Abstract
A dust collection unit for a vacuum cleaner includes a first filtering chamber filtering foreign objects using a cyclone airflow, a separation plate defining a top surface of the first filtering chamber, a filter having a diameter that is reduced as it goes downward in response to airflow rate variation in the first filtering chamber, and a blocking member provided under the filter to prevent the foreign objects filtered in the first filtering chamber from flying.
