The Dyson Anilmal vacuum cleaner is unbelievable! After I assembled it, I decide to vacuum the rug in the den that I vacuumed with my Oreck yesterday. The canister filled so quickly. I was impressed with the suction power but I was appalled that the Oreck had not been doing the job. I went on to clean all the rugs. I had to empty the canister numerous times.I recommend this product highly.
