If your Dirt Devil isn't cleaning efficiently or the brush roll is stuck or not spinning, there may be a few reasons why. Unplug the vacuum and inspect the brush roller. If there is any debris or hair stuck around the brush roller or inside the housing, try to clean it out to keep the vacuum working.
If the vacuum isn't clogged, make sure the belt is connected to the roller and to the drive motor pulley. A broken belt will not be able to spin the roller at all and need to be replaced. If the roller is damaged and incapable of spinning, you'll need to replace it.
