## Verdict

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.

- Covers up to 1.5 acres
- Up to 200 min runtime with 80 min recharge
- Accurate RTK and vision navigation, even under trees
- 3 years of 4G included
- IP66, hose washable

## Cons

- Two wheel drive, can slide across slopes
- Large, hard to fit through narrow gates
- No onboard rain sensor
- Expensive

## 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.
