I have the Bissell Lift Off too, and althought I LOVE the way it vaccuums, I did find a big downfoall of it. I have dogs in the house, so lots of dander and dog hair, and I find alot of it gets caught up around the filter area. I have to unscrew the plastic fileter holder where the foam filter is, and run my fingers up in there to pull all the trapped dust and dog hair out. I am seriously considering switching to the Dyson, as they advertise that with their design, this doesn't happen, because it is designed differently with nothing for it to get hung up in. The only reason I have not yet bought the Dyson, was because it was quite expensive(in comparrison to my Bissel for example, that works REALLY well otherwise), but the Dyson seems to be made with a more brittle type plastic housing, and I wonder how it will last??? Anyone know??
