Machine for removing dust from air

Dust can be attracted to a surface by a static electric charge. This property could be used to remove dust from the air. The device would charge a surface, attracting dust, then discharge the surface. The surface could then be washed with water to remove the dust. The water could be filtered and then reused. Applying a superhydrophobic coating to the surface would allow optimum cleaning of the surface and hence aesthetic appeal.
