Abstract:
A vacuum cleaner having a base with a: nozzle opening, rear housing attached to the base, dirt separator with inlet and outlet passages, vacuum fan, accessory hose, and valve system to connect the separator alternately to the nozzle opening and hose. The valve system has a valve body having a first inlet connected to the nozzle opening and a second inlet connected to the hose, a hose connector that pivots with respect to the valve body, a connector passage through the hose connector, and a flexible outlet hose having a first end connected to the connector passage and a second end connected to the separator inlet passage. The valve inlets are generally equidistant from the connector pivot and the hose connector is pivotable to rotate the first hose end relative to the second hose end to selectively place the connector passage in communication with the first and second valve inlets.
