Abstract
A cleaning appliance includes separating apparatus for separating dirt from a dirt-bearing fluid flow, a floor engaging rolling assembly housing a motor driven fan unit for drawing the fluid flow through the separating apparatus, a chassis connected to the rolling assembly, and a duct for conveying the fluid flow to the separating apparatus. To improve the stability of the appliance, the duct has an inlet section which is connected to the chassis for pivoting movement relative to the chassis as the appliance is maneuvered over a floor surface. An outlet section for coupling the inlet section to the separating apparatus is releasably connected to the rolling assembly to facilitate the removal of any blockages within the duct.
