Abstract: A liquid dispensing device for a high pressure cleaning device is provided, and includes a liquid inlet, which is connectable to a pump outlet by a pressure conduit, a liquid outlet, an input apparatus, a display apparatus, and a control unit including a storage member in which control parameters are storable, and wherein at least one control parameter can be output from the control unit to the high pressure cleaning device. In order to further develop the liquid dispensing device to enable an improved cleaning result in a simple manner, the liquid dispensing device includes an object detection unit for contactlessly detecting the object to cleaned, wherein object information corresponding to the object to be cleaned is transmittable from the object detection unit to the control unit and is processable thereby for providing at least one control parameter adapted to the object to be cleaned.

Abstract: The disclosure relates to an electric drive unit that includes: a motor housing that surrounds an electric motor and has an external side; cooling fins configured on the external side of the motor housing; and an electrical module having components to be cooled. The electrical module is disposed in or on an additional housing that adjoins the motor housing, wherein the additional housing on the external side thereof has cooling fins that run in the same direction as the cooling fins of the motor housing.

Abstract: An electric drive unit includes a three-phase motor having a rotor, a stator, and a motor housing, wherein the stator has three coil windings that each include one winding wire having two coil connectors. The electric drive unit further includes a converter that provides the three-phase motor with a three-phase alternating current and has three terminal contacts. The coil connectors are connected to the terminal contacts by way of a star circuit or a delta circuit. The converter is implemented in a circuit board assembly having at least one circuit board. The terminal contacts of the converter are on the circuit board, and the connections, provided in the context of the star circuit or delta circuit, between the coil connectors and the terminal contacts of the converter, are implemented in that the respective ends of the winding wires of the coil windings are connected directly to the circuit board.

Abstract: The invention relates to a floor cleaning system, comprising a user-guided floor cleaning machine for cleaning a floor surface, a sensor device, a control device, and an actuatable display device, wherein the floor cleaning machine comprises an operating device for a user, a chassis for moving the cleaning machine over the floor surface, and at least one cleaning device having a cleaning tool and preferably a drive device for the cleaning tool, wherein, during operation of the floor cleaning machine, a cleaning path along which, proceeding from a starting point, the cleaning machine travels over the floor surface can be determined by the control device on the basis of signals from the sensor device, and wherein the control device actuates the display device in order to display cleaning-related information, depending upon the cleaning path along which the cleaning machine is determined to have traveled.

Abstract: The invention relates to a cleaning apparatus. The cleaning apparatus includes at least one cleaning tool for cleaning an object to be cleaned, an operating unit for a user, which includes at least one operating element for operating the cleaning apparatus, a control unit for processing operating instructions, a receptacle, arranged on the operating unit, for an external accessory that can be associated with the cleaning apparatus and that has a display device with an image display, wherein the accessory is removably positionable in the receptacle in a defined position, as well as a communication unit by way of which display information for being displayed on the image display are transmittable from the cleaning apparatus to the accessory positioned in the receptacle. The invention also relates to a cleaning system.
