• Self-empty suction weak: Check the robot bin flap, base intake, dust bag, and base filter.
• Brushroll error repeats: Replace worn brushes, damaged end caps, or clogged filters as needed.

Odor, Noise and Airflow Problems

• Bad smell: Empty the dust cup, wash filters, remove trapped pet hair, and let all washable parts dry completely before reassembly.
• Whistling noise: Check for air leaks, missing filters, loose dust cup, or partially blocked hoses.
• Loud rattling: Inspect the brushroll, nozzle, hose, wand, and dust cup for hard debris or broken parts.

Filter Cleaning and Maintenance Problems

• Filters still dirty: Rinse washable filters with water only until the water runs clear.

• Maintenance light remains on: Clear all blockages, wash or replace filters, empty the dust cup, then restart the vacuum.

Routine Maintenance Tips

• Empty often: Empty the dust cup or robot bin after each use or before debris reaches the max fill line.
• Clean filters: Wash washable filters on the schedule recommended in the manual and replace worn filters when needed.
• Inspect brushrolls: Remove hair, thread, carpet fibers, and pet fur from brushrolls, rollers, end caps, and side brushes.
• Check clogs: Inspect hose, wand, nozzle, dust cup inlet, robot suction path, and self-empty base regularly.
• Store correctly: Store cordless vacuums on the dock or wall mount and keep robot docks powered in an open area.

Safety note: Always turn off and unplug the vacuum, remove the battery, or place the robot in standby before clearing blockages, cleaning brushrolls, washing filters, or servicing accessories. Never reinstall wet filters, operate with missing filters, or use a damaged cord, battery, charger, hose, or nozzle.
