Clean Base (self-emptying dock) reports an error and the robot cannot empty its bin; app may show “Clean Base Error 1: Check the bag”.

Safety first: Unplug the Clean Base before opening it. Dust may be present; consider wearing a mask if sensitive.

Steps to resolve:

• Open Clean Base: Lift the lid to access the bag compartment.
• Check and replace bag: If the bag is full or very heavy, remove and dispose of it. Install a new iRobot-compatible bag, ensuring the cardboard collar is fully seated on the inlet tube.
• Inspect inlet for clogs: Look into the inlet where the bag attaches and remove any visible debris.
• Close lid securely: Ensure the lid latches fully; some models use a lid switch for safety.

When to replace parts: If the error persists with a new bag and clear inlet, the bag detection switch or Clean Base electronics may be faulty and require service.
