Brush roller spins intermittently or stops when pressed against the carpet.

Safety first: Unplug the machine before working on the brush head.

• Clean brush ends: Remove the brush roller and clean hair and fibers from the end caps and bearings.
• Inspect belt tension: Check the drive belt for glazing or stretching. If it slips easily on the pulleys, replace it.
• Adjust brush height (if adjustable): Set the brush height adjustment to a higher setting to reduce load on thick carpets.
• Check motor torque: If the belt and brush are good but the brush still stalls easily, the brush motor may be weak and require replacement.
