Litter robot 4 review

Cat owners always focus on the positives of owning a cat – from cuddles to cute pictures and funny videos. But we rarely think about the practicalities, whether it’s feeding them or dealing with where they go to the bathroom.

If yours is an inside cat, there’s no doubt that you need a litter box. Sadly, they’re not exactly glamorous; they’re often ugly, smelly, and messy. And on top of that, you probably hate scooping out the mess your cat leaves behind. Fortunately, Litter-Robot 4 addresses all of that.

Litter-Robot 4 cleans up your cat’s mess automatically, sweeping any solids or clumped litter into a waste drawer, keeping it out of sight, and eliminating odors. If you ever get frustrated by litter trays, a Litter-Robot will make owning a cat a joy again.

litter robot reviews

If you scour the internet looking for the best automatic litter boxes around, you’re sure to see countless positive Litter-Robot reviews. This is hardly surprising – with twenty years of experience and customer feedback, they’ve been able to produce the Litter-Robot 4, a device that’s treasured by over 750,000 cat owners throughout the world.

Litter-Robot 4 is a well-designed device that’s comfortable and safe for your cat, as well as being quiet and convenient for you.

How Does Litter-Robot 4 Work?

The Litter-Robot 4 has three motion sensors by the litter bed’s entry as well as a weight sensor, all of which can detect when your cat enters and leaves. As soon as your cat has done its business and exits, the motion and weight sensors will recognize this and activate the cleaning cycle.

While cleaning, the globe rotates around the litter bed, sifting dirty litter and leaving only clean litter in its place. What’s more, it does so almost silently, ensuring it doesn’t disturb you or your cat.

As the globe rotates, the dirty litter is swept away and collected into a waste compartment at the base of the unit. After a few days, you’ll receive a notification on your phone as the app tells you to empty the waste bin drawer.

Automatic Cat Litter Box

There’s no denying the Litter-Robot’s popularity. It’s at the top of every cat owner’s wish list thanks to its wide range of features and the huge convenience it offers. While there are several alternatives out there, the Litter-Robot still stands head and shoulders above the rest.

Features, Installation, and Setup

On the surface, the Litter-Robot 4 might seem like just another litter box. But it’s only when you delve into all the features available that you realize quite how impressive it is.

Despite the huge range of features packed into it, it’s still a simple device to set up. Like many others, I was relieved to discover it required no complex installation like some other litter boxes and could be set up in minutes.


litter robot size and dimensions

Although cats don’t vary in size as much as dogs, it can sometimes come as a surprise how big the size difference between two cats can be. For example, my friend’s old cat was shockingly large – especially compared to my skinny kitty!

Fortunately for pet parents, the brainiacs behind Litter-Robot are well aware of this. That’s why the latest model has a rounder entryway than previous models, measuring 15.75” in diameter. This makes it much more suitable for a wider range of cats.

However, it’s not the smallest litter box out there. If you’re looking for one that’s small and easy to tuck away, this might not be for you. It comes in at 29.5” tall, 22” wide, and 27” deep. But despite its size, it still boasts a sleek design that can fit into houses even as small as mine.


design of litter robot 4

In terms of appearance and aesthetics, the Litter-Robot 4 has a modern, minimalist design that I feel works in most home décor styles. While there’s only a choice between black and white, they both work really well and are sure to fit into your house.

The Litter-Robot’s design isn’t all fashion over function, though. It includes a step that helps older cats climb into the litter bed and reduces litter tracking.

Noise and Odor Control

No one likes the loud, grating noise of machinery while they’re trying to sleep or get on with their day. Fortunately, Litter-Robot 4 includes QuietSift™, a patented technology that cleans more silently than any other automatic litter tray. That means it can clean your cat’s mess without disrupting your cat’s nap or you watching Netflix.

The only thing worse than a loud noise is a bad smell – but odor control is something that Litter-Robots excels in. All your cat’s mess is swept into a waste drawer that’s tightly sealed to eliminate odors.

