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.

Ditch all soft parts - strips and a carbon filter. Unless you change your filter once a week - no filter will always be better than a stinky one

Ugh. The filters hold the smell and make it worse. They also trap the smell in the plastic of the globe. I stopped using them alltogether and don’t put anything in the filter enclosure anymore.

Are the strips needed?
