UPRIGHT VACUUM CLEANER WITH AIR FLOW SWITCH

摘要

A surface treating appliance (10) includes a surface treating head (12), a hose (52), and a fan unit (57) for generating a flow of fluid. A flexible duct assembly (122) has a first end (124) and a second end (126) 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 (142) which is pivotable about a first axis (PI), and to a second support (144) which is pivotable about a second axis spaced from the first axis. A drive mechanism (180, 184) 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.
