Abstract
A robotic cleaning apparatus is disclosed. The apparatus includes an automatically controlled cleaning machine and coded reflective targets used to provide information to the cleaning machine for positioning it along desired cleaning paths. The apparatus determines it position on a real time basis, particularly in the case of obstacles that are encountered by the cleaning machine during its cleaning operation. Hardware and software are provided for controlling movement of the cleaning machine relative to side and end walls of the floor surface section being cleaned, as well as controlling the functions of cleaning equipment.
