Robot vacuum leaves visible dust and debris on the floor; cleaning performance is poor even though it runs normally.

Safety first: Turn OFF the robot and remove the dust bin.

• Empty dust bin: Completely empty the bin and clean internal surfaces with a soft brush.
• Clean or replace filters: Remove the primary and HEPA filters. Tap them gently to remove dust. If they are discolored or older than the recommended replacement interval, install new Honiture Dust Bin Filters.
• Inspect suction inlet: Turn the robot over and check the suction opening behind the main brush for blockages. Remove any lodged debris.
• Check fan noise: Start a cleaning cycle and listen for the fan. If it sounds unusually quiet or rough, the Vacuum Fan Motor may be partially obstructed and should be cleaned or replaced.
