A drain cleaner including a cable configured to be inserted into a drain, a drum supporting the cable, a first motor operable to rotate the drum, and a cable feed control mechanism configured to feed the cable in a linear direction along a first axis. The cable feed control mechanism includes a second motor, a drive wheel rotatable by the second motor about a second axis that is perpendicular to the first axis, and a driven wheel rotatable about a third axis that is parallel to the second axis. The drive wheel and the driven wheel are configured to engage the cable to feed the cable along the first axis.

A power tool adapter for a drain cleaning device is disclosed herein. The power tool adapter includes an adapter body having a proximal end portion and a distal end portion, the proximal end portion of the adapter body being oppositely disposed relative to the distal end portion of the adapter body. The distal end portion of the adapter body is configured to be coupled to a drain cleaning device having a plurality of hook elements disposed thereon, the plurality of hook elements configured to grab and collect debris from a drain pipe; and the proximal end portion of the adapter body is configured to be coupled to a rotary motion input device that is sufficient to rotate the plurality of hook elements of the drain cleaning device about a rotational axis so as to grab and collect the debris from the drain pipe.

A tool for opening or removing a blockage from a drain is shown. In one embodiment, the drain cleaning tool includes a drum, a spinning handle, a support handle, a cable, and a cable lock assembly. The spinning handle is coupled to the drum and rotatable to coil the cable after use of the drain cleaning tool. The support handle is positioned between the drum and a tip of the drain cleaning tool. In another embodiment, the drain cleaning tool includes a tip portion, a body, a handle, and a cable. The drain cleaning tool further includes a flexible portion of the cable and retention mechanism such that the drain cleaning tool can be folded.

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 machine includes a brushless direct current (DC) motor configured to rotate a snake about the snake axis. An electronic processor is configured to control power switching elements to drive the brushless DC motor. In a first operating range when a load experienced by the brushless DC motor is less than or equal to a predetermined load, the electronic processor is configured to control the power switching elements to drive the brushless DC motor at an approximately constant speed regardless of the load experienced by the brushless DC motor. In a second operating range when the load experienced by the brushless DC motor is greater than the predetermined load, the electronic processor is configured to control the power switching elements to drive the brushless DC motor at a decreasing speed as the load experienced by the brushless DC motor increases.

A drain cleaner includes a shroud with a closed end and an open end opposite the closed end and a drum assembly positioned within the shroud. The drum assembly is rotatable relative to the shroud. The drum assembly includes an inner drum and a drum cover extending entirely over an open forward end of the inner drum. The drain cleaner also includes a flexible cable stored within a cavity defined by the inner drum and the drum cover of the drum assembly. The flexible cable is supported by the inner drum. The drain cleaner further includes a handle assembly coupled to and extending rearwardly from the shroud. The handle assembly includes a motor, a grip, and an actuator to selectively energize the motor. The actuator is positioned in an area defined between the grip and the shroud.

A drain cleaning device including a drum, a cable positioned within the drum, a motor coupled to the drum to rotate the drum, a cable feed device operable to extend the cable out of the drum and retract the cable into the drum, a sensor operable to detect a performance characteristic of the drain cleaning device, and a controller coupled to the sensor and to the motor, the cable feed device, or both. The controller is configured to receive a signal from the sensor indicative of the performance characteristic of the drain cleaning device, and send an instruction to the motor, the cable feed device, or both to change an operating parameter of the motor, the cable feed device, or both based on the signal received from the sensor.

A drain cleaning device includes a frame and a drum assembly supported by the frame. The drum assembly includes an inner drum, an outer drum, and a space defined therebetween. The drum assembly is configured to rotate about an axis of rotation. The drain cleaning device also includes a motor supported by the drum assembly. The motor includes an output shaft. The drain cleaning device further includes a flexible cable stored within the space. The flexible cable defines a first end and a second end opposite the first end. The first end is coupled to the output shaft to receive torque from the motor. The drum cleaning device also includes a battery receptacle supported by the drum assembly. The battery receptacle is configured to receive a battery pack that supplies power to the motor.

An improved drill bit is a drill bit designed for use with a drain snake unclogging apparatus for sewer pipes having an arrowhead shaped point attached to a short drill bit sized for sewer pipes and having helical grooves along its length for material that has been cut or loosened by the pointed chisel bit to move rearward through the grooves away from the clogged material. The bit is more effective for solid plugs within a pipeline in that it cuts the clogging material into pieces instead of being design for gripping and pulling the clog.
