Robot vacuum displays E18 or announces a dust bin full or airflow error even when the bin is empty and filter is clean.

Safety first: Turn OFF the robot and remove the dust bin before cleaning sensors.

• 1. Clean bin and filter: Empty the dust bin completely and clean the filter as recommended. Ensure no debris is stuck in the bin's internal channels.
• 2. Locate bin sensor: Some iHome models use an optical or mechanical sensor inside the bin or bin compartment. Use compressed air to blow out dust from any small openings or levers.
• 3. Inspect airflow path: Check for narrow tubes or channels between the bin and fan housing. Clear any clogs with a flexible brush.
• 4. Test operation: Reinstall the bin and start a cleaning cycle. If the error appears immediately, proceed to internal checks.
• 5. Internal inspection (advanced): Open the robot and locate the dust bin full sensor or airflow sensor on the bin housing or fan inlet. Verify that its harness is connected securely.
• 6. Replace sensor or bin: Replace the faulty dust bin full sensor or the entire dust bin assembly if the sensor is integrated.
