Abstract

A cable coil support assembly installable in an appropriate seating space of a vacuum cleaner comprises a cable drum having a hollow hub rotatably supported on a bearing pin axially projecting from a fixed supporting wall of the assembly. The hub is provided with radially oriented openings in communication with a suction space of the vacuum cleaner, whereby cooling air is drawn between adjacent winding of an electrical cable on the cable drum. The supporting wall is provided with at least one opening enabling gaseous communication between the cavity in the hub and the suction space of the vacuum cleaner.
