gas engines.
Points To Keep In Mind
- A single 20V battery won’t carry the deepest, thickest St. Augustine or Bermuda lawns without a recharge pause.
- 14-inch deck is still narrower than a standard walk-behind, so larger yards take noticeably more passes.
- Plastic deck construction is lightweight for storage but can scuff if dragged across rough surfaces.
Who It Suits Best
First-time mower owners with a small, mostly flat lawn who already own, or plan to own, other Worx 20V tools.
A Better Fit Elsewhere
The Wild Badger Power 40V 14-Inch Brushless Kit covers similar ground but adds a 40V platform for tougher grass, which matters for Bermuda or zoysia lawns.
The WG735 takes the WG733.1’s friendly footprint and bolts on more muscle. IntelliCut is the headline feature: it senses grass density and bumps torque on the fly, so the blade doesn’t bog down in the lush patches after rain. For renters and condo owners with a shared lawn strip, that’s the difference between a clean cut and the embarrassing half-mowed look.
On a single 4.0Ah battery, Worx rates coverage up to about 1/8 acre, which lines up with most apartment-adjacent yards. The deck design routes airflow to lift blades upright before cutting, and the larger rear bag means fewer dump trips. Compared with the WG733.1, the step up pays off most when the lawn grows unevenly across sunny and shaded zones.
The Helpful Details
- IntelliCut torque management prevents the blade from stalling in thick spots, a common frustration with smaller cordless mowers.
- Optimized deck airflow lifts grass for a cleaner, more even cut.
- Rear bag holds more clippings, reducing interruptions on longer sessions.
- PowerShare battery stays compatible with the broader Worx ecosystem.
Trade Offs
- 40V battery adds a bit of weight over the 20V WG733.1, which can show up on hills.
- At 1/8 acre per charge, anyone with a larger lawn should budget for a second battery.
Quick Facts
Right Fit For
Apartment and townhouse dwellers with lawns around 1/8 acre, especially where grass thickness varies across the yard.
Skip It When
The Worx WG745 40V 17-Inch Cordless Mower is the better match for quarter-acre lots that need wider coverage per pass.
Stepping up to a 17-inch deck cuts mowing time on anything resembling a quarter acre, and the WG745 adds dual-battery runtime to back that up. Two 20V 4.0Ah PowerShare batteries run in series for 40V output, and a dual-port charger refills both at once. The wider deck makes this the practical ceiling for “compact” cordless mowers without crossing into a much bigger storage footprint.
For homeowners managing up to a quarter acre, the WG745 feels closer to a gas replacement than the smaller Worx models. The tradeoff is bulk: it’s heavier and the deck takes up more shed space than the WG735. Battery interchangeability with 140-plus Worx tools remains a long-term money saver.
Notable Upsides
- 17-inch deck covers more ground per pass, shaving real time off quarter-acre lawns.
- Dual batteries deliver extended runtime without stopping to swap cells mid-mow.
- Brushless motor provides the torque needed for thicker grass without bogging.
- PowerShare batteries are shared across the Worx 20V and 40V lineup, simplifying charger count.
Points To Note
- Heavier than the 14-inch Worx models, which can wear on smaller-framed users.
- Larger deck means it won’t slip through every narrow garden gate.
- Two batteries and a dual charger take up more shelf space in the garage.
Best Suited To
Suburban homeowners with quarter-acre lawns who want gas-like coverage without the maintenance or fuel.
Look Elsewhere When
Honda HRX-BV 21-Inch Battery Mower fits better for anyone prioritizing a wider 21-inch deck and self-propelled drive on sloped terrain.
The HRX-BE is Honda’s answer to lawn keepers who want the cut quality of a premium walk-behind without the gas can in the garage. The 21-inch deck, twin blades, and Versamow system with Clip Director (a lever that adjusts how much grass is mulched versus bagged, without tools) put it in a different class than the smaller cordless units earlier in this list. Honda positions its battery motor output near its GCV-series gas engine, which is a meaningful benchmark.
The 4-in-1 design covers mulching, bagging, discharging, and leaf shredding, all controlled by a single lever. For homeowners who treat the lawn as a feature, not a chore, the flexibility is real. Compared with the WG745, the trade is deck width and Honda build quality against footprint and price.
Useful Strengths
- Versamow Clip Director adjusts mulching-to-bagging ratio on the fly, ideal for fall leaf cleanup mixed with grass.
- 21-inch twin-blade deck delivers a clean, finished cut across larger lawns in fewer passes.
- Battery motor is tuned to maintain RPM under load, matching Honda gas-engine benchmarks.
- Honda engineering typically translates to long service life and widespread parts availability.
