ABSTRACT:
Drain cleaning apparatus comprises a housing in which a drain cleaning cable is coiled and from which the cable is displaced for introducing an outer end of the cable into a drain to be cleaned. The housing is stationary and the cable is rotated about its axis relative to the housing by a drive motor coupled to an inner end of the cable. A manually operable cable feeding device can be coupled with the housing for feeding the cable outwardly and inwardly relative to the housing.
