Robot vacuum runs but leaves visible debris on the floor, especially along its path.

Safety: Turn off the robot and remove it from the dock.

• Empty dust bin: Remove and empty the bin completely.
• Clean or replace filter: Remove the HEPA filter, tap out dust, or replace if old or damaged.
• Inspect main brush: Remove the main brush and clean hair and debris. If bristles are worn flat or rubber fins are cracked, replace the brush.
• Check suction inlet: Look into the suction opening for clogs and remove any obstructions.
• Test performance: Run a cleaning cycle and observe pickup. If still poor, the suction fan may be weakening and require replacement.
