Carpet cleaner leaves streaks or lines of dirt on carpet after passes

Safety: Unplug before working on the floor head.

• Clean brush roll: Remove the brush bar and cut away hair and fibres. Ensure bristles are free and springy.
• Check bristle wear: If bristles are worn down or deformed, replace the brush roll.
• Adjust brush height: If your model has a pile height adjustment, set it to match your carpet type so the brush contacts evenly.
• Clean spray jets: Ensure the spray nozzles are not partially blocked, which can cause uneven wetting and streaks.
