Claim:
A cleaning device ( 1 ) for hose filters comprising: a cleaning head ( 5 ) having a plurality of nozzles ( 11 ), said plurality of nozzles being axially spaced along said cleaning head ( 5 ) and rotatably connected to said cleaning head ( 5 ) so that said plurality of nozzles rotate about a longitudinal axis (L) of said cleaning head ( 5 ), said cleaning head ( 5 ) including a fixed jacket ( 15 ) fixedly connected to said cleaning head ( 5 ) so that said jacket ( 15 ) cannot rotate relative to said cleaning head ( 5 ), said jacket ( 15 ) having a smooth outer surface which surrounds said plurality of nozzles ( 11 ) at a distance and in which a series of through holes ( 17 ) are formed, said through holes being axially distributed over the circumference of said jacket ( 15 ) in a plane substantially perpendicular to the longitudinal axis (L) of said cleaning head ( 5 ) and being arranged with respect to said plurality of nozzles ( 11 ) such that a jet emerging from each of said plurality of nozzles ( 11 ) during operation can pass through a through hole ( 17 ) at least intermittently, wherein said cleaning head ( 5 ) produces a pressure during operation which holds said cleaning head ( 5 ) at a distance from said hose body ( 2 ) and the distance between the plurality of nozzles ( 11 ) and the jacket ( 15 ) is between 8-15 ram.
