Abstract
A surface treating appliance includes a surface treating head, a hose, and a fan unit for generating a flow of fluid. A flexible duct assembly has a first end and a second end moveable relative to the first end between a first position allowing fluid flow between the hose and the fan unit, and a second position allowing fluid flow between the surface treating head and the fan unit. The duct assembly is connected to a first support which is pivotable about a first axis, and to a second support which is pivotable about a second axis spaced from the first axis. A drive mechanism effects the pivoting movement of the supports about their axes to move the second end of the duct assembly between the first and second positions.
