Abstract
A dust collector is disposed between an intake port and an exhaust port in a vacuum cleaner. Air flows from the intake port into the exhaust port along an airflow path in the dust collector. The dust collector includes a dust-collecting net disposed in the path, and a dust-brushing unit. When air flows from the intake port into the exhaust port, a plurality of dust brushes of the dust-brushing unit rotate to brush the net so as to remove dust from the net. Therefore, air can flow unimpeded through the net.
