CleanMax 6-Qt. Backpack - This is a CleanMax 6-Qt. Backpack. When a traditional vacuum just won't do, the CleanMax Backpack will. With an ergonomically designed shoulder harness and belt, the Backpack makes it easy to clean on, around and in between furnishings. Despite the quite motor, cleaning is powerful enough to move embedded dirt, whether it's on hard floors, carpet, ceilings, or furniture.
