Abstract: A vacuum cleaner includes a first housing defining a cyclonic airflow chamber and a second housing defining a main suction opening that is in communication with an inlet of the cyclonic chamber. A suction source has a suction airstream inlet in communication with an outlet of the cyclonic chamber, and establishes a suction airstream that enters said main suction opening, passes through said cyclonic chamber, and passes to an outlet of said suction source. A substantial portion of particulates entrained in the suction airstream are separated therefrom when said suction airstream moves in a cyclonic fashion through the cyclonic chamber.

Abstract: An upright vacuum cleaner includes an upright housing section and a nozzle section. A cyclonic airflow dirt and dust separating chamber is defined in said upright housing section. A suction source pulls air and entrained dirt, dust, and other contaminants through a main suction opening formed in the underside of the nozzle and into the cyclonic airflow chamber. The cyclonic airflow chamber causes the suction airstream to travel in a cyclonic path such that the entrained contaminants are separated therefrom and deposited into a dirt container that defines the chamber. A main filter element filters residual contaminants from the suction airstream between the chamber and the suction source. The main filter element is preferably made from high-density polyethylene porous filter media.

Abstract: A bagless canister vacuum cleaner includes a selectively removable dirt cup, and an airstream flows rotationally through the dirt cup between an interior wall of the dirt cup and a filter assembly selectively mounted in the dirt cup so that entrained contaminants are separated from the airstream flowing through the dirt cup and collected by the dirt cup. The filter lies substantially parallel to the support surface on which the vacuum cleaner is supported. A cover member is connected to the main housing, and the cover member is selectively movable to and held in an operative position in covering relation with an open first end of a dirt cup. The main housing defines a base conformed to self-support the main housing on a support surface with the dirt cup arranged with its open first end at a higher elevation than its closed second end. The removable dirt cup includes a handle adapted for being held by a user, and the dirt cup defines or includes a spout to facilitate emptying dirt therefrom.

Abstract: An airflow indicator for a vacuum cleaner includes a housing, a wheel chamber defined in the housing, and a rotatable wheel mounted in the wheel chamber. The wheel has protrusions which cause the wheel to rotate due to inlet air flow. The wheel further has markings which gradually increase in size along an outside perimeter of the wheel. The markings indicate movement of the wheel. An air inlet is formed adjacent a first end of the housing. An air passageway is formed within the housing adjacent the rotatable wheel and the air inlet. The air passageway is curved to facilitate air flow along the protrusions of the wheel. A valve is mounted within the housing adjacent the air passageway. The valve has a cross slit which opens in response to a change in vacuum pressure. An air outlet is formed in the housing. A window portion partially encloses the wheel within the wheel chamber. The window allows viewing of the wheel from outside of the housing.
