Remove Roomba's Dust Bin.

Remove Roomba's old faceplate by pulling the faceplate up from the side, all along the front to the opposite side, until only the back tabs are holding it in place.

Push the faceplate back to release it off Roomba.

Install Roomba's new faceplate by inserting the faceplate's back tabs into the appropriate Roomba slots.

Tuck the front edge of the faceplate under the Virtual Wall sensor (the 'eye' along the bumper).

Push firmly on the inside and outside edges of Roomba's faceplate to secure it in place.