Worth Noting
- 21-inch deck and overall footprint push the upper limit of “compact” for tight storage spaces.
- Battery and motor system represent a premium investment over 14-inch cordless picks.

Another Choice May Suit
Honda HRX-BV 21-Inch Battery Mower fits better for sloped lawns where variable-speed self-propulsion matters more than mulching flexibility.
The HRX-BV is the HRX-BE with a self-propelled twist: variable-speed drive lets the mower pace the operator instead of the other way around. On slopes, that translates to less fatigue and a more consistent cut line, because the blade speed stays steady even when the walking pace changes. For hilly suburban lots, this is the upgrade that earns its keep.
It carries the same 21-inch twin-blade deck, Versamow Clip Director, and 4-in-1 cutting system as the BE version. The trade-off is weight and cost: the self-propel drive adds pounds, and the unit sits at the top of this roundup’s size category. Anyone with a flat lot can save by sticking with the BE.
A Strong Showing
- Variable-speed self-propelled drive reduces fatigue on slopes and uneven terrain.
- 21-inch twin-blade deck and Versamow system match the HRX-BE’s cut quality.
- Battery motor maintains RPM under heavy grass loads, similar to Honda’s gas-engine benchmarks.
- 4-in-1 cutting system handles mulching, bagging, discharge, and leaf shredding in one deck.
Possible Compromises
- Self-propelled drive adds weight, making the unit less ideal for users who prioritize a lightweight push.
- Sits at the premium end of the roundup, and the extra cost only pays off on sloped or larger lawns.

Not Your Match When
Honda HRX-BE 21-Inch Battery Mower is the leaner alternative for flat lots where self-propelled drive adds cost without benefit.
The BEMW213 isn’t cordless, and that’s actually its hook. A 13-amp corded motor delivers continuous runtime, so there’s no battery to charge or replace. The 20-inch deck is the widest in this roundup, paired with a winged blade designed for better lift and collection. Six height settings from 1.5 to 4 inches cover more grass types than most of the cordless picks.
The constraint is the cord. Anyone whose yard extends beyond a 100-foot extension cord run will feel the tether. For a small yard with an outdoor outlet within reach, though, the BEMW213 sidesteps battery aging entirely. Compared with the Honda HRX series above, this is the pragmatic, low-fuss option.
Where It Delivers
- Continuous corded power means no battery degradation, mid-mow recharges, or replacement cells down the road.
- 20-inch deck covers a small yard in noticeably fewer passes than 14-inch cordless models.
- Six height settings from 1.5 to 4 inches handle everything from short Bermuda to taller fescue.
- Compact storage design folds down for shed and garage spaces.
Some Limits To Know
- Cord limits range and requires care to avoid running over the cable.
- Not battery-powered, so it falls outside the “cordless” framing for shoppers specifically avoiding cords.
- Lacks the mulching flexibility of Honda’s 4-in-1 Versamow system.

Reach For A Different Pick When
Worx WG733.1 20V 14-Inch Cordless Mower fits better for anyone who specifically wants cordless freedom over corded runtime.
Wild Badger Power built this kit for townhomes, narrow gates, and lawns cluttered with beds and trees. The 40V brushless motor tops out near 3,800 RPM, which is the highest no-load figure in this roundup, and the five-position height range from 1 to 3 inches spans most residential grass types. It’s sold as a complete kit, battery and charger included, which removes the usual add-on guesswork.
Compared with the Worx WG735, the Wild Badger trades IntelliCut torque management for raw RPM and a slightly broader height range. The 14-inch deck still slips through tight gates, and push-button start keeps the routine simple. For first-time cordless owners, the kit-complete approach is genuinely low friction.
The Good Stuff
- 40V brushless motor reaches up to 3,800 RPM, delivering strong cutting performance on weekly mowing schedules.
- Five cutting heights from 1 to 3 inches cover most seasonal adjustments without tools.
- Kit includes battery and charger, so there’s no separate accessory shopping.
- 14-inch deck navigates narrow gates and lawn furniture layouts without constant repositioning.
Where It Is Less Suited
- Single 40V battery may run short on larger lots without a second cell.
- Wild Badger Power is a newer brand in this category, so long-term service-network coverage is still developing.
Spec Overview
Whose Shelf It Belongs On
First-time cordless mower owners with narrow gates, tree-lined lawns, or beds that demand frequent directional changes.
Swap It Out When
Worx WG745 40V 17-Inch Cordless Mower fits better for quarter-acre lawns where a wider deck saves more time than gate clearance matters.
