<p>A hand held rotary duster for dusting surfaces is described. In one embodiment the device includes a housing (1), a drive (14,17), a generally cylindrical rotating duster (20), and a conduit (7-9). The housing is axially elongated and has a first end, a second end, and a center section. The drive is associated with the housing. The dusting element is a generally cylindrical rotating duster having a first end, an axially spaced second end, and an axis of rotation, its first end being coupled to the drive. The conduit extends at least substantially from the first end of the housing to the second end of the duster. The conduit has an inlet and an outlet. The duster optionally includes a reduction drive arrangement that reductively couples the drive motor to the duster. The duster optionally includes a generally planar surface extending from the housing and in frictional contact with the duster and a vacuum port in the generally planar surface for removing dust from the dusting element. The device weighs less than five pounds.</p> |
