Litter Robot 3 Review: What is the litter robot and what Does It Come With?


The Litter Robot 3 is a modern looking litter receptacle that replaces the common litter box found in millions of homes, considered by many to be the perfect solution and worth the money. It has a large chamber that can accommodate multiple cats, and the Litter Robot 3 automatically sifts and self cleans after each use at a time interval that you can specify. 

The waste is disposed of in a drawer underneath the chamber of the Litter Robot, and there’s an indicator light that takes the guesswork out by letting you know when it needs to be emptied.

So besides removing the waste drawer liner when it’s full, there’s nothing else you have to do.  The Litter Robot III takes care of the rest.

In addition to the Litter Robot 3 unit, which conveniently comes pre-assembled, you also get a carbon filter, waste drawer liners, power supply, Quick Start and Reference Guides, Instruction Manual, Return and Repack Instructions and other user materials.

Litter Robot offers replacement bags and replacement parts as well, and a wide range of accessories for your Litter Robot 3, including ramps, washable rugs and cabinets for your cats.

Review: How Do You Set Up The Litter Box III & How Does It Work?


One of the best parts about this machine is that it is ready to use right out of the box.  You just need to follow a few simple steps and you’re good to go.

First,  place the Litter Robot iii unit on a flat surface, preferably in the same location as your previous litter box.

Fill the globe up with litter to the indicated full line.  The company sells their own clay-based type but you can definitely use other brands as well.  You can read  more about the type of litter you should use below.

Note: Make sure you keep the litter level at the full line, as it may not function optimally with too much or too little.

Next, plug the small end of the AC/DC  adapter cord into the unit and the other end into a wall outlet.  Press the Power button.

After a brief initialization cycle, about 2 ½ minutes long, the Globe will be in the Home position with the blue LED light on.  That means that it is now ready to use.

Buttons & Functionality Reviews

Besides the power button,  you will find the cycle, empty and reset buttons on the control panel.  These allow you to set the night light, 8 hour sleep mode, wait time setting and control panel lockout.

There are also several indicator lights that tell you the current status of the Litter Robot 3.   As you’ve read, a solid blue LED light means the unit is in ready mode.  A flashing blue light means that the waste drawer is full.

The solid yellow light means the machine is either cycling or emptying and a flashing yellow light means the cycle was interrupted by the cat sensor, bonnet removal or anti-pinch safety feature. Any one of these three things will stop the it from operating.

The solid red light means that the Cat Sensor is activated, and the unit will show the solid yellow light after three, seven or fifteen minutes, depending on what you have it set to.

If you see a flashing red light that means the Cat Sensor has been activated for two or more minutes due to the fact that the cat is not exiting or the unit is overfilled.


Setting the timer & understanding the cat sensor

As far as how to set the timer, one of the most common questions we get when coming up with these reviews, it’s a very easy process.  All you have to do is just press and hold the Empty button until you get to the Wait Time Setting mode.  Then press the Reset button to change the setting to the desired time.  Press and hold the Empty button once again to save your setting, and the process is complete.

The default time is 7 minutes, but you can change it to 3 or 15, whichever you prefer.  Just note that reducing the time to 3 minutes may not be ample enough time for clumps to full form, which is why the company recommends at least the 7 minute cycle.

The Litter Robot 3 senses when your cat enters the globe and when he leaves.  The chamber then rotates and a screen separates the clumps from the clean litter, which are then deposited in a drawer below.   It’s then ready for your cat’s next visit, and only needs to be emptied when you see the indicator light.  It’s that simple.


Best Cat Litter For The Litter Robot Open Air


In order for it to function properly, you need to use a clumping type. 

 You can use litter beads and crystals as long as they are small enough that they can pass through the screen. An interesting choice lately has been a color changing litter that detects health concerns for your kitty; you can check out our review for Pretty Litter here.

Strictly absorbent, non-clumping, loose clumping, newspaper based litters and absorbent wood-based pellets will not work.

If you’re unsure of what type to use you can opt check out the most recommended one here.

We're always asking our cat community network what works best for them, and this clumping litter brand is always brought up. You can read the full review of World's Best Cat Litter for more information.

  • It can be a little noisy, but is far quieter than some competitors like the CatGenie.

Litter Robot Cleaning & Maintenance

Although the Litter Robot 3 is an automatic litter box and is very low maintenance according to our reviews & ratings, there is some necessary care to keep it in tip top shape.

Besides emptying the drawer liners periodically, you should replace the carbon filter every few months for the Litter Robot iii.  They come in packs of three and typically cost under $20.

The Litter Robot iii globe itself can be removed and cleaned with water and mild soap, or cleaned with a hose or power washer if it is very dirty.  The waste drawer can be cleaned in a similar fashion and you should rinse the carbon filter at the same time.  The base can be wiped with a damp cloth but we recommend to not use bleach as it may harm the unit.

As you can see, it’s very easy to clean and maintain it.  Keeping on top of this will ensure a long life span for the unit.

Can Kittens Use The Litter Robot?

If your cat  or kitten weighs less than five pounds the sensor on the Litter Robot III may not be able to detect when he enters and exits, and therefore the automatic cleaning cycle for the kitty poop may not be triggered.

As such for lighter cats the Litter Robot company recommends that you use the machine in semi-automatic mode. 

