Abstract: A floor cleaning apparatus is provided, including a dirt collection device for picking up dirty liquid from a floor surface to be cleaned as well as a dirty liquid tank, into which the dirty liquid can be transferred. In order to provide a floor cleaning apparatus of this type, which can be handled in a more user-friendly manner, it is proposed that the floor cleaning apparatus has a tank rinsing mechanism with at least one rinsing line, which includes at least one inlet opening for rinsing liquid, which can be provided for the tank rinsing mechanism, as well as at least one outlet opening for delivering rinsing liquid into an interior of the dirty liquid tank.

Abstract: The invention relates to a cleaning appliance, wherein in order to access same, an access authorization stored on an authorization carrier is required, the appliance including two or more authorization carriers with access authorizations stored thereon which are linked to different authorization profiles, and a detection unit for detecting the access authorization of an authorization carrier, wherein a range of functions dependent on the authorization profile linked to the access authorization can be provided to an operator by the cleaning appliance. In order to provide such a cleaning appliance which is more user-friendly in operation, it is proposed that each authorization carrier comprises an identification device for providing an identifier which is associated with the particular authorization profile of the authorization carrier and which is perceivable by the operator using a sensory organ, wherein identifiers associated with different authorization profiles are different from one another.

Abstract: A method is proposed for operating a cleaning appliance which comprises a control device as well as at least one cleaning element for cleaning a surface which has a memory element. The control device comprises a control memory member and the control device is connected to a reader for reading the memory element. In order to reduce the risk of the user unintentionally using an unsuitable cleaning element, it is suggested that characterizing data distinguishing the type of cleaning element be stored in the memory element, these data being read and evaluated in the period of time from the starting up of the cleaning appliance up to the beginning of the cleaning action of the cleaning element. In addition, a cleaning appliance for implementing the method is suggested.
