Dana Whitlock

Dana writes about the mowers themselves. How each one works out where it is, whether that is satellites, a camera or a wire in the ground. What a brand's slope number or lawn-size number is really measuring, and where it will flatter the machine. And which of two mowers comes out ahead when you put them side by side. She reads the handbooks so you do not have to, and she says so plainly when a brand leaves a number out. Dana is a pen name, and she is not an engineer.

How we rank and review

Reviews

Maps by laser and camera. It needs no wire and no satellite antenna. 4.3/5 ECOVACS GOAT A3000 LiDAR PRO review: a big yard, even under trees Dana Whitlock Sep 2026 It maps your lawn with a laser and a camera instead of satellites, so tree cover doesn't stop it. It cuts up to about three-quarters of an acre. The edging trimmer is loud. Finds the lawn by satellite. It needs no buried wire. 4.2/5 ECOVACS GOAT A2500 RTK review: half an acre, and no wire to bury Dana Whitlock Sep 2026 It uses satellites to learn where your lawn ends, and a sensor to spot things in its path. It cuts twice as much grass as most cheap mowers at this price. But it only works with plenty of open sky above the lawn.

Head to head

i215 LiDAR vs LUBA mini 2 Navimow i215 LiDAR vs LUBA mini 2 AWD: which one climbs a steeper lawn? Dana Whitlock Nov 2026 Both use a laser to find their way, so both keep working under trees. Both are rated for the same size of lawn. Where they differ is how steep a hill each one can climb. A2500 RTK vs LUBA 3 ECOVACS GOAT A2500 RTK vs Mammotion LUBA 3 AWD: which one is better in shade and on slopes? Dana Whitlock Sep 2026 Two mowers that need no buried wire around the lawn. The A2500 needs a clear view of the sky. The LUBA 3 keeps working under trees, and it climbs much steeper ground.

Guides

How they work Wire-free robot mowers need a clear view of the sky. Here is how to check yours. Dana Whitlock Sep 2026 Wire-free mowers let you draw the lawn in an app instead of laying a cable. Before you buy one, go outside and check how much open sky is above your lawn. Trees and roofs over the grass stop these mowers working.
