ABSTRACT:
A self-propelled pipe cleaner uses a body shaped to conform to the inside of a pipe with the axial extent of the body covered with a bristle pile material extending outward from the body to engage the inside of the pipe. The pile has resilient bristles uniformly inclined rearwardly relative to a forward direction of motion of the body. A vibrator is mounted within the body and energized for vibrating the body reciprocally and axially so the bristles engaging the inside of the pipe move the cleaner forward through the pipe for cleaning the pipe.
