If you’re looking for the best automatic cat litter boxes, I’ve got you covered!

Today, we’ll cover the biggest names in the robotic litter box world and find out what makes them so popular. 

Read on for in-depth reviews on each of these machines!

First, though, let’s talk about what to look for when choosing your self-cleaning litter box. 

Let’s get started!

If you're looking for the best automatic cat litter boxes, I've got you covered! Check out the top 5 and find out what makes them so popular!


What to Look for in the Best Automatic Litter Box

How big is the usable size?

While the overall size matters, you really want to hone in on the internal size- the part your cat actually uses (hence, usable size).

That goes for any litter box, but robotic boxes make it a little confusing because they look so huge on the outside.

Remember, a large part of the box is dedicated to the machinery that makes it robotic in the first place!

As you scroll through descriptions, look for words like “cat potty area” or “internal dimensions” to find out how much space your kitty has to do his business.

While bigger isn’t always better, you want to make sure your cat has enough room to stand, turn around, and dig.

How “hands-free” is it really?

Why do you want an automatic litter box in the first place? To cut down on the amount of time you spend scooping poop, I bet!

So, you want to look for a litter box that handles waste efficiently and doesn’t leave behind a bunch of clumps that still have to be scooped!

You also want something with a good collection compartment. Preferably something that lets you either dump and go, or just pull out a bag and toss. 

What kind of litter does it use?

While one of the boxes below does use special crystals, ideally you’ll want something that can handle your preferred litter. 

Whether that’s clumping, clay, crystals or corn cobs is up to you. We all have our own ideas on the best cat litter!

Ideally, you’ll want a box that can take different types, just in case you need to (or want to) switch things up later. 

How easy is it to put together?

Even the best automatic litter box is worthless if you never get beyond the assembly stage, right?

Only you know your “assembly patience level,” so “easy” really is all relative.

I always read through reviews to find out how many people complained about the process because I have about zero assembly patience. 

I’ve been known to burst into tears while putting together a simple plastic shelf! 

You also want something that’s easy to take apart again!

Why? Well, first, you’ll need to clean all of the parts at some point. Second, you may need to replace something at some point and should know that it’s feasible. 

How loud is it?

Consider this: if you think the box is loud when you’re standing next to it, imagine how noisy it is to a cat sitting inside of it!

A box that’s too loud will freak your cat out and they won’t want to use it.

Plus, if you have multiple cats, do you really want to hear a motor whirring a zillion times a day?

Now that we know what to look for, let’s check out my picks for the top 5 best automatic litter boxes!

One quick word about the specifications for each box: cleaning frequency depends on how many cats you have. I gave the average time between cleanings. 


1. Litter Robot III Open Air Review

The Litter Robot III Open Air is definitely the most highly-rated robot litter boxes, but it’s also the most expensive by a long shot. 

Let’s talk specifications, pros and cons to find out if it’s worth the cost. FYI, you might also see this called Litter Robot 3 (instead of the Roman numerals) as you shop. 

Important Specs

  • Overall Size: 29.2″ x 24.1″ x 26.7″
  • Potty Area Size: 17″
  • Type of Litter It Uses: Any clumping litter
  • How often does it need to be emptied: About once a week, depending on how many cats you have. 
  • Ease of Assembly: No assembly required, so pretty darn easy!
  • Warranty: 18-36 months

Features & Pros of the Litter Robot III

  • Uses a patented self-cleaning method that relies on gravity to get the job done. 
  • No more scooping, ever! Thanks to the collection system, you just slide out the waste drawer and dump it when indicated. 
  • Total odor control, since it removes the waste right away and tucks it behind a carbon filter in the collection drawer. 
  • Suitable for up to four cats, providing them with fresh litter every time they use the box. 
  • Large enough for cats up to 25 pounds, which makes it perfect for a Maine Coon. 
  • 90-Day in-home trial to see if you like it. If you don’t, send it back with no questions asked. 
  • Also has a WI-FI “Connect” version that actually lets you track your cat’s potty habits. 

►►►Check out the video below to see how it works◄◄◄

Cons of the Litter Robot III

  • The most obvious con is the price. It’s the most expensive automatic litter box on this list by a long shot. 
  • It’s fairly bulky, so you’ll need a lot of space for it. Definitely not a space-saver litter box!
  • You need to use a very exact amount of litter for optimum performance, and it’s tricky to figure out just how much that is. 
  • Replacement liners are pretty costly for what they are. A pack of 20 will run you $25, which is like paying $1.25 for what is essential a tiny garbage bag!
  • Replacement components are on the expensive side. For example, two small rubber seal strips will run you $12.99, and need to be replaced about twice a year. 


