What Is Litter-Robot 4? How Does It Work?
The Litter-Robot 4 is the latest model in Whisker’s Litter-Robot line. It officially launched on May 10, 2022, and has been a hit with many satisfied customers. The design of the new Litter-Robot 4 shows that the makers were attentive to user feedback and made great lengths to make significant improvements from the Litter-Robot 3. Litter-Robot 4 is innovative and comes with features that the average cat owner will actually find helpful and useful.
All Litter-Robot models have convenient self-cleaning features and can detect full waste bins and when litter has to be replenished. Some of the most noteworthy updates with Litter-Robot 4 are the Wi-Fi compatibility and the less intimidating entryway for easy access. Litter-Robot 4 is also much quieter and less likely to disrupt or frighten timid cats. It also has upgraded safety features with advanced motion and weight sensors to prevent your cat from getting caught in cleaning cycles.
Litter-Robot 4 is a considerable option for multi-cat homes because it can accommodate up to four cats. It can also be a great tool for cat owners with cats that have digestive or urinary issues because it can track litterbox habits and fluctuations in cats’ weight.
Purchasing a Litter-Robot 4 is a bit of an investment, so it’s important to consider some factors that can make it incompatible with your own cat. As with previous Litter-Robot models, Litter-Robot 4 only works with clumping litter. While it doesn’t have a weight limit, cats do need to be at least 3 pounds for the Litter-Robot 4 to detect them. So, if you have a tiny kitten, you’ll have to wait for it to grow before it can use it. Also, the globe can fit most domestic cat breeds, but longer cats, like extra large Maine Coons and Bengals, may not fit inside.
Where To Get Litter-Robot 4
Litter-Robot 4 is currently available for purchase online through the Litter-Robot website. While previous Litter-Robot models may be found through Amazon, the latest model isn’t officially available for purchase elsewhere. When shopping for Litter-Robot 4, you can choose between a model with a step at the base or a model with a handle for the waste bin. It also comes with a free 1-year warranty, but you can purchase a 3-year warranty for an additional cost.

What to Expect from Litter-Robot 4
After you purchase your Litter-Robot 4, it’s important to keep track of shipping because it’ll come in a very large box. There’s no option for the product to arrive in an unmarked box, so it’s important to retrieve it as soon as it’s delivered if you don’t have a private doorstep.
Each box comes with a helpful Quick Start Guide to help you set up an account with the Whisker App and pair your Litter-Robot 4 to your Wi-Fi and mobile device. When setting up your Litter-Robot 4, make sure to place it on a level surface and away from walls.
Whisker provides instructions on helping your cat transition to using Litter-Robot 4 successfully. Once your cat gets used to it, you can enjoy its many benefits. Litter-Robot 4 is designed to eliminate scooping and make cleanup easy. There’s some routine cleanup and maintenance that you’ll have to do to keep it in good condition, but it’s easy and manageable.

Enhanced Safety Features
Litter-Robot 4 has enhanced safety features to prevent any complications or injuries. The inner compartment has multiple sensors that track motion and weight. The entrance is equipped with Curtain Sensors, which detect when a cat goes in and out of the litterbox. These sensors ensure that the litterbox stops rotating if a cat enters during a cleaning cycle. The cleaning cycle will resume 15 seconds after the cat leaves.
Weight Sensors are located at the base. These sensors also help prevent clean cycles from resuming if a cat steps inside. Litter-Robot 4 also has MultiCat technology, which can recognize up to four different cats. The Weight Sensors work with MultiCat to track fluctuations in your cat’s weight.
Additional factors that Litter-Robot 4 can detect are motions in the waste drawer, a full waste drawer, and litter levels.
Thoughtful Details
Litter-Robot 4 was truly designed with the cat owner in mind. Along with state-of-the-art safety features, you’ll discover many other convenient and helpful features. First, Litter-Robot’s design makes cleanup simple and easy. You can easily remove the bonnet and wipe it down. The waste drawer can hold plastic bag liners, and the drawer’s design prevents any waste from landing outside the liner.
The globe has a compartment for a carbon filter that dramatically reduces odors. If you need extra odor control, you can install additional OdorTrap Packs in the carbon filter compartment. Litter-Robot 4 comes with a detachable guard that you can install at the base. While the globe’s base is fairly deep, the guard acts as an extra shield that prevents litter from spilling out.
Litter-Robot 4 is also a considerable option for senior cats. While most cats have excellent night vision, some older cats may need extra help entering and exiting the Litter-Robot 4’s globe at night. The sensors in the globe enable a night light to automatically turn on when a cat steps inside and turn off after use.
You have the option of purchasing a Litter-Robot 4 with a step that can help older cats get inside the globe. The step also has ridges to catch loose litter and reduce tracking. If your cat requires additional help, a ramp compatible with the Litter-Robot 4 will be available later in the year.
