🛒 Buying Guide: What to Look For
Battery Voltage & Runtime
Higher voltage generally means more power. Look for 40V minimum for small yards, 56V-80V for medium to large yards. Runtime typically ranges from 30-60 minutes per charge—make sure it's enough for your lawn.
Deck Size
Wider decks (20-21") cover more ground per pass but are heavier. Smaller decks (17-19") are more maneuverable and better for tight spaces.
Self-Propelled vs Push
Self-propelled models are worth the extra cost if you have hills or a large yard. Push mowers are lighter and cheaper but require more effort.
Mulching, Bagging, or Side Discharge
Most modern mowers offer all three options. Mulching returns nutrients to your lawn, bagging keeps things tidy, and side discharge is fastest.
Battery Ecosystem
If you already own cordless outdoor tools, consider sticking with the same brand to share batteries. EGO, Greenworks, and Ryobi all have extensive ecosystems.
❓ Frequently Asked Questions
Are cordless mowers as powerful as gas mowers?
Yes! Modern brushless motors in 56V-80V mowers match or exceed the power of most residential gas mowers. Professional-grade gas mowers still have an edge for very thick grass or commercial use.
How long do cordless mower batteries last?
Most batteries last 30-60 minutes per charge, enough for 1/4 to 1/2 acre. Battery lifespan is typically 3-5 years or 500+ charge cycles.
Can I use my cordless mower on wet grass?
It's not recommended. Wet grass clumps more, can clog the deck, and makes the mower work harder. Wait until grass is dry for best results.
Are cordless mowers worth the higher upfront cost?
Yes, in the long run. No gas, oil changes, spark plugs, or carb maintenance. Lower noise, zero emissions, and instant starting. Most owners save $50-100/year on maintenance.
🎯 The Verdict
For most homeowners, the EGO Power+ LM2135SP is our top recommendation. It offers the best balance of power, runtime, and features. Budget-conscious buyers should consider the Ryobi 40V HP—it's 30% cheaper while still delivering excellent performance.
