Dust bin door will not latch closed or pops open during use

Safety first: Remove the battery before handling the dust bin.

• Inspect latch: Open and close the dust bin door while watching the latch hook. Check for cracks or missing pieces.
• Clean mechanism: Remove any dust or debris from the latch area that may prevent full engagement.
• Check alignment: Ensure the bin is seated correctly on the main body. Misalignment can prevent the latch from catching.
• Replace bin or latch: If the latch hook or spring is broken, replace the dust bin assembly or latch kit as supplied by Xiaomi.
