I would give this unit five stars, I love the way it sucks but when I throw out the garbage it's very hard for me to take it apart to clean it. I have arthritis in my hands and each of these buttons requires two hands to push and pull at the same time. I would send it back for that alone, but I love vacuuming too much for that. Just be careful if you don't have a lot of power in your hands, it could break the deal. Oh, and the loading hole is hard to find on the handle.
