Abstract
A vacuum cleaner with a vacuum unit and a wand assembly. The vacuum unit has a vacuum unit inlet. The wand assembly has a rigid portion and a flexible portion. The rigid portion has proximal and distal wand ends, and is reconfigurable between a condition in which the proximal wand end is rigidly connected to the vacuum unit inlet, and a condition in which the proximal wand end is movable relative to the vacuum unit inlet. The flexible portion has a proximal hose end to connect to the vacuum unit inlet, a distal hose end configured to fit inside the rigid portion, and a flexible hose between the hose ends. The hose is movable between a condition in which the hose is entirely inside the rigid portion, and a condition in which at least a portion of the hose adjacent the proximal hose end extends outside the rigid portion.
