Formula result: 7.9/10

Compare the stated lawn capacity with your own measured lawn, and the stated slope rating with your steepest section. Wire-free navigation still needs a clear sky view or a stated alternative, and every robot mower needs supervision around children, pets and edges. Confirm the exact model, included base station and current app requirements in the manufacturer manual.
