Robot vacuum is very loud during operation, with increased whistling or roaring noise from the suction area.

Safety first: Turn OFF the robot and remove it from the dock before servicing.

Restore airflow:

• Remove and empty the dust bin.
• Disassemble any internal cyclone parts and clear dust clumps.
• Remove and clean or replace the primary and HEPA filters.
• Inspect the suction inlet behind the main brush for lodged objects and remove them.

Test noise level:

• Reinstall all parts and run the robot. If the noise is significantly reduced, the issue was airflow restriction.

Advanced: If the noise remains very high, with grinding or rattling sounds, the suction motor bearings may be worn. Replacing the suction motor/fan assembly requires opening the robot and should be done by a technician.
