Abstract: 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.

Abstract: The present invention relates to polypeptides comprising a enzymatically non-active cell wall binding domain of an endolysin or another cell wall lysing enzyme, and a sequence according to SEQ ID NO: 1 or derivatives thereof, wherein the polypeptide besides the cell wall binding domain comprises no further domains of an endolysin, as well as means for their preparation. The present invention further relates to methods for binding, enriching, removing from a sample, capturing and/or detecting bacteria, particularly gram positive bacteria.

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.

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: The invention relates to a dirt-collecting device for a floor-cleaning machine, for picking up a liquid from a floor surface which is to be cleaned, having a carrier and at least one wiping member for wiping the floor surface, the carrier and the at least one wiping member bounding a suction channel which opens out into a suction mouth and of which the free cross-sectional area, through which a suction stream can pass, decreases, at least in one channel portion, in a direction away from the suction mouth. In order to produce such a dirt-collecting device in a more cost-effective manner, it is proposed according to the invention that the suction channel has disposed in it at least one channel-narrowing member, which is produced separately from the carrier. The invention also relates to a floor-cleaning machine having such a dirt-collecting device.

Abstract: The invention relates to a method for operating a cleaning device with a drive motor which drives at least one cleaning tool. In order to develop the method further in such a manner that the degree of wear of the cleaning tool can be determined in a simple manner even when the cleaning tool is replaced, it is suggested in accordance with the invention that a wear value, which corresponds to the degree of wear of the cleaning tool present at the time the wear value is stored, be stored in a memory element of the cleaning tool and that this wear value be repeatedly updated. In addition, a cleaning device and a cleaning tool for carrying out the method are suggested.

Abstract: The invention relates to a cleaning tool for a cleaning device, the cleaning tool being subject to wear during operation. In order to make it easier to identify wear, the invention proposes that the cleaning tool comprise a sensor device with a sensor element which has a physical characteristic variable which changes as a function of the degree of wear of the cleaning tool. The invention also proposes a cleaning device having such a cleaning tool, the cleaning device having a detector device which is coupled to the sensor device for the purpose of sensing the change in the physical characteristic variable of the sensor element, and having an indicator device which is connected to the detector device.
