Robot vacuum leaves streaks of dust or lines of debris on the floor after cleaning.

Safety first: Turn OFF the robot.

• Inspect main brush: Check the Hoover main brush for worn, flattened, or missing bristles. Replace if worn.
• Check side brush: Ensure the side brush is installed, not missing, and that its arms are not bent backward. Replace if deformed.
• Empty dustbin: Make sure the bin is emptied before each run to maintain airflow.
• Run on max power: If your model supports it, select a higher suction mode in the app for carpets or heavy debris.
