I purchased this vacuum because I have a Labrador Retriever. I own the Shark Rotator 501 and wanted to replace it because it is older. When I received this vacuum I was so disappointed after years of a great vacuum. I ordered a new hose and filters for my old one at the same time. The power cord on this vacuum is way to short, the suction power is not as strong as the 501 and i like my OLDER model because of the separate floor attachment. Needless to say, I gave my sister this new vacuum as an early birthday present and I kept my older vacuum. I am going to order new parts for my older vacuum while they are still available and keep them for when things go wrong.
