Carpet cleaner is very loud or makes grinding noises during operation

Safety: Unplug the unit before investigating noises.

• Isolate the source: Run the unit briefly (if safe) and listen whether the noise comes from the motor area or brush head.
• Inspect brush head: Remove the floor nozzle and check for stones, screws, or hard objects trapped near the brush or wheels. Remove any foreign objects.
• Check fan area: With the housing open (unplugged), inspect the suction fan for broken or rubbing blades. Replace the motor assembly if the fan is damaged.
• Tighten fasteners: Ensure all motor mounts and housing screws are tight to prevent vibration noise.

Persistent grinding or high-pitched squealing usually indicates failing motor bearings and requires motor replacement.
