I also appreciated that the Ryobi 40V platform is part of a larger battery ecosystem, so if I already own other Ryobi 40V tools, I can share batteries and save money.
Performance I Looked For
For me, the most important thing in a mower is whether it can handle real lawn conditions. I wanted something that could manage regular grass growth without bogging down. The HP brushless motor is designed to provide stronger performance, and that gave me confidence that it could handle thicker patches better than a basic entry-level electric mower. I also liked the idea of consistent power without the maintenance headaches of a gas engine.

Cutting Width and Lawn Size
The 20-inch deck is something I see as ideal for average residential lawns. It is wide enough to reduce mowing time, but still compact enough for me to maneuver around trees, flower beds, and tight corners. If my yard had lots of obstacles, I would appreciate this size even more because it feels easier to control than a larger mower.
Ease of Use
