Though no longer the latest model in Whisker’s lineup of automatic, self-cleaning litter boxes, the WiFi-enabled Litter-Robot 3 Connect offers consistent performance and strong odor control. At around $550, however, it could be the most expensive device you’ll ever buy for your cat. Is this rotating litter sifter worth the money?
After testing the Litter-Robot 3 for over a year, we’re bringing you the details on how this automatic litter box works and my personal experience using it with my two cats.

Here’s How You Get Started With The Litter-Robot
Why Trust Cats.com
Over the past several years, the Cats.com team has spent hundreds of hours researching and testing automatic litter boxes. I’ve tested over a dozen different models myself with my two cats, Wessie and Forest. This review was written after using the Litter-Robot 3 Connect in my home for over a year.
Before testing the Litter-Robot 3, I made observations about the product’s design, engineering, and appearance. I assessed the ease of setup, how consistently it worked, and how effectively it controlled odor and litter scatter. I also evaluated my cats’ responses to the Litter-Robot 3 and my own experience using the Whisker app.
Litter-Robot 3 Connect and Whisker Overview
With its distinctive design and large size, the Litter-Robot is a dramatic addition to the home. At night, a blue light illuminates inside of the dome, giving it an even more dramatic appearance. Mallory Crusta / Cats.com
In 2000, Auto Pets produced the first Litter-Robot—an innovative globe-shaped, rotating litter box that automatically sifts your cat’s litter after each use. The third edition of the Litter-Robot, called the Litter-Robot 3 with Connect, is a WiFi-enabled device that allows you to control and monitor cleanings via a smartphone app.
With its glowing blue night light, distinctive design, quiet performance, and smart home-ready functionalities, the Litter-Robot 3 looks like the litter box of the future. It utilizes a weight sensor to detect your cat’s presence in the globe-shaped main body and automatically initiates a cleaning cycle after a preset time delay. You can also trigger the cycle manually by pressing a button on the front of the unit.
During a cleaning cycle, the Litter-Robot’s globe rotates inside the bonnet, sending the litter inside shifting and sliding through a sifter. The rubber liner pops out, ensuring that all of the waste detaches from the sides. Clean litter is collected while clumps are deposited in a sealed waste drawer housed in the base of the unit.
When the cleaning cycle is complete, the globe rotates back to its original position, returning the clean litter to the litter bed for reuse. Waste and dirty litter remain locked away in the waste drawer, which needs to be emptied about once a week in a single-cat household.
Litter-Robot 3 Connect Features
The Litter-Robot 3 Connect is compatible with a smartphone app, available for both iOS and Android devices. This app allows you to monitor your cat’s litter box usage and control it remotely. Mallory Crusta / Cats.com
The Litter-Robot 3 arrives fully assembled and ready for use. You’ll just have to take the ridged rubber mat out of the globe and place it on the step, install a drawer liner, pour in the litter, and then plug the Litter-Robot in. If you purchase the Litter-Robot 3 Connect, you’ll need to take a few minutes to sync it with the Whisker app.
Though easy to set up, the Litter-Robot 3 is a big, noticeable installment in the home. It measures 30 x 25 x 27 inches and weighs 24 pounds. Before you take the plunge, confirm that you have enough open floor space to fit this behemoth.
While some automatic litter boxes, like the PetSafe ScoopFree, demand that you use a specific type of cat litter, the Litter-Robot gives you a few more options. This model works best with hard-clumping litter. Whether you choose clay, clumping crystals, or a biodegradable product, you’ll want something that creates firm, cohesive clumps.

The Whisker app allows you to monitor the waste drawer level and track your cat’s litter box usage. It gives you a daily, weekly, and monthly analysis of your cat’s litter box activity, which can provide valuable insights into your cat’s health. This app also allows you to adjust all of your settings, including the nightlight, sleep mode, and cleaning cycle delay timer.
What We Like
- It’s one of the most versatile and consistent automatic litter boxes you can buy.
- The design gives you the freedom to choose any clumping litter (though it works best with hard-clumping clay).
- Its sifting mechanism works more reliably than many other self-cleaning models.
- The Whisker app enables you to track your cat’s litter box activity and remotely monitor and control the litter box.
- It takes the work out of scooping, which can benefit people who are busy or have trouble cleaning the litter box due to disabilities or mobility issues.
- The sealed waste drawer does a good job of containing litter box odors.
What We Dislike
- It’s one of the most expensive automatic litter boxes on the market, priced around $500.
- Performance may vary depending on the type of cat litter you use.
