Segway Navimow X350
Fast RTK and vision mower for big, open lawns up to 1.5 acres
Researched by Riley Hart · updated Oct 30, 2026
Is the Segway Navimow X350 worth it? The X350 is built for large, mostly open lawns where speed matters, and both PCWorld and TechRadar praised its navigation, even under trees. It costs $2,799 as of Oct 30, 2026, and 2 independent reviewers tested it.
The X350 is built for large, mostly open lawns where speed matters, and both PCWorld and TechRadar praised its navigation, even under trees. It is two wheel drive, so very bumpy ground or steep side slopes are not its strength. Owners of small or hilly yards should look at an AWD model instead.
Best for: big open lawns up to 1.5 acres. Skip if: your yard is small or has steep side slopes.

What independent reviewers found
- 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.
- PCWorld (TechHive)
- 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.

Questions buyers ask
Do I need to install the RTK antenna?
Not if your address has Network RTK coverage, which Navimow checks by postcode. Otherwise you install the included antenna.
Is there a cellular fee?
The X350 includes 3 years of 4G service at no cost, per Navimow. Terms after year 3 are not listed.
Can it handle hills?
Navimow rates it for 50% slopes. PCWorld found it climbs straight up well but slides when it drives across a slope, since it is not AWD.
