The invention provides an upright vacuum cleaner with a swivel and swing handle fitted to the upper end of the upright portion of the vacuum cleaner using a ball and socket joint and a connecting bolt. Because of the ball and socket joint and a spiral spring surrounding the connecting bolt between the ball and socket joint and the upper end of the upright portion of the vacuum cleaner, the handle can freely swivel and rotate at any angle relative to the upright portion to provide enhanced flexibility in maneuvering the vacuum cleaner, thus effectively reducing the bodily stress and strain involved in using a vacuum cleaner.
