This invention relates to a device and system for cleaning the interior of conduits, gun barrels, or pipes, including drain pipes. The pipe cleaning device of the present invention is capable of (a) penetrating and removing restrictions that block flow, (b) scouring the interior wall of conduits or pipes to remove the buildup of undesirable solids that result in flow restriction, and (c) coating the wall of the pipe with a suitable substance. The present invention comprises a connecting member housed within a bendable or flexible conduit, a retraction handle attached to one end of the connecting member, and elastic or flexible strands attached to the opposite end of said connecting member. The strands are outwardly expandable in a radial dimension when said connecting member is retracted. The system of the present invention further comprises a pressure/suction source coupled to the conduit.