- It takes up a great deal of floor space and should be placed away from walls and corners.
- The interior may be too confining for large cats.
- It still requires occasional disassembly and cleaning to maintain optimal performance.
What Did Our Test Cats Think?
My 14-lb cat, Wessie, would use the Litter-Robot if he had to, but he was reluctant to use it on a regular basis. The dome is small and confining for larger cats. Mallory Crusta / Cats.com
I found the Litter-Robot incredibly easy to set up and it paired quickly with the Whisker app. Both Wessie and Forest were hesitant to use the Litter-Robot when it first arrived.
Over the months of trialing the Litter-Robot, my larger cat refused to use it. I believe he was uncomfortable with the small internal size of the globe. Though it’s a massive unit that takes up a lot of space in the room, the inside of the Litter-Robot measures just 14 x 14 inches.
My smaller cat took to the Litter-Robot readily. I believe the Litter-Robot appealed to her size and personality. As a lightweight cat with a delicate frame, she fits easily inside the globe. Because it’s cleaned after every use, the Litter-Robot appeals to her love of cleanliness. It also suits her appreciation of cozy, confined spaces.
Unfortunately, I wasn’t able to get much out of the app because one cat wasn’t using the Litter-Robot and it wasn’t consistently detecting the other cat. I could adjust my settings from the app and monitor the waste drawer, but I missed out on the usage tracking.
I found the Litter Robot’s sifting mechanism was consistent and effective. Because it allows the litter to fall through a grate naturally, the Litter-Robot avoids some of the jamming and clogging that plagues other self-cleaning boxes that use rakes and conveyors to separate clumps from loose litter.
Odor Control and Litter Scatter
Whenever I pull out the waste drawer, I’m surprised by how much stench is locked away. The smell is fully contained in the drawer until you open it up, meaning that the house feels fresh. Between this effective containment system and the Litter-Robot’s frequent cleaning cycles, it’s better at controlling odors than any traditional litter box.
The Litter-Robot comes with a little mat that’s supposed to capture litter, but it’s pretty small and doesn’t catch everything—especially if you have cats who dig a lot. If you want to prevent all of that scatter, you can put a mat in front of or underneath the Litter-Robot for additional protection.
Choosing the Right Litter
When I first got the Litter-Robot, I used fine-grained, lightweight clumping clay that resulted in a sticky mess. Later I tried Fresh Step, Tidy Cats 24/7 Performance and Dr. Elsey’s Ultra. All of these hard-clumping clay products worked well, creating firm clumps and allowing the Litter-Robot to do its job with minimal sticking.
I also tried the Litter-Robot with a couple of biodegradable litter products, including a grass-based litter and World’s Best Litter, which is made from corn. Both had more sticking than I’d prefer, fusing a bit to the rubber liner.
Pouring in the litter comes with some challenges. Large litter bags and boxes don’t do well with the small opening and angle of the Litter Robot’s entryway. You’ll have to use a scoop to transfer litter from bag to bed.
What Do Customers Think of the Litter-Robot 3 Connect?
Since 2000, Litter-Robot has sold over a million litter boxes. The Litter-Robot 3 Connect alone has around 15,000 customer reviews on the Litter-Robot site. It has an average 4.3 rating out of 5 stars with over 10,000 5-star reviews.
Positive Reviews
“I have had the Litter Robot 3 Connect for three years now after trying another rake-style auto-cleaning litter box that was terrible. I tell everyone I know who has a cat they need to get this. It is a game changer.”
—Renee, Litter-Robot.com on November 12, 2023
“This is the best litter box!! A dirty, smelly box and trying to remember to clean it regularly were two big pain points in our home. This is totally worth the investment. It works flawlessly and our cats took to it very quickly. I will never go back!”
—Julie D, Litter-Robot.com on November 8, 2023
Customers are overwhelmingly satisfied with the Litter-Robot III, so much so that many return to the site years later to provide an updated review. Many positive reviews mention the Litter-Robot’s strong odor control, ease of use, and convenience.
Negative Reviews
“I have to reset or power down and power back on literally every day—sometimes a few times a day. Also, the fill gauge is extremely skewed. I’ll put in a new liner and a few hours later, it’ll say it’s 95% full. If I’m having to do this much work to not scoop, I might as well scoop.”
—Erin, Litter-Robot.com on November 8, 2023
“It worked amazing for a while, but in the past few months, it has not cleaned itself without me manually cycling it. I’ve read and tried everything I could to fix it and it won’t work the same anymore. These things are way too expensive to stop working after only a couple months.”
