Abstract
A vacuum dustpan, including a vacuum unit with interior ducting terminating in marginal nozzles extending along the bottom periphery of a housing, with multidirectional rollers supporting the vacuum unit, and a separate charging nest for charging operations.
Claims5
Vacuum dustpan apparatus for collecting dirt from a supporting floor surface and comprising:
- a housing formed with downwardly projected peripheral walls terminating in respective bottom edges to define a bottom side, said housing including downwardly opening marginal nozzles co-extensive with said edges and extending around the periphery of said bottom side, said housing including a motor mount;
- ducting formed with a vacuum impeller inlet and leading from said nozzles toward said motor mount;
- a dust collection bowl;
- a vacuum impeller interposed between said inlet and said bowl;
- a motor mounted on said motor mount and connected with said impeller;
- a rechargeable battery pack mounted on said housing and connected with said motor;
- a charger for connection with said battery;
- and
- multidirectional rollers mounted under said housing for supporting said nozzles in close spaced relation with respect to said floor surface to be cleaned whereby said housing may be rolled in any direction on said floor supported on said rollers to different selected locations and said motor energized to draw a partial vacuum in said nozzles so that dirt may be swept across said floor from any direction to be disposed proximate one of said nozzles to be drawn thereto.
