Robot vacuum displays E16 and stops; often associated with stuck or misdetected top cover or sensor cover (on some Yeedi models with removable covers).

Safety first: Turn the robot OFF before adjusting covers.

• 1. Open and close cover: Lift the top cover fully, then close it firmly until it clicks. Ensure no cables or objects are trapped.
• 2. Inspect hinges and latch: Check for dirt or debris in the hinge area and latch mechanism. Clean with a dry brush.
• 3. Check for warping: If the cover appears warped or does not sit flush, it may not engage the detection switch properly and may need replacement.
• 4. Internal switch check (advanced): Open the robot and locate the cover detection switch. Verify that the actuator moves when the cover is opened/closed and that the switch cable is secure.
• 5. Replace switch or cover: If the switch does not change state when pressed manually, replace the switch or the entire cover assembly.

Warning: Do not slam the cover shut; repeated impact can break the latch or switch.
