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.
- Passages should be at least about 57 cm wide according to the specification.
- 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.
Lawn fit analysis
How this mower fits different lawns
Verified technical data translated into practical fit signals for common lawn conditions.
01
Compact lawns
Recommended coverage is up to 150 m². Treat that as the capacity target, not a guarantee for every lawn layout.
02
Slope & terrain
The verified core data combines stated max slope 15%, moderate terrain rating. That makes slope and terrain an important part of this mower’s fit profile.
03
Trees & buildings
Boundary wire is paired with a very obstruction tolerant rating, which strengthens its fit for more complicated visibility conditions.
