Finally ultra-lightweight power is unleashed with the Zoom 800 Cordless vacuum. The hassles of winding and unwinding the cord are over thanks to the 44 volt lithium ion battery pack which keeps the Zoom running at top cleaning power for approximately 50 minutes. Check the remaining life of the battery with the press of a button, but don't worry about running out of cleaning time, simply swap out for a fresh battery or recharge in less than two hours. Keep the speed, lose the cord with the Zoom 800.
