ROB uses boundary wire as a guide, indicating the areas which it should work within. The boundary wire should be installed around the edge of your lawn, and around any large objects like trees and hedges. The boundary wire can be installed in the following ways:
Secure the wire to the ground with pegs - It is recommended that you peg down the boundary wire if you want to make adjustments during the first few weeks of using the robotic lawnmower. A hammer or plastic mallet can be used to secure the pegs that are supplied with ROB. After a few weeks, the grass will have grown over the wire making it no longer visible.
Bury the wire - If you dethatch or aerate your lawn it is recommended that you bury the boundary wire to avoid damage. The boundary should be at least 1cm into the ground and at a maximum of 20cm.
