Abstract
An upright steerable vacuum cleaner comprised of a handle, body, nozzle base and air duct therein further having a swivel joint at the junction of the nozzle base and body. The swivel joint or steering mechanism comprises a trunnion pivotably connected to the main air duct of the vacuum. The pivotable connection causes the nozzle base of the vacuum to turn right with a clockwise twist of the vacuum handle and turn left with a counter-clockwise twist of the vacuum handle. A locking mechanism is provided for preventing rotation of the trunnion with respect to the air duct.
