5 Best Self-Cleaning Cat Litter Boxes [Tested and Reviewed]

PETKIT is a brand dedicated to creating products with both smart design and great functionality. The PuraMax also offers the option to add a specially designed deodorizer, so if you're concerned about smells, check it out.

In the disposal tests, this product processed waste every time, no matter where it was. The safety function was also excellent, keeping the box stable even if jumped on. With no dangerous parts, you can use this box with peace of mind.

The dome can be easily removed using the magnetic cover and hooks, and both the litter storage area and grate are simple to remove and therefore keep clean. Since the litter box is at the front, it is easy to open, with a full discard function that makes it very user-friendly.

As for the app, the home screen is clear and intuitive, and its features are abundant. It offers data capture for weight, number of excretions, and duration, with individual graphs for each cat that make it easy to keep track of all your pets’ health. The scale is also very accurate, never exceeding 100 grams. However, some terms used are confusing, and the sheer amount of features may be overwhelming for some.

The odor emitted was barely noticeable a week after initial use, most likely because the opening is smaller than in other products. There was a faint smell during the emptying process, but not enough to be uncomfortable. Finally, with an operating noise of just 43.7 dB, this very quiet litter box won’t disturb you, even if placed in a bedroom or study.

Whether you have one cat or several, this is the best automatic cat toilet that is easy to use and keeps clean and hygienic. 

If you’re still on the fence about an automatic litter box, consider the Snow+ Self Cleaning Litter Box from California-based PetSnowy, which offers a 30-day trial period.

During our tests, this litter box handled all solid cat litter without any problems. The safety features also worked well, and we found no potentially harmful parts. However, its taller height makes it somewhat unstable, causing concern that it could tip over if jumped on. This brought its score down in the evaluation.

The dome is easily detachable just by lifting it off, and the litter storage and grate can also be removed by hand. It's simple to manage accumulated waste thanks to the opening, plus it comes with the coveted full litter disposal function.

The app is user-friendly, with appealing colors, large icons, and all the information you need on the home screen. With a maximum error of only 100 g, even with movement, it’s safe to say that the scale accuracy is excellent. Also, since it allows you to monitor weight, frequency, and duration, managing your cat's health will be a breeze.

With a barely noticeable odor and a pre-sealed waste bag function, you can clean up quickly without unpleasant smells. The operating noise of 45.9 dB is relatively quiet, but it may bother people who are very sensitive to noise. You may want to avoid placing this one in the bedroom or office.

Overall, this is a great option to consider for those who are sensitive to odors or have a strong aversion to handling waste.

The Litter-Robot 4 by Whisker has been meticulously designed for comfortable use by cats of all sizes. Besides self-cleaning litter boxes, the brand also sells automatic feeders and cat litter, so you can grab everything you need at once.

 
This product scored well in our tests for waste removal and safety, making short work of all used cat litter and offering fully functioning safety features. The wide opening also makes it easy to clean. Again, however, while the larger size is a plus, it’s less stable and thus a worry if your cat decides to jump on it.

 
Other plus points are that its dome is easily removable by simply pressing the side button, and it also comes with a full litter disposal function.

The app has good-sized icons and text, but some elements are difficult to use intuitively, as it takes a while to locate and access the functions you need. It’s also not ideal that it can only record weight and visit frequency. On the upside, it offers the desired maximum 100 g weight error.

It contained odors well, even after a week, but when you pull out the litter disposal the accumulated waste is exposed. This caused the smell to linger when cleaning up, which is a disadvantage. Finally, while the operating noise is fairly quiet at 45.5 dB, it could still disturb some people. This litter box functions well but is best placed in rooms where noise isn’t an issue. 

MEEGEEM specializes in automatic litter boxes for cats. This model features a radar sensor that pauses operation when a cat approaches.

During our tests, it had no issues collecting waste, though we noticed litter can easily get underneath the dome. This was one of the best performers in safety tests, as it did not move an inch even with the weight of a cat jumping on it. With no worry about it tipping over and no unsafe parts, your furry friend won’t come to any harm.

 
As for maintenance, the grate and litter drawer can be removed by hand, but you’ll have to unscrew the dome for a full clean, which could soon feel like a hassle. Fortunately, the dust box is at the front for easy access and there’s a complete litter disposal function to make up for it.

 
The app is a mixed bag. While intuitive and user-friendly on first impression, it uses a strange combination of upper and lowercase letters and confusing function names like 'clean' and 'clearance'. It can also only record and display weight in kilograms and does not measure in 100 g units. For keeping track of your cat's health, this may be insufficient.

Although we couldn't detect much odor escaping from the dome, the litter box and accumulated waste were left exposed. The fact that smells easily linger during cleanup isn’t ideal. Additionally, the operational noise of 49.6 dB would be noticeable in a workspace or bedroom, so it won’t suit those placing it in these parts of the home. 

A more style-focused option, Casa Leo’s Loo Too is available in a choice of four colorways: gray, blue, pink, and this smart avocado green.

 
This litter box earned good scores for waste removal, collecting all the used cat litter. But it really impressed in the safety tests. Thanks to the wide sensor positioning, the safety functions turn on as soon as a cat approaches. The risk of tipping over is also unlikely and there were no parts that could cause injury, so you can leave your cat home alone without worry.

Once you've removed the cover, you can easily lift off the dome. However, you'll need to unscrew the grate, and you can't remove the litter section. The opening is also narrow. Although the litter tray is conveniently located up front, there's no full disposal function, so you'll have to lift the dome and dispose of the soiled litter each time. All of these points will make it more of a hassle to clean and maintain.

 
The app is simple and intuitive, but there’s very little information available. For example, it only records weight, and this data isn’t shown in a graph. Also, the measured weight can vary by up to 1.76 lbs depending on your cat’s position, so its accuracy isn’t great either.

 
While the dome contained odors both immediately and a week later, the smell tended to linger when testers opened it for waste removal. If you’re looking for something with an undetectable smell, this won’t fit the bill. Finally, the noise level of 49.6 dB might be slightly annoying in bedrooms or workspaces.
