Exact same instructions for a Roomba 690. Great guide and much cheaper than sending it in for out of warranty repair at $135 bucks!!!

Outstanding! I would only add to note position of the 12 top plate screws as they are removed since 3 are smaller/shorter (although not noticeably so) and need to be returned to their exact location. I would not call this difficult. Simply tedious. Thank you very much for the instrucitons.

Thanks for this. Roomba wanted me to send my unit in for repairs costing $130. I bought a replacement Rcon at eBay for $10. Turned out, as others have posted, the red wire was broken! That’s on Roomba!! Works like new, will repair the red wire, and save the rcon for future use.
