- the brushes are easy to fit, but when I switched on the vacuum there was a noticeable noise from the newly installed brushes. The problem is that the centering pin for one of the brushes is not properly centered, causing the brushes to align so they rub against the body. I checked if I can "adjust" the center pin, but nothing could be adjusted. . I compared the old brushes (OEM) and they are centered just right. The reason for replacing the brushes was that many of the OEM brushes were either worn out or missing. Unfortunately I cannot recommend this product.
