What reviewers found
Lymow One
- Yanko Design: Tested on a yard with 32 oak trees. About one hour from unboxing to first mow, mapped 6,778 sq ft, and a full mow took about 178 to 185 minutes. It climbed a 6 in stump, threw a track on a 6 in curb and recovered, and stopped quickly for a foot in its path. Cut matched a walk behind mower on St. Augustine grass. Source
- Freshly Charged: One week of backyard testing on a pre production unit. Cleared 2 in obstacles and small steps, never got stuck and left clean stripes in long grass. Noticeably louder than rivals (68 dB on the spec sheet) and hard to move at 77.6 lb. Source
Segway Navimow X430
- Bob Vila: Named Best Overall. Handled thick St. Augustine grass and steep side yards better than the other six mowers tested; mapping was the easiest in the group; the RTK antenna was never needed. Source
- PCWorld (TechHive): Editors' Choice. On a 7,600 sq ft test lawn it stayed inside boundaries, climbed slopes without slipping and did not go over a raised edge that a smaller Navimow fell into; cut was even at 3 and 4 in. Source
