Abstract
An electric dust pan having a housing with a forwardly extending lower section. The lower section includes an inlet opening and an upwardly and forwardly inclined bottom surface terminating at the inlet opening. An electric vacuum source is activated by a mercury switch when the housing is tilted forward from the upright position so that the inclined bottom surface contacts a floor surface. The inlet opening communicates with the suction side of the vacuum source and a dust bag held in the housing communicates with the discharge side of the vacuum source. A hinged top cover provides access to the dust bag and a handle of the top cover can be gripped by the user to move the housing from the upright position to the forward tilted position.
