What reviewers found
Segway Navimow X350
- PCWorld (TechHive): On a challenging, sloped yard it navigated well day and night and cut as well or better than the i and H series. AI mapping failed on the slope and the front end slid downhill when driving across a slope. Setup took about 30 minutes; recharges took 60 to 90 minutes. Source
- TechRadar: On a 1,000 m² (0.25 acre) lawn with large trees it mowed fast and neat, stayed accurate under trees and respected no mow zones. It avoided a ride on toy and a soccer ball but ran over a tangerine sized ball. Sub scores: design 5/5, performance 4.5/5, app 5/5, value 4/5. Source
Segway Navimow X450
- PCWorld (TechHive): Testing the X430 sibling, it climbed an uneven, sloped yard without spinning, sliding or stalling, stayed inside the boundary around trees and a play set, and did not slip over a raised edge where the i215 had. Editors' Choice; cons were price, size and weight. Source
- Expert Reviews: Testing the X4 series (X430 unit), it praised grip on 40° slopes, gravel and kerbs and easy setup. The first pass was very good, the second excellent, and it stayed 5 to 10 cm from beds. It ran about 150 min per charge and measured 68 dBA. Source
