Hey, this is Leland with Crucial Vacuum,
If the brush bar is not working properly there may be several reasons.
Firstly, the motor may be the problem. If you hear any noises while the machine is running, you should contact the original manufacturer for
trouble shootingsolutions.
Secondly, your vacuum may be in need of new parts. By changing either the brushroll or belts, you should be able to increase the quality of the suction.
