Robot lawn mowers with perimeter wire keep your lawn tidy within a marked area. Thanks to the perimeter wire, the robot lawn mower knows where your garden begins and ends. It also moves around marked-off objects, such as trees or a shed. Place the perimeter wire around your lawn before you turn on your robot lawn mower. You can bury the perimeter wire or place them in the ground with pins. After this installation, the robot lawn mower does the work for you. That way, you can enjoy a tidy garden without much effort.
