Vacuum leaves lines of debris on carpet; does not pick up well at the edges of the brush.

Safety first: Remove the battery and detach the floor head.

• Clean brush roll: Remove the roller and clear all hair and fibers.
• Inspect bristles: If bristles are worn down, bent, or missing, replace the brush roll.
• Check suction channel: Look inside the head for blockages near the front edge or sides.
• Use correct mode: Ensure you are using the appropriate power mode and brush head for the floor type (hard floor vs carpet).
