Dust Ball

Powered by a compact version of the 4.8-volt battery in Black & Decker’s big hand vacs, this grapefruitsize model is made to sit on your desk or workbench, ready to sweep up crumbs or sawdust. Its handle and nozzle flip out at the press of a button and then fold back into the sphere so it can snap into a charging cradle.
