How do I reset the Wi-Fi connection on the P20?

Press and hold both the Clean button and the Home button on the robot for 3 seconds, or press and hold the Reset Wi-Fi button on the remote control for 3 seconds until you hear the voice prompt. The Clean button will flash rapidly in orange, indicating the Wi-Fi has been successfully reset. Then return to the main interface in the app and click 'Add' to reconnect the robot. (Page 10)
