Abstract
A drain cleaning device includes a drum, and a cable positioned within the drum. The cable is operable to be extended out of the drum and into a conduit. The drain cleaning device also includes a motor coupled to the drum to rotate the drum, a sensor operable to detect a characteristic of the cable, and a controller coupled to the sensor and the motor. The controller is configured to receive a signal from the sensor indicative of the characteristic of the cable and send an instruction to the motor to change an operating parameter of the motor based on the signal received from the sensor.

A drain cleaning device comprising:
- a drum;
- a cable positioned within the drum, the cable configured to be extended out of the drum and into a conduit;
- a motor coupled to the drum to rotate the drum;
- a sensor operable to detect a characteristic of the cable;
- and
- a controller coupled to the sensor and the motor, the controller configured to:
- receive a signal from the sensor indicative of the characteristic of the cable, and
- send an instruction to the motor to change an operating parameter of the motor based on the signal received from the sensor.
A method of operating a drain cleaning device, the method comprising:
- providing the drain cleaning device including a drum, a cable positioned within the drum, a motor coupled to the drum, a sensor, and a controller coupled to the sensor and the motor;
- rotating the drum with the motor to spin the cable;
- extending the cable out of the drum and into a conduit;
- detecting, by the sensor, a characteristic of the cable;
- and
- changing, by the controller, an operating parameter of the motor based on the characteristic detected by the sensor.
