Propulsion of the cleaning device is produced in a flow direction (FM) by application of medium in the tube, or propulsion of the cleaning device is produced by engagement of a traction element counter to the flow direction of the medium. A liquid medium is passed at an end of the cleaning tube or a pipe to be cleaned portion in a purification unit, in a mobile filter and/or water treatment plant. An independent claim is also included for a cleaning apparatus.
