Robot vacuum frequently reports that the bin is full even when it is empty (no specific code, just voice/app message).

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

Steps to resolve:

• Clean bin and sensor windows: Empty the bin and wipe all internal surfaces. Pay special attention to any small clear windows or sensor housings.
• Clean robot-side sensor: Look into the bin cavity on the robot for the matching sensor window and wipe it gently.
• Reinstall bin firmly: Ensure the bin is fully seated and latched.

When to replace parts: If false full messages continue, replace the bin assembly. If that does not help, the internal bin full sensor board may need replacement.
