EGO Power+ LM2135SP -- Best Overall Electric Lawn Mower
The EGO LM2135SP is the standard by which other cordless mowers are judged. The 56V arc lithium battery delivers up to 60 minutes of run time, and the self-propelled rear-wheel drive adjusts to your walking pace with a thumb lever. The 21-inch steel deck cuts cleanly through damp grass without clogging.
Greenworks Pro 80V 21" -- Best for Medium Yards
The Greenworks Pro 80V brings higher voltage to a competitive price point, giving it noticeably more torque on thick patches of grass. The brushless motor and 21-inch steel deck handle up to a half acre per charge on flatter terrain. Mulching, bagging, and side-discharge are all supported with the included attachments.
Ryobi 40V HP 20" -- Best Budget Electric Mower
The Ryobi 40V HP 20-inch mower brings solid performance to budgets. The brushless motor provides more power and longer motor life compared to brushed alternatives in this price tier. A 40V battery is enough for lawns up to a quarter acre, and the 20-inch deck keeps the weight manageable at around 50 pounds.
Husqvarna Automower 450X -- Best Robotic Electric Mower
The Husqvarna Automower 450X is for homeowners who want to eliminate mowing time entirely. The robotic mower navigates up to 1.25 acres using a boundary wire system, works in rain, and returns automatically to its base to recharge. Mowing frequency is programmed via a smartphone app or the built-in display.
Kobalt 80V 21" -- Best Mulching Electric Mower
The Kobalt 80V 21-inch mower earns its spot on the strength of its mulching performance. The dual-blade mulching system chops clippings into fine pieces that decompose quickly and return nutrients to the lawn. The 21-inch deck and 80V brushless motor handle medium yards with ease, and run time on the included 5Ah battery reaches 50 minutes on level ground.
Before you buy
What to consider
Yard size is the first filter. For lawns under a quarter acre, a 40V push mower is sufficient. Half-acre properties call for 60V or 80V and ideally a self-propelled drive. Beyond that, a robotic mower or dual-battery system makes the most sense. Voltage alone does not determine performance, the battery amp-hour (Ah) rating matters equally for run time.
What to consider
Consider terrain as well. Sloped yards benefit from self-propelled rear-wheel drive. Flat yards can get by with push models at lower cost. Mulching is better for lawn health than bagging unless you are dealing with excessive clippings. Match the deck width to the yard: wider decks cover more ground per pass but are harder to maneuver around trees and garden beds.

Quick answers
Most 40V to 60V battery packs provide 30 to 60 minutes of run time on a single charge, which covers roughly a quarter acre to a half acre of flat lawn. Higher-voltage systems and mowers with larger Ah battery packs run longer. Some models support dual batteries for extended run time on larger properties.
Yes, but performance varies by motor power. Models with brushless motors rated at 60V or higher handle thick, overgrown grass well. If your lawn tends to grow tall between mowings, choose a mower with a high-torque brushless motor and deck heights of at least 3.5 inches to tackle taller growth without bogging down.
