I bought this vacuum to replace an Oreck that I had for years. I was pleasantly surprised! Its very powerful and easy to use. The Shark is lightweight compared to my old vacuum and I love all of the attachments.  Also, very important in my decision purchase,  was that it had an anti-allergen HEPA sealed system.  Plus, I bought it on sale for a fantastic price.  I just don’t know where to put the third attachment.