Choosing The Right Compact Cordless Mower For Your Yard
Deck width sets the pace of every mow, and the practical range here runs from 13 inches for tight gates up to 21 inches for quarter-acre lots. A 14-inch deck is the sweet spot for most small yards, balancing maneuverability with pass count. Battery voltage matters more than people expect: 20V platforms handle light weekly growth on cool-season grasses, while 40V systems keep torque steady on thick Bermuda, zoysia, or St. Augustine. Cut height range is the spec most shoppers overlook. Anything from about 1.5 to 3.5 inches covers the typical seasonal swing; models capped near 2.6 inches will feel limiting if you prefer a taller summer cut.
Weight And Storage Footprint
Cordless mowers live or die by how easy they are to lift into a shed or hang on a wall. Plastic decks keep weight down, which helps on slopes, but they scuff if dragged. Folding handles matter more than they sound. A mower that collapses flat fits beside a trash can instead of demanding a corner. For apartment dwellers with shared storage, the MZK 20V 13-Inch Electric Lawn Mower and the Worx WG733.1 20V 14-Inch Cordless Mower are the easiest to stash.
Battery Platform And Long-Term Cost
Cordless mowers live or die on their battery ecosystem. Worx PowerShare batteries slot across 140-plus tools, which spreads the cost of chargers and spares over years of yard work. Brands with single-product batteries leave you replacing the whole platform when the cell ages out. For anyone planning to add a trimmer, blower, or hedge tool, choosing a mower on the same battery platform quietly saves real money over time.
Cut Modes And Clipping Handling
Bagging keeps walkways tidy but adds dump trips. Mulching feeds clippings back into the lawn as natural fertilizer. A 2-in-1 deck covers both, while a 3-in-1 or 4-in-1 system adds side discharge or leaf shredding. For most small yards, 2-in-1 is plenty. Lawn keepers who deal with fall leaves or want fine mulching for healthier turf should look at Honda’s Versamow system with Clip Director on the HRX-BE and HRX-BV.
Key Considerations Across These Picks
Where Shoppers Go Wrong
The most common slip-up is buying a deck that’s too wide. A 21-inch deck on a yard with a 30-inch gate means dragging the mower through the side door, which scratches both. Measure gate openings before falling for a wider deck. The second mistake is underestimating runtime. A 20V battery covers a postage-stamp yard, but anything approaching a quarter acre on thick grass will demand a second battery or a higher-voltage platform. Finally, don’t skip cut height range. Models capped at 2.6 inches force a short cut that scalps uneven lawns and stresses grass in summer.
When Paying More Pays Off
The premium tier, like the Honda HRX-BE and HRX-BV, earns its place through cut quality and longevity. Twin-blade decks produce finer clippings, Versamow with Clip Director adjusts mulch-to-bag ratio on the fly, and Honda engineering typically outlasts budget platforms. Self-propelled drive on the HRX-BV is worth the upgrade only on slopes or larger lawns. For flat small yards, the cost rarely pays back. A brushless motor is the spec that quietly justifies mid-tier pricing for most shoppers, since it runs cooler, lasts longer, and sips battery more efficiently than brushed designs.
Frequently Asked Questions
How long does a cordless lawn mower battery last on a single charge?
Most 20V and 40V batteries in this roundup cover between 1/8 acre and 1/4 acre per charge, depending on grass thickness and cutting mode. Heavy or wet grass reduces runtime noticeably, while dry conditions and mulching mode tend to extend it.
Can cordless mowers handle thick or wet grass?
Brushless 40V models like the Worx WG735 and Wild Badger Power 40V 14-Inch Brushless Kit use torque management or high RPM to power through dense growth. Wet grass is tougher on any mower, cordless or gas, and tends to clog decks regardless of platform.
Are cordless mowers powerful enough for larger yards?
For lawns approaching a quarter acre, dual-battery 40V systems like the Worx WG745 handle the workload well. Anything beyond that range typically calls for a self-propelled gas or larger battery unit, since runtime and deck size start to compound the chore.
How do I maintain a cordless lawn mower?
Brushless motors require almost no maintenance. The main tasks are cleaning clippings from the deck after each mow, sharpening or replacing the blade once or twice a season, and storing the battery indoors during temperature extremes to extend cell life.
What is the difference between mulching and bagging modes?
Mulching chops clippings finely and drops them back into the lawn as a natural fertilizer. Bagging collects clippings in a rear bag for disposal, which keeps walkways cleaner and suits homeowners who prefer a tidy look or compost off-site.
Closing Remarks
The right compact cordless mower depends less on spec sheets than on the shape of your yard. Measure your gates, eyeball your grass type, and match the deck and battery platform to the lawn you actually mow, not the lawn you wish you had. Any of the eight picks here will handle small-yard duty well; the differences come down to deck width, battery ecosystem, and the cut-quality features that matter most to you.
