If the dustbin always falls off during cleaning or climbing, the main reason is because the dustbin is not installed properly.

Troubleshooting steps:

• Inspect the dustbin. Please remove the dustbin from the robot vacuum cleaner and check for any visible signs of damage or cracks on the dustbin that may prevent it from locking into place securely. Additionally, please check the installation location of the dustbin for any debris, dust, or obstructions that may prevent the dustbin from inserting into the robot vacuum cleaner.
• Check the locking mechanism. Please inspect the locking mechanism on both the dustbin and the robot vacuum cleaner to make sure the locking mechanism is not damaged or broken.
• Remove and reinsert the dustbin. Simply align both sides of the dustbin with the attachment area on the robot vacuum cleaner, and then gently insert the dustbin into place until you hear a clicking sound.
