Robot vacuum displays E7 and may not detect the dustbin correctly.

Safety first: Turn off the robot before removing the dustbin.

• Remove and reinstall bin: Take out the dustbin, check for debris around the latch and sensor area, then reinstall until it clicks firmly.
• Inspect latch and tabs: Ensure the plastic tabs on the bin are intact and not bent.
• Clean sensor area: Use a dry cloth or compressed air to clean the bin cavity and any visible switches.
• If E7 persists: The bin detection switch or sensor may be faulty and require replacement.
