Best 8 Automatic Cat Litter Box Comparison Chart


Here you will find the top performers on a side by side comparison, with in-depth reviews describing the pros and cons of each unit. You will see the top winner and why this machine is recognized by people (and me personally), as the best on the market. But first, you must know the 7 main features you need to look for when choosing the best auto litter box, so you don’t make mistakes.

1. Dimension of the waste compartment. This is the first thing you need to pay attention to when getting a self-cleaning litter box. Why? Because the bigger the waste compartment is the longer you will go without thinking about the cat litter box. When the capacity of the waste compartment is small, even if the unit works excellent in self-scooping, you will need to empty the waste tray every 2 or 3 days and maybe every day with 2 or more cats. It’s simply not worth it.

Waste Receptacle

2. How the system handles the urine. Liquids are not easy to contain and collect. When a cat urinates a lot, the automatic litter box needs to have the capacity to absorb the urine and collect the urine clumps efficiently. Some auto litter boxes absorb the urine with crystals, others drain it through a water drain system and others use clumping litter for a scooping rake or a rotating system to collect the clumps. The best self-cleaning litter box should be able to handle a good amount of cat urine.

3. Level of Contact with cat waste. Some automatic litter boxes require a minimum contact with cat waste, while others require some scooping here and there. If you want a minimum contact with waste, get a machine that doesn’t require extra manual scooping.

4. Litter the system uses. Consider that auto litter boxes may use a different type of litter for the system to work. If your cat is not used to the new type of litter your pet will need to adapt to it. You may need to switch to blue crystals or plastic granules or clumping clay litter.

5. Supplies. Some self-cleaning litter boxes need you to buy specific supplies from the Manufacturer for the unit to operate. Check this point if you don’t want to do that.

6. Level of noise. If a motor is too noisy it will not only bother your cat but it will bother you as well. Some cats are really skittish and may reject the litter box only due to its noise. Consider the noise level especially if you are going to place the unit close to your bedroom.

7. How easy is to disassemble it for washing. When it comes to washing the unit we expect all parts to be disassemblable for washing. Some units have built-in pieces that can’t be cleaned easily, they can only be wiped with a damp cloth. Consider this point if you really like to deep wash the litter box.

Top 1 Automatic Litter Box – The Litter Robot III


STRONG ADVANTAGES: High percent of reliability, fully self-scooping, not dirty rakes, saves up to 50% on cat litter, indicator when to empty the litter box, unique mechanism to release all the waste from the bottom, minimum noise, high capacity to collect the cat waste, practically zero odor.

Do you know why this unit is so dependable? Check the main 5 technical reasons why this is the best self-cleaning litter box. You may wonder how I came up with these 5 reasons to place the Litter Robot Open Air on top. I am an owner of a Litter Robot 3 plus I’ve investigated automatic litter boxes for almost 5 years and I consider myself very knowledgeable about how most of them work (actually you will find other review-websites with my reviews). I know every single downfall that most of them have and this unit doesn’t have any of those issues.

  1. Only if your cat is an enthusiast litter kicker some litter could spill out the litter box, but this rarely happens. Solution: to stop litter spillage, get the fence or the ramp, they both come as optional accessories. You can also get an easy to clean litter mat.
  2. If you pour too much litter in the globe, the unit might not complete a rotation. Solution: to allow a smooth rotation you must pour litter only up to the full line indicator (approx. 12-13 cups of 8 Oz).
  3. If you let the Globe go too low on litter, the unit won’t activate to start a cleaning cycle. Solution: Simply top the unit off with litter every week.
  4. Occasionally some litter may fall between the bag and the waste drawer (this hardly happens). Solution: to avoid leaving a gap between the waste drawer and the bag you have to line the bag tightly to the drawer, that simple.
  • IDEAL CAT OWNER:  People that want to forget about the cat’s litter box for several days, up to 10 days with one small cat (personally, I only think about the litter box on Sundays when I take the trash can outside). People with medical conditions that can’t bend over too much to take care of the litter box on a daily basis. A cat owner willing to do a big initial investment but without future expenses on the manufacturer’s supplies.
  • IDEAL CAT: Any cat weighing between 5 and 20 lbs

SPECIAL GIFT FOR CAT LOVERS! If you love the Litter Robot Open Air as I do,  you can get a very good price for it, just check more details on my Litter Robot III review where you’ll see the Pros and Cons of this machine, demonstrative videos with my cat using the unit, tips for better use, and much more.

