Litter Robot 3 – Full Review 2022

Do you loathe the moment when it comes time to scoop up that clumped up kitty litter and your cat’s waste?

I used to hate it until I found the Litter Robot years ago. I have used both previous versions – the Litter Robot I and II, but I must say that I and my three Persian cats are the happiest with the latest Litter Robot III – Open Air!

Litter Robot

I can honestly say that this is absolutely the greatest automatic, self-cleaning litter box available on the market today! This comes as no surprise given the fact that the producer has been making and perfecting it for over 15 years and has been taking into consideration all of the positive and negative feedback and suggestions from its customers.

It is absolutely fabulous and will help limit the scooping and the contact you have with cat’s waste, which is not only a nasty task but in some cases may be dangerous to your health, especially if you are expecting a child, because of the risk of a toxoplasmosis infection which is known to cause harm to unborn children.

With this amazing robotized self-cleaning box, you will forget about the smell, the scooping, and the whole messy operation of cleaning out the litter box of your beloved pets.

An introduction to the Litter Robot III Open Air

This is an almost entirely automatic clever litter box that will eliminate the need for scooping up waste and clumped up litter and will minimize the need for cleaning out the unit.

Its ingenious design also will help remove the nasty odor that traditional litter boxes emit and is going to save you tons of money for kitty litter in the long run, as it uses up about 30 to 50 percent less cat litter.

It is a reliable, modernistic-looking device that once you install it, will make you forget about scooping up the waste several times a day. In fact, you will feel perfectly comfortable leaving your cat or cats alone at home for several days without worrying about the smell and mess you are going to find when you return. Also, as all cat lovers know, cats like clean toilet spaces, so your fur babies will feel comfortable all the time when you are not there to tend to their needs and to ensure their hygiene.

This genius device will automatically separate the cat’s waste and the soiled litter from the clean one and store it in a waste receptacle so that the litter is always clean and so that the smell is no longer a problem in your household.

It also helps reduce the risk of nasty bacteria growing in the litter box and thus prevents your cats and you and your family from getting sick.

Overall, you will find that you will do much less cleaning and more cat petting and playing once you start using the Litter Robot III!

How does the Open Air work?


The dome-shaped litter box is fitted with a smart weight sensor that identifies when a cat weighing from 5 to 20 lbs. enters the box and when it leaves it.

Then depending on the settings, you have chosen for the cleaning timer, the rotating mechanism switches on and sifts the clumped up litter and the waste from the clean one, and dumps it into a receptacle drawer, which you can line with a garbage bag for easy emptying.

You can choose between 3, 7, or 15 minutes after the cat has done its business for the cleaning process to start. It does take some time before the litter gets clumpy after a cat urinates, so depending on the type of kitty litter you use, you can adjust the timer accordingly.

The convenient waste drawer is fitted with a carbon filter which helps eliminate the odor from the disposal receptacle.

After the cleaning process is done, the rotating globe rotates back to its original position and is ready for use by your cats once again.

The good news for the cat parents is that you won’t need to buy any special branded cat litter or bags, you can use the litter of your choice and ordinary garbage or shopping bags.

The design of the latest version of the Litter Robot features a spacious litter area, dome and a large enough entrance which is comfortable to use and will not intimidate larger or shyer cats.

You will be alerted when it is time to throw out the garbage bag from the tray when the blue indicator light switches on and a buzzing sound is emitted. All you have to do is to pull out the waste drawer, remove and dispose of the bag and replace it with a new one. Pop it back in – and voila! This is all the contact you will be having with your cat’s waste!

You can even lock the control panel to keep it safe from curious kids and kitties which as we all know love fumbling and playing with buttons and dials.

The rotating mechanism does make a slight noise, but thankfully the manufacturers of the Litter Robot III have added an 8-hour sleep mode option, so you can switch it on if you are a light sleeper. It does provide the option for turning the cleaning mechanism on manually as well.

The useful night light will illuminate the litter box when it is dark, which is quite comforting for older or nervous cats.

If you are worried about power cuts while you are gone, you can purchase a battery backup unit for the Litter Robot III which will provide up to 48 hours of operation for two cats, and more for one.

The unit is designed to waste very little clean litter, so you will find yourself buying much less litter than you used to once your cats start using the Litter Robot III Open Air.

With over 125,000 satisfied customers, and after 15 years of experience in the field of self-cleaning litter boxes, the producer is positive that the Litter Robot III will be the last litter box you will ever want to own, and that you will never need to scoop litter waste again!

Even if your cat or you are not happy with the purchase, you have a whole 90 days to reconsider and return it thanks to the money-back guarantee provided by the manufacturer.

How do you set up the Litter-Robot 3

Since it now comes preassembled, you actually only need to put the head on the base, add clumping clay litter of your choice, line the waste tray with a garbage bag, plug it in a nearby power socket, and you are done. You can adjust the timer for the cleaning cycle as you choose among the options of 3, 7, or 15 minutes after the cat has left the litter box.

What type of clumping clay litter do you use with the Litter Robot III

You can use whichever brand you prefer, and the greatest news is that this self-cleaning litter box also functions properly with Little Pearls and litter crystals, as well as with the various brands of clumping clay available on the market. So, you can use whichever type you want and yet feel secure that the unit will function properly.

What kind of maintenance does the Litter Robot III need?

Although the entire cat litter cleaning process is automatized, you will still need to replace the bags from the waste receptacle tray. An indicator light will switch on and a beeping sound will notify you when this needs to be done. Don’t worry if you are not home at that right moment. The Litter-Robot III has a sensor which will stop the cleaning cycles if the waste tray is full, in order to prevent a nasty mess from it getting overfilled.

Also, yes, you will still need to periodically clean the inside of the dome and the waste tray, but you can do that with a disinfectant spray and a damp cloth and wipe the inside and outside to keep things sanitized healthy at home.
