You will be amazed how much your previous vacuum has missed once you start using this wonder. We have two cats and three dogs-a golden retriever and border collie who are shed machines-and I seemed to be constantly chasing hair tumbleweeds. The first time I used the vacuum on my 9x7rug, I had to empty the canister twice. That would have been two bags with the last vacuum. Not only is our house now cleaner but our wallet a little fatter as we are not buying two boxes of bags a month. Plus the benefits for the upcoming spring allergy season. I love this vacuum.
