The Litter Low Down

The Automatic Litter-Robot III Open Air has been designed to work with various types of clumping litter, not just premium clumping clay litters. The sifting screen is suitable for clumping, scoopable clay litters, as well as alternative litters such as Litter Crystals or World’s Best Cat Litter as long as clumping. Wood and paper based clumping litters are not well suited due to size of particles and light weight for volume.

My cats (four of them) use it when it just arrived, how exciting! Spoil your cat and spoil yourself !!

Life changing

I bought a Litter Robot earlier this year after seeing it in action at a cat show. I was pretty apprehensive about spending $1000 on a litter tray but this is so much more than a litter tray! I have 5 cats, so naturally, litter trays are the bane of my existence but the Litter Robot has ensured I never have to deal with that messy litter tray situation again. I absolutely recommend it for anyone who has multiple cats. I had a few issues at first working out the right type of litter to use but the people at Cat Evolution were so wonderful about helping me figure it out. After that, it was all smooth sailing. If you hate dealing with litter trays, this easy to use Litter Robot WILL change your life.

Best present

I purchased a automatic Robot last November as soon as they arrived in New Zealand it has been the best pre Christmas present I have bought I have 2 Sphynx cats that were already trained with the Robot before I got them even my older Sphynx that had never seen or used one has taken to using it very quickly


“The Litter Robot has revolutionized our lives! We save time and money on litter changing and the cats are happier. We recently upgraded to the latest model and it is so quiet!”   Really loving it.  


We absolutely love our litter robots and so do the cats. I don’t know how we managed without them! Our litter robot is the best purchase we have made in a very long time. Perfect for indoor cats and they love it.  Very happy.

Litter-Robot III

The Sphynx kids and us are enamoured with our new A.I friend. It has taken a couple of days but all three cats are using it now. The litter robot has changed our lives! We used to be a three litter-box household, with a twice a day emptying scheduled – and it was driving us a little nuts. Throughly digging the ‘no more scooping’ lifestyle.


We are all good with the litter robot, its working great and makes our lives SO SO SO much easier!

Review of Automatic Cat Litter-Robot III Open Air

After spending a year with three new ragdoll cats and corresponding litter trays, I finally discovered the litter robot. This amazing piece of equipment has restored my sanity! Not only is it a constant source of entertainment for our rag’s, it is clean, quiet, doesn’t smell and is cost-effective with the clumping litter. It is music to my ears hearing it cycle and knowing that I am not having to scoop out the latest ‘deposit’. The service we have received has been fantastic, the litter bot arrived within a couple of days and I was updated on its journey progress while in transit. The payment system on the website is secure and post-purchase emails on transitioning tips were easy to follow and worked a treat – thank you!!

Litter Robot

The Litter Robot has proved to be a ‘sanity saver’. Four Sphynxs formerly meant four litter trays to be emptied and scrubbed and refilled both morning and night….a seemingly full time and never ending chore. With the Litter Robot I’ve uttered a final farewell to the bore of being a bathroom attendant. It is efficient, involves little real effort, is loved by my four legged friends and provides endless entertainment for the mischievous youngest who delights in the action.

Perfect house maid

We love our litter robot! It’s made things safer for our toddler as there is nothing gross to touch and it has a child lock!! We put it on the shortest timer and its emptied 3 minutes after Ivy uses it. Perfect for pregnant woman too as it’s emptied without having to touch anything and it doesn’t smell so even hubby doesn’t mind doing it! Perfect for young families!

Will my Cat Use It?

Cats are generally curious and tend to investigate new things. Those already familiar with a covered litter box may be quicker to investigate.

We recommend placing the Litter-Robot where the old litter box used to be, especially if your cat is fearful of new things. You can remove the old litter box or leave it next to the Litter-Robot for a short time. Then, take a cup of litter from the old box and put it in the globe of the Litter-Robot. The scent will be familiar, and your cat should be inclined to check it out. Once your cat ventures inside and feels the litter under his paws, he’ll know what to do! Check out Making the Switch for more tips and tricks.

Can kittens use the Litter-Robot?

It depends how much your kitten weighs. The Litter-Robot senses the weight of your cat to know when it enters and exits, which triggers the countdown timer and cleaning cycle.

