WOW!! After seeing the Dyson commercial on TV, I could relate, I too was frustrated with my former vacuum cleaner losing suction. What's more, I hated having to clean my bagless vacuum every time after cleaning my house. When I got my new Dyson home, I did a little test just like the salesperson suggested, I vacuumed my carpets with my old vacuum cleaner and then I tried my new Dyson. I was shocked by the amount of dirt the Dyson picked up.
