发明名称 Duster having a rotatable vacuum pick-up
摘要 A hand-held device for dusting a surface is disclosed. The device includes al housing, a drive motor associated with the housing, a rotating dusting element rotated about its axis by the drive motor, and at least one conduit for removing dust from the dusting element. The conduit has a first portion for attachment to a source of vacuum and a side portion extending parallel to the axis of the duster and adjacent to the duster. Optionally, the first portion of the conduit is adapted to couple to a vacuum cleaner hose to draw air and debris into the side portion and out of the first portion of the conduit. The side portion of the conduit has one or more vacuum inlets extending along the duster for drawing dirt from the duster. One or more vacuum inlets are selectively rotatable from a first position generally facing toward the duster to a second position generally facing away from the duster and providing access to the vacuum inlet independent of the duster. The device weighs less than five pounds.
