I have purchased the Bissell lift off revolution pet vaccum and have had it for about two years. I have to say that I love this vaccum. It has a detachable canister that i use when cleaning out my cars. I don't have any stairs but if I did it would work great. I have now three dogs, yellow lab puppy, black lab little older puppy and jack russell terrier. All shedding very bad right now with the change of season. I have a large home with wall to wall carpet. It takes me half the time to vaccum my home with my bissell than it did with my other vaccum. I have to empty the vaccum once, which is great...
