Cut dusting time in half with the revolutionary motorized Hurricane Spin Duster that uses static electricity to pick up dust like a magnet. The secret is thousands of electrostatically charged bristles that attract and trap dust. Just press the button, and it spins into action. It's the easiest way to dust bookshelves, blinds, fixtures, crevices, corners and other hard-to-reach places. Requires 4 "AA" batteries (sold separately). Plastic, metal. The set includes 2 duster heads, and an extension handle. Reaches up to 34".
