Abstract: A nozzle assembly of a vacuum cleaner is disclosed. The A nozzle assembly includes a main casing having an air inlet formed thereto to draw in dust or dirt from a surface to be cleaned, a drum brush disposed in the main casing to brush away the dust or dirt adhered to the surface while rotating in contact with the surface, and a subsidiary brush unit disposed in front of the main casing to preliminarily brush away the dust or dirt adhered to the surface in front of the drum brush, and having a cover disposed in front of the main casing, and a subsidiary brush member to come in elastic contact with the surface. The subsidiary brush member is configured to change a relative position to the cover, and thus to selectively maintain a contact state or a non-contact state to the surface.

Abstract: A dust collecting container for a vacuum cleaner is removably mounted in a suction chamber of a cleaner body to filter a dust from a dust-laden air being drawn into the suction chamber through an air suction hole that is connected with the outside. The dust collecting container has a dust collecting casing having a connecting hole connected with the air suction hole and a discharge portion for discharging the drawn air, and a filter assembly having at least three filters, and removably mounted at the discharge portion. With the plurality of filters that respectively and consecutively filter from the largest to the most minute particles of the dust-laden air drawn in the dust collecting chamber, the dust collecting container is rarely blocked even for a long period of use.
