a strategic alliance for developing robotic vacuum cleaners. By 2004, the first model, Friendly Vac RV400, was on the market. Weighing in at 23 pounds, it is the largest robotic cleaner of all times. However, this line of products was discontinued, and the company now focuses only on robotic lawn mowers. Mowing All current Robomow models are able to mow grass inside a specified area by staying within an underground, electrified wire. The wire is installed around the mowing area by hammering it in with pegs just below the surface. Grass soon covers the wire so that it is not visible. Where areas within the specified are not to be mowed, 'islands' can be created by keeping two strands of the electrified wire together and creating internal areas. The mowing that Robomow does is directed in accordance with its movement algorithm, which is not straight up and down. Therefore, although no traditional mowing lines can be seen, Robomow covers the entire mowing zone within a few operations. In between mows, the mower's batteries are recharged at its docking/charging station which it returns to automatically. Robomow models RC/MC: these models have a 28 cm wide blade that fit any lawn of up to 1200m2. They can be installed outside of the lawn for not interrupting with the normal use of the lawn. RS/MS: these models have a 56 cm cutting width supported by two 28 cm blades, which are suitable for any lawn up to 3500m2.
