Fit snapshot
What to know before you buy
The strongest fit signals — and the things worth checking against your own lawn.
Check first
Potential limitations
- Requires a boundary wire, so it is a weaker fit if you want a fully wire-free installation.
- Its terrain rating is moderate, so very uneven or rough ground should be checked separately.
- Obstacle avoidance is rated basic, so gardens with many small or frequently changing objects deserve extra attention.
- Separated zones may require manually carrying the mower between areas.
