A drain cleaner assembly including a base unit having a housing, a first portion of a drive arrangement supported by the housing, and a motor coupled to the drive arrangement, where the motor is operable to selectively drive the drive arrangement. A drum unit is removably coupled to the base unit. The drum unit includes a rotatable drum, a cable stored within the drum and selectively extendable out of the drum and into a drain, and a second portion of the drive arrangement, where the second portion of the drive arrangement includes a driven shaft extending along an axis of rotation of the rotatable drum, where the driven shaft is rotatably fixed to the rotatable drum, and wherein the first portion of the drive arrangement is configured to drive the driven shaft and the rotatable drum when the drum unit is coupled to the base unit.
