Vacuum leaves lines of debris behind and does not pick up well from carpets.

Safety first: Remove the battery before cleaning the floor head.

Steps to try:

• Clean floor head: Remove the brush bar and clear any debris from the suction channel and side airways.
• Inspect bristles: If the bristles are worn down or uneven, replace the brush bar.
• Check tube: Detach the extension tube and look through it for obstructions. Clear any blockages.
• Use correct mode: Ensure the vacuum is set to the appropriate power mode for carpets and that any hard‑floor slider is not restricting pickup.