—Trinity, Litter-Robot.com on July 8th, 2023
While customers are largely satisfied with the Litter-Robot initially, a significant number of negative reviews mention that the unit begins to glitch or stop working after a few months or years of use. Some of these issues appear to coincide with the release of the Litter-Robot 4 and the subsequent redesign of the Whisker app.
Sensor issues also appear to be common when using the Litter-Robot. Many users say that the sensor was unable to detect their cats, even though they met the weight minimum and had placed the Robot in an appropriate location. In my experience, the Litter-Robot only detected my larger cat when he went into the box.
How Much Does the Litter-Robot 3 Connect Cost?

The base model Litter-Robot 3 costs $499 on the Litter-Robot site. If you opt for the Connect version, you’ll pay $549. Whisker offers refurbished models at a discount, but availability is inconsistent. Shipping is free to the contiguous United States and financing is available with Affirm.
The Litter-Robot 3 Connect comes with a 90-day in-home trial as well as a one-year warranty. You can extend the warranty to three years for an additional $100.
Whisker offers an assortment of accessories for the Litter-Robot, such as litter mats, extra waste drawer liners, clumping clay cat litter, and an OdorTrap Pod. You can also purchase the Litter-Robot 3 as part of a bundle with various accessories.

hello, I have been looking for places where I can cultivate honest conversations about this very expensive auto cat box…I have a male cat that likes to get into the high sided boxes I currently have and position himself in a horizontal manner. Therefore, he often pees on the side of the box. Sometimes, he raises his little hiney and pees on the side of the box. Sometimes, I am able to get the litter scooped up on it…but regardless, this leaves a “trail of pee.” I dump my boxes and wash them litter boxes about every 2 weeks. Currently, I mix Boxie Cat and Dr. Elsey’s litter. Both of my cats are rescues and seem to get more “feline herpes or sinus stuff” if I let the boxes go much longer than that. I do offer them different quality supplements, and they eat Primo food.
I would love to save time and maybe one day money if the machine held up well. But I am concerned about his potty positioning habits. What do you think would happen w/this litter robot and my sometimes side pee-er??
I have been very wary about the purchase because I am worried I will just have to clean it every two weeks anyway. Also, I have seen some youtube videos of owners having issues w/the mechanics. And, for such an expensive item, the warranty is not even 2 years and the return policy seems possibly concerning…but I am not fully sure about that.
Thank you for your time and help and also for referring me to any other places I may be able to discuss my questions and concerns about this mammoth item! lol
Sincerely,

Hello Mary, thank you for commenting! The Litter-Robot’s open front could absolutely be an issue for a cat who tends to urinate on the side of the box. As for your concerns about cleaning the box every two weeks, it’s hard to say. I’ve found that the Litter-Robot stays fairly clean provided that you’re using a good litter and there is generally less accumulation since the waste is scooped a few minutes after each use. As for the mechanics, that is a valid concern. I’ve encountered sensor issues and other users have reported mechanical issues cropping up after the warranty has expired. You may enjoy discussing your concerns with the community on our Litter-Robot video review: https://www.youtube.com/watch?v=5i8muFdG5Og
I just received my litter robot thru affirm yesterday . My cats used it about 14 hours later. I was so glad they used it and afterwards as it rotates they sat and watched it. It was so cute they seem to be ok with it so far so I’ll see in the next few days if it goes well or not. I’m praying that it will be no problem.
I think its well worth every dollar. I was so tired of waking up at 3am to scoop poop and take it outside to the garbage. I’m glad thats over. Hoping for the best this robot has to offer at 500.00$
Hi Laura, it’s good to hear that your cats are okay with the Litter-Robot thus far, and I hope that it continues to work well for you and proves to be a good investment. Thank you for sharing your experience! – Mallory
Hi Mallory!
I love your reviews, they are so helpful to a first time cat owner like myself. Would you please review the Petkit Pura X? Ive been trying to decide between the Petkit or the Litter Robot and would love to see a full review on it so I can make my decision. Thank you!
Hi Aeryn, thank you for commenting! Yes, I plan to review the Petkit Pura X very soon. It’ll probably go live on the YouTube channel first, so if you subscribe and accept notifications, you’ll get the notification when that video goes live. It’s scheduled for November.
