Estimating the term…
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.
