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
Sunseeker X7 Gen 2
- Yanko Design: One week on a 6,777 sq ft Texas lawn with 32 oaks and an embankment. RTK fixed within a couple of minutes, the map held all week, it cut damp St. Augustine evenly, avoided a hose at night and fit through a 28 in gap. Source
- Homecrux: Hands on with five Sunseeker mowers sent by the company. The X7 ran at night, avoided obstacles reliably and left minimal missed spots; the article calls it the X7 Plus Gen 2 in one place and gives no measurements. Source
