The last three vacuums I've owned were dysons. Never again! This bissell vacuum is by far the better vacuum!! I have 4 large dogs and my new bissell is sucking up so much dander that my "previous" vacuums left behind!! I was actually shocked at what was still in my carpets!! And the price!! A fraction of what I've paid for the other brand!! I will never buy anything but bissell from now on!!
