After opening bObsweep, you will see the main board in the center. To remove it, you will need to unplug 11 more circuit plugs and uninstall 3 screws.

There is one in the centre of the motherboard, near the multicoloured plug for Bob’s left wheel.

The second is close to the top right corner.

The third is near the bottom right edge.

Keep all three screws. They will be needed later while installing the replacement main board.
