After weeks of research, months of long-term testing, and many long hours spent scrubbing out and troubleshooting boxes that didn’t make the cut, I’ve narrowed the list down to six units with the potential to save you time and make your cat happy.
While no one automatic litter box is perfect for everyone, the following products met the Cats.com standards for build quality, performance, and overall customer experience. Read on for the details.

Why Should You Trust Us?
Over the past four years, I’ve personally tested more than a dozen automatic litter boxes with my two cats, Wessie and Forest. Before putting them to the test, I spent hours researching the products to learn how they were designed and manufactured. I also scoured the Internet for customer reviews to identify frequent customer complaints and to get a feel for the general customer experience with each company.

When testing self-cleaning litter boxes, I take notes on everything from how long it took to set up the unit to how often I needed to empty the waste receptacle. I made observations about litter scatter, odor control, and overall performance. My cats, of course, provided their opinions—in some cases by refusing to use certain models at all.
Based on this extensive research and hands-on testing, I’ve selected the following automatic cat litter boxes as the best you can buy.

What Should You Look For in an Automatic Litter Box?
cleaning model may be the right choice. But while there’s no shortage of options on the market, some of them simply aren’t up to snuff.
Before you invest several hundred dollars in a high-tech litter box solution, make sure it’s going to deliver on its promises. Here’s what to look for when shopping for an automatic litter box.
An Effective Design
While all automatic litter boxes promise to save time and make your life easier, our tests have found that most of them have design flaws that could make them more time-consuming than a regular box. That’s why it’s important to choose a self-cleaning box with a smart, effective design.
Look for ones that don’t have many open gaps and cracks that can collect waste or allow urine to leak down below the drum or litter pan. If you’re looking for one with a raking mechanism, make sure that the rake is able to reach the bottom of the pan and is strong enough to capture heavier clumps.
The litter box should also work quickly and quietly, ensuring that neither you nor your cat is disturbed when it runs a cycle.
Ease of Cleaning
While you won’t need to scoop an automatic litter box, you will need to clean it out periodically. It should be easy to pour out the litter and spray or wipe out the inside. That’s why we recommend choosing one with an automatic emptying feature and minimal crannies where waste can get stuck.
Cat Activity Tracking
Your cat’s litter box is one of your most valuable windows into their health, which makes scooping time a great opportunity to learn how your cat’s doing. A good self-cleaning litter box incorporates cat activity monitoring features. An app with an activity log, especially one that specifies your cat’s weight as well as how many times they’ve used the box, will help you to keep track of changes in your cat’s habits and flag potential issues sooner.
Fits Your Budget
One of the top questions people ask about automatic litter boxes is “Are they worth it?”.
The answer to that question involves a cost-benefit analysis that only you can perform. It’s a good idea to recognize that the most expensive boxes aren’t always the best. Realize, also, that the long-term cost of the litter box is more than the number in the Chewy checkout.
Like a cheap printer that costs you hundreds of dollars a year in ink, some automatic litter boxes, like the CatGenie, require special supplies that may end up costing a lot more than a regular box full of cheap litter.
On the other hand, some expensive units can save you money over time. The Litter-Robot, for example, is known to keep cat litter cleaner for longer, and it’s compatible with virtually any clumping cat litter. While the upfront cost is high, it may end up helping you save money over time.
Made and Sold by a Reputable Company
With units starting at $150 and going up to $700 or more, a self-cleaning litter box is a major investment. The best ones come from companies that stand behind their products, offering at least a 1-year warranty and responsive customer service.
How to Help Your Cat Start Using a New Automatic Litter Box
Between operating noises and unexpected movements, a self-cleaning litter box may be jarring to your cat. To avoid “protest poops” outside of the box and an unhappy cat, make a gradual transition, gently acclimating your cat to their new box.
First, place the automatic litter box in a familiar, comfortable area where your cat feels safe. Start with the unit turned off to let your cat become comfortable with it. If you start with the litter box turned on, the noise and motion of a cycle could scare them off.
