A mobile surface maintenance machine embodiment includes a mobile body, a solution tank for containing a cleaning fluid, wheels for supporting the mobile body, a maintenance tool(s), an output channel, an electric power source, a first electric motor, and a pressure washer. The pressure washer includes a spray wand, a pressure pump, and a second electric motor. The pressure pump is fluidly coupled to the spray wand and to the solution tank. The pressure pump is configured to pressurize the cleaning fluid supplied to the spray wand. The second electric motor is operatively coupled to and configured to drive the pressure pump. The second electric motor is configured to receive electric power from the electric power source and is commonly powered by the electric power source that provides power to the first electric motor. The second electric motor is separate from the first electric motor.

A cleaning robot including: a main body; a drive device; and a cleaning device equipped for wet-cleaning floors to be cleaned, wherein: the main body, on the side facing the floor to be cleaned, is assigned a receptacle unit, a first mop pad configured for wet-cleaning is fastened to the receptacle unit, and the cleaning robot is configured to autonomously exchange the first mop pad fastened to the receptacle unit for a second mop pad.

A system with a first floor processing device and a second floor processing device that is designed to orient and localize itself within an environment based on an area map. The first floor processing device is set up to detect a movement path during a movement by the first floor processing device and transmit information about the detected movement path to the second floor processing device. The second floor processing device has a control and evaluation unit that is set up to analyze the received information and, based upon the movement path detected by the first floor processing device and/or a partial area of the environment not traversed by the movement path, enter a no-go area into the area map which the second floor processing device is not allowed to traverse.

An automatically moving floor treatment appliance has an appliance housing, a drive, a detector for detecting surrounding area features, and a computer that transmits control commands to the drive, based on the surrounding area features detected by the detector. The detector has a plurality of inner and outer fall sensors arranged on an underside of the appliance housing, which detect a distance of the floor treatment appliance from the surface. The computer controls the drive to change a movement of the floor treatment appliance when the distance detected by the fall sensor is greater than a threshold value defining a slope. The fall sensors are interconnected in an evaluation circuit of the detection means so that the detection signals of the totality of inner fall sensors can be evaluated independently of the detection signals of the totality of outer fall sensors.