Whisker App
Litter-Robot 4 has impressive technological capabilities. The Whisker App has proven to be an immensely helpful feature and has thousands of positive reviews on both iOS and Android.
After installing the Whisker App, you can link multiple Litter-Robots to your account and track their activity. The Whisker App provides useful information, like litter levels and a full waste basket, and can send you notifications whenever there’s an update that requires your attention.
The Whisker App also tracks your cat’s weight and litterbox habits. After some time, it’ll compile the data gathered from Litter-Robot 4 to chart a cleaning cycle that can help you better anticipate when you have to refill the globe with fresh litter.
The app also enables you to control your Litter-Robot 4 remotely. You can adjust the wait time and sleep mode schedules and activate the night light. The Whisker App also pairs with Whisker’s Feeder-Robot, so you can easily track your cat’s health and catch any concerns, particularly regarding your cat’s digestive health.
Only Works With Clumping Cat Litter
As with all other Litter-Robot models, Litter-Robot 4 isn’t compatible with non-clumping litter. The globe has a grate that catches clumps of cat waste and separates them from clean cat litter. We can see non-clumping cat litter getting stuck on the walls of the globe and jamming the cleaning system. So, if you’re interested in using the Litter-Robot 4, make sure that your cat is used to clumping cat litter first.
Is Litter-Robot 4 a Good Value?
People may be deterred from Litter-Robot 4 because it’s more expensive than many competing self-cleaning litterboxes. However, we consider Litter-Robot 4 to be a good value because of its high-quality build and design. Its attention to safety is unbeatable, and it has features that are both impressive and useful. So, you won’t be left with a fancy litterbox with superfluous features.
FAQ: Litter-Robot 4
Does Litter-Robot 4 Require Special Garbage Bags?
While you can purchase liners that fit Litter-Robot waste bins, you can use any plastic liner. Litter-Robot has no mandatory, exclusive accessories and can function fine without additional accessories.
How Many Cats Can Use One Litter-Robot 4?
One Litter-Robot 4 can accommodate four cats. In some cases, you may be able to have more cats use one, especially if the cats are small and don’t use up litter quickly. However, remember that the MultiCat technology can currently keep track of a maximum of four cats.
Does Litter-Robot 4 Help With Cats That Spray Very High?
Yes, Litter-Robot 4 helps cats that tend to spray very high. When the globe initiates a cleaning cycle, it’ll rotate cat litter on all the surfaces, so dry litter will catch onto wet spots. The globe has a flexible lining on the base, which will hang once it reaches the top. This will cause clumps to fall onto the grate and eventually land in the waste bin.
Our Experience With Litter-Robot 4
We tested out Litter-Robot 4 with two cats. One cat is a large male orange Tabby and is a senior cat that’s starting to experience some mobility issues. The other is a small female Tabby who tends to be shyer and timider around new things.
Both our cats were curious about Litter-Robot 4 when it first arrived. The orange Tabby acclimated to it right away and was able to use the entryway step to get in and out of the globe with ease. It took our shyer cat a little more convincing, but we believe the quiet design of Litter-Robot 4 helped immensely with her getting used to it. The change cycles are barely audible and definitely made Litter-Robot 4 less intimidating for our cats.
The flexible liner inside the globe effectively caught high sprays, and it was impressive to see the litter coat wet spots and land on the grate while the globe rotated during a cleaning cycle. Cleanup was also quick and simple. All we had to do was replace the liner once we got a full waste bin notification on the Whisker app. The bonnet covering the globe is also easily removable, and it just needs a quick wipe-down occasionally.
We didn’t have any issues with high sprays. However, we can see some cat owners having to clean the interior of the globe more frequently if they have a cat that consistently urinates on the walls rather than directly onto the cat litter.
Overall, we had a positive experience with Litter-Robot 4. Once you complete setting it up, it’s low-maintenance and it really did eliminate scooping for us. The Whisker App has a very user-friendly interface, and it’ll be interesting to see how it tracks litterbox habits as it gathers more data.
In Conclusion
If you’re looking for a helpful and reliable self-cleaning litterbox, Litter-Robot 4 is a trustworthy option. While it may have a premium price, you definitely get your money’s worth with all its convenient and helpful features. We can see elderly cat owners benefiting from it because it simplifies and eliminates a lot of work that goes into maintaining a clean litter box. Cats with digestive and urinary issues may also benefit significantly because it helps track important health data.
Fortunately, Litter-Robot 4 comes with a 90-day trial, so you can always test it out for yourself. Whisker also produces compatible accessories to make the switch to Litter-Robot 4 a seamless transition. So, all kinds of cat owners can enjoy the benefits of this useful self-cleaning litterbox.
