A shaving device includes an assembly to better maintain the cutting blades in contact with the skin during shaving. A swivel ball joint is preferably located between the shaver head and the housing and enables the head of the shaver to move in any direction from a longitudinal axis through the shaving device. A positioning spring connected to the ball joint and the housing is biased toward the center axis of the shaver and provides a swivel action that causes the shaver head to return back to its center position after adjustment of the head's angle. A motion transfer spring transfers the motor action to the upper shaving mechanism at any angle or direction that the shaver head may be in at any time. As the shaver head changes angles to match the contour of the user's body, the motion transfer spring flexes to follow the angles of the shaver head. This transfers the motion of the motor to the eccentric cam, which helps to control the motion of the trimmers. In order to prevent water from entering into the electrical parts of the shaving device, a water-resistant cap and a water-resistant O-ring can be utilized.