Instead of removing the old litter box immediately, keep it in the same room but stop cleaning it. Help your cat to recognize the new box by transferring a scoop of dirty litter. In time, your cat should choose the cleaner box. Once your cat is using their new automatic litter box, turn it on and let them see it cycling between uses. After a few weeks, your cat should be comfortable with the new box.
Remember that some cats will never love their automatic litter box. In our tests, some cats liked the automatic boxes, and others didn’t. One of our cats consistently used a traditional litter box when given the choice. Forcing your cat to do something they don’t want to do is never a good idea, so we recommend always providing an alternative litter box.
Frequently Asked Questions
Do automatic cat litter boxes really work?
It depends on which one you get! A well-made automatic litter box effectively cleans after each use and allows you to skip scooping. However, a lot of automatic litter boxes are more hassle than convenience, so it’s important to pick the right one.
What is the best litter to use for a self-cleaning litter box?
While some self-cleaning litter boxes require special litter, most of them work best with high-quality, hard-clumping litter. Most don’t work well with pellet-style litter, non-clumping litter, or litter that creates soft clumps.
Do self-cleaning litter boxes smell less?
Because a good automatic litter box cleans after each use and stores the waste in a sealed compartment, it will smell less than a regular box. However, our tests have found that a poorly-designed automatic litter box can end up smelling a lot worse than a regular box. Bad automatic litter boxes tend to have nooks and crannies where waste can get stuck, meaning that it’s harder to get them thoroughly clean.
Can you use regular litter in a self-cleaning litter box?
It depends on the self-cleaning litter box. Most are compatible with any type of clumping cat litter, while others only work with crystals. Some automatic litter boxes require proprietary litter only available from the manufacturer.
Do cats prefer clean litter boxes?
Absolutely! Cats have an extremely sensitive sense of smell and love being clean, so it’s only natural that they prefer clean litter boxes. Compared to inconsistent manual scooping, an automatic litter box can help to create a fresher, more comfortable bathroom for your cat.
Are cats scared of automatic litter boxes?
Some cats are startled by the noise and movement of an automatic litter box. That’s why it’s a good idea to acclimate a cat to their new box before turning it on.
I bought the I litter robot and thought that it would be more clean but found it to be more disgusting because of the fact that it rotates to dump all that dirtiness and dust from the litter (the urine-soaked litter) go up the wall over the ceiling and dump and then it rotates back down so you still have all that nastiness along the insides of the wall. And if you don’t clean it every time it Cycles that’s just nasty!
Litter robot is great for my females but NOT for my male who even though he is neutered tends to spray up and back when he urinates. This means the back is wet when it rotates and the litter clumps on it and gets stuck on the grates. Worse, some of that urine goes out the opening and runs down the sides and collects in the bottom. I didn’t realize this until the stench was overwhelming and I took it apart to figure it out. My solution has been one regular box and one litter robot. The male never liked the litter robot anyway so he uses the regular box. So… I still have to scoop but not as often.
Hi
I had same problem the litter robot would stop midway at times
I came home from a 2 day trip to find the worst mess ever
Also tried Chilx so cheaply maid first 24 hours the item had urine dripping from sides
Plastic cheaply made
I had safe LitterMaid with crystal cartridge for years but had to replace every 5 days the smell from the crystals was awful
I guess I’ll try the LitterMaid for clumping litter
Hi, thank you for sharing your experience!
looking at the Chillx litter box This looks like a China made product that you can buy on Alibaba for $180 When you buy more they will put your logo on them and get a it a little cheaper
was looking at the eversweet review and found a new self clean litter box from petkit.
any chance we can take a look at this product as well? 🙂 thanks in advance!
(p.s. own 2 litter robot 3 and both of them are not working as expected, not always detecting my cats and sometime just freeze in middle… had the wifi board installed and was never able to connect so the app is non-exist for me…)

Hi Zhen, we plan to review the Petkit Pura X very soon. Thank you!
What about the Els Pet self cleaning litter box?
