Abstract
A vacuum cleaner with a self-cleaning filter and a sweeper stand that also functions as an electric dustpan when the vacuum is seated within the sweeper stand is provided. The vacuum includes a housing having an air inlet at one end of the housing and a handle at the other end of the housing. An air passageway includes a deflector to direct dirt into a dirt collection tray which is pivotably mounted to the housing. A filter mounted on the motor divider wall and a filter cleaning arch mounted on the dirt collection tray so that the filter cleaning arch strikes the filter to dislodge dirt collected on the filter as the dirt collection tray pivots open. The sweeper stand includes a housing for receiving the hand vacuum, an opening for directing dirt laden air into an air inlet of the hand vacuum. Power switches to actuate the hand vacuum when the hand vacuum is seated in the sweeper stand are provided.
