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

Safety first: Turn OFF and remove the battery before inspecting the floor head.

Step-by-step checks:

• 1. Inspect bristles: Check if the brush bristles are worn down, uneven, or matted with hair. Worn bristles cannot agitate carpet effectively.
• 2. Clean suction channel: Remove the brush roll and clear any debris from the suction opening and internal channels.
• 3. Adjust cleaning mode: Use the appropriate power mode for carpets (often higher power). Some Amazon Basics models have a carpet/hard floor selector; ensure it is set correctly.
• 4. Replace brush roll if worn: If bristles are significantly worn, install a new compatible brush roll.

When to stop: If pickup remains poor with a new brush roll and clean head, overall suction or airflow may be low and should be diagnosed separately.
