An upright vacuum cleaner includes a suction apparatus and a body pivotably mounted to the suction apparatus. The suction apparatus includes a suction opening and a rotatably driven dust agitator. The body includes a suction motor, support wheels, and a manually grippable handle. The body is swingable downwardly relative to the suction apparatus from an upright position to a normal use position, whereupon the height of a gap between the suction opening and a floor surface is minimized to promote effective cleaning. If the body is swung further downwardly past the normal use position, the height of the gap is prevented from changing, so the effective cleaning is maintained.
