I’ve personally had better luck with the Litter Robot 4. We started with the 3 and had some issues with the bonnet getting “unseated”, among other things. The 4 has been more stable over the year we’ve had it. The base being narrower but taller lets us get away with an extra day of not emptying.
If it’s any consolation, this is the first issue of its kind in the multiple years we’ve been using CS. Still unacceptable, but historically the program has been stable and effective for us. Hopefully this reminds higher ups the importance of proper testing before releases