While this particular automatic litter box is out of my reach because of the price, it’s pretty much the “dream machine” for those who can afford it!

In fact, it’s the highest-rated by quite a large margin! While most robotic litter boxes fall between 3-4 stars with customers, this one hits the high 4 to 5 star mark every time. 

It’s also the only litter box I could find that offers a WI-FI version. It’s about an extra $100 though, so you’ll have to decide if it’s worth it. 

One thing to keep in mind, though: make sure you can afford the litter box AND the upkeep. Take note of the cons. Replacement liners and parts aren’t cheap.

  • Automatic MoonGlo NiteLite (Blue Led)
  • Drawer Full Indication
  • Self-Adjusting Cat Sensor
  • Large Upward Facing Entry for 'Open Air' Feel
  • Suitable for cats of all sizes


2. PetSafe ScoopFree Ultra Self-Cleaning Cat Litter Box Review

The ScoopFree Self-Cleaning Litter Box is one of the most popular budget-friendly automatic litter boxes on Amazon. Let’s find out why. 

Important Specs

  • Overall Size: 19 1/8 in. W x 27 5/8 in. L x 6 3/8 in. H
  • Potty Area Size: 14 in. W x 15 1/2 in. L
  • Type of Litter It Uses: Proprietary disposable tray with crystals
  • How often does it need to be emptied: Change tray about every two weeks
  • Ease of Assembly: Super simple, just pop the hood on and slide the tray in place. 
  • Warranty: One year, but only for manufacturer defects

Features & Pros of the PetSafe Automatic Litter Box

  • Crystal litter is 99% dust-free, which is good for you and your cat. 
  • Simple to clean, just remove the tray and toss it. 
  • Adjustable cleaning delay. You can set it for 5,10 and 20 minutes. 
  • Virtually odor-free, thanks to the crystals and the tray system. 
  • Available with or without a hood, so if you have a larger cat you can go for the hood-free system. 
  • 10-foot long cord lets you place it pretty much anywhere and not just up against an electrical outlet. 

►►►Check out the video below to see how it works◄◄◄

PetSafe ScoopFree Cons

  • Uses proprietary litter, and a 6-pack of replacement trays costs more than half the price of the system to begin with. 
  • Multi-cat homes end up replacing the litter significantly more often than single-cat homes, which means you’ll be paying even more money in the long run. 
  • The rakes that move the litter tend to get rusty. 
  • Cats who really dig in their boxes can completely wreck the cardboard tray. They do sell a permanent tray to combat this, but it’s kind of pricey.


After the Litter Robot above, the PetSafe ScoopFree system is the most highly rated among customers, making it an idea budget-friendly option. 

While I don’t love the fact that it uses proprietary litter, when you consider the cost of regular clumping litter compared to how often you change it, it actually works out okay. 

PetSafe ScoopFree Ultra Self-Cleaning Cat Litter Box, Covered, Automatic with Disposable Tray, Purple
  • SELF-CLEANING LITTER BOX: Self-cleans for weeks with no scooping, cleaning or refilling
  • UNBEATABLE ODOR CONTROL: Crystal cat litter absorbs urine and dehydrates solid waste to remove odors; covered trap locks away solid waste and odor so you never have to touch or see smelly waste
  • LESS MESS: Low-tracking crystals don't stick to your cat's feet and are 99% dust-free
  • LEAK PROTECTION: Plastic tray lining creates a powerful extra barrier to help protect against leakage. For indoor use only
  • EASY, CONVENIENT CLEANUP: No scooping required; simply remove the disposable litter tray and throw it away
  • PEACE OF MIND: Health counter tracks how many times your cat uses the box and safety sensors automatically reset the rake timer if your cat re-enters the box
  • EXPERIENCE: PetSafe brand has been an industry leading U.S. manufacturer of pet behavior, containment and lifestyle products since 1991, helping millions of people and pets each year


3. Omega Paw Self-Cleaning Litter Box Review

Let me make something clear up front: the Omega Paw Elite Self-cleaning Litter Box is NOT a robotic litter box. 

So, how does it make this list? Read on to find out exactly HOW it self-cleans.

