A dust collecting apparatus for a vacuum cleaner is provided. The dust collecting apparatus includes a centrifugal separating portion, a dust receptacle to collect dust which is separated by the centrifugal separating portion and a filter portion having a filter unit separating dust from an air current discharged from the centrifugal separating portion. The filtering portion further includes a dust removing unit to detach the filter dust caught in the filter unit, and a dust discharge member to move the filter dust to an upstream of the centrifugal separating portion.
