A device 1 has a housing 3 with a spindle 9 installed therein. A carrier 11 can be rotated around this spindle while moving along it. There are two nozzles 23 and 25 installed in the cylinder wall 21 of the device 1, which nozzles comprise a connecting piece 27 to which a water hose can be connected. For having the water jet rotate a carrier-mounted filter 13 the nozzle openings 29, 31, seen in axial direction of the spindle, are directed at the filter beside the spindle 9. For cleaning the filter a water hose is first to be connected to the nozzle 23 after which it is to be connected to the nozzle 25. As a result of the force of the water jet the filter 13 starts rotating around the spindle, so that the filter moves upwards and downwards along the spindle 9 in a rotating fashion. All parts of the filter then pass by the water jet during this operation. |
