    • Flip your Roomba over so you are looking at the face of your device.

    • Using a plastic opening tool, pry the face plate off of the Roomba.

    • While prying the the face plate off of the Roomba, do so gently. Do not force the plate off as this could result in broken pieces.

    • This next step will require some force as the cables are securely connected to the motherboard at this time.

    • Remove the two cables that connect the bumper and sensors from the motherboard.

    • As you can see in the photo, the cable and the location of where it goes on the motherboard are marked with their respective shapes.

    • Fully disengage the bumper, along with the skinny IR sensor track from the main part of the device.

    • The sensor track is hidden underneath the bumper, but it connected with several wires.

    • Rotate the device 180 degrees so you are looking at the other side.

    • Remove the cables that are holding this part of the motherboard in place.

    • This might require a bit of tugging. We recommend gently wiggling the cable at the base, to help loosen the hold.

    • Remove the 6 bumper sensors from the side of your device.

    • This will require some tugging as the sensors are securely situated in the device currently. We recommend using a spudger if they are particularly difficult.

    • You might need to cut the tape that is currently holding several sets of bumper sensor wires together. It might be helpful to tape the new sensor wires back together when putting your device back together.

    • As you can see in the third photo the cable from the bumper sensor was originally connected to the motherboard.

Great tutorial! I was lucky to only need to follow directions to the point of removing the bumper, just enough to reposition the metal tension springy thing in front. Obviously, I’m a neophyte and need easy to understand, illustrated content to accomplish anything mechanical. You provided everything necessary to get my Roomba back to work. Thank you!
