I purchased 3 different vacuum cleaners - Shark, Hoover and something else? I was so tired of broken parts and no sucking power. I did my research and finally decided to purchase a Dyson DC25 and my carpet is finally clean!!!! The sucking power is great --- even with cat hair and dog hair. It was easy to assemble and lightweight. However, the best part of this vacuum cleaner is that it is easy to handle in tough spots such as under tables and on the side of the walls. Prior to my Dyson purchase, I had nightmares about vacuuming ... now I actually enjoy it! And with the prices offered by Overstock.com --- you can't deny yourself the excellent performance of a Dyson!
