ABSTRACT:
A device for cleaning an inner pipe which comprises a nozzle head comprised of a feed borehole axially disposed therein, at least two rotation nozzles communicating with the feed borehole, at least two cleaning nozzles communicating with the feed borehole and a shaft. A rinsing nozzle communicates with the feed borehole and extends upwardly at an angle from the longitudinal axis of the feed borehole. The shaft is received in an outer sleeve whereby when the device is inserted into an inner pipe and a medium is flowed through the borehole and out of the rotation nozzles a force is generated when the medium emerging from the rotation nozzles contacts the wall of the inner pipe which force causes the nozzle head to rotate.