Note: The Litter Robot Classic and Bubble are the previous versions and are not available on the market anymore. The Litter Robot III Open Air supersedes both, due to the excellent engineering applied to it, making it the top one.

THE TOP #2: 

The third best rated automatic litter box. We could state that the ScoopFree handles the urine until the tray needs to be changed (every 10 to 20 days, depending on the cat) and the feces clumps until the waste trap gets full and then you need to scoop it (every 3-4 days).

ScoopFree Ultra

ScoopFree Ultra

  • ADVANTAGE: Convenient disposable tray system.
  1. The bottom of the unit is a cardboard tray and it may be susceptible to leaking. Solution: For the same reason sidewalls are not fully sealed. This could be a problem with certain male cats. Solution: only alternative option, if your cat scratches the bottom or urinates on walls, there is a plastic permanent tray that can be used with crystals.
  2. Smelly crystals. Solution: you need to stir the crystals every day and place the unit close to circulating air to make the crystals work better.
  3. Waste compartment too full before time to change tray. Solution: waste compartment needs to be scooped before switching to a new tray.
  • IDEAL CAT OWNER: People with the budget to buy disposable trays to keep the unit odor free (depending on the cat, trays have to be changed every 10-20 days with one cat).
  • IDEAL CAT: Small to regular size cats that can handle crystals as litter. Cats that don’t urinate on walls or scratch too much when digging. Cats that don’t eat by-products or have urinary or digestive problems. If you feed your cat corn or wheat based dry food the Scoopfree isn’t going to work the same. Healthy dry cat foods are essential to reduce the amount of waste your cat creates.



TOP #3: CATGENIE (3.6/5)

CatGenie Litter Box

CatGenie Litter Box

The unit needs a work intervention in the house to install it. It fully takes care of scooping and disposing of the waste.

  • ADVANTAGE: Fully self-cleaning and self-disposing automatic litter box.
  1. Excessive granule-litter tracking granules. Solution: granules tracking can be minimized getting the Sidewalls.
  2. Waste drain line and/or impeller gets clogged with cat hair or granules (not always). Solution: Brush your cat often to avoid hair from going into the impeller and disassemble the unit to clean the impeller periodically.
  3. Bad smell during a cleaning cycle. Solution: Set the unit away from living areas.
  • IDEAL CAT OWNER: People who do not want to dispose of waste. People willing to unclog the unit if needed and clean the granule-litter tracking. People that have a 2d bathroom (ideally the garage’s or a laundry room away from living areas) to install it.
  • IDEAL CAT: Small to average size cat with firm stools and that does not shed too much.




This unit is very similar in structure to the SmartScoop litter box, but with a slightly stronger motor and higher sidewalls.

Pet Zone Smart Scoop

Pet Zone Smart Scoop

  • ADVANTAGES: Rake-scooping system does not push clean litter to waste compartment and does not create piles. Good price.
  1. Cleaning does not start. Solution: clean sensors with a soft dry cloth.
  2. Waste stuck behind rake. Solution: power off the unit, lift rake and clean.
  3. Unit struggles through cleaning cycle. Solution: redistribute the litter on the pan, make sure litter level is not too high.
  4. Scooping-rake does not scoop urine clumps attached to the litter pan. Solution: scrape litter pan to scoop urine clumps.
  • IDEAL CAT OWNER: People willing to scoop and scrape the litter pan when needed, pouring litter in the litter box every 3-5 days and leveling the litter daily. People with one or two average size cats and without a budget to buy special extra supplies to make the unit work.
  • IDEAL CAT: Small to average size cats (under 15 lbs.) that are not diggers, cats that use mostly the center of the litter area. Cats without urinary problems.



This model has some adjustments, such as the plastic rake, more powerful motor and the night timer has been removed.

Littermaid Multicat Automatic Litter Box

Littermaid Multicat Automatic Litter Box

  • ADVANTAGE: Good complement in scooping the litter box for a reasonable price. It can be used for two small or medium sized cats.
  1. Rake being stuck. Solution: turn off the unit & clear the areas from the litter.
  2. Feces caught on the rake and tray. Solution: spray silicone or special oleum on rake and tray.
  3. Litter accumulated on the ends of litter pan or behind the rake. Solution: re-distribute the litter and scoop if needed.
  4. Litter spillage when the rake is depositing waste into the receptacle. Solution: use very good clumping litter. Clear litter in edges of the machine.
  • IDEAL CAT OWNER: People that need a complement to scooping, which means willing to scrap the bottom pan to scoop stuck clumps, maintain the unit properly and keep an eye on the machine at least once a day.
  • IDEAL CAT: Small to medium size cats if used by two cats. One cat up to 15 lbs. Ideally cats without digestive or urinary problems and not for extreme diggers. Cats that don’t use corners.


