Rug Doctor carpet cleaner brush does not rotate, but suction and spray work normally.

Safety: Unplug the unit and lay it on its back to access the brush area.

• 1. Inspect belt: Remove the bottom plate and check the brush drive belt. If broken or off the pulley, replace and correctly route the belt.
• 2. Check brush rotation: With the belt removed, spin the brush cylinder by hand. If stiff or seized, replace the brush assembly.
• 3. Test brush motor: On models with a separate brush motor, check wiring connections and test motor resistance. Replace the motor if open or shorted.
• 4. Verify mode selection: Ensure the machine is not in a transport or tool-only mode that disables the main brush.
