Fit snapshot

What to know before you buy

Check first

Potential limitations

Requires a boundary wire, so it is a weaker fit if you want a fully wire-free installation.
Navigation is rated for some obstructions rather than heavy obstruction, so dense tree or building cover deserves a fit check.
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.

Compact lawns

Recommended coverage is up to 400 m². Treat that as the capacity target, not a guarantee for every lawn layout.

Slope & terrain

The verified core data combines stated max slope 30%, moderate terrain rating. That makes slope and terrain an important part of this mower’s fit profile.

Complex gardens

The specification lists multi-zone support for up to 4 zones, which matters most for multiple lawn areas or more complicated boundaries.

Trees & buildings

Boundary wire is rated for some obstructions. Heavy tree or building cover remains a sensible condition to verify.
