Abstract: The invention relates to a method for cleaning a floor surface with a floor cleaning device, in which method, during the cleaning movement of the floor cleaning device over the floor surface, a first recording of a floor surface portion before the cleaning is created with an optical recording unit, the floor cleaning device is moved with at least one cleaning unit over the floor surface portion, which is cleaned, a second recording of the floor surface portion after the cleaning is created with an optical recording unit and the recordings are compared with one another in order to check the cleaning result. The invention further relates to a floor cleaning device for carrying out the method.

Abstract: A cleaning tool for a floor cleaning machine is proposed which includes a cleaning-action device and a supporting part on which the cleaning-action device is arranged and by means of which the cleaning tool is fixable to the floor cleaning machine, wherein the supporting part includes a seating having a wall and a seating space for a tool holding head of the floor cleaning machine which is bounded by the wall, and the wall includes a holding region for the tool holding head, wherein the wall includes an insertion region for the tool holding head to which the holding region is adjoined, wherein the seating space is widened in the insertion region in comparison with the holding region and tapers towards the holding region.

Abstract: A window-cleaning robot that includes: a powered agitator that, when active, mechanically removes debris from a window surface; a cleaning pad, which is wetted with a cleaning fluid and contacts the window surface so as to remove debris therefrom with the aid of the cleaning fluid; and a movement system, for example including a number of wheels, which moves the robot over the window surface and has a defined forwards direction; the agitator is located forwards of the cleaning pad and the agitator and the cleaning pad are arranged such that, as the robot moves over the window surface in the forwards direction, the agitator addresses a width in a width direction, which is perpendicular to the forwards direction and parallel to the window surface, that is greater than the width addressed by the cleaning pad.

Abstract: A suction unit comprising a suction apparatus, a dirt collection container, a filter device, wherein the dirt collection container is connected in terms of flow via the filter device to the suction apparatus, and a cleaning device for the filter device, which cleaning device comprises an external-air valve device, and at least one guide duct for air, which at least one guide duct has a first port which is connected in terms of fluid action to the cleaning device for the provision of external air from the at least one guide duct, a second port for the coupling of exhaust air of the suction apparatus into the at least one guide duct, and a third port which is connected in terms of fluid action to the surroundings of the suction unit, wherein air from the surroundings is configured to flow into the at least one guide duct via the third port.

Abstract: A self-propelled, self-steering floor cleaner is provided, including a cleaning device with at least one cleaning unit for cleaning a floor surface of a room having at least a section of an obstacle therein that is not in contact with the floor surface, a transmission unit for emitting radiation directed at the obstacle and the floor surface, a detection unit for detecting reflected radiation and providing a detection signal, a control unit coupled to the detection unit, and a chassis for movement on the floor surface including a drive unit coupled to the control unit, it being determinable from the detection signal whether a space and a cleanable floor surface section are present underneath the obstacle, the drive unit being actuatable to move the floor cleaner for cleaning the floor surface section, with at least one cleaning unit. The invention also relates to a method for cleaning a floor surface.
