Abstract
A cleaning unit for cleaning travel equipment allows the travel equipment to be shifted from an operating mode to a cleaning mode. The cleaning equipment is an escalator or a moving walkway which has tread units connected with an endless conveyor. The cleaning unit can be mounted as a substitute for a tread unit of the travel equipment during a cleaning sequence and includes cleaning elements. The travel equipment can be shifted from an operating mode to a cleaning mode in which the cleaning equipment is substituted for one or more tread units and the travel equipment operated whereby a cleaning sequence is performed. After cleaning is performed, the equipment is stopped, the cleaning equipment removed, and the removed treads reinstalled.
