Cliff sensors work on table but not on carpet stairs

February 19th, 2019, 12:04 am

Hi Guys
I have a 780. If i put the roomba on a table it works perfectly, never falling off. BITs pass as well. However i have a white carpet section which has the same carpet for stairs and the roomba drives straight off from the white carpet and down the stairs! My 630 handles it ok. I see that factory test 33 is cliff calibration...is this something i can do to improve the situation? Thanks

Have you tried running the cliff sensor BiTs with the 780 on the stairs and observe when the cliff sensor triggers?
