ABSTRACT:
A sewer unclogger having a small motor at its leading end and a length of coiled rod or a snake for pushing the motor through a clogged sewer pipe, the motor having at its lead end a grapple hook or a cutter for removing the clog. When a grapple hook is used, the rotating motor rotates the grapple hook until it grabs onto the obstruction, wherein the motor can be disengaged from the rod or shut off and the rod used to retract the motor grapple hook and obstruction from clogging the pipe. Various embodiments are described including a pneumatically driven motor which uses a pneumatic tubing to both supply compressed air and to serve as the snake for pushing the motor through the pipe, a battery pack motor, and a electric motor where a common electrical conductor and rod are used to both supply electric power and push the electric motor through the pipe.