Kittens and small cats that weigh less than 2.2 kilograms may not be heavy enough for the sensor to detect. Until they weigh enough, we recommend using your Litter-Robot in “semi-automatic” mode to keep your cat safe and relieve you from litter box scooping.

For “semi-automatic” mode, leave the Litter-Robot switched off or unplugged. When you see your cat has used it, wait about 7 minutes for the waste to clump, then turn it on/plug it in. The Litter-Robot will automatically perform a cleaning cycle (takes about 2 ½ minutes), then turn it off/unplug it again. Continue this supervised, semi-automatic mode until your kittens have gained sufficient weight to activate the cat sensor.

Does the Litter-Robot have a weight limit?

No, the Litter-Robot does not have a weight limit. Size and weight often have little to do with whether a cat will adopt the Litter-Robot or not.

When we describe which Litter-Robot model is best for cats of a certain size, our recommendation is based on the size of the globe (litter bed area and height of internal space) and the size of the entryway.

Our definition of a small cat is 2-5 kilograms; medium cat is 5-7 kilograms; large cat is 7-10 kilograms; and extra large cat is any cat that weighs more than 10 kilograms. Again, the Litter-Robot does not have an upper weight limit, so whether or not the Litter-Robot will be comfortable for a large or fat cat is up to the individual.  The Litter-Robot Open Air was made with larger cats in mind. It has a larger entryway and expanded litter bed area to accommodate larger cats. 

Where should I put my Litter-Robot

At first, we recommend placing your Litter-Robot near your cat’s old litter box. As soon as your cat starts using the Litter-Robot regularly, remove the old litter box. At this point, the placement is up to you. Because the Litter-Robot reduces almost all odor, prevents litter tracking, and has an 8-hour sleep setting (when it will not cycle), you can place it in virtually any room in the house without disturbance. If you decide to place it out of sight, set a reminder, so it’s not out of mind! You’ll need to change the waste drawer liner about once every 7-10 days (with one cat) and add litter as needed.

My cat won’t use it. What should I do?

Just for cases like this, we have compiled a list of tips and tricks to help your cat make the switch to the Litter-Robot. If you have tried these things and your cat still refuses to use the Litter-Robot, don’t worry; you are protected by our 90-Day Money-Back Guarantee. If you and your cat are not completely satisfied for any reason, just return your Litter-Robot within 90 days of receipt for a refund of the purchase price, less shipping.

Does the Litter-Robot require special litter?

The Litter-Robot works well with almost any clumping or scoopable litter. Litter beads and crystals that are small enough to pass through the screen will also work.

The Litter-Robot is not compatible with litters that are strictly absorbent, non-clumping, loose clumping, newspaper-based, or wood-based pellets. You’ll find these incompatible litters create a muddy mess and interfere with the sifting process.

Feline Pine is not compatible with the Litter-Robot. The large pellet size does not sift well. It builds up on the screen, causing clean pellets to spill into the waste drawer during the cleaning cycle.

We suggest Cat Evolution Premium Clumping Litter .

Will the Litter-Robot eliminate all litter box odour?

No, the Litter-Robot will not eliminate all litter box odour. However, because waste is promptly removed and contained in the base, typical litter box odour will be reduced significantly. Additionally, a large carbon filter located in the front of the waste drawer absorbs odours and moisture to discourage mould growth (a major culprit of that telltale litter box smell). The amount of odour control the Litter-Robot will provide depends on the amount of odour created—by how many cats use it, what type of litter you use, and your cats’ diets, among other things.

Of course, the more often you empty the waste drawer, the less opportunity there is for odour to escape. That said, if you empty the waste drawer and notice the Litter-Robot is still a source of unpleasant odours, we recommend changing out the bed of litter completely, deep cleaning the Litter-Robot twice per year, and replacing the carbon filter and seal strips as needed (available here). 

It is also worth noting that scented litters are generally not as effective at absorbing odors as unscented litter. Instead, we recommend an unscented, odour-trapping, natural litter like Cat Evolution Premium Clumping Litter.

How often do I need to empty the waster drawer?

