The belt may be broken
If the belt snaps the brushes underneath the cleaner will not spin round and sweep up debris from the floor. Switch the product on, tip to one side and carefully look to see if they are rotating. If they are not then it is probable that the drive belt or rubber band has broken. Also if there is a large amount of debris tangled up around the brush that may stop the cleaner from picking up effectively. Hoover recommend that you replace the belt and brush assembly once per year, replacements can be purchased from the spares section on the web site.
