Vacuum leaves visible dust and debris on carpets despite multiple passes.

Safety first: Remove the battery before inspecting the nozzle or brush roll.

• Step 1 – Inspect brush roll bristles: Remove the brush roll and check the bristles. If they are very short, soft, or unevenly worn, they will not agitate carpet fibers effectively. Replace the brush roll.
• Step 2 – Clean nozzle channels: Look inside the nozzle for dust buildup along the air path. Clean thoroughly with a brush and cloth.
• Step 3 – Check suction strength: Test suction at the handheld unit without the nozzle. If suction is weak there, address blockages or filter issues first.
• Step 4 – Use correct mode: Ensure you are using the appropriate power mode (e.g., turbo) for thick carpets, as low power may not be sufficient.
• Step 5 – Replace worn parts: If performance remains poor with good suction, replace the motorized floor nozzle or brush roll with a genuine Severin part.
