A device has a housing with a spindle installed therein. A carrier can be rotated around this spindle while moving along it. There are two nozzles installed in the cylinder wall of the device, which nozzles comprise a connecting piece to which a water hose can be connected. For having the water jet rotate a carrier-mounted filter the nozzle openings seen in axial direction of the spindle, are directed at the filter beside the spindle. |
