(This review was collected as part of a promotion.) This is the worst vacuum I've ever purchased. It just spits the dirt backwards at you as you attempt to clean, it doesn't matter what surface or speed it's on. I always have to sweep up hard floors after using it because the dirt is thrown at me and I've been using my old Dyson for carpeted areas because this vacuum only picks up half the dirt. The parking break doesn't work and there is always a dirt pile left under the vacuum on the floor where it is resting.