Hi Micca, Mallory is no longer available to respond to comments but I looked into the Els Pet litter box a little bit. It looks like a promising option, definitely a different design than many models on the market. My main concerns are the size (the opening is a little small) and the raking technology may leave behind pieces of dirty litter (as with the PetSafe ScoopFree).
I’ll mention it to the editorial team to see if we can review it. In the meantime, let us know if you try it out!
Hi i hve a PetKit litterbox and both our 11 cats and i love it, best thing ever and i also bouth one called MEET Cat toilet witch is also brilliant nut the PetKit one also weighs the cats accuratly ,,you do have to wipe down the insdide once a week but so much better than scooping out the trays ..also no smell as it deodorises so a win win
Hey have you check out this new one on Kickstarter
https://www.kickstarter.com/projects/catsonlitterbox/an-affordable-auto-litter-box-that-cares-about-you-and-your?ref=discovery&term=automatic%20litter%20boxes
I have noticed many automatic type litter boxes lately on my facebook feed – I often wonder if they are any good. Some are a lower price point then the Litter Robot, I currently have the 3 but with 5 Ragdolls another one would be nice if it wasn’t for the price.
Hi Rebecca, we haven’t looked into the Catson litter box yet, but we can certainly consider it for a future review. There are, indeed, quite a lot of automatic litter boxes on the market, with Facebook and other social media outlets being popular advertising platforms. We’d love to review them all!
Hi i have both the PetKit and the MEET cat litter ones and love them both but PetKit also weighs the cats quite accuratly so yes try to test them both out another one that looks good are the PETREE one thinking of ordering that one, always good to try out different ones and they are around $ 500 cheaper than the Litter Robot Cheer from Australia
Hi there! Hope you’re doing well in Australia—I know things have been pretty crazy down there recently. I’m trying out the Petkit Pura X automatic litter box right now, so I hope to get back to all of you guys with more details soon.
I am really looking forward to the review of the Petkit PuraX as I am considering it against litter robot. However, from the research I have done so far I have noticed that acquiring parts for litter robot is very easy from their website and every part seems to be replaceable whereas Petkit on the other hand have no parts for sale on their website.
Yes, that’s true. The other issue with Petkit is that their app is not well-adapted to English and customer support is not as accessible compared to that of the Litter-Robot. Will come back with more details soon!
Nothing personal, just a pet peeve. As a former copy editor, I wish reviewers the world over would stop writing “price point” when they simply mean “price,”
The phrase has become jargon. One could just note that something is cheaper or costlier.
(I may just need some sleep.)
I’ve had the litter robot for years now. It’s been predictable and does a great job at cleaning. Sometimes it will get stuck, but that’s easy to fix. Not to mention the support is very good. Both of my British shorthair doesn’t have any issues using it.
We’ve had the PetSafe Scoop Free Litter Box for almost 3 years now, and it stopped working completely. My spouse (who knows mechanical engineering) took it apart and found that the rotating gear mechanism for the rake is made of PLASTIC parts, when those parts should be metal. The result is that the gears wear away with time and usage, and the teeth that are supposed to grip are stripped completely. They’re basically smooth now, and the rake won’t move anymore.
So while this litter box was wonderful while it worked, it is guaranteed to FAIL irreparably in 2-3 years. The inside is designed to NOT last.
I contacted the company about this and they offered me a 10% off coupon to buy a new one. Sounds like this is their business model.
Phrannie, thank you for sharing. Great observation on the gear mechanism being made of plastic parts that are prone to stripping—I think this observation will help a lot of people to make a more informed decision on whether or not they buy this box.
I hated the PetSafe Scoop Free litter box. It was fine when we had just one cat but when we had more than one, it felt like we were replacing the tray every week and it was so pricey. Plus the crystal litter was such a hassle and I felt that because it never clumped urine, the smell was just overbearing, even with stirring it up after any time they peed. It became more of a hassle than a regular box.
its too expensive Unfortunately we cant buy it in iran.. if i would there
Wondering if you have considered doing a review of the Omega Paw ‘Automatic’ litter box (large) – I know the (affiliated?) site “All About Pets” did a review on it, but it was several years ago.
