I am working on a Roomba 780
with the Dock and Clock lights missing (I think). This the first time working on a 700 series Roomba. From a few youtube videos, I saw the lights for the Dock and Clock buttons. The Dock and Clock lights are not on.
The BiT indicates that the right rear cliff sensor had failed. The failed cliff sensor stops this 780 from starting a mission. I took the top cover plate off. After removing 12 screws under the top plate, I cannot take the main cover off. Something is still holding it to the bottom assembly. Have anyone ventured to remove the main cover! Any help will be appreciated.
Found 2 more screws under the silver half circle piece located near the control button. But something is still holding the main cover...
