When I received my new Bissell Pet Hair Eraser Vacuum, I assembled it, which wasn't that difficult. I plugged it in, turned it on and OMG, I have never seen cat hair like that before. I have 3 cats! I had an Oreck XL and was frankly tired of having it serviced over and over. It seemed to work pretty well but again, it got to the point that it wouldn't pick up a loose string sitting on the carpet. I have vacuumed frequently and my carpet was pretty clean, so I thought. When I turned on the Bissell, the canister filled up almost immediately with the largest ball of cat hair I had ever seen in only about a 3 x 3 area. Needless to say, "gross"! Or another way to look at it, "Finally"! A vacuum that works as well as they said it would. I love the attachments that are specific for pet hair. I've only had it about 2 weeks and the difference is amazing. Cat ladies and gentlemen, we have a winner!
