Thank you very much for this useful guide. I cleaned properly my cliff sensors and all the Robot with the air compressor. Now it works properly and it looks like new!

Very complete instructions! Thank you so, so much! There were a few points along the line that I thought I was going to break something but trusted your instructions and everything worked out perfectly! I actually didn't replace my Cliff sensors but took them apart as somehow they had gotten dirt inside of them. My floors are finally clean again and you saved me between 300 + $400!

Thank you. My roomba was stopping every 5 minutes or so with the “move to a new location” error message. I took it apart following this tutorial and opened the cliff sensors to clean inside of them (with a q-tip dipped in alcohol). After putting everything back together my old roomba is working perfectly again! Thanks for the detailed instructions! The color coded pictures with the screws was most helpful!