Plus, I really value the insight of you and your team here at All About Cats; it would be great to get your take on the Omega Paw as it seems to be a promising middle ground that could speed up the litter cleaning process without the expense of a litterRobot, etc. it would be great to get your take on how it stacks up with the other boxes you’ve tested!
Thanks for the great site & content!
Hi Nick, that’s a great question! We did review the Omega Paw Roll ‘n Clean some time ago, but that review is absolutely in need of an update. We’d also be interested in doing a video review of this product. I’ll add it to the list!
I am curious about how these compare to the Smarty Pear Leo’s Loo Too Cat Litter Box. From reviews on Chewy, it seems to be very good and some people like it better than the Litter Robot 3. I guess the other question will be how both compare to the Litter Robot 4 now that that’s out.
Jenna, the Litter-Robot 4 is worlds ahead of the Leo’s Loo Too. I’ve found the unit to sift ineffectively, and the handle placement made it nearly impossible to carry it around. I don’t consider it to be at all worth the cost. We’ll do an in-depth review of it soon.
I have a Leo’s Loo and love it. I have never had any problems with it sifting, and I’m not sure why you would need a handle to carry it around? I have 2 cats and they also love it. It is less fancy than the ones that have apps and all that jazz, but it’s simplicity also means it comes at a cheaper price and I don’t worry about it breaking. It also has a very large interior, which I also find useful.
Thanks for sharing your experience.
Hi. Any chance you will be doing a review of the Instachew Purrclean self-cleaning litter box? I’ve noticed that some reviewers much prefer it to the Litter Robot, so I would love to see a review of it by you. Thank you!
Looks interesting! I’ve added it to our list of products to consider for review. Thanks for sharing.
I was interested in the Instachew Purrclean too, but it looks just like a couple other units: “Self-Cleaning Cat Litter Box, Catboat” on Amazon and “Pet Marvel smart intelligent cat litter box toilet APP remote control self cleaning litter box machine with digital display” or “Large Automatic Cat Litter Box Self Cleaning Big Cat Litter Box APP Control Safe Cat Toliet Machine” on Alibaba. So not sure it’s manufactured by a reliable company.
Good observations—I’ve noticed that as well, and unfortunately, I can’t say for certain whether or not it is a white-labeled product from Alibaba. However, I’ve been testing it out myself, and I’ve had some issues with litter and urine making their way underneath the rotating drum, and the overall performance is not very impressive. I should be able to come back with more details soon.

I have been using the Pet Kit Pura Max for about 2 months and think it is great! I would be interested in seeing what you think about it and how it compares to the Pura X. Thank you for your extensive research done on this it is super helpful!
Hey Emma, we did recently review the Petkit Pura Max here!
Mallory, Is there a chance you will be reviewing Smarty Pear’s Leo’s Loo Too in the future? We are contemplating this investment late this year, so I’d love to see your opinion, especially compared to the Litter Robot 4. 🙂 Thanks!
Hello Wendy, at this time, we don’t plan to review the Leo’s Loo Too. Thank you for asking!
Interesting comments. We bought the Elspet / Hillpig. We’ve had it for about two months and are quite satisfied with its performance, safety features, cleanliness and reliability. Got quite a good price on Amazon. I’m considering buying a Litter Robot 4 (We Havertown cats!) because of all the great reviews by “professional reviewers” but users seem to be less enthusiastic about it.
As they disclosed, reviewers take a cut. I’ve seen it elsewhere, maybe youtube. Like 15%? 20%? The litter robot is so pricey and buggy. Outdated product really.
Nice read. But I’m surprised the Popur X5 was not covered. Extensive research – you bet. I started as a Kickstarter backer and now I have four of them that replaced my old litter robots and petkits. Haha
Hm, you’re right that this is one of the automatic litter boxes that was not tested for this review, but I can assure you that we did the research and testing described in the content of this article. As for the Popur, this review from One Man Five Cats concerned me—seems that the Popur X5 has some safety issues that the company is not acknowledging or correcting, and the functionality is imperfect as well. It didn’t make it into our testing, but I felt comfortable not recommending it based on what I’d seen about it online.
