ABSTRACT:
A brush head assembly for a vacuum cleaner having an improved structure. The brush head assembly has a brush head body having a triangle structure including a vertical plane to which an upholstery brush is attached, a lower plane horizontally which is formed at a lower portion of the vertical plane and having a dusting brush attached thereunder, and an inclined plane which is formed between the vertical plane and the lower plane, has a connecting pipe integrally formed on the inclined plane of the brush head body and extending upward at an angle of 90 degrees with respect to the inclined plane, and a neck pipe having a front end portion having a hemisphere shape which is inserted into the connecting pipe, a rear end portion which is inserted into an extension bar, and an inlet hole which is formed below the hemisphere shaped front end portion. The brush head body is rotatable about the neck pipe so that the vertical plane and the lower plane alternately make contact with a floor as the brush head body rotates. The brush head assembly for a vacuum cleaner can be used at various places to be cleaned without changing the brush assembly, so cleaning efficiency is improved.
