I got this out of the box, assembled it, and used it in my living room. But before I used it, I vacuumed my living room with my old cleaner and that yielded no dirt in the Hoover wind tunnel cannister. Then, I used the Dyson Allergy and Asthma that I ordered from HSN...yep, you guessed it, it picked up 19 cannisters of dirt just in the living room and dining area of my 1 bedroom apartment and I used my old vacuum 2x a week.