#6 LITTERMAID LM580 (3.1/5)

This model is the return of the original Classic Littermaid that was discontinued though not as durable as the original. The unit seems to be better than Littermaid Elite versions, mainly because of its plastic rake.

Littermaid LM580 Classic series

Littermaid LM580 Classic series

  • ADVANTAGE: It complements the daily scoop for a good price.
  1. Dusty sensors. Solution: don’t overfill the litter pan.
  2. Rake gets stuck and it does not move so the unit doesn’t complete a cleaning cycle. Solution: use Premium clumping litter.
  3. Waste stuck on tray/rake. Solution: spray silicone on tray/rake or clear and re-distribute litter in areas where the rake moves.
  • IDEAL CAT OWNER: Somebody willing to check on the litter box at least once a day and willing to clean and scoop the unit when needed. People that need a complement to a scooping and not leaving the unit alone for more than a day.
  • IDEAL CAT: Small to regular size cats (under 15 lbs.) that don’t create too much waste. Cats with no urinary problems. Cats that use the center of litter area.



The unit rotates constantly at a very slow rate, creating a permanent cleaning cycle.

PetSafe Simply Cleaning

PetSafe Simply Cleaning

  • ADVANTAGE: Good sifting conveyor system to collect the waste.
  1. Litter accumulating under the conveyor. Solution: scoop the excess of litter and redistribute litter around the conveyor and clean the conveyor itself.
  2. Unit making grinding noise when rotating. Solution: check between base and plate to be clean. Conveyor needs to be clean and cleared often from the litter.
  • IDEAL CAT OWNER: People willing to do a daily maintenance on the unit. People with one small size cat that want an extra help from scooping every day.
  • IDEAL CAT: Small size cats weighing 12 lbs. or less. Cast without physical disabilities.


(this video has been 30 minutes sped up into over 1 min. The conveyor lid has been taken off for illustrative purpose)


#8 SMARTSCOOP (3.1/5)

The first brand introducing the innovative concept of rake-scooping and not rake-pushing.

SmartScoop Self Cleaning Litter Box

SmartScoop Self Cleaning Litter Box

  • ADVANTAGE: It collects waste clumps by scooping the surface of the litter box.
  1. It does not collect urine clumps attached to the litter pan. Solution: scrape the litter pan manually.
  2. Clumps fall by gravity into the waste compartment and may fall onto the floor in the process. Solution: place a mat underneath.
  • IDEAL CAT OWNER: People with time to scrape the urine clumps from the bottom of the pan and pouring litter every 3-5 days approx.
  • IDEAL CAT: Small to average cats (under 15 lbs.) that usually use the center of the litter pan. Cats without urinary problems.



Why Your Cat Needs A Reliable Self-Cleaning Litter Box

A self-cleaning litter box not only makes your life easier, it protects your cat’s physical and psychological health. The following 5 reasons tell you why your cat will be better and safer by using a top self-cleaning litter box:


Cats love a clean litter box and this fact influences their behavior enormously. When a cat finds the litter box always clean to do its business he or she is a happier cat. After all, having a happy cat is what every cat owner pursues, right? Your cat will feel confident and comfortable in its territory, plus a litter box that is always clean reinforces good habits in your pet.

When you clean the litter box manually, have you noticed that your cat uses it right away after? This means your pet has been waiting for a clean “toilet”.

Actually, keeping the litter box dirty is one of the main reasons why cats stop using the litter box. Now, imagine if the cat finds the litter box clean AT ALL TIMES, that’s the best gift you can give your cat! Cats are very clean animals and they really appreciate a clean “bathroom” as you would do for yourself.


A dirty litter box with waste sitting for a long time creates a lot of germs that get mixed in the litter. When cats use a dirty litter box these germs contaminate the cat’s paws and this means every time the cat cleans itself those germs will go to the cat’s intestine.

There are several pathogen agents in cat waste that is sitting all day, especially in warm weather. When cats go to do their business in a dirty litter box is like somebody trying to walk in a mining camp; cats try hard to avoid stepping on the clumps sitting there because they love having their paws clean. They are smart. The best automatic litter box will always ensure your cat won’t contaminate his paws with waste.


Some cats are pickier than others when it comes to using the litter box. If you have a cat that sometimes does its business on the carpet, rug, or anywhere else, it may be telling you that he or she hates the dirty or smelly litter box.

