PURPOSE: A brush of vacuum cleaner for mopping cleans a floor by using suction power of a fan motor, and a connecting tube(150) reduces vibration to a vacuum cleaner. CONSTITUTION: A brush of vacuum cleaner for mopping consists of a base plate(110), an eccentric cam(120), a driving fan(130), a cover(140) and a connecting tube. The eccentric cam(120) on the top of the base plate(110) spins with a bearing. The driving fan(130) is fixed with the eccentric cam(120) to spin together. The suction power of a fan motor drives the driving fan(130) and the eccentric cam(120). Spinning of the eccentric cam(120) causes vibration of the base plate. The duster(101) on the bottom of the base plate(110) also vibrates, cleaning a floor. The duster is attached and detached with a Velcro tape(102). The connecting tube is designed for reducing vibration from the base plate(110) to a vacuum cleaner as corrugated shape. Therefore, a user comfortably uses the vacuum cleaner to get rid of not only dust in the air but also dirt on the floor.
