Abstract: A heatable high pressure cleaning appliance is provided with an undercarriage and a housing lower part, arranged on the undercarriage, in which a motor and a pump driven by the motor for pressurizing water are arranged, and with a fuel-operated heat exchanger for heating the water and a fuel tank for storing liquid fuel for the heat exchanger. In order to further develop the heatable high pressure cleaning appliance in such a way that it has a high mechanical stability and is producible in a cost-effective manner, it is proposed that the fuel tank is configured as a one-piece plastic hollow body, which forms the housing lower part and is held on a rigid support frame, wherein the support frame forms a shock protector that at least partially surrounds the fuel tank in the circumferential direction.

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 cleaning cart, comprising a frame having a frame lower part, a frame upper part and support parts which connect the frame lower part to the frame upper part and are spaced apart from one another, rollers at the frame lower part for moving on a ground surface, storage devices for receiving therein and/or supporting thereon cleaning accessories, retaining elements for holding the storage devices, and receiving elements arranged at the support parts in a predefined position, wherein the retaining elements are selectively fixable to the receiving elements for having the storage devices assume different relative positions with respect to the support parts.

Abstract: The invention relates to a cleaning system comprising a hand-guided cleaning cart which comprises rollers and is movable over a supporting surface, for transporting and storing cleaning utensils for manual cleaning, wherein the cleaning system comprises at least one receiving device arranged at the cleaning cart and two or more different functional devices for operation and/or use of the at least one cleaning cart, wherein the functional devices are selectively connectable to the at least one receiving device, and wherein the at least one receiving device and the functional devices comprise cooperating connecting elements.

Abstract: The present invention relates to a connection device for connecting a first cleaning cart to a second cleaning cart along a connecting direction, each configured for receiving cleaning utensils and comprising rollers for moving on a ground surface, wherein the connection device comprises a first connecting part fixed or fixable to the first cleaning cart and a second connecting part fixed or fixable to the second cleaning cart, wherein the respective connecting part comprises a base region and a projection region projecting therefrom in a direction towards the respective other connecting part, wherein a first locking element is arranged at the first projection region of the first connecting part and a second locking element is arranged at the second projection region of the second connecting part, wherein the locking elements are configured to be in engagement with one another when in a locking position and to be out of engagement when in an unlocking position, and wherein the projection regions are arranged

Abstract: The invention relates to a cleaning system, comprising a cleaning cart and an external accessory device, wherein the cleaning cart comprises a frame having rollers for moving on a ground surface, at least one receptacle for receiving and/or carrying cleaning utensils, and an interaction device having a hand-actuatable interaction element, wherein the accessory device is portably configured and a user application program for processing cleaning-related information is executably stored on the accessory device and/or operable via the accessory device, wherein the interaction device and the accessory device are coupleable with one another via a communication connection, and wherein, depending on an actuation of the interaction element by the user, input information for operation of the user application program is transmittable from the interaction device to the accessory device and is processable by the accessory device. The invention further relates to a method for operating a cleaning system.
