Abstract
A miniature electrically powered surface sweeper having a rotary brush element which is adapted to come in direct contact with a surface to be cleaned. The brush element is disposed within a housing having a curved inner wall surface which contacts the bristles as the same move inwardly within the housing to prevent loss of dust particles. A receptacle element is provided with a movable trap opened by the moving of an electrical switch to closed position to power the brush element, and closed when the switch is opened to discontinue operation of the brush element. The brush element includes bristles which are formed of cutting a planar sheet of synthetic resinous material to form flat bristles attached to a base, the base being in turn attached to an outer surface of a rotating drum member to permit convenient replacement.
