发明名称 SURFACE TREATING APPLIANCE
摘要 <p>A surface treating appliance, such as a vacuum cleaner (1), comprises means for generating a flow of fluid in the form of a motor and fan, housed in a main body (2). A hose and wand assembly (3), a surface treating head (10) and a rotary change over valve (42) are also provided. The valve (42) is selectively rotatable so as to allow fluid flow from either the surface-treating head or the hose. A support assembly (14) is moveable between a supporting position, in which it supports the main body (2), and a retracted position. The change over valve (42) and support assembly (14) are arranged so that motion of the support assembly between the supporting and retracted positions induces rotary motion of the change over valve.</p>
