Patent abstract
A vacuum driven light bulb changer. The device has a power source that energizes an electrical circuitry so that when the power switch is activated it energizes a motor that activates a vacuum pump. The activation of the vacuum pump draws air into the intake head on the vacuum cup. When the vacuum cup is place firmly against the outside surface of a light bulb, the vacuum creates a depressurized zone against the outside surface of the light bulb and the inside bottom surface of the vacuum cup allowing the turning of the light bulb.
