What if my Chuango Robot Vacuum RV-500 beeps 3 times with a red flashing indicator?

Anti-drop sensor error.

1. Check if the device is stuck on the ledge of a staircase and cannot reverse. Please move it to another place.

2. Please check if any debris is on the anti-drop sensors. Please clean the anti-drop sensors after the main power switch is turned off.
