ABSTRACT:
Disclosed is a power brush for a vacuum cleaner by which dust is easily sucked into the vacuum cleaner with reduced noise and which can be easily manufactured. A brush body sucks dust by making contact with a floor. The brush body is provided at an end of a rigid wand which is connected to a vacuum cleaner body. A bottom portion of the brush body is open so that an air is introduced therein. A rotatable roller is provided at the bottom portion of the brush body. A pair of driving fans for generating a rotational force to rotate the rotatable roller are provided at both sides of the rotatable roller. The driving fans are driven by a dustless air which is introduced into the brush body through the air inlet holes which are formed at the front of the brush body.