You should leave it unplugged or turned off, wait seven minutes or so after your cat is finished and then plug it back in.  The Litter Robot machine will then do a clean cycle and you can unplug it or switch it off again until the next time your cat uses it.

Once your cat has exceeded the five pound threshold you can then use the machine in fully automatic mode.  At that point it will be able to review & recognize when he comes and goes and initiate the subsequent sifting and cleaning process.

If your cat  or kitten weighs less than five pounds the sensor on it may not be able to detect when he enters and exits, and therefore the automatic cleaning cycle may not be triggered in the Litter Robot iii.

How Often Does The Waste Drawer Fill?

The time it takes for the drawer to fill will depend on how often your cat(s) use it. 

There are infrared emitters and sensors that detect when the waste drawer is full, at which point you will see a blue flashing LED light to alert you.

Please note that once the Drawer Fill Indicator is activated, the Litter Robot III machine will only self clean two more times and then the sensor becomes inactive.  At that point you will need to empty the waste drawer for the machine to be operational again.

According to our reviews, this is a great feature that prevents excessive buildup and avoids potential clogging that can affect performance.

Reviews: How Does The Litter Robot 3 Compare to The Previous Models?

There are several improvements on the Litter Robot 3 based on the company’s research and feedback from customers.

It has a larger chamber to accommodate multiple sizes of cats, and creates a more open air feel with its upward-facing entryway.

The previous models didn’t have the Drawer Full Indicator light, one of the most appreciated upgrades.

It also now has the automatic night light to help older cats,  the adjustable cycle timer for customization and the 8 hour sleep mode for quiet.

The plastic shield of the Litter Robot iii included on the new model helps ensure that the globe stays cleaner and your cat doesn’t come into contact with feces.

So you can definitely say the Litter Robot 3 is bigger and better than before, with a number of significant upgrades that make it even more effective.

What Is The Litter Robot 3 Connect?


The Litter Robot 3 Connect is a Wi-Fi enabled version that allows you to monitor and control one or multiple units remotely.

Using the convenient app, compatible with later versions of Android and iOS, you can check the waste drawer level, get push notifications and custom alerts, and monitor your cat’s usage.

You can also manage your settings, including adjusting the cycle time, activating the lock out feature,  turning on the night light or putting the machine in sleep mode.

It’s a great way to keep tabs on everything and ideal for multi cat households with additional Litter Robot 3 units.  You can have them all on one account and all family members can have access to it.

Other than the remote monitoring capability of the Litter Robot, both units are essentially the same as far as how they operate.

However, unlike the regular model, which is only available in bisque, the Litter Robot 3 Connect comes in beige or grey.  It cost just under $500, so it’s $50 more expensive, but offers much more functionality so you might decide it’s a better option for you.

The Litter Robot Connect 3 gets very good reviews, just like the regular version's reviews, but a few customers reported having some problems with the app, including various connection and support issues.

Rest assured that the company is aware of these concerns and they are working diligently to address the various bugs.  We’re confident they will have it resolved before long.

Does The Litter Robot Reduce Litter Odor?

stop the smell of the litter box

The Litter Robot 3 definitely reduces odors and you will notice the difference right away after the cleaning cycle.  It achieves this in two ways. 

First, it sifts away the clumps within minutes after your cat is finished, so the waste is not sitting there in the open air.

Second, the waste drawer is fully enclosed and carbon filtered, so the odor is contained and minimized.

Compare this to a traditional litter box where the clumps are sitting there for an extended period of time and exposed to the air and you can see how the Litter Robot 3 can significantly eliminate odors with it's advanced cleaning cycle.


The Litter Robot offers several recommendations when it comes to getting your cat acclimated to it and using the machine optimally.

For starters, you should place the Litter Robot 3 self cleaning litter box machine  in the same place as your previous litter box for familiarity and give your cat some time to get used to it before turning it on.  You can use catnip or a treat to make it more appealing and encourage your cat to give it a try.

It’s a very good idea to add a scoop of litter from the previous litter box as well, as your cat will recognize the scent and hopefully be more willing to approach.

If you find that your cat is not using the Litter Robot 3 machine after a few days,  you can try not cleaning the old box and see if that dissuades your cat from using it in favor of the new one.   This sometimes does the trick, as cats prefer a clean litter box.

When you reach a point where your cat is consistently using the new Litter Robot self cleaning litter box machine, you can then turn it on and let it do its magic.

As far as the unit itself, you should always place the unit on a firm, level surface.  If you place it on a deep carpet the sensitivity can be affected.

As we mentioned, you shouldn’t put anything besides clumping cat litter in the Litter Robot Globe.  You shouldn’t sit on it or place anything on it, as that might damage the Litter Robot III.

While the machine is rotating and cleaning, don’t remove the Globe or the Bonnet. 

Also, if you have removed the Globe for cleaning purposes, make sure you don’t turn the power back on before replacing it as you could injure yourself if your hair or fingers get caught.

Lastly, make sure you don’t wet or submerge the Bonnet or the base of the Litter Robot unit as that could cause damage.

Litter Robot III open air Ratings Conclusion

The new Litter Robot 3 is a welcome addition to any home, and an absolute must for those that are still using the smelly old traditional litter boxes and garbage bags.