And on top of that, it even comes with a carbon filter and an OdorTrap bag specifically made to control odors. I’ve barely heard a sound and haven’t caught a whiff of cat waste yet – so it’s certainly doing something right!

App Features

The Litter-Robot’s main appeal is how little maintenance it needs – but the app that it connects to makes this even easier. By connecting the Litter-Robot to your Whisker app, you can get easy access to various features.

Real-time tracking allows you to check both the litter and waste drawer levels at a simple glance. When the waste drawer needs emptying, or the litter needs refilling, a notification will light up on your phone.

Health monitoring is also a huge advantage of the Litter-Robot. Although the SmartScale™ sensor at the bottom is mainly for your cat’s safety, it also measures their weight and detects how frequently they use the box.

Just check the app, and you can see if there’s any change in weight or toilet behavior that might indicate a health problem.

Litter-Robot 4 Price

Since the Litter-Robot 4 came out, its previous models have become cheaper. So if the price is an issue for you, it might be worth looking into something like the Litter-Robot 3. However, going with any of the previous models means you will inevitably miss out on crucial features that make the Litter-Robot so special.

The Litter-Robot 4 is currently available for $699. This might seem expensive at first glance, but since it’s a state-of-the-art device, you’ll quickly find that it warrants the premium price tag and is worth every cent.

Litter-Robot 4 vs. Litter-Robot 3

There’s no doubt that Litter-Robot 4 is a huge improvement to Litter-Robot 3, with various upgrades and added features. From the quieter cleaning cycle and improved odor control to the larger waste compartment and app connection, there are plenty of features that make Litter-Robot 4 worth your while.

But although Litter-Robot 4 is the newer one, older model models are still available, so it’s fair to consider the merits of Litter-Robot 3 vs 4.

Litter-Robot 3 might be a cheaper option, but it’s still an excellent automatic litter box that makes owning a cat much easier and more pleasant. It might not have all the features of its successor, but if you’re on a budget, it’s an excellent option to consider.

What is the Self-Cleaning Litter-Robot

It’s not difficult to find a cat litter tray. After all, there are lots out there. But getting hold of a self-cleaning litter box makes everything so much simpler.

There is a range of different types of self-cleaning litter boxes. Some rotate like the Litter-Robot, others rake the dirty litter away, and there are even a few that connect to the plumbing to flush the waste away immediately.

While Litter-Robot still ends up on top compared to the other self-cleaning options, there are still litter boxes with a range of budgets, sizes, and features that might suit you and your cat more.

How Well the Self-Cleaning Litter-Robot Controls Odors

Some people might prefer a litter tray that can get rid of their cat’s waste immediately. For example, litter trays that connect to plumbing and flush away waste leave almost no lingering odors whatsoever. However, most self-cleaning litter boxes sweep your cat’s mess into a waste compartment which you empty later when full.

Litter-Robot 4 is one of the best at controlling odors. It combines OdorTrap bags, carbon filters, and a sealed waste drawer to eliminate all smells entirely. This leaves your home smelling clean and fresh at all times without the vile stench of a traditional litter box. 

Does the Litter-Robot Scatter?

One of the dangers of automatic litter trays is litter dust being scattered all over the place when it kicks into its cleaning cycle. To address this issue, Litter-Robot 4 includes a sifting screen to stop litter dust from floating throughout the air, resulting in less dust to clean from the room and the box itself. 

Which Kind of Litter Works Best in a Litter-Robot 4?

Although Litter-Robots are great in separating clean litter from dirty clumps, you can’t just use any old litter you find in the supermarket. There’s a range of litter to choose from, like clay, natural, and silica gel. But it’s important to select the best litter for Litter-Robots.

Clumping clay litter is best for Litter-Robot. As it rotates, it needs to be able to easily separate clean litter from solid clumps. Other types, like silica gel crystals, can also work, but only if they’re small enough; even then, you should make sure it clumps well.

No matter what the litter you choose is made from, you should always make sure it clumps enough to be sifted away by the Litter-Robot. Absorption and clumping are key to avoiding sticky litter and poop that refuses to be swept into the waste box.

