ROBOMOW RX20 Pro - Rule #4: - 5

Lay the wire

Lay the Perimeter Wire (“virtual boundary”), which defines the working area for the mower.

ROBOMOW RX20 Pro - Lay the wire - 1

  • Have mower's package nearby.
  • Before you start wiring, use your old mower to cut your grass to the height no more than 6 cm (2.5") one last time. This will make inserting pegs easier and help ensure the mower doesn't cut the wire.

SLOPES

Slopes along the edge

To ensure your mower doesn't slip off the lawn, especially when the grass is wet, the Perimeter Wire must exclude a slope along the edge of your lawn with an incline of over 10% - that is, 10 cm rise per 1 m [4 in rise per 3 ft].

Less than 10% More than 10%

D. Protect obstacles

Hard obstacles

Obstacles that are vertical, rigid and higher than 15 cm (6 in), such as trees or telephone poles, do not need to be protected by the Perimeter Wire. The mower will bump into them and turn away.

Soft obstacles

Objects such as flower beds, ponds, or small trees must be protected by setting Perimeter Islands.
