Abstract: A hand-operated sweeping machine having two circular brooms mounted in the front area, a motor drive which rotates the circular brooms, a drive mechanism which transfers a driving force derived from the forward motion of the sweeping machine to drive the circular brooms when the motor drive is not operating, and an interrupting mechanism which automatically interrupts a connection between the motor drive and the driving mechanism when the motor drive can rotate the circular brooms faster than the driving mechanism. When the motor drive of the sweeping machine is inoperative, as when there is no electricity available to operate an electric motor drive, the sweeping machine may be operated by the driving mechanism driving the circular brooms. The interrupting mechanism automatically prevents the motor drive when operating from transferring driving force to the driving mechanism and thereby undesirably driving forward motion of the sweeping machine.

Abstract: The present invention relates to a horizontally movable and downwardly biased appendage that extends laterally from a surface treating apparatus, such as a robotic floor cleaner. The robotic floor cleaner and/or appendage may use disposable cleaning sheets, such as dust clothes, wipes, sheet-brushes, and the like, to clean under objects or into corners but does not substantially interfere with the rotation of the surface treating apparatus about its axis when it is adjacent to encountered obstacles. The appendage can extend under low hanging obstructions to remove dirt, and reach into corners innavigable or unreachable by the robotic floor cleaner.
