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
I've been using the EGO LM2135SP for two seasons now, and it's the closest thing to a gas mower I've found. The Select Cut feature lets me switch between bagging, mulching, and side discharge without tools, and the 7.5Ah battery consistently mows my entire half-acre on a single charge. The variable speed self-propel is intuitive-I can match it to my walking pace, even on slopes. I love that the cut is clean and even, with no clumping in damp grass. It's quiet enough to mow early Saturday without annoying the neighbors.
The 5 best Cordless Lawn Mowers of 2026, tested and ranked on real performance, build and value. Our top pick is the EGO Power+ Select Cut LM2135SP, with p...
I’ve spent years pushing mowers across real grass-my own half-acre, a few neighbors’ lawns, and even some rental properties I manage. When cordless electric mowers first appeared, I was skeptical: 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. I put together this list because I wanted to share which models actually deliver on their promises after hundreds of hours of real mowing-not just a quick test on a manicured strip.
What I 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. I also considered ease of adjustment, deck durability, and how well they handle uneven terrain. These are the mowers I’d recommend to a friend-or use myself.
How we test
I test each mower on the same three lawns: my own, which has a mix of fescue and Bermuda with some slopes and thick patches; my neighbor's flat, manicured lawn; and a rental property with neglected, often damp grass. I mow each lawn at least three times over several weeks, varying conditions like grass height and moisture. I measure cut quality by inspecting for stragglers, clumping, and scalp marks. I time battery run-to-empty with the mower on high speed and note how much area I cover. I also chat with owners who have used these mowers for a season or more to cross-check long-term reliability.
I do not accept paid placements or free mowers with strings attached. Every mower here I bought myself or borrowed from a friend. I have no affiliation with any brand. My goal is to give you honest, real-world insight from someone who actually uses these machines-not a scripted ad.

Ryobi 40V HP Brushless 21 inch
This Ryobi surprised me with its power. I mowed a neighbor's overgrown lawn that hadn't been cut in three weeks, and the brushless motor chewed through thick, wet grass without bogging down. The self-propel is smooth and has a good range of speeds. The 6Ah battery lasted about 45 minutes, which is enough for a quarter-acre. I appreciate the dual battery ports-you can run two batteries for extended runtime. The cut quality is good, though I noticed some stragglers on uneven ground. For the price, it's a solid performer.
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
I tested this Greenworks on my rental property's neglected lawn, and it handled the tall, weedy growth better than I expected. The 80V battery provides plenty of torque, and the 21-inch deck is wide enough to cover ground quickly. The self-propel is a bit jerky at low speeds, but once you get going, it's fine. I was able to mow the entire 0.3-acre lot on one 4Ah battery, with some charge left. The cut is decent, though it left a few clumps in damp grass. It's 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
I borrowed this Makita from a friend who swears by it, and after using it, I understand why. The dual 18V batteries give it impressive power-it cut through thick Bermuda without hesitation. The self-propel is one of the smoothest I've used, with a variable speed trigger that lets you dial in exactly the pace you want. The build quality is excellent; it feels solid and well-balanced. The only downside is the price and that you need two batteries, but if you're already in the Makita ecosystem, it's 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 workhorse. I used it on my own lawn during a stretch of rainy weather, and it mulched wet leaves and damp grass without clogging. The 80V battery lasts a long time-I mowed my entire half-acre and still had juice left. The self-propel is powerful but a bit aggressive; it took some getting used to. The cut quality is very good, with even results across the yard. For the price, it's a strong contender, especially if you want a mower that can handle tough 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
- 3-in-1 mulch, bag and side discharge
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.
