When we started having problems with our Dyson dc17 vacuum I went on You Tube to see if anyone had the same problem. They suggested it sounded like a brush roll and gave instructions on how to remove and replace it, it seemed simple enough and it was. Three screws need to be unscrewed, the cover is removed, the brush roller is removed and the drive belt is removed. Check the belt, if it looks worn, replace with the new belt that comes with the order, then thread the brushroll through the belt and return it to its original position, with the curved side down and flat side towards you, tighten the cap and you're done. Checking took longer than changing the brush.
