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.
