Cleaning appliance
First Claim
1. A canister type cleaning appliance comprising:
- a separating apparatus for separating dirt from a dirt-bearing fluid flow;
a floor engaging rolling assembly comprising a fan enclosed within the floor engaging rolling assembly for drawing the fluid flow through the separating apparatus;
a chassis connected to the rolling assembly; and
a duct comprising an outlet section releasably connected to the rolling assembly for conveying the fluid flow to the separating apparatus such that the fluid flow flows in a fluid flow direction from the outlet section toward the separating apparatus, and an inlet section connected to the chassis for pivoting movement relative to the outlet section and the chassis as the cleaning appliance is maneuvered over a floor surface during a cleaning operation,wherein the outlet section is located external to the rolling assembly, the separating apparatus is located external to the rolling assembly, the outlet section is located between the separating apparatus and the rolling assembly during the cleaning operation, and the fluid flow flowing though the cleaning appliance during the cleaning operation flows through the inlet section, then through the outlet section, then through the separating apparatus, and then through the rolling assembly.

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.
