Abstract
A drain cleaner includes a housing and inner and outer drums disposed in the housing. The inner drum is rotatable relative to the housing. The inner drum and the outer drum form an annular drum channel for receiving a drain cleaning cable. The inner drum defines an inner drum chamber. A drain cleaning cable is disposed within the annular drum channel. The drain cleaner includes a ferrous pick-up plate. The pick-up plate rotates with the inner drum. A sensor detects rotation of the ferrous pick-up plate.
