Abstract:

A light weight upright vacuum container including a cylindrical cyclonic air separation and dirt collect container with a combination shroud and pleated filter cartridge holder. The container has a tangential air inlet at the upper portion, a closed bottom and an open top leading to a motor positioned in the upper portion of the vacuum cleaner housing provide for improved air separation and dirt collection. The shroud has an open sidewall and a closed bottom with an outwardly and downwardly extending skirt that extends to the about the midpoint of the height of the container. Dirt particles that separate from the air flow above the skirt drop to the lower portion below the skirt. Clean air then exits an open upper portion of the shroud to the suction source above the container. The air exiting the shroud passes through a frusto-conical region and into a radially pleated filter before entering the vacuum motor.

Abstract:

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.
