Abstract
A rotary drain and sewer cleaning apparatus includes a flexible elongate cable insertable into a line. An end of the elongate cable is attached in a drum and a portion of the elongate cable is wound in the drum. A motor rotates the drum. A power supply and switch selectively provide current to the motor causing the motor to rotate. A circuit includes a sensor for measuring a motor drive torque as the drum rotates and generating a torque signal representing motor drive torque level. An indicator is controlled by the torque signal and indicates the torque level.
