The invention relates to an electric vacuum cleaner having means to remove dust that is trapped in a filter that traps fine dust. Switch means switches air passages to provide communication between an auxiliary air passage and the suction side of an electric blower with fine dust removed from a pleated filter by a rotating body being received by a dust receiving section. Air is sucked from an outside-air intake opening into the electric blower through the dust receiving section and a fine dust filter in a dust collecting section unit, which allows the fine dust collected in the dust receiving section to be trapped in the fine dust filter, resulting in improved cleanliness.
