This power rooter is a tough, easy-to-use machine. It has a rugged powder coated steel frame with roll bars to protect the motor and heavy-duty roller bearings in the cage for longer life and greater motor efficiency on long runs. The large cage holds 100 feet of 3/4" or 5/8" Flexi Core(R) cable to clear tree roots and other difficult obstructions in 3" to 10" drain lines.
