A cleaning tool for a floor cleaning appliance is provided, including a main body carrying a cleaning cover which is subject to wear, and including a signal transmitter which provides a wireless signal in dependence upon the degree of wear of the cleaning cover. To be able to detect in a cost-effective manner when a maximum admissible degree of wear of the cleaning cover is reached, the signal transmitter is of rigid construction and fixed to a movable carrying part, the carrying part being held on the main body and being movable from a normal position to an evasive position against a restoring force, the carrying part protruding further from the main body in the normal position than in the evasive position, and the carrying part and/or the signal transmitter contacting the floor surface to be cleaned when a maximum admissible degree of wear of the cleaning cover is reached.

Cleaning tool for a floor cleaning appliance

A self-propelled surface cleaning machine is proposed, including a floor cleaning device, a steerable front wheel, a steering device associated with the front wheel, a rear wheel device having at least one left rear wheel and at least one right rear wheel, a first drive device for driving the front wheel, a second drive device for driving the rear wheel device and a differential device for the rear wheel device that allows different speeds of rotation for the at least one left rear wheel and the at least one right rear wheel.

Self-propelled surface cleaning machine and method for operating a self-propelled surface cleaning machine

A drivable floor cleaning machine is provided, including a chassis, at least one cleaning head, and a holding device capable of holding the cleaning head on the chassis and lifting it relative to the chassis, the holding device including a first rod device rotatably held by a first bearing device on the chassis, a second rod device rotatably held on the chassis by means of a second bearing device, a third bearing device rotatably holding the cleaning head on the first rod device, and including a fourth bearing device rotatably holding the cleaning head on the second rod device, wherein the cleaning head is supported on a stop when a specific lifting position of the cleaning head relative to the chassis is reached, and on which stop the cleaning head can be rotated.

Drivable floor cleaning machine and method for operating a floor cleaning machine

The invention relates to a floor cleaning appliance comprising a housing, on the underside of which is arranged at least one drivable cleaning tool for removing dirt from a surface to be cleaned, and further comprising a suction unit for vacuuming-off the dirt and a dirt container for receiving the vacuumed-off dirt. In order to so develop such a floor cleaning appliance that it is easier to service, it is proposed in accordance with the invention that the housing comprise a dirt container receptacle in which the dirt container is releasably positionable, and, in addition, at least one functional device receptacle for at least one functional device, the at least one functional device or a cover of the at least one functional device being freely accessible after removal of the dirt container from the dirt container receptacle.

Floor cleaning appliance

The invention relates to a floor-cleaning appliance having a housing, on the underside of which is disposed at least one floor-cleaning tool adapted to be driven in rotation or oscillation, wherein the floor-cleaning appliance, for the purpose of cleaning a floor surface, can be guided manually by the user in an operating direction along the floor surface. In order to develop the floor-cleaning appliance such that it can be transported in a simple manner, it is proposed according to the invention that the floor-cleaning appliance has transporting wheels which are adapted to be rotatably fixed by the user, for the purpose of transporting the floor-cleaning appliance, on wheel bearings disposed on the side of the housing.
