## What reviewers found

### Segway Navimow X330

- TechRadar: Tested the X350, a larger battery sibling in the same X3 series. It mowed fast and stayed accurate under trees, but missed a very small ball and may struggle on rough terrain with 2WD.

### 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.
