A system provided with a base station (2) comprising a signal emitting module, a self movable robot comprising at least an energy storage, a sensor for sensing this signal emitted by signal emitting module of the base station and a processor for controlling the movement of the robot by means of the sensed signal to return the robot to the base station. The robot comprises means for controlling the movement of the robot to move the robot randomly over a surface, whereby the absolute position of the robot is not memorized, means for marking the interrupt location (5) where the movement of the robot is interrupted to return to the base station and means for returning the robot from the base station to the interrupt location (5) by means of said marking.
