Abstract
The vacuum cleaner having a suction port assembly and a dust collecting chamber includes a first air inlet path to connect the suction port assembly and the dust collecting chamber, a second air inlet path to connect a lower end of the dust collecting chamber and a vacuum generator, a cyclone dust collecting device detachably mounted in the dust collecting chamber so that an upper end is connected to the first air inlet path and a lower end is connected to the second air inlet path, and a filtering chamber integrally formed with the cyclone dust collecting device and having a filter member detachably disposed. As the second air inlet path requires less space, it is feasible to easily manufacture the vacuum cleaner and maintain the filtering chamber and the cyclone dust collecting device at a time. Therefore, maintenance of the vacuum cleaner becomes more convenient.
