Yes. In order for Robomow to operate in your lawn, a Perimeter Wire must be installed around the entire lawn, and around protected areas within the lawn area. Proper installation of the Perimeter Wire is critical for the quality and reliability of Robomow’s operation. You can hire a professional installation service (recommended) or do the installation yourself. For more information about professional installation services, please refer to the Robomow website at www.robomow.com.
