ABSTRACT:
High velocity exhaust air from within a vacuum cleaner is directed radially outwardly from a motor-driven impeller into a first duct. A second duct is provided that includes an effective large area opening for permitting exhaust air to diffuse quietly to the external atmosphere. A valve arrangement is provided for interconnecting the first duct alternately to a hose receptacle opening in which an outlet hose may be placed, or to the second duct to ensure especially quiet operation of the vacuum cleaner. The valve arrangement may comprise a chamber in flow communication with the first duct and having two, alternate outlets: the hose receptacle opening and a second opening leading into the second duct. A hinged door may be utilized for normally blocking the hose receptacle opening, but which is moved into sealing relation with the second opening simply by insertion of an end of an outlet hose into the hose receptacle opening.
