Abstract: A suction brush assembly comprises an assembly body having a suction inlet for drawing in dust on a surface being cleaned, a cover connected to the assembly body and having an opening for drawing in an external air, and a rotation body rotatably mounted to the assembly body and mounting a detachable cleaning member at a lower part thereof for contact with the surface being cleaned. The external air drawn in through the opening flows out to a lower part of the assembly body through a gap formed between the rotation body and the assembly body. Accordingly, the dust can be prevented from flowing into the rotation body, thereby improving an efficiency of a cleaning work.

Abstract: A brush assembly and the vacuum cleaner using such a brush assembly comprises a brush main body having an air suction opening and a turbine chamber, a turbine mounted in the turbine chamber and having an air passage, and a connecting pipe connecting a vacuum cleaner main body with the brush main body, the turbine being mounted only within a portion of the air passage. Accordingly, a brush connected with the turbine can efficiently be operated, and unpleasantness to the user caused by noise generated during cleaning can be reduced.
