Hi, it's Allie from Crucial Vacuum!
There are a few potential solutions you should try. Start by checking your unit's brushroll and clear it of any tangled hair strands or debris that my be blocking the airway. You can carefully use a pair of scissors to do cut and remove anything that is tangled and may prevent the roller from running.
Your unit's brushroll is connected to the motor by belts. Over time, the belt's wear down and stretch out losing the grip and tension that turn the roller. Ideally, belts should be replaced every 3 to 6 months.
Follow by checking the internal hose for any blockages.
If the roller brush is still not working, the problem could be caused by a lack of suction. Washable filters should be washed frequently after every 1 or 2 uses or at least once a month, and replaced every 3 to 6 months for optimal performance. Non-washable filters, should be also replaced every 3 to 6 months to keep your unit running properly.
