Abstract
The present invention provides an upright vacuum cleaner () having an elongate body () and comprising a floorhead () on which the elongate body is mounted, the floorhead () having a first inlet () for dirty air, a wand having a second inlet for dirty air, a changeover valve () for selecting between a flow of dirty air from the first or second inlet, a dust collection chamber () also having a dirty air inlet (), a duct () for conveying said flow of dirty air from the changeover valve () to the dust collection chamber inlet (), and a source of suction power for drawing the dirty air from the first or second inlet through said changeover valve () and said duct () to the dust collection chamber inlet (). The changeover valve () comprises a linear conduit () positionable in fluid flow between the first inlet () for dirty air of the floorhead () and said duct (), the duct () having a sigmoid curve () from the changeover valve () to the dust collection chamber inlet (). When the conduit () is positioned in fluid flow between the first inlet () and the duct (), the flow of dirty air from the first inlet (), through the changeover valve () and the duct () to the dust collection chamber inlet () all lies in a plane.
