Abstract: A vacuum cleaner that includes a first dirt-separation stage, a second dirt-separation stage, and a vacuum motor for moving air through the first dirt-separation stage and the second dirt-separation stage. The vacuum motor has a centrifugal impeller driven by an electric motor. The first dirt-separation stage is then located upstream of the impeller, the second dirt-separation stage is located downstream of the impeller, and the second dirt-separation stage has a plurality of cyclonic separators that are arranged around the vacuum motor.

Abstract: A vacuum cleaner having a main body and a dirt separator that is removably attached to the main body. The dirt separator includes a first dirt-separation stage, a second dirt-separation stage, and a vacuum motor for moving air through the first dirt-separation stage and the second dirt-separation stage. The vacuum motor has an impeller driven by an electric motor. The first dirt-separation stage is then located upstream of the impeller, and the second dirt-separation stage is located downstream of the impeller.
