Abstract
A vacuum cleaner includes a housing, a nozzle for picking up dirt and debris, and a vacuum generator. The vacuum generator includes a motor and drive shaft, a first fan connected to the drive shaft, a shield including a recess that functions as an air induction chamber for receiving the fan, and an air inlet port formed in the shield. A pathway provides fluid communication between the nozzle and the vacuum generator. A dirt and debris collector in the form of a dust bag is provided in the pathway between the nozzle and the vacuum generator. The vacuum cleaner also includes an infuser that is carried on the shield about the air inlet port. The infuser directs air into the induction chamber in a more efficient manner to improve vacuum cleaner performance.
