## What reviewers found

### 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](https://www.bobvila.com/reviews/best-robotic-mowers-2026/)
- 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.

### 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.

- 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.
