The Hoover Platinum Lightweight Upright removes more dirt in one pass than other uprights. The lightweight design (less than 12 lbs) is easy to maneuver and transport upstairs or from room to room. With direct air flow technology and Hoover's patented Windtunnel Technology, it makes it easy to remove even hidden dirt. The HEPA filter bag traps 99.97% of dirt, dust, and pollens for better indoor air quality. There is even a bag check indicator to tell you when to change the bag.
