The Robomow RL2000 is an automatic lawnmower that cuts the grass all by itself. All you have to do is schedule a weekly program. It will depart from the base station at the pre-set scheduled days and times. At the end of each operation, Robomow returns to the base station for charging until the next scheduled operation. Your lawn will be maintained even when you are away from home! RL2000 is the top of the range model and is designed to mow big domestic lawns. It's environmentally friendly because it uses no gas or oil and has no emmissions.
