ABSTRACT:
A locking unit of a brush assembly for use with a vacuum cleaner has a release preventing member so that if the brush assembly accidentally falls, the release preventing member conveniently keeps upper and lower housings of the assembly assembled. The brush assembly includes the upper and lower housings. A connector is secured in one of the upper and lower housings and is adapted to direct air in the upper and lower housings towards a suction force generator of the vacuum cleaner. A locking unit rotates on the connector to open and sealingly close the upper and the lower housings. The release preventing member is formed between the connector and the locking unit to prevent release of the locking unit.
