摘要： 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.
