ABSTRACT:
A cleaning apparatus, having a motor, a rotatable scouring head, an inflatable collar, a frame fixed to the motor and collar, a swivel coupling on the frame, and a conduit for supplying fluid under pressure to the inflatable collar through the swivel coupling, is introduced into a pipe to be cleaned. The collar is inflated to fill the pipe cross-section. Fluid is then supplied under pressure into the pipe to propel the apparatus through the pipe and to actuate the motor thereby rotating the scouring head which scours the inner wall of the pipe.
