ABSTRACT:
A dust collecting unit of a vacuum cleaner has a dust collecting body including a first dust separating unit for separating dust from air and a first dust storing unit for storing the separated dust. A cover member is coupled to the dust collecting body and a second dust separating unit for further separating dust from the air is formed in the cover member. A second dust storing unit for storing dust separated by the second dust separating unit is formed in the dust collecting body. A dust passage for guiding the dust separated by the second dust separating unit to the second dust storing unit is also provided on the dust collecting body.
