I bought two of these, because I loved the power nozzle on a lightweight vacuum. It really did an excellent job picking up fine hair and dirt on carpets and floors; however, after using it a while, the power nozzle started to scream then finally stopped working altogether. The filter is dirty to handle as everything sticks to the fabric, I think making a bag for it would be more sanitary. It is an excellent idea, and I'm really sad they broke down, because I love the machine, but it needs a lot of improvements. I would buy another one if Hoover improved this machine and made it to last.
