Abstract

A drain cleaning apparatus, includes a handle and a clog-catching member detachably connected the handle. Airplane-like wings project radially from the clog-catching member. The wings provide an angled projection that catches and holds a clump of debris in a drain pipe for unclogging the drain. Clog-catching members or smooth extension members can be connected end to end for different lengths. Different end tools can be removably connected to a clog-catching member or to a smooth extension member to provide multifunctionality. A drain cleaning harpoon that is an integral unit or one that can be assembled and disassembled is also provided. The harpoon can be fitted on one end with a plurality of J hooks, fish hooks, arrowheads or retractable barbs for catching and holding a mass of debris in a drain pipe.
