Abstract: A device for sucking up particles to be collected, in which at least one collecting compartment for collecting these particles is connected via an inlet opening of a partition to a suction device located inside at least one accommodating compartment. The collecting compartment is connected to the suction device in a manner that enables an airflow to be guided from the collecting compartment to the suction device. The partition contains, as an inlet opening, an air guiding funnel whose inlet surface forms a significant portion of the partition surface.

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.
