Using these Hoover vacuum cleaner brush drive belts is easy. First, make sure your vacuum is turned off and unplugged. Open the part of the vacuum where the old belt is located. Carefully remove the old belt and clean any dirt, hair, or fluff from the brush roller. Then, take one of the new belts from the pack and place it around the brush roller and the appropriate drive mechanism. Make sure it's properly seated and aligned. Close the vacuum back up and you're ready to go. As for maintenance, regularly check the brush roller for any build - up of hair and fluff. Remove this debris as soon as you notice it to prevent unnecessary strain on the belt. If you ever have any issues, don't worry as these belts come with a full guarantee.
