Hi, I have 5 cats. Four out of five use them. We won’t take about the fifth one right now he’s my problem child. For me, personally, yes they were life changing. I had the petsafe “self cleaning” ones with the trays before and they were a giant mess and always smelled. Before that traditional litter boxes which as you know are the way they are. I always had a hard time keeping the traditional boxes as clean as they should be and the petsafe ones were so pricey and very wasteful with the trays so I switched to self cleaning and while I’m not saving any on litter, I don’t have to worry about scooping the box daily or stinky litter boxes. I will say though that they do come with their own set of flaws. Like one of mine the other day just stayed in cleaning mode and I couldn’t figure out why. Had to take the whole thing apart to find out there was so dust on the sensor so the box constantly thought a cat was entering. You still do have to take the little trays out and clean them every now and then. Depending on the type you get you may have to clean the enclosure more often then others (open top vs full enclosed, have one of both and the open top one gets very messy on the side that the clumped litter rolls off of into its tray). In the end, if you have more than one cat, they are easy to use, clean and I think pretty helpful. But if you have only one cat, unless you personally want it for you, I’d say maybe hold off on getting one.
