The main purpose in getting a new vacuum was because my old vacuum wasn't picking up all the animal hair. I was told by a "vacuum guy" that I only needed to get my old vacuum serviced properly, however, I felt it was time for a bigger and better one. When selecting the new one I clearly saw that this vacuum had many more bristles in the beater brush than others I could have chosen. When I got it home and turned it on, I was very impressed. The hair left behind by the old vacuum was easily taken care of by this new one. In addition, I now have attachments that work on upholstery, stairs and corners. Definitely a great purchase!
