Cutting along tiles
If the tile area is flat and in level with the lawn, you can let the robot drive a little out into
the tile area with one wheel and thereby cutting over the edge of the lawn. Lay here the
boundary wire with 8 cm distance to the edge.
Uneven lawn surface
If the lawn has an uneven surface, there will be risk of damaging the blades, as they risk
hitting the ground. This should be avoided to ensure the durability of the robot mower.
Level the cutting area, fill holes with soil. If it is not possible to level the surface, this area
should be excluded from the cutting area with a boundary wire.
