Thank you for your question.
â€¢ This model of vacuum does not have a belt drive floor roller brush. It has a direct drive motor assemble. So there is no need to access this area. However if you choose to examine the roller brush area, follow the next steps as listed.
â€¢ The first thing to check is to push the red reset overload protector button on the base assembly. If you have already done that, make sure you have the extension hose properly docked onto the base unit.
â€¢ If you want to get into the lower brush roller assembly you will need to turn the unit over the there are 10 screws on the under side to remove the roller brush bottom cover. Before removing the cover, turn vacuum right side up and release the handle and lower all the way down.
â€¢ Now you should be able to access the roller brush area, to examine for any service issues and air flow blockages.
If you do not feel confident repairing this problem yourself, then you can have it repaired by a Sears technician. Here is a link that will provide the nearest drop-off locations:
