RoboMower requires a one time simple set-up, which can be easily done by anyone. A wire is laid around the outer edges of the lawn, and attached to the surface of the lawn with pegs every few meters. The wire and pegs are supplied with the RoboMower. The wire is connected to a small battery powered current source called Perimeter Switch (also supplied in the box). Typically the wire will be covered by grass and become unnoticeable in a matter of 2-3 weeks. RoboMower recognizes the wire using a special sensor, and makes sure it always stays inside the designated area.

RoboMower is operated automatically by programming the unit to automatically begin mowing at the day and time that you select! Or you can manually start the robomower by pressing the green "Go" button on the unit. It travels on the lawn in a systematic criss-cross pattern covering the lawn several times from side to side to ensure that the entire yard is covered and the grass is cut from several angles.

How does it cut the grass?
It features a battery powered three blade, 21" (53 cm) powerful cutting system equivalent to a 5.5 HP gas mower. RoboMower is a dedicated mulching mower that mulches better than a traditional mower thanks to its Triple-Chamber-Mulching system and the 5800-RPM blade speed, double that of a typical gas mower. Grass is cut into very small clippings that are buried in the roots of the lawn, where they decompose and act like a natural fertilizer. This results in a healthier and better-looking lawn, and eliminates the need to collect and remove the clippings.

During the course of the last 50 years mankind has automated many of the routine chores at home. Washing machines, dishwashers and dryers are found in almost every home in the western world these days. The next step in this natural evolution is to automate tasks that require motion in the space of the home or the garden, such as cleaning and mowing. A new category of home appliances is required in order to do this, appliances that are able to move in order to perform their tasks and avoid objects, pets and people in their way. This emerging new category of appliances is called Home Robotics, and we expect that in the years to come these machines will become as common in our homes as washing machines are today. Friendly Robotics® is focused on making and selling this exciting new generation of home appliances. Our products liberate people from routine chores such as cleaning the home and mowing the lawn, thus making our life more convenient and freeing our valuable time for more enjoying activities.
