Quick verdict
The EGO Power+ Select Cut LM2135SP is the best overall cordless mower for its superior cut quality and runtime, while the Ryobi 40V HP Brushless offers the best value for budget-conscious buyers.
EGO Power+ Select Cut LM2135SP
The EGO LM2135SP is often cited as one of the closest cordless mowers to gas performance. Its Select Cut system switches between bagging, mulching, and side discharge without tools, and the 7.5Ah battery is rated to mow roughly a half-acre on a single charge. The variable-speed self-propel can be matched to your walking pace, even on slopes, and owners consistently report a clean, even cut with little clumping in damp grass. It also runs quietly enough for early-morning mowing.

Ryobi 40V HP Brushless 21 inch
This Ryobi is a strong performer for the price. The brushless motor powers through thick, wet, or overgrown grass without bogging down, and the self-propel offers a smooth, wide speed range. A 6Ah battery delivers roughly 45 minutes of runtime, enough for about a quarter-acre, and dual battery ports let you run two packs for extended sessions. Cut quality is good overall, though some stragglers can appear on uneven ground.
Reasons to buy
- Great value for the price
- Quiet and efficient brushless motor
- Compatible with Ryobi 40V batteries
Reasons to avoid
- Battery runtime shorter than premium models
- Plastic deck feels less durable
- 40V HP brushless · 21 in deck · self-propelled
- Cross-compatible with the Ryobi 40V tool battery range
Greenworks Pro 80V 21 inch
The Greenworks Pro 80V handles tall, weedy, or neglected growth better than many cordless mowers thanks to the torque of its 80V system, and the 21-inch deck covers ground quickly. The self-propel can feel jerky at low speeds but smooths out at pace. A single 4Ah battery is generally enough for a 0.3-acre lot, and while it may leave a few clumps in damp grass, it is a good value for larger yards.
Reasons to buy
- Powerful 80V system handles thick grass
- Brushless motor with high torque
- Large 5Ah battery included
Reasons to avoid
- Heavier than some competitors
- Battery not compatible with lower voltage Greenworks tools

Makita 18Vx2 LXT 21 inch
The Makita 18Vx2 draws on dual 18V batteries for impressive power, cutting through thick Bermuda without hesitation. Its self-propel is among the smoothest available, with a variable-speed trigger for precise pace control, and build quality is excellent, solid and well-balanced. The main trade-offs are the price and the need for two batteries, but for anyone already in the Makita ecosystem it is a top choice.
Reasons to buy
- Compatible with Makita 18V LXT batteries
- Steel deck for durability
- Consistent cut quality
Reasons to avoid
- Requires two batteries (not included with some kits)
- Heavier than many competitors
- Runs on two 18V LXT batteries · 21 in deck
- Quiet brushless drive · folds flat for storage
Kobalt 80V 21 inch
The Kobalt 80V is a capable workhorse in tough conditions, mulching wet leaves and damp grass without clogging. The 80V battery offers long runtime, enough for a half-acre with charge to spare, and cut quality is very even across the yard. The self-propel is powerful and can feel aggressive at first. For the price, it is a strong contender for demanding conditions.
Reasons to buy
- Low price for an 80V mower
- Good power for most lawns
- Quiet operation
Reasons to avoid
- Plastic deck feels less sturdy
- Battery life declines over time
- 80V brushless · 21 in steel deck · self-propelled

Our team has spent years researching how mowers perform on real grass—from half-acre suburban lots to uneven rental properties. When cordless electric mowers first appeared, early owner feedback indicated they felt underpowered and ran out of juice halfway through a decent-sized yard. But over the past few seasons, the technology has genuinely matured. Now, some of these machines rival gas mowers in cut quality and run time, while being quieter and almost maintenance-free. We put together this list because we wanted to share which models actually deliver on their promises based on extensive research and owner reports—not just a quick test on a manicured strip.
What we looked for: reliable power to cut thick, damp grass without bogging down; battery life that can handle a typical suburban lawn on one charge; a clean, even cut that doesn’t leave streaks or clumps; and ergonomics that don’t leave your hands numb after 45 minutes. We also considered ease of adjustment, deck durability, and how well they handle uneven terrain. These are the mowers we’d recommend to a friend—or use ourselves based on our research.
How we research
This guide is built on structured research rather than in-depth research of every product. We compare each model against the manufacturer's published specifications and manual, cross-check verified owner feedback for real-world reliability and performance, and weigh each pick against the strongest alternatives in its category. Where a recommendation reflects first-hand experience with a tool, we say so. See our full research method.
What to look for
Deck size
21 to 22 inches suits most yards; go smaller for tight gardens, larger for open lawns.
Battery and runtime
Higher voltage means more power, higher amp-hours mean longer runtime. Roughly 4Ah at 40V or 2.5Ah at 80V covers a quarter-acre.
Self-propelled
Worth it on slopes or larger lawns; skip it on small flat yards to save weight and money.
Brushless motor
Quieter, cooler and longer lasting. Nearly every modern cordless mower uses one, so avoid older brushed models.
Mulch, bag, discharge
A 3-in-1 deck gives the most flexibility season to season.
Our verdict
The EGO Power+ Select Cut LM2135SP is the best overall cordless mower for its superior cut quality and runtime, while the Ryobi 40V HP Brushless offers the best value for budget-conscious buyers.
FAQs
Runtime varies by battery capacity and grass conditions. Typical runtimes range from 30 to 60 minutes. For a 0.25-acre lawn, a 5Ah battery at 40V usually suffices. Larger lawns may need spare batteries.
Yes, many brands share batteries across their tool line. EGO uses 56V, Ryobi 40V, Greenworks 80V, Makita 18V, and Kobalt 80V. Check compatibility before buying.
Modern cordless mowers with brushless motors and high voltage (56V+) match gas mowers in cutting power for most residential lawns. They lack the top-end torque for extremely thick, wet grass but are quieter and require less maintenance.
Charging time depends on the charger and battery size. Standard chargers take 60-120 minutes for a full charge. Fast chargers can do it in 30-45 minutes. Some mowers have a second battery slot for extended use.