View this post on Instagram

Update: Ashby is now happily laying in the dirty litter box. 🤦‍♀️ We had some questions yesterday about the litter box and the litter we are now using. This is not an ad. We are just happy customers sharing a positive experience. After Baby Mouse’s asthmatic episode last month we needed to change out anything that could irritate his breathing, which meant switching to an unscented, dust-free litter. After many suggestions from all of you, we decided to try the Dr. Elsey’s Precious Cat Ultra Clumping litter. The odor control is very impressive and we have found it to have significantly less dust than the Tidy Cat we were using. Our boys love to play in the litter and kick it out of the box, so you can see there is litter on both mats and they do track it through the room. Honestly, I’d rather have that than the litter dust everywhere, so I’m counting this as a win. We were using two XL covered litter boxes before, but switched one to this Omega Paw Roll’n Clean Self-Cleaning litter box and we are in love! Guys, it’s so easy! You roll the litter box over, roll it back, and all the clumps fall into the drawer. You just pull the drawer out and dump it. No scooping! We liked it so much that we bought a 2nd one and as you can see it has the Ashby seal of approval. 😊 Also, thank you @chewy for having super fast shipping and great prices. #notanad #justahappycustomer #omegapaw #drelseys @drelseys #chewy

A post shared by Ashby, Séamus, and Pudge (@chaplin_ashby_andcompany) on

Important Specs

  • Overall Size:18.5 x 21.5 x 20 inches for the Elite, other models are a bit smaller
  • Potty Area Size: Unclear, but the opening is 8.5″ wide by 9″ high 
  • Type of Litter It Uses: Any clumping litter
  • How often does it need to be emptied: About as frequently as you’d empty a non-clumping box
  • Ease of Assembly: Somewhat challenging to get alignment just right
  • Warranty: Unclear. You have to request it from customer service, which doesn’t bode well. 

Omega Paw Self-Cleaning Litter Box Pros

  • Since it uses a roll and clean system versus electricity, it has zero impact on your energy bill. 
  • No need to worry about plugging it in anywhere, either!
  • No scooping required. Just roll it over, then back into position. Clumps go into the waste container and clean litter goes back into the box. 
  • Easy to clean, just pull out the drawer and dump it into the trash. 
  • No proprietary waste bags or liners!
  • No motor means it’s as quiet as a traditional litter box. 
  • Since it looks more like a regular box, your cat is less likely to reject it. 


►►►Check out the video below to see how it works◄◄◄


  • The obvious con: it’s not a robot, so it’s not really “self-cleaning” in the sense that it will automatically sweep away waste. 
  • It’s on the bulky side, so you’ll need a good chunk of floor space with extra room for rolling it. 
  • The internal compartment is a bit on the small side, making it a bad choice for large cats. 
  • A good chunk of customers complain that it’s hard to align just right, which results in both litter and odors escaping during the roll. 
  • The seals aren’t tight and urine can escape through them if your cat pees high. 


If you have a petite cat and a small budget but still want something that mostly self-cleans, this is a great option.

While it’s definitely pricier than the average plain old litter box, it’s about half the cost of the cheapest automatic box. 

I actually had one of these many years (and many models) ago. I liked it but eventually replaced it because it wasn’t large enough for my big kitty. 


Omega Paw Elite Self Cleaning Roll 'n Clean Litter Box, Midnight Black, Large
  • Elite Self cleaning EL-RA20-1
  • Features chrome accents
  • Built in "litter step" catches litter as cat exits
  • New improved clip design
  • Stronger more durable sifting Grill


4. Cat Genie Litter Box Review

We can’t deny that the Cat Genie Self-Flushing Litter Box is definitely the coolest looking automatic litter box, but does it really work?

More importantly, HOW does it work? Let’s check out the specs, pros and cons to find out!


Important Specs

  • Overall Size: 19.25″x24.5″x21″
  • Potty Area Size: 17″ wide
  • Type of Litter It Uses: Proprietary Cat Genie Washable Granules
  • How often does it need to be emptied: Never, but you do need to clean the unit every couple of months
  • Ease of Assembly: A bit challenging since it needs to be connected to a water line and some sort of waste system (see cons section)
  • Warranty: 2-year, limited to manufacturer defects

Cat Genie Pros

  • Zero contact with waste and zero regular cleaning required since waste gets flushed away. 
  • It’s probably the coolest litter box you’ll ever see!
  • Small enough to use in apartments. 
  • Reusable litter cuts down on the amount you have to buy. 
  • Uses environmentally friendly litter. 
  • The washable granules are also good for cats with sensitive skin or allergies. 


