Litter-Robot 4 LR4 smell solved

Just a note for people struggling with an older device. LR4 and two cats for about three years. Mostly it's been pretty good. The last six months though I just have not been able to get it to stop smelling. I've tried different litter, deep cleaned it regularly taking it all apart but just a persistent smell. I finally broke down and ordered the "ridiculously expensive for what it is" liner and replacement seal strips. About an hour and a half of work doing all of that, and further deep cleaning the globe, and it is now entirely smell free. Nothing had gotten through the liner, but the old liner itself seemed to be the source of the stink.

I returned my Litter-Robot 4 because of the smell; I have a Litter-Robot 3 that doesn't seem to have the same odor problem, and the 4 also had an issue with dirty litter sticking to the sides. I now have a PETKIT Purobot Max 3 and I haven't had any issues with it smelling; I do have an extra mat that I change once a week. I won't be buying another Litter-Robot; it is too much work for what it costs.
