Robot vacuum randomly stops and reports completion even though the area is not fully cleaned (no error code).

Safety first: Ensure the robot is fully charged before starting a large cleaning job.

• Battery check: If the robot often stops early and returns to dock, the battery may be weak and need replacement.
• Sensor cleaning: Clean cliff sensors, floor tracking sensors, and any navigation cameras or turrets.
• Firmware update: Use the app to check for and install the latest firmware, which may improve navigation.