It depends on how many cats use the Litter-Robot, how big they are, and your personal preference. On average, for one adult cat, it is typical to empty the waste drawer once every 7-10 days; for two adult cats, you may need to empty the waste drawer up to two times per week. Check out this infographic for more information. 

The Litter-Robot Open Air is equipped with infrared emitters and sensors that detect the level of waste in the drawer. A light on the control panel will come on to alert you when the waste drawer is full and needs to be emptied. 

I have more than one cat. Can I use one Litter-Robot for multiple cats?

Yes! Multiple cats can use the same Litter-Robot—and each one will have a clean place to go each time, thanks to the automatic cleaning cycle. More cats means more waste, so make sure to empty the waste drawer more frequently. Use this infographic to learn how many units are best for how many cats.

If one of your cats is a kitten or may not weigh 2.2 kilograms, be sure to leave the Litter-Robot switched off or unplugged. When you see your cat has used it, wait about 7 minutes for the waste to clump, then turn it on/plug it in. The Litter-Robot will automatically perform a cleaning cycle (takes about 2 ½ minutes), then turn it off/unplug it again. Continue this semi-automatic mode until your kitten has gained sufficient weight to activate the cat sensor. See Can kittens use the Litter-Robot? above for more information.

Does the Litter-Robot require special garbage bags?

No, the Litter-Robot does not require special bags or liners for the waste drawer. As long as it fits, you can use it. Customers often use 35 to 50-litre kitchen garbage bags or large plastic grocery bags. If you’re looking for an eco-friendly option, check out our custom-fit, biodegradable Waste Drawer Liners in various size packs (three come free with each Litter-Robot).

What happens if my cat tries to enter the globe while it is rotating?

The Litter-Robot will stop immediately. The cat sensor will detect your cat (by weight) and turn off the motor. It will wait 15 seconds, then attempt to resume the cleaning cycle.

If your cat or something else is still tripping the cat sensor, the Litter-Robot will not resume the cleaning cycle and a series of lights will flash indicating the problem. The Instruction Manual will help you troubleshoot common problems and our Customer Service team is here to help when you need it.

Will the globe turn while my cat is inside?

No, the globe cannot turn while your cat is inside. The cat sensor is tripped any time a cat enters or reenters the globe, resetting the timer for another 7 minutes, thereby preventing a cleaning cycle from starting while your cat is inside. See How It Works for more information. 

Are there any rakes, obtrusions, or wires inside the globe that may injure my cat?

No. The globe does not contain any mechanisms or wires that could hurt or harm your cat. The Litter-Robot was designed with your cat’s safety mind.

Are the electronics or power source dangerous to my cat?

No. The Litter-Robot operates on 15 Volts DC using a wall plug adapter similar to the adapters or chargers that you may use at home, including your cell phone charger. Unlike some other automated designs on the market, the Litter-Robot 15 Volt DC control system components are concealed inside the base of the unit (under the globe), unreachable by your pet. There are no electrical components or shock hazards inside the globe.

What happens if the globe jams?

If the globe jams, the motor will stop all rotation and the red and yellow lights on the control panel will flash. To fix, turn the Litter-Robot off, then on again. If the jam persists, call Customer Service at 1-877-250-7729.

The Instruction Manual will help you troubleshoot common problems and our Customer Service team is here to help when you need it.

Is dust a problem with the movement of the litter?

Not at all. In fact, dust is virtually eliminated. The slow rotation of the globe combined with the size of the filtering screen results in minimal agitation of the litter. We often hear from customers that this is one of their favourite things about the Litter-Robot: freedom from scooping means freedom from inhaling dirty dust!

How much power does the Litter-Robot consume?

If you’re worried about going from a human-powered litter box to an electric one, don’t be. The Litter-Robot consumes a very small amount of power. Based on the Open Air, when the motor is working to rotate the globe during a cleaning cycle, the Litter-Robot uses just 2.7 Watts of electricity. When the Litter-Robot is on standby, which is 99% of the time, it uses just 0.36 Watts of electricity.

What methods of payment do you accept?

Cat Evolution accepts bank transfers through POLI secure payment gateway, and PayPal. We do not accept checks or money orders.

Dose it take long time be in stock?

We are expecting the new stocks to be available around 1 October. They are already on their way!
