A small patch of grass shouldn’t mean wrestling with extension cords, hunting for outlets, or dragging out a mower built for a half-acre. Compact cordless lawn mowers solve a simple problem: tidy, weeknight-friendly mowing for tight lots, narrow side yards, and townhouse strips where storage space is measured in square feet, not feet. Battery power has caught up to small-yard demands, brushless motors stretch runtime, and folding handles let the whole thing disappear into a garage corner. This roundup breaks down five solid options covering the spread from ultralight push mowers to battery-driven workhorses with full mulching kits, so you can match the mower to the lawn rather than the other way around.
The Choices Worth Comparing
MZK 20V 13-Inch Electric Lawn Mower (Red)
Worx 20V 14-Inch Cordless Lawn Mower WG733.1
Honda HRX-BE 21-Inch Battery Mower (HRX217YXBEXA6)
Honda HRX-BV 21-Inch Battery Mower (HRX217YXBVKA4)
BLACK+DECKER 20-Inch Corded Electric Mower BEMW213
A Breakdown Of The Leading Choices
The MZK 13-inch walks in as one of the narrowest mowers in this lineup, and for small-lot owners that footprint is the whole pitch. A brushless motor (a design with no carbon brushes, which means less friction and longer motor life) drives the deck, with a low-speed setting around 2800 RPM and a high setting near 3400 RPM, giving the user enough headroom to push through thicker patches without bogging down. The body is short enough to slide past a narrow side gate and light enough that carrying it down a basement stair is not a workout.
Where this unit feels at home is a townhouse lawn or a narrow strip out back, especially the kind that ends with a flower bed in one corner and a fence post in the other. The cutting deck covers less ground per pass than the 20-inch picks later on, which means more laps, but the trade-off shows up in storage: a closet, a shed corner, even behind a dryer vent. Most owners find the 1.3 to 2.6-inch height range covers the seasonal swing between early-spring scalps and mid-summer length.
Advantages To Know
- Brushless motor extends runtime and trims long-term wear compared with brushed designs.
- Four height settings between 1.3 and 2.6 inches cover most seasonal mowing preferences without fuss.
- 13-inch deck slips through standard side gates, a real plus in older neighborhoods.
- Lightweight frame is easy to lift into a trunk or carry up a stoop for weekend cuts.
Things To Consider
- The smaller deck means more passes on any lawn past about 1,500 square feet.
- Battery life depends heavily on grass length and the chosen speed setting, so overgrown yards may chew through a charge quickly.
Key Specs
Whose Yard It Belongs On
Small-lot owners, townhouse residents, and anyone who values a mower they can park in a closet rather than a shed.
Look Elsewhere When
The BLACK+DECKER BEMW213 is a better fit if you have a flat lot under 1,500 square feet and prefer the no-fuss simplicity of a corded model with no battery to manage.
Worx built the WG733.1 as the lightest, smallest mower in its own catalog, and that framing matters: a brand that makes a dozen other outdoor tools did not design this as a scaled-down flagship, it designed it as a city-yard specialist. A brushless motor keeps the package efficient, and a single 20V 5.0 Ah PowerShare Pro battery pushes the mower through lawns up to roughly 3,200 square feet before needing a swap. The 2-in-1 deck switches between bagging and rear discharge, which keeps options open without bolting on extra attachments.
For apartment renters with a small patch behind the building, or a homeowner whose entire yard is a 12-by-20 rectangle, the WG733.1 makes mowing feel less like a chore and more like a quick weekend errand. Compared with the MZK 13-inch above, this unit trades a touch of narrowness for more battery capacity and a longer single-charge range, though in our view the difference is more about yard size than cut quality. Storage is where it really earns its keep: the handle folds and the whole unit tucks into a closet corner or even a large utility shelf.
Practical Pluses
- Single 5.0 Ah PowerShare Pro battery covers lawns up to 3,200 square feet on a charge, enough for many small city lots in one go.
- Ultralight build and folding handle make it the easiest mower here to store and transport.
- Battery platform is shared across the broader Worx 20V tool family, so existing tool owners save on extra packs.
- 2-in-1 deck supports bagging or rear discharge without extra attachments.
Worth Noting
- 14-inch deck still leaves larger yards feeling like a long walk; you will feel every extra pass.
- No mulching mode out of the box, so clippings get bagged or discharged, which may matter for lawn-care purists.
Made For
Apartment dwellers, small-lot homeowners, and Worx tool owners who want one battery platform across the shed.
Swap It Out When
The Honda HRX-BE is a stronger fit if mulching and cut quality matter more than weight, and you have a slightly larger lot to maintain.
Honda’s HRX-BE is a different class of machine than the two smaller picks above, a battery walk-behind that aims to match the torque and cut quality the brand built its reputation on with gas engines. The 21-inch deck covers ground fast, and the standout feature is the Versamow system with Clip Director, a sliding lever that lets you switch between bagging, mulching, side discharge, and leaf-shredding without swapping any attachments. Twin blade setup (two stacked cutting blades rather than one) handles thicker, taller grass without the deck stalling out mid-row.
