LitterMaid® Self-Cleaning Litter Box

It's the best pet product I've ever had! I have two cats that are 11 years old and I've tried many different cat litter boxes, including semi-automatic ones. I had to clean all types of them daily, otherwise they were smelling and my cats didn’t want to use them. But this product saved my days: I didn’t clean the litter for a week, it was still clean and wasn’t smelling.(Update, 8 months after the original comment: It still works perfectly with non-clumping silica cat litter for a week without cleaning!)The negative experiences I read in Amazon were about the noise, disposable receptacles, and stuck litter on the rakes. Here are my experiences with those matters:The noise is not more than a hairdryer, so it does not disturb me much.The disposable receptacles could be a problem if you always have to buy them. But it is not necessary because you can reuse them by using bin bags in them. I can recommend you to put double receptacles and lids to make it more stable.The most common problem was stuck litter in the rakes and at the bottom of the box, also the motor struggling to move forward through the clumped litter. I tried 6 different cat litters to have the best results and 2 of them didn’t have those problems at all. Those two were light-type litters, one is non-clumping silica and another is clumping plant-based litters. Any brand of non-clumping silica and/or clumping plant-based litters work very well. Here are my experiences:-Clumping bentonite litter: The litter could be stuck on the rakes and you need to clean the rakes and the bottom. But feces and urine go into the container, although it may force the motor. It is necessary to clean the bottom by emptying the box usually. But it doesn’t smell except the stuck ones on the rakes. As a result: not very practical.-Non-clumping bentonite litter: It is stuck a little bit on the rakes, but a lot of on the bottom. Because urine doesn’t go in the container and it does not absorb the smell much, it smells a lot. As a result: not recommended.-Clumping plant-based litter: It doesn’t stick in the rakes or on the bottom, neither forces motor while working because of lightness. It works perfectly on the box. However, the light pieces of the litter were carried on the paws of my cats to the other rooms, so I had to give up using it. As a result: recommended.-Non-clumping plant-based litter: Similar to the non-clumping litter. Because urine doesn’t go in the container and it has a low absorbing capacity, it smells. Also, it is stuck a little bit on the rakes. As a result: not recommended.-Clumping silica litter: Although it's supposed to clump and take the urine in the container, it doesn't clump. The fine silica pieces get stuck on the bottom because of the urine, and get harder and higher in time so force the rakes. It is quite hard to clean the bottom from the stuck litter. As a result: not recommended.-Non-clumping silica litter: Although it doesn’t clump and urine isn’t taken in the container, it works perfectly! The litter doesn’t smell up to a week for two cats. Because the litter pieces are light, it doesn’t force the motor, so motor work perfect for feces. After a week, I emptied the container bag and the whole litter. There was no suck in the rake or on the bottom. As a result: highly recommended!I can recommend to empty and clean the whole box and the rakes weekly for the best performance of the product.(I had a single cat version for my two cats (because of the limited space) and it works for two cats very well. The first product I had was not working properly, the motor stops working in the middle of cleaning. But when I sent the video of it to the customer service, I was immediately sent a new product and the new one works very well. This is as important as the product’s function for me. Without very good customer service of Amazon and LitterMaid, I wouldn’t buy a new one and I wouldn’t use it.)
