  • Patent number: 6598263
    Abstract: A dirt collecting system for a vacuum cleaner includes a dirt cup formed with a coarse particle separation chamber and a fine particle separation chamber separated by an apertured wall. Coarse dirt particles directed into the coarse particle separation chamber are prevented from entering the fine particle separation chamber by the apertured wall. The apertured wall is removable from the dirt cup and is cleaned upon removal by a cleaning element. A fine particle filter is located in the fine particle separation chamber for filtering fine particles. The fine particle filter is cleaned by rotating a knob located in the dirt cup lid so that the pleats of the fine particle filter is brushed past a wiper element.

  • Publication number: 20020166199
    Abstract: A dirt collecting system for a vacuum cleaner includes a dirt cup formed with a course particle separation chamber and a fine particle separation chamber separated by an apertured wall. An inlet opening is formed in the dirt cup and communicates with the course particle separation chamber for inputting a stream of dirt laden air into the course particle separation chamber. A clean air outlet opening is formed in the fine particle separation chamber for allowing the filtered air stream to exit the dirt cup. The apertured wall includes a pre-filter for filtering coarse particles from a stream of dirt laden and depositing the coarse particles in the course particle separation chamber. A fine particle separation filter is positioned within the fine particle separation chamber and communicates with the clean air outlet opening. The fine particle separation filter separates fine particles from the air stream and deposits the fine particles within the fine particle separation chamber.