I’m glad I have my own experience instead of being misled by the so called influencer and the hearsay. I saw that video when someone mentioned it on kickstarter. I’ve to say anyone can make a scene easily by pausing the machine and putting a doll behind the rake purposely. I see it impossible in real life because the gap is so small when I use a normal amount of cat litter. On kickstarter I saw only one complaint about safety in the early days but she clarified that her front guard was missing. That’s the reason. Also I can’t recall when but it was long ago that they changed the software and the rake retracted first before the box returns.
As disclosed that guy earns commissions from what he recommend, I think his integrity is questionable. After watching the video I chatted with their support and raised my concerns. They said that their boss had a fight with that person and it became real personal. The guy had a pre production prototype that was different from what we backers received. I was told the guy threatened popur company in the first place and even used the F words many times in emails, and they tried to post response on youtube but the comment got removed. Also they told me they had no more intention to respond to that guy directly as they are busy serving the customers and making better products. But in reality they discussed everything during kickstarter updates including the safety issues. I can testify that they are devoted to improving the product and attending their customers. That’s my experience at least. Anyways, their fight is none of my business all I wish is the company will outlast my litter box haha but they seem to be doing pretty well with all the great reviews on amazon. And yay I just bought my second popur on prime day today. But sadly no discount at all…
Hmm, I see. I will have to test it out as well; you’ve raised some interesting points.
I’ve switched from Litter Robot 3 (which was a disaster with a tall cat) to Popur and very happy so far.
Any chance you will review the Smarty Pear Leo’s Loo Too?
Hi Richard, I did test out the Leo’s Loo Too but have decided against including it in this review—my experience with it involved poor design and functionality, so I don’t feel comfortable recommending it.
Thank you.
Hi, do you have an automatic litter box review dedicated to performance using alternate litters? I’ve been considering the PetKit PuraMax, Pura X, or the PetSnowy SNOW+ but I’m concerned about how well they’ll work with wood litter. I use ökocat original and super soft clumping wood litters and while many of the automatic boxes say they work well with *most* clumping litters, I haven’t seen any that actually mention being wood compatible.
Hey Monica, that’s a good request, and unfortunately, we have not yet done comprehensive testing with multiple litter types. I do know that Okocat’s wood clumping litter tends to be a little bit softer-clumping, which will be a problem with these automatic litter boxes. Also, these types of litter tend to hold more humidity, which I know can be a problem for the Litter-Robot’s sensors.
Hi All and Mallory,
Does anyone have a link to Litter-Robot where I could potentially save some $$ and you could get some store credit as well? My email address is [email protected].
Thank you for your time and consideration.
Roddy
Hi! Have you done a review on the Pet Snowy Snow+ automatic litter box? I am considering between that one and Litter Robot 4, and would love to know your thoughts. Thank you!
Hi Isabela, I’m working on it now! Thanks for the request.
Hey, we at Instachew would really appreciate it if you could review Purrclean – our automatic litter box. We have been in the business for quite a while and have received good response to our litter box. Visit – https://www.instachew.com/purrclean-smart-litter-box
We’ll add that to our list!
I purchased the Cat Genie 1 1/2 months ago. Very happy with it. We have 4 cats, I’ve got it set to a 4 hr time activation. I wish it had a larger diameter bowl and taller dome. There is little to zero odor between cleaning’s. This has been a huge time saver for us. With a regular cat box ($45 month), cleaning 2X-3X daily, it was difficult to keep up with the smell, disposal & maintenance. Our cats have gotten use to it & if it is in the middle of the cleaning cycle, they appear to line up for it to finish. They haven’t figured out that it will stop cleaning if they go in & resume cleaning after they leave. Honestly, I do think it’s a fair price for the amount of time that I’m saving & our homes comfort for all of us. The phone app is helpful, we can adjust cleanings remotely & lock them so our fur toddlers don’t reset them. Their ages ranges are: 7 – 16 years old
