A drain cleaner comprising:
- a drum rotatable about an axis of rotation, the drum including a rear wall and a bore formed in the rear wall;
- a nose assembly extending forwardly of the drum;
- a cable housed within the drum and extendable through the nose assembly;
- a first drive mechanism disposed on the rear wall and configured to drive rotation of the drum, the first drive mechanism including a spindle that is insertable into the bore, the first drive mechanism driven by an external motor, the first drive mechanism being coaxial with the axis of rotation;
- and
- a second drive mechanism disposed on the rear wall at an off-center location and configured to drive rotation of the drum, the second drive mechanism movable relative to the drum between a stowed position and an operational position, the second drive mechanism manually driven by an operator;
- wherein a portion of the rear wall surrounding the bore extends rearwardly from the drum a greater distance than the second drive mechanism when the second drive mechanism is in the stowed position.