I have purchased three litter robots, one as a present and two for myself. I have many rescue cats and many litter boxes. But the two litter robots really helped with regular scooping… That is, for a little bit. I started having issues with the first one and was all over YouTube looking for videos to try and fix issues. I would get it working for a while and then it would stop again. The second litter robot never worked right from the beginning. I have numerous complaints and calls in to customer service to try to fix these things and they keep generously sending me parts that take weeks to get here, but then you have to take the wires apart and reinstall new mechanical yourself. Have done this multiple times with multiple issues. After self-repair the litter robots don’t work at all. They just flash some series of Lights for which the customer service agent wants to send you more parts. It takes a long time to take these things apart and it’s infuriating when nothing works. These are now $700 (ridiculous amount of money) to only work for a few months. I can’t tell you how infuriated I am right now. Today was the last straw. I’m packing both of these things up, only one of which is still under warranty and I’m sending them back. At this point I don’t care what they do with them. They take up a huge amount of space for very little yield. I would highly not recommend buying these. Unless you only need a temporary solution for a few months. As soon as the warranty is over they break and the only thing you can do is send them back for a $200 refurbishment. Save yourself the headache.
Hi Christina, thanks for the comment—it’s always helpful to hear about the malfunctions and other issues encountered by Litter-Robot users.
I’ve had the same issues. Very frustrated. Having to babysit it to make sure it’s not stopped in the middle of a cycle for hours so my cats have a box defeats the purpose.
I loved mine for the first year or so, until like others, it would just stop and flash random lights. They have sent me 2 replacements bases, and the second one is now doing the same thing. Customer service is AWFUL….cannot talk to a human being, and it takes them weeks to send new parts. Now they were kind enough to tell me that I am no longer under warranty, but they will be DELIGHTED to sell me a new unit. I think not. For what it costs, it should work longer, and the company should provde exemplary service. DO NOT WASTE YOUR MONEY.
I bought my litter box 2 years ago. I have 2 cats. It was the only box that self cleaned at the time, costing a huge amount of money £500. It worked well at the beginning. I have to say that it wasn’t easy doing a deep clean, it’s a long process, it needed deep cleaning as the build cat urine smells was unbearable. I also found that the cat litter never really cleaned properly and stuck to the liner and I always had to clean it manually. Problems started about 6 months ago with several issues. I have tried, family members have tried to repair the box.Parts are so expensive. Customer service is next to impossible. About a month ago I literally had enough and have now reverted back to the old way.
I wouldn’t recommend purchasing this product. Once the product starts failing it’s a knock on effect with something else not working.
What I would like to say is there is plenty of Ytube tips to help but this company should setup a repair service in the UK with a minimum rate call-out fee.
After 4 years we had been having issues and having the app I found a constant issue of the bonnet being removed during cycles. All I had to do was move the bonnet and the cycle would continue. I bent the tabs out to gold it better and it didn’t help. When I took clear 2″ packing tape and taped the bonnet to the base about an 1nch forward of the back, about 2″ behind the tabs, the error went away. We are very happy with our litter Robot 3 and I believe it will last for years more. The full sensor needs to be cleaned every couple of years, but that doesn’t take much to do and not scooping the litter is priceless.
Definitely get the warranty. Mine worked for almost a year. And no matter how clean or how many times you fix it, it continuously malfunctions. I will be sending mine back. Not worth the stress.
Hi, I’m very interested in getting the litter robot and reading your review has convinced me it’s worth the money. I’m 71 and have COPD so it has become hard to scoop as often as needed. I’m sure my cat will be okay with the robot because he already uses a covered litter box. But everything I’ve read so far I don’t know how often you replace the litter. I have used Arm & Hammer Slide litter so I believe it will keep the mess to a minimum.
Thank you for your help.
Karen
Hey there Karen, that’s a great question. I would change out all of the litter about once a month, similar to with a regular litter box full of clumping clay. Hope it works for you! – Mallory
I GIVE UP!! I have been using the Litter Robot for about 6 months and I am over trying to solve for all the issues it has created. My two cats took to it readily, however, my 17 year old does not turn around when he gets in and urinates above the litter line. This results in a smelly and gooey mess. He then aggressively covers it showering litter and urine soaked litter goo outside the box – even on the adjacent wall. He gets it in his paws which he then tracks in the carpet and on my bed! I have had more hands-on contact with cat excrement since I bought this device than I ever had scooping litter! I never had this issue with the traditional litter box. I have tried several different types of litter and am still having the issue. Clumps of litter also stick to the rubber liner and, somehow, to the top of the globe resulting in more mess for me to clean up and it smells bad – I am constantly scraping litter off the inside roof! I have pictures. Litter Robot customer service was very nice and recommended I use a different type of litter, extend the time until it runs to allow the litter to soak up the urine and purchase the little gate to prevent the scatter. I tried it all. The gate immediately got covered with litter residue and I had to clean it too. The Litter Robot is very large and takes up a lot of room. It is a little high for my old man cat so I bought the steps which I thought would help him get into the box. He is insecure on the steps and tries to jump over them getting in and out and now is urinating outside the box! In 17 years he has never done that before…….it concerned me so much that I took him to the vet to make sure he didn’t have a urinary issue – thankfully he does not. This was a very poor investment and I tried hard to make it work but, since it has been over 90 days, I will not get my money back if I wish to return it – plus I would have to pay shipping! I cannot believe that I am the only one having these issues. The mess is just too much to deal with so…I GIVE UP!!! Scooping doesn’t seem so bad after this experience….