Sometimes it’s not a matter of the cat being too picky. As mentioned previously, felines try to avoid standing over clumps while doing their business and this is why cats usually choose the corners in the litter box with the consequences of the typical litter box “accidents”, poop or urine outside of it.

Either way, having a cat that is too picky or a cat that is simply trying to keep their paws clean the result is the same: the cat’s poop or urine will end up in places you don’t want.


If the litter box is dirty the cat will wait and will hold in the urine, sometimes for hours. This situation is not noticed by you, you just see your cat walking around normally as every day and your litter box is “fine” in your eyes, with some clumps sitting in it.

But if your cat uses the litter box right after you clean it, most likely your pet has been holding in the urine and when a cat does that every day for several years, your pet could develop urinary issues. Urine sitting in the cat’s bladder too long means toxins that don’t pass, which could create sludging in the bladder. The same if your pet holds in “poop”, that is very unhealthy for its intestine. You don’t want that for your cat. A top self-cleaning litter box will keep your cat from holding in urine or poop.


If you have more than 2 cats, keeping up with their litter boxes could become a hard task. This means the litter box will be dirty most of the time when 2 cats or more use it. Cats don’t like the waste of another cat in the litter box, they prefer their own scent and if you don’t have enough room to place two or more regular litter boxes this could be a problem.

Two or more cats using the same litter box could lead to territorial issues too. Even if the cats share the litter box with no sign of rejection they are not happy and sometimes one of them will do its business somewhere else as a sign of protest.

The best automatic litter boxes are capable of keeping the litter bed clean always, which means there is no problem for cats to share one and you save room in your house by using only one unit as well.

    We got a litter-robot and I’ve gotta say we’ve been loving it! The cats started using it with out much trouble and its saved us tons of work. I’d recommend any cat owner who hates scooping poo (everybody :P) gets one

  2. Debra Dean says:

    I have two outdated one of them discontinued littermaid automatic catboxes. I love them except for the droping of litter outside of the catch box at the end of scopping.Still trying to figure that out. I will try the silicone spray suggestion very soon. Thanks for the idea.

  3. Shawn Jones says:

    I’ve owned a cat genie for years now and I am surprised that it’s still the only fully automatic on the market. The main issues covered above are true, litter tracking and the rare pootastrophe are the major issues. If I averaged it out it would equate to one major maintenance issue each year which entails a complete breakdown of the unit followed up with a thorough cleaning. The litter tracking is the only issue the company hasn’t worked out, and no don’t try your own substitute litter just no don’t do it … Not once should you entertain that idea … No.

    • Lorena Ávila says:

      Thanks Shawn for your input, your experience with the unit will help people to decide with more information. Thanks again!

  4. Eva says:

    I am considering the cat genie, but am worried about having to clean it when it gets clogged. How difficult it is to clean the impeller to prevent the unit from clogging? Is there a video showing this? We have three cats, of which one ragdoll (long hair!) and one with somewhat loose poo. Is this one out of the question for us then? And how disgusting it is to clean the unit if/when it gets clogged? I have read some really bad reviews on Amazon and have been put off a little…Many thanks for any input !!

    • Lorena Ávila says:

      Hello Eva, cleaning the CatGenie is not that hard but certainly is not a breeze either. You can see a video how to clean the unit here. Personally, I would use the Litter Robot for your cats, but that’s just my opinion. Thanks for visiting my website!

    • sheri says:

      We have a cat genie. If your cats poo is even a little bit soft it is a disaster. It doesn’t get scooped out but rather smashed in to the scooper and remains for the rest of the cycle. The cycle ends with blowing it dry….. so basically that means the stench of the poop still stuck on the arm gets blown all over your house. Gross! Also… a large portion of the granules get flushed down the toilet. I haven’t researched those exactly… but I can’t imagine that it is good for your plumbing. The granules seem to be plastic. Maybe they biodegrade? Idk.. not my fav. We are looking in to other systems.

      • Lorena Ávila says:

        Hi Sheri, the granules of the CatGenie are biodegradable and yes, the unit works better with firm feces. You might want to check the Litter Robot if you need an alternative option. Thanks for sharing!

  5. Missy Squire says:

    I was looking up info on what my best oppositions are litter boxes. Thanks for your review, I currently own a Catgenie and hate it the smell when it cleans itself is absolutely horrible. The smell seeps out through the entire house even though it’s in my laundry room.And yes we keep it clean. I don’t recommend buying this also because of the cleaning supplies for it ridiculously priced and it’s not suitable for multi cat home. Since the cleaning cycle takes 40minutes. I will be looking into your advice on the robot.

