This vacuum cleaner doesn't do what it's supposed to, picking up dirt from floors and storing it for recycling. The small plastic door seal breaks down almost instantly, allowing dirt, sand or other small debris to fall back onto the floor during cleaning. You must be careful and constantly empty. All of these are really good for removing dog hair and dust. Well it's a joke. How did it pass a test? Shark should be ashamed to sell this. What a waste of money.
