Robot vacuum leaves dirty patches and seems to miss large areas of the room

Safety first: Turn the robot OFF while cleaning sensors.

• 1. Clean all sensors: Wipe cliff sensors, front bumper IR sensors, wall‑following sensors, and any top camera or laser window with a soft, dry cloth.
• 2. Reposition dock: Place the dock in an open area with clear space around it to improve starting navigation.
• 3. Remove clutter: Pick up cables, small rugs, and obstacles that may confuse the robot.
• 4. Firmware update: Use the Rowenta app to check for and install navigation‑related firmware updates.
• 5. Map reset: Delete old maps in the app and let the robot create a new map of your home.
