I bought the vacuum and allergy kit and couldn't be happier or more amazed. How is it possible to vacuum thoroughly and yet, the next day, pick up so much dirt and hair? Yet, this vacuum does that. It thoroughly amazes me that my old vacuum, which I always swore by, didn't pick up all this dirt. As days progressed, I was picking up less and less dust and dirt and hair. When I didn't vacuum for two days, it was amazing to see how much had accumulated in such a short time. In short, I'm very satisfied.
