Abstract: A cleaning appliance is provided including at least one authorization carrier with an access authorization which is provided thereon and is required for accessing the cleaning appliance, just one receptacle in which the at least one authorization carrier is positionable, and a detection unit, situated at the receptacle, for contact-based detection of the access authorization of an authorization carrier positioned in the receptacle, the detection unit having at least one detection contact element which contacts the access authorization. To provide a cleaning appliance of this type which is usable with greater versatility, it is proposed that the cleaning appliance include two or more authorization carriers with access authorizations provided thereon which are linked to different authorization profiles, wherein a range of functions dependent on the authorization profile linked to an access authorization can be provided to an operator by the cleaning appliance.

Abstract: A motor pump unit for a high-pressure cleaning apparatus has an electric motor and a pump. The electric motor has a motor housing that is surrounded by a cooling housing with an annular space having an annular space inlet and an annular space outlet formed therebetween. The pump has a drive housing on which is supported the motor shaft, and has a suction inlet and a pressure outlet. The annular space outlet is fluidly connected to the suction inlet and liquid to be pressurized by the pump is suppliable to the annular space inlet. In order to improve the motor pump unit such that the heat load on the drive housing can be reduced, the drive housing has at least one cooling passage which is arranged upstream of the suction inlet and through which the liquid to be pressurized can flow.

Abstract: A washing element for a washing system is provided, in particular an automatic motor vehicle washing system, wherein the washing element is formed by a foam material. To provide a washing element of this kind wherein the risk of damage to the article to be washed can be reduced, the washing element is a foam sheet which has at least on one side a skin, wherein the skin is provided, at least in certain sections, with a surface texturing.

Abstract: A mobile floor cleaning machine is provided, having a chassis on which running wheels are rotatably mounted, and having at least one cleaning unit which has at least one cleaning tool and is coupled to the chassis via a guide member. To improve the floor cleaning machine in such a way that the risk of damage to the floor cleaning machine or to an obstacle in the event of a frontal collision with the obstacle may be minimized, it is proposed that the guide member is elastically deformable in the longitudinal direction of the floor cleaning machine.

Abstract: The invention relates to a vacuum cleaning appliance having a moveable stand. A suction device mounted on the stand has a device upper part mounted on the stand and a dirt collection container situated beneath the device upper part. The stand has a lifting device and an actuating element pivotable about a horizontal axis for raising and lowering the dirt collection container, which in its raised position abuts against the device upper part in a flow-tight manner, and in its lowered position rests on a floor surface. The actuating element is configured as a push bar having a handle part which, in the raised position of the dirt collection container, may be gripped by the user in a standing posture in order to move the vacuum cleaning appliance, and is upwardly pivotable about the pivot axis by at most 135° in order to lower the dirt collection container.

Abstract: A rotor nozzle for a high-pressure cleaning appliance is provided. The rotor nozzle has a housing, which comprises at least one inlet opening tangentially, and which is provided in a front wall with a pan-shaped depression with a central opening. A nozzle body is arranged in the housing and supported with a spherical end in the pan-shaped depression. A longitudinal axis of the nozzle body is inclined to the longitudinal axis of the housing, it being possible for liquid in the housing to be caused to rotate about the longitudinal axis, and the nozzle body rotating together with the rotating liquid. In order to reduce flow losses in the rotor nozzle, without the operation of the rotor nozzle (in particular, start-up behavior of the nozzle body) being noticeably impaired, the nozzle body is provided with an outer contour deviating from the circular shape in a rear end area.

Abstract: The invention relates to a cleaning apparatus, comprising an operating unit for operating the cleaning apparatus, at least one functional unit for carrying out an operating instruction, and a control unit for receiving operating instructions performed on the operating unit and controlling the at least one functional unit based on said operating instructions, wherein an access authorization stored on an authorization carrier is required in order to operate the cleaning apparatus. In order to provide such a cleaning apparatus with a more user-friendly access control, it is proposed that the cleaning apparatus have a detection unit operatively connected to the control unit and configured for contactless detection of the access authorization and transmission thereof to the control unit, and that the access authorization be verifiable for its validity by the control unit. The invention further relates to a method for controlling access to a cleaning apparatus.

Abstract: A manually guided floor cleaning machine is provided, including a chassis with a front end and a rear end in relation to a straight ahead forward travel direction, a wheel arrangement, which is arranged on the chassis in the region of the rear end, and a cleaning head, which is pivotably arranged on the chassis in the region of the front end, wherein there is provided a steering rod device, which is articulated on the cleaning head, which is supported on the chassis and which extends upwardly in a direction away from the chassis toward the rear end.

Abstract: A manually guided floor cleaning machine is provided, including a chassis with a front end and a rear end in relation to a straight ahead forward travel direction, a wheel arrangement, which is arranged on the chassis in the region of the rear end, and a cleaning head, which is pivotably arranged on the chassis in the region of the front end, at least one brush being arranged on the cleaning head and a drive device being arranged for the driven rotation of the at least one brush, a rotational axis of the at least one brush being parallel to a wheel axis of the wheel arrangement in the straight ahead forward travel direction.

Abstract: The invention relates to an automotive sweeper with wheels for traveling along a ground surface and with at least one sweeping brush rotatingly drivable for sweeping the ground surface and with a dirt container adapted to be acted upon with a vacuum by a suction unit via a suction conduit and connected to a suction port via an intake line for the purpose of receiving sweepings. In order to develop the sweeper further in such a manner that it achieves an improved cleaning result with as little use of energy as possible it is suggested in accordance with the invention that the suction conduit be integrated into the dirt container at least in sections, wherein the outlet of the intake line opening into the dirt container is arranged next to at least one inlet area of the suction conduit.