You reach for the HRX-BE when the lawn is bigger than a patch and you still want battery convenience. The trade-off is size and weight: this is a full-size push mower with a full-size footprint, and it will not fold into a closet. For a suburban yard where cut quality and mulching flexibility matter as much as quiet operation, though, this is the unit that feels the most grown-up of the cordless bunch. The 21-inch deck also slashes mowing time on lots that would have the MZK and Worx running two extra passes per row.
Real Benefits
- Versamow system with Clip Director allows bagging, mulching, discharging, and leaf-shredding in one deck, no tools required.
- 21-inch cutting width covers ground quickly, making the mower practical for lots up to roughly half an acre.
- Twin blade design sustains cut quality in taller, thicker grass without bogging down.
- Battery platform removes gas-engine maintenance like oil changes and spark plugs.
Honest Caveats
- Full-size footprint needs real storage space, not a closet corner.
- Heavier than the MZK and Worx, so pushing it up slopes can be a workout, and the unit is not self-propelled.
- Higher upfront cost than entry-level cordless mowers, which may not fit tighter lawn-care budgets.

Reach For A Different Pick When
The Worx WG733.1 is a better fit for city dwellers with a small patch who care more about storage and weight than 21-inch coverage.
The HRX-BV takes the HRX-BE’s deck and adds a self-propelled drive system, which is the difference between walking the mower and walking with the mower. Variable speed control lets you match the pace to the terrain: slow on a slope, faster on a flat stretch, easier on the knees when the bag starts to fill. Underneath, you get the same Versamow Clip Director setup and twin-blade deck as the HRX-BE, so cut quality and mulching flexibility carry over from the previous pick.
This is the Honda to reach for if your yard has a grade to it, a corner you have to muscle through, or a section where walking speed varies from row to row. The same caveats that apply to the HRX-BE carry over here: the footprint is full-size, the storage ask is real, and the price tag climbs with the added drive system. In our view, the BV earns its place for sloped or uneven lots where a push mower starts to feel like a workout, but it is overkill for a flat city strip where the MZK or Worx would do the job in less time and less closet space.
The Practical Payoff
- Self-propelled drive reduces fatigue on sloped or uneven yards.
- Variable speed control lets you tune pace to the terrain, faster on flats, slower on climbs.
- 21-inch Versamow deck with Clip Director offers the same tool-free mode switching as the HRX-BE.
Points To Keep In Mind
- Heavier and bulkier than the non-propelled HRX-BE, so storage needs more room.
- Premium price tier, which may not pencil out for flat, small-lot owners.
- Battery and drive system add complexity, and the unit is heavier to push if the drive is ever disengaged.
Built With In Mind
Homeowners with sloped, uneven, or longer yards who want battery convenience without giving up the muscle of a self-propelled drive.
Where Another Pick Suits Better
The MZK 20V 13-Inch Electric Lawn Mower is a smarter fit for flat townhouse lawns where a self-propelled drive is unnecessary and a smaller deck handles the space in fewer storage headaches.
The BEMW213 is the one corded entry in a list full of battery mowers, and the trade-off is straightforward: you trade runtime freedom for unlimited power. A 13-amp motor drives a 20-inch deck with a winged blade (a blade shape designed to lift grass upright before cutting, which improves collection) that pulls clippings into the rear bag, and a push-button start removes the pull-cord dance. Six height settings between 1.5 and 4 inches give the widest adjustment range in this roundup, useful for spring scalps and tall summer cuts alike.
For homeowners with a flat, small yard and an outdoor outlet within 50 feet, the BEMW213 keeps the budget honest and removes any worry about battery degradation. The catch shows up the moment you want to mow past the cord’s reach, or when the nearest outlet sits on the far side of the driveway. Assuming a standard extension cord in good shape, this mower delivers consistent power from start to finish, no runtime anxiety, no battery aging. Compared with the MZK and Worx above, it gives up cordless convenience for a wider deck, more height settings, and a price that tends to land lower than its battery-driven siblings.
What It Does Well
- 20-inch deck covers more ground per pass than the 13- and 14-inch cordless picks, cutting mowing time on small lots.
- Six height settings between 1.5 and 4 inches offer the broadest range in this lineup.
- No battery to charge, replace, or store over winter, which simplifies ownership.
- Push-button start is easier on the wrist than a pull cord.
Practical Considerations
- Corded design limits range to the nearest outdoor outlet and requires cord management while mowing.
- Not suitable for lawns that extend well beyond a 50-foot reach from a power source.

Budget-focused homeowners with a flat, small yard and easy access to an outdoor outlet who want to skip battery upkeep.
