Vacuum leaves visible debris on carpets even after multiple passes

Safety: Remove the battery before inspecting the nozzle.

• Inspect brush roll: Check that bristles are not worn down or missing. Replace the brush roll if bristles are flattened or uneven.
• Clean nozzle channels: Remove the brush roll and clean the internal air channels of the nozzle.
• Use correct mode: Ensure the vacuum is set to the appropriate power mode and brush setting for carpets.
• Check suction and filters: Verify that suction is strong and filters are clean. Replace filters if needed.
