This worked :To turn Child & Pet Lock off without the app, tilt the robot so that one wheel is pressed into the ground (the wheel springs are fully compressed) and the other is floating in the air (the wheel springs are extended, not compressed). While holding the robot in this tilted position, press the CLEAN button 3 times. You will hear a sound and the light ring will illuminate white for 3 seconds to confirm. You will be able to hear a chime sound once you have disabled Child & Pet Lock with the appropriate button combination.