Not Your Match When
The Honda HRX-BV is a stronger fit for sloped or uneven lots where a self-propelled drive and 21-inch deck make mowing easier on the body.
What To Weigh Before Choosing A Cordless Mower
Deck Size And Yard Footprint
Cutting width sounds like a number, but in practice it shapes how a mowing day feels. A 13-inch deck on the MZK is forgiving in narrow gates and tight turns, while a 21-inch deck on the Honda HRX pair covers ground faster but demands wider turning room. For lawns under 1,500 square feet, a smaller deck is often the smarter move, since you are not really saving time by going wider. Above that, the wider decks start paying for themselves in fewer passes and shorter mow days.
Battery Runtime And Voltage
Voltage and amp-hours together tell you how long a mower will last on a charge. A 20V 5.0 Ah pack like the one in the Worx WG733.1 gives more runtime than a smaller pack, though actual results depend on grass length, terrain, and which speed setting you run. The honest read is that you should treat manufacturer runtime claims as the best-case scenario: thick, wet grass drains batteries faster than the brochure suggests. Matching battery capacity to lawn size is more useful than chasing the highest voltage on the shelf.
Mulching, Bagging, And Discharge Modes
A 2-in-1 deck like the one on the Worx keeps things simple. A 4-in-1 system with Versamow, like on the Honda HRX pair, adds real flexibility for homeowners who want to mulch in summer, bag in spring, and shred leaves in fall without swapping attachments. Decide what you actually do with clippings, and pick the deck that matches, since the extra versatility often comes with a price step up.
Storage And Footprint
Compact cordless mowers earn their keep on the storage side, and there is real variation here. The MZK and Worx both fold down small enough to live in a closet. The Honda HRX pair, while still smaller than a riding mower, ask for a proper shed corner. Buyers in apartments or townhomes with no garage should weigh the folded footprint as carefully as the cutting width, because the mower has to live somewhere between mowings.
Common Shopping Slip Ups And Where The Extra Money Goes
Pitfalls Shoppers Hit
A common slip is matching the mower to the brochure, not the yard. A 21-inch deck on a 600-square-foot strip means a lot of extra weight for no real time savings, while a 13-inch deck on a quarter-acre turns a 20-minute mow into an hour. Another trap is underestimating corded-vs-cordless trade-offs: a corded mower like the BEMW213 looks simpler, but the moment you have to mow around a detached garage or wrap a cord around a tree, the convenience gap widens. Buyers also often overlook storage dimensions, only to find the mower does not fit where they planned to keep it.
What The Higher Tier Buys
Stepping up from a compact 13- or 14-inch cordless mower to a 21-inch Honda HRX buys three things: a wider deck, the Versamow mulching system, and twin-blade cut quality. The wider deck alone can halve mowing time on mid-size lots, and the Versamow Clip Director turns the deck into a four-mode tool without extra attachments. The self-propelled HRX-BV adds variable-speed drive on top of that, which is the difference between pushing and walking on sloped ground. For flat, small yards, the premium tier is overkill. For lots with slope, varied grass length, and a desire for clean mulched clippings, the upgrade is hard to argue with.
Frequently Asked Questions
How long does a compact cordless lawn mower battery typically last?
Most 20V packs in this size class run 25 to 40 minutes on a single charge, depending on grass length, speed setting, and terrain. Light, dry grass on a low setting extends that range, while thick or wet grass shortens it noticeably.
Can cordless mowers handle wet grass?
Lightly damp grass is workable for most brushless cordless mowers, though cut quality and bagging performance both drop. Heavy, soaked grass strains the motor and drains the battery fast, so waiting for a drier day is the better call whenever possible.
Are cordless mowers powerful enough for thick or tall grass?
Brushless designs like the MZK and Worx units hold up well in moderate growth, especially on a high-speed setting. For consistently tall or thick grass, a 21-inch Honda HRX with twin blades and higher torque is the safer bet in this roundup.
How loud are compact cordless mowers compared with gas models?
Cordless mowers run significantly quieter, typically in the 75 to 85 dB range, which is closer to a household vacuum than a gas engine. That makes them friendlier in close-set neighborhoods and lighter on ear protection for short sessions.
Do cordless mower batteries need special winter storage?
Lithium-ion packs last longest when stored at partial charge in a cool, dry place, ideally between 40 and 70 degrees. Leaving a battery fully drained in an uninsulated shed through winter is the most common cause of permanent capacity loss.
The Takeaway
A small yard does not mean a small decision. The MZK and Worx cover tight-lot and storage-first situations, the BLACK+DECKER keeps things simple for anyone close to an outlet, and the two Honda HRX models step up for bigger or sloped lawns where cut quality and drive power matter. Match the deck to the lawn, the battery to the size, and the footprint to the storage spot you actually have. The right mower is the one that makes next Saturday’s mow feel like a quick errand, not a project.