  6. Ness says:

    Quick question – I see you have the Litter Robot III (I read your link re: technical reasons) – can you tell me if the pros truly outweigh the cons between it and the II Bubble? I only have one cat (4 months old) and don’t plan on having multiples. We currently have the Petsafe Simply Clean (all that was available at Petsmart when we adopted him from the shelter) and he has already figured out how to knock off the belt cover and remove the plastic bag (kitties love plastic bags for play time!!) from the bucket without removing the bucket, so I’m needing something a little more tamper proof. Looking at the Litter Robot’s website comparison, I don’t really need the additional features on the III, so I’m wondering what the benefits truly are? Can you offer anymore insight? Or should I just go ahead and plunk down the extra $50 on the III? Thank you for your advice! This review was amazing!!!!!

    • Lorena Ávila says:

      Hell Ness, both Litter Robot Bubble and Open Air are good devices. IMO the most important difference to choose the Open Air over the Bubble is the odor control. The drawer keeps the smell much better contained than the Bubble.

      Another big difference is that with the Open Air the possibility of blockage of the globe is close to zero, not the same with Bubble if you forget to empty the waste drawer after several days the globe doesn’t rotate and sometimes the outside of the globe gets dirty.

      Also, the Open Air features a shield inside the Globe that contains the clumps when they fall into the waste drawer. This avoids the upper inside of the globe to get in contact with the clumps.

      Additionally, the entry of the Open Air is much wider and bigger than the Bubble, this makes cats feel much better when going inside.

      Finally and a very important difference is the fact that the Open Air doesn’t need the cat to step on the step to activate the weight sensor. With the Classic and Bubble if your cat jumps into the unit the weight sensor won’t activate and the globe won’t rotate. That’s why the Bubble needs the ramp to the step as accessory.

      Honestly, both units will work for your cat, but I highly recommend you to get the Open Air because it addressed the issues that the Bubble and Classic have. I couldn’t suggest you otherwise since the Open Air has changed my life as a cat owner. Hope that helps!

  7. Kristina says:

    Hello! I have a couple of questions regarding the Litter Robot III. I have 2 cats, one is super picky about the amount of litter the other is a digger. I also have urinary problems with the boy (who likes a lot of litter). If the litter box isn’t clean, he will use the house. Mostly carpet. I’m so ashamed I can’t get it under control. I have a very busy schedule of full time class and work, and I’m not always able to clean it every day. No one else in the house will. I know with the cleanliness, it won’t be an issue, but I read the review. Since you can only use so much, could they both be satisfied? It looked full in the review, but will it be deep enough for my girl to not get her paw stuck? I want to know before I totally invest in a Litter Robot.

      Hi Kristina, I will start saying that almost 99% of cats take to the Litter Robot without problems. I think the issue you are having now with your 2 cats is the fact that the litter box is not always clean and this creates behavioral problems when cats need to share the same litter box. My cat Sophie uses the Litter Robot without problem, as the bottom is rounded most of the litter area is deep enough for a cat to dig. In the review I mentioned 13 cups but you can put more than that. I’ve been adding more litter lately just to check the limit point and it’s between 14 and 15 cups which is plenty of litter.

    i have 5 inside cats and I am a fanatic when it comes to keeping the boxes clean. My dilema, i have to be away for 5 days and was looking at getting an automatic litterbox. My oldest daughter will be coming in twice a day to check on my cats and litter boxes and feeding and etc. Any suggestions on which box to purchase? I was thinking of purchasing the scoop free ultra self cleaning box. Any reviews on that one?

    • Lorena Ávila says:

      Hi Donna, I personally use the Litter Robot Open Air because is 100% reliable. With the Litter Robot your daughter won’t need to scoop the litter box but only to remove the bagged waste by opening the waste drawer at the bottom of the unit. My suggestion is getting the Litter Robot Open Air and placing a regular litter box as complement for your 5 cats.

      I don’t recommend the ScoopFree for 5 cats, the litter area is not that large to handle the waste of 5 cat. You can check a review of the ScoopFree here.

    You missed the Cat-illac cat toilet system. Never need to change cat litter or pads. There is no dust, no smell, no mess and you stop filling our landfill sites with used litter – very environmentally friendly!

      Hello Perry, the Cat-illac doesn’t belong the self scooping systems. However, I will make a review soon and post it on the litter boxes category. Thanks for your comment!