Julie, that experience does sound very frustrating. It does sound like you’ve tried everything you could. You may be able to get some more insights or even sell the unit if you join the Litter-Robot support group on Facebook.
I had a first generation liter robot that worked great. I bought the new one when it came out and gave my old one to a friend. I hate this new model. The thing is always stopping half way. There is a lame paddle thing inside that does nothing but get poop on it. And the weird plastic jacket thing keeps coming off. Bad design all around.
So disappointed
Julie,
Your post, while awful, made me laugh until i cried. I have a cat that does the exact same thing.
Thank you and I am sorry it has been so frustrating.
Cheryl
Don’t waste your money on these hugely overpriced pieces of junk! Our LR3 has just completely died…YET AGAIN!
Forgot how many times I have spoken and dealt with customer support since owning this and what is extremely frustrating is that they do not maintain a database of you as a customer so every time you contact them you have to give them all your personal information and LR information and serial number like you are calling for the first time.
We have had a complete LR3 warranty replacement, set of sensors for full litter tray, and now a complete new base under warranty.
We are at the point now where the thing will not function without going into some kind of fault mode such as litter that full when it’s empty and pinch bar error.
Totally fed up with going through the same troubleshooting checklist only to find nothing works, unless they send you a new replacement.
The litter robot stinks too, we had less odor with traditional litter trays. The problem is the plastic they use, the odor eats into it and you simply cannot get rid of the smell so matter how often you clean it the odor has etched into the plastic.
Worse product I have EVER bought…period
Sorry to hear you’ve had so much trouble, Craig! I had a few issues with mine as well – similar things like the error messages and it sometimes would just dump all of the litter into the waste drawer instead of separating out the waste. I found that it helped to do a thorough cleaning in some cases (not all), but I’m sure you’ve tried all of that.
It’s super frustrating that the only option is to get a replacement – I imagine it takes a lot of time! I hope your latest replacement works better for you.
I got mine in December of 2021, and in the last month, it has stopped cycling 3 times. I purchased my litter robot since I received a lung transplant, I think I made a bad decision. Customer service is the absolute worse, they charge so much for this product, yet they can’t hire more people to answer the phone. Frustrating…
That’s disappointing, Daniel. I’m sorry to hear that you’ve had that experience—the Litter-Robot is definitely prone to malfunctions, and the poor customer support you’ve received definitely adds insult to injury. Hoping you can get this sorted out.
I bought one several months ago. It had garden varety issues from the start. But then, 3 weeks ago the flashing yellow light occured. There was nothing wrong with the anti-pinch, I even replaced the anti pinch contacts spending $15 of my own money. I tried contacting customer service, and the voice message says they will not repond due to high call volumes. I tried emailing customer service to no avail. This is the worst customer service I have ever seen!! After all these weeks I have a litter robot that does not work, I have no hope of refund, and no hope of getting it working, it should be renamed as the the “Litter F***BOT” I will never again buy this piece of crap.
That’s terrible. I’m sorry to hear you had these issues so quickly. To be clear, you bought a Litter-Robot 3, right? I know these problems are common, but that happening within the first few months of use? That’s dreadful. You should definitely have heard back from their support team by now.
Can not get cat to go inside of the Litter Robot 3. Do not what to do. I have put cat treats on all the steps and put wet food on a plate and sat it inside the LB3 but will not go in it. Suggestions please.
Perhaps focusing on food enticements is the wrong approach! I would think about putting your cat’s waste from the old litter box in there instead. Make sure that you leave the Litter-Robot turned off at all times when you’re starting out, and let waste build up in the old litter box(es) to make it less appealing to your cat.
I have all these issues..,. customer service no help..i am not going to order parts or send it back…. liked it when it works right.,now apart cleaned and still won’t work.. only had 10 months….can i get my money back