►►►Check out the video below to see how it works◄◄◄


  • You’ll need to hook it up to a water supply, so you’re limited on where you can place it. 
  • You also need to “connect” it to your toilet or laundry machine waste line so that the waste can get “flushed” away
  • A rather significant number of customers complain that the machine malfunctions and ends up “baking” your cat’s poop. 
  • Taking it apart to clean it is kind of a pain and you’ll need to do it pretty much monthly. 
  • It’s only ideal for 1-2 cats, and not large enough for big kitties like the Maine Coon. 
  • It’s rather loud!


I’ll be honest here, even though I think it’s the coolest litter box I’ve ever seen, this one isn’t for me. First, I have three cats, and two are rather large. 

Also,  the setup requirements make it a challenge for me. I don’t really have space next to my toilet or in my laundry room for the unit, even if it is compact. 

However, if you have one kitty, the space near your toilet, and want something that you rarely have to clean, it may be a good choice for you. 


CatGenie Self Washing Self Flushing Cat Box
  • Automatic cat box flushes waste away and washes itself clean
  • Uses litter-like Washable Granules not clay litter to satisfy cats need to dig and cover
  • Ideal for 1-2 & no more than 3 cats of average size and 6 months or older
  • Requires hookup to cold water and electrical outlet
  • Includes recyclable SaniSolution cartridge and 1 Box of Washable Granules. CatGenie is 19.25inches wide in front, 16inches wide bottom back, 17.5inches top back, 21inches high, 24.5inches deep allowing for hoses. Water Supply Hose 8feet long, Drain Hose 10feet long


5. LitterMaid Automatic Litter Box Review

The LitterMaid comes in a few different sizes, but we’ll be talking about the Single Cat Self-Cleaning Litter Box since that has the highest overall ratings. 


Important Specs

  • Overall Size: 10 x 17.8 x 24.6 inches
  • Potty Area Size: About 14″ x 16″ depending on the model
  • Type of Litter It Uses: Any clumping litter
  • How often does it need to be emptied: While they say up to a week, expect to empty it about every 4 days. 
  • Ease of Assembly: Very easy (remove from box, load the tray, add the filter, and you’re done)
  • Warranty: 1-year, limited to manufacturer defects

LitterMaid Features & Pros

  • Automatic rake that sweeps waste away and into a waste compartment. 
  • A carbon filter keeps odors in the compartment where they belong. 
  • High walls prevent litter from scattering all over the place. 
  • Paw-cleaning ramp keeps litter from tracking outside the box. 
  • Cleans itself for up to a week before you have to get involved and empty the waste compartment. 
  • Fairly inexpensive compared to other automatic litter boxes. 

►►►Check out the video below to see how it works◄◄◄


  • Designed for cats under 15 pounds, so you can’t use it for a Maine Coon or other large-breed kitty. 
  • Newer models tend to have more complaints about not lasting as long compared to older retired models.
  • Waste receptacle lids don’t always stay put properly. 
  • Not designed for cats that like to dig down to pee. 


LitterMaid used to be one of the best automatic cat litter boxes, so I was surprised to see how many poor ratings it has now.

We owned one years ago but it’s not big enough for my current cats. However, we never had issues with the old models. 

Although it’s only a 3-star machine, it still ranks as one of the top 5 best automatic litter boxes. Everything beyond this barely hits the 2-star mark, to be honest. 

It’s a good option for small cats and a small budget. 

LitterMaid LM680C Automatic Self-Cleaning Classic Litter Box (LM680C)
  • SINGLE CAT SELF-CLEANING LITTER BOX: This litter box has automatic scooping with a rake that removes waste for a clean, fresh start. It is designed for a single cat under 15 lb
  • LOW MAINTENANCE: When used as directed, the LitterMaid Single Cat Self-Cleaning Litter Box requires no daily scooping, meaning you have a scoop-free clean up for up to 7 days
  • ODOR CONTROL: Once the rake removes waste, the waste receptacles with carbon filters keeps mess and odor contained
  • LITTER BOX DESIGN KEEPS AREA CLEAN: Designed with high walls to prevent litter scatter and a paw cleaning ramp to help prevent tracking around the box
  • ACCESSORIES INCLUDE: 4 waste receptacles, 4 carbon filters, 1 scoop and rake cleaner, 1 paw cleaning ramp.Use the scoop to evenly distribute litter in the litter tray

Final Recommendation

The Litter-Robot is #1 by leaps and bounds, so if you have the budget for it, I would definitely go with that one! 

However, not all of us have $500+ to spend on a litter box. For those on mid-range budget, I really think the PetSafe ScoopFree is your next best bet. 

If $150+ is still out of your range, though, I’d go with the Omega Paw. While it’s not technically “self-cleaning,” it gives you the most bang for the least buck.
