Bought two s7s for my two floor townhouse. One of the s7s work fine, the other get 4-5 "bumper stuck" errors every cleaning run.
I swapped them around and confirmed there's something wrong with that one robot that keeps getting the error.
I had a friend buy this in the U.S. and shipped it to me in Canada. I tried asking support for help, but they weren't willing to pay for the import fees of cross border shipping.
I'm currently trying to figure out what I can do by myself. Should I open up the robot and attempt to see what I can do? Do they sell spare parts somewhere? Are there any guides to self-servicing these bots?
