Abstract
A filtration arrangement of a vacuum cleaner includes a floor-engaging base unit, a body portion pivotally mounted on the base unit and a suction motor/fan assembly located in either the base unit or body portion. A dustcup is mounted on the body portion and is in fluid communication with a first air path so as to receive dirt laden air therefrom. A cyclonic member is disposed over the dustcup and is effective for imparting rotational motion to the dirt laden air entering the dustcup. An air tube is mounted centrally within the dustcup and extends from the bottom of the dustcup to an area near the top of the dustcup. A removable filter member is disposed over the top portion of the air tube. The removable filter has a central opening that cooperatively engages the top portion of the air tube to establish a second air path that extends from inside the dustcup to outside atmosphere through the suction motor/fan assembly.
