Perimeter switch turned 
on to generate signal 
Virtual wall, visible 
only to the 
Robomower. 
A small wire, called the perimeter wire, is placed around the perimeter of the lawn and any other areas 
where you do not want the mower to enter. A small signal is generated from a device attached to the 
perimeter wire, called the Perimeter Switch. When turned on, this signal is carried through the perimeter 
wire, creating what we define as a virtual wall. The virtual wall is visible only to the Robomower, keeping 
the Robomower where you want it, on your lawn. The perimeter switch must be turned on to activate the 
perimeter wire before the Robomower will operate.
