ABSTRACT:
An apparatus is shown for cleaning a pipe. The apparatus includes a rigid stem and a motor stationarily mounted on the stem. An outer body surrounds the motor and is rotatably mounted on the rigid stem. A fluid conduit is connected to the stem and to a source of fluid under pressure for supplying fluid to the motor for driving the motor. The fluid conduit also connected to a pulling unit for pulling the apparatus through the pipe to be cleaned. Fluid supplied through the fluid conduit to the stem and through the stem to the fluid powered motor provides rotational propulsion to turn the outer body as the apparatus is moved through the pipe to be cleaned.
