Robot vacuum reports E11 and stops, often when the dust bin is removed or not seated properly.

Safety: Turn off the robot before inspecting the bin area.

• Remove and reseat bin: Pull out the dust bin completely, then slide it back in firmly until it clicks.
• Inspect bin tabs: Check for broken plastic tabs or magnets on the dust bin that interact with the presence sensor.
• Clean sensor area: Use a dry cloth or compressed air to clean the bin cavity, especially around any small switches or sensor windows.
• Test operation: Power on the robot and see if the E11 error clears when the bin is properly installed.
• If E11 remains: The bin presence switch or Hall sensor on the main body may be defective or disconnected, requiring internal access and replacement.
