## Verdict

The X315 brings the fast X3 platform to half acre lawns, and two independent testers found its navigation and obstacle detection reliable. Without the add on trimmer it leaves an uncut strip along edges, and Notebookcheck's unit could not reliably climb its rated 50% slope. Skip it for very small lawns, where cheaper i series mowers do the job.

## Pros

- Fast, systematic lane mowing
- Reliable obstacle detection in two tests
- Quick 1 hour recharge
- Large onboard display
- Network RTK often avoids an antenna install

## Cons

- Leaves an uncut edge strip without the trimmer
- Rated slope not reached in Notebookcheck's ramp test
- High energy use for a mower this size
- Store page shows two different prices

## Questions buyers ask

### How much does the X315 cost?

Navimow's US page showed $1,999 in its model picker and $2,299 in the header on 2026-10-30. Its 2025 launch price was $2,299.

### Does it cut right to the edge?

No. Notebookcheck measured at least 10 cm left uncut along edges. Navimow sells an Expansion Bay edge trimmer for the X3 series.

### Is the X315 worth it for a tiny lawn?

PC-Welt tested it on 120 m² and said its potential is wasted on a lawn that small.
