If you notice that your Bissell equipment is either not working or not working as well as it was, it may simply need cleaning, or it may need a component replaced. For example, in a Bissell vacuum, a clogged brush roll may simply need to be cleaned out in order to keep it spinning. But if you notice damage to the brush roll or another part of the vacuum you might want to get that part replaced, especially if it is causing issues with your vacuum. Another thing to consider is elements like the hoses on your vacuum, small holes or cracks can greatly effect vacuum efficiency. If you notice these issues, you might need replacement hoses.
