Robot vacuum shows E12 and stops with the dust bin icon lit or announced

Safety first: Turn OFF the robot before removing the dust bin.

• 1. Remove and reseat bin: Pull out the dust bin completely, then firmly push it back in until it clicks. Ensure no foreign objects are preventing full insertion.
• 2. Clean bin sensor area: Look inside the bin compartment for a small mechanical switch or optical sensor. Use a dry brush or compressed air to remove dust buildup.
• 3. Inspect bin tabs: Check the plastic tabs or magnets on the dust bin that interact with the sensor. If a tab is broken or a magnet is missing, the bin may not be detected and the bin assembly should be replaced.
• 4. Test without debris: Empty the bin, reinstall it, and start a cleaning cycle. If E12 no longer appears, the issue was likely dust accumulation.
• 5. Internal harness check (advanced): If the error persists, open the robot and verify that the bin sensor harness is connected securely to the main board.

Warning: Do not bypass the bin sensor by taping it closed; running without a bin can cause internal contamination and motor damage.
