MeoWant Self-Cleaning Cat Litter Box - 75L Extra Large Automatic Litter Box for Multiple Cats with Safety Protection, APP Control & Odor Elimination | Smart Litter Box with Mat & Liner for Home Use | Perfect for Busy Pet Owners & Multi-Cat Households

I have had a Litter Robot 3 for just over four years, and it has been relatively problem free (occasionally has faults, mostly due to me putting too much litter in). However, it is very tall and I have a kitty with bad hips and noticed him having difficulties getting in/out of the Litter Robot, even with the steps. So, when I saw an ad for the Meowant SC02, I was interested in giving it a try because it has a much lower entry. I finally got one and set it up, and my kitty immediately started using it. He can get in/out MUCH easier, to my relief. Some things I have noticed that I like better about the SC02 compared to the LR3: it is a bit smaller dimensionally; being a tiny bit narrower and much shorter so it may be a better choice if you need it to fit into a smaller space. It is FAR quieter; I can hear my LR3 cycling across the house but barely hear the SC02 cycling when I'm the same room. It also seems more sensitive to a cat's weight that the LR3, which sometimes did not register my kitty who is about 6.5 lbs and on occasion would start to cycle with him in it. The SC02 has no trouble sensing his weight so the risk of it cycling while occupied is significantly reduced. I like that the cycle time isn't limited to specific intervals, and there is more flexibility in programming. I also prefer changing the bin on the SC02 as I don't have to move the steps and pull a tray out from under it. The deodorizer seems to work better as well. I haven't been able to get it to calibrate properly, but it may because we have bare floors during a post flood remodel. Hopefully it will calibrate later on when the new floors are in. It is a bit odd that it doesn't have a power button and can only be power cycled by physically unplugging it. I have heard that the Litter Robot 4 offers the same features that the Meowant has over the LR3, but at more than twice the cost. This is a fairly reasonable price automatic litter box, and it is a safe design that doesn't have a closing mechanism that could trap or crush a cat. It also needs less litter than the LR3. I would highly suggest searching for the separate sifter with smaller holes as the one that comes with it has larger holes that allow waste bits to sneak past. All in all, highly recommend! I hope it lasts a while.Update: I added the above mentioned replacement sifter with the smaller holes as it seems more effective for small particle litter (I recommend leaving the original sifter in for larger format litter like pine), and also a snap on barrier on the bottom of the entrance because someone (and unknown one of my three kitties) peed out the opening more than once. These have definitely helped but the BIGGEST code cracked is how to keep it as clean as possible. Clumps were sticking to the inside of the barrel - just like they would do in my LR - and it was frustrating. So, I cleaned the surfaces really well, wiped down the interior with Armor All and then wiped off the excess, and switched to Arm & Hammer Hardball litter. Not only does the Hardball litter clump tightly, so far none has stuck to the inside of the barrel AND it's a super soft litter which will be more comfortable for little peets.
