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.

Lawn fit analysis

How this mower fits different lawns

Verified technical data translated into practical fit signals for common lawn conditions.

Medium lawns

Recommended coverage is up to 850 m². Treat that as the capacity target, not a guarantee for every lawn layout.

Slope & terrain

The verified core data combines stated max slope 35%, 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, which matters most for multiple lawn areas or more complicated boundaries.

Trees & buildings

Boundary wire is paired with a very obstruction tolerant rating, which strengthens its fit for more complicated visibility conditions.