Things to Consider Before Buying Litter-Robot 4

There are a few questions you should ask yourself before jumping into getting a Litter-Robot.

  • Will your cat use it? After all, it’s an expensive device. If your cat’s very picky about litter trays, you don’t want to risk them not using it and ending up wasting your money.
  • Do you have space? With all its features, it’s no surprise that the Litter-Robot is quite a large machine. Although it’s not huge, it’s bigger than some others, so you need to find a big enough space to fit it and make sure it’s close enough to plug into the mains.
  • Can you afford it? If the Litter-Robot 4 isn’t in your budget, then it’s not worth breaking the bank. Yes, it’s an impressive bit of kit and makes owning a cat much easier, but you can still opt for the cheaper Litter-Robot 3 if you need it.

Care and Maintenance of Litter Box

The best thing about Litter-Robot is that daily scooping is a thing of the past. Instead, you just empty the waste compartment every few days when you get a notification from the app.

However, it’s recommended you give the device itself a deep clean every three months or so. Simply empty the box of litter and unplug it from the main before pressing the buttons to lift up the bonnet, remove the globe, and take away the carbon filter.

With the components taken apart, just clean them with a spray, wipes, or simply water and mild soap. No electrical components are at risk of being damaged, so you can even soak the components in water if necessary. Once everything is dry, simply reassemble them. If you have any issues, all instructions can be found in the manual. 

Is Litter-Robot 4 Worth It?

Whether or not the Litter-Robot is worth it is totally down to you. If it’s in your budget, then why not? After all, not needing to scoop out waste makes owning a cat easier and much more pleasant.

But it’s more than just about convenience. With the sensors, you can keep tabs on your cat if you’re worried about them, giving you the ability to track their weight and bathroom habits.

It might even help if your cat is a bit of a princess and demands the best. If they refuse to use a clean litter tray, if it isn’t always spotless, then the Litter-Robot can guarantee them a clean litter bed every time.

Litter-Robot 4 can completely change the experience of owning a cat. But since it’s such a pricey product, there are several questions cat owners have before purchasing one.

Will the Cats Be Able to Push the Button on the Settings of the Litter-Robot?

It’s very unlikely that your cat will be able to push the buttons. Since they’re placed towards the top and on the side, there’s no chance that their paws will come into contact with them at any time. Even if they jump on top of the Litter-Robot, the buttons are still out of the way.

How to Clean a Litter-Robot 4?

Cleaning your Litter-Robot is simple and should be done every three months or so. All directions can be found in the manual that comes with the device. Simply empty it of litter, take the components apart, and wipe them down with spray, wipes, or soapy water.

No electric parts are exposed, so feel free to dunk them in water for a major cleaning if needed.

Do Self-Cleaning Litter Boxes Work?

Yes, self-cleaning litter boxes do work, but they’re not all as good as each other. Some get jammed as clumped litter gets stuck in their mechanisms. Fortunately, as it’s one of the best automatic litter boxes out there, this is unlikely to happen with the reliable Litter-Robot 4.

How Often Should I Scoop a Litter Box?

You should scoop a traditional litter box at least once a day – if not two to three times to ensure it’s hygienic and make sure your cat continues to use it. However, since the Litter-Robot does this automatically, the best thing about it is you never need to scoop again!

What You Need to Know About the Litter-Robot App?

You can do nearly everything via the Litter-Robot app. In fact, you don’t even have to use the buttons on the device since everything can be done on the app, such as putting it into standby or sleep mode.

The app also lets you know when to empty the waste drawer or refill your cat’s litter box, as well as shows you any changes to your cat’s weight or bathroom habits. 


If you’ve done any research into automatic litter boxes, then you’ll know that the Litter-Robot 4 is up there with the best. It has the convenience of all other self-cleaning litter boxes but with added features to put it on top, and certainly worth the money.

Whether it’s the quiet cleaning cycle, supreme odor control, large waste drawer, or easy-to-use app, there’s something there for everyone to appreciate. Litter-Robot 4 is thoroughly recommended for any cat owner who wants less time cleaning and more time cuddling with their cat.
