Robot shows E11 and stops with the dustbin installed; suction may not start.

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

Step-by-step:

• Remove and inspect dustbin: Check for cracks or broken locking tabs that might prevent full insertion.
• Clean bin cavity: Use a dry cloth or small brush to remove dust from the dustbin slot and around the detection switch.
• Locate detection switch: Look for a small plastic lever or micro‑switch inside the dustbin bay. Gently press it to ensure it moves freely.
• Reinsert dustbin: Slide the bin straight in until it clicks. Do not leave it partially out.
• Test operation: Turn the robot ON and start a cleaning cycle. Confirm that suction starts and E11 does not appear.

If E11 persists with a good dustbin: The dustbin detection switch or its wiring harness may be defective and require replacement.
