You can remove the drum in seconds for more portability or to switch to a different diameter cable – with no mess and no lost time. A distributor tube inside the drum allows you to feed cable in and out without chucking and releasing the cable every few feet – so you finish quicker. An optional Power Cable Feed drives and retracts the cable at up to 16 feet per minute. The drum carries up a 50 ft of 3/8” cable to clear 2” to 3” lines, or 1/2” cable for heavier work in 4” lines. For small drain work, you can order your Mini-Rooter Pro with a J-Drum for handling smaller, more flexible cables. Some Mini-Rooter Pro safety features: A foot pedal that uses air pressure to start and stop the machines, with no electrical wiring between the pedal and motor, a ground fault circuit interrupter, and a high impact plastic guard covering the motor pulley.
