Abstract:
A vacuum cleaner comprising:a base;a substantially upright elongate body portion having a longitudinal axis and including a handle portion and an air duct;a substantially spherically shaped trunnion pivotally attached to said base about a substantially horizontal pitch axis, said trunnion defining an air channel capable of facilitating the flow of air from said base to said air duct within said body portion;a link assembly for linking said trunnion to said air duct such that said body may be rotated about said longitudinal axis while pushing said vacuum by twisting said handle in a clockwise or counter-clockwise direction causing said base to veer right or left depending on the direction in which said handle is twisted; anda steering lock slidingly mounted in the base such the steering lock selectively engages the trunnion and the air duct, barring the handle twisting motion from turning said base.
