STAUBSAMMELANORDNUNG UND DAMIT AUSGESTATTETER STAUBSAUGER

A dust collection unit (400) for a vacuum cleaner includes a first filtering chamber (423) filtering relatively large foreign objects, a second filtering chamber (424) filtering relatively small foreign objects when air exhausted from the first filtering chamber (423) is introduced into the second filtering chamber (424), an exhaust member (407) disposed above the filtering chambers to guide airflow, a storing chamber disposed under the filtering chambers to store the foreign objects filtered in the filtering chambers, a sealing member sealing bottoms of the filtering chambers, and a rectifying unit (463) formed on an exhaust side of the second filtering chamber (424) to rectify airflow, thereby reducing noise generated by the airflow.
