Abstract

A dust-collecting device for a vacuum cleaner comprising a dust-collecting case which is fitted into a suction path extending from a suction nozzle to a motor fan and from which accumulated dust can be discharged by opening a bottom lid of the dust-collecting case, and a cylindrical filter fitted into the dust-collecting case. The filter is arranged to be rotatable, a spiral rib is formed at an outer periphery of the filter, and the device is equipped with a rotating means for rotating the filter. Dust which cannot be discharge by its own weight since it is in a compressed state can be pushed out through the spiral rib formed on the outer periphery of the filter by rotating the filter, so that dust accumulated within the dust-collecting case in a compressed state can be easily discharged.
