When you welcome a cat into your home, an important consideration is choosing the best litter box for your cat. While there are many options to choose from, one of the easiest litter boxes to maintain is an automatic litter box.
Most cat parents will agree that scooping cat litter can be unpleasant and time-consuming. There are many advantages to an automatic cat litter box, especially when compared to a traditional scoop litter box. Let’s explore these benefits and decide what is the best automatic litter box for you!
How does an automatic cat litter box work?
When you have a traditional scoop litter box, it is up to you to check the status of the litter, clean the box, and maintain it all on your own. However, when your cat has an automatic litter box, it is no longer your responsibility to scoop litter.
An automatic litter box can detect when your cat has used the bathroom. It will then scoop, or cycle, the waste into a receptacle, which is typically stored underneath the litter box itself. Once your cat uses it, the automatic litter box will sift the soiled litter from the clean litter.
All waste will be deposited into the waste drawer underneath the litter box. Depending on the type of automatic litter box you choose, you may even receive notifications when the waste drawer is full and needs to be emptied. This process is a major time saver!
What makes a good automatic litter box?
So, what exactly makes for a good automatic cat litter box? We suggest looking for the following main features.
Rotation sifting instead of a raking system

Prefer self-cleaning litter boxes that feature a rotating motion to dispose of the waste over rake mechanisms. “Raking” automatic litter boxes often jam or clog and nobody wants to have to scrub poop out from the rake when it gets stuck there. Yuck. Opt for a sifting rotational system instead.
Smart insights
You may not consider litter boxes as state-of-the-art technology. However, most automatic litter boxes feature advanced technology that is up-to-date, user-friendly, and convenient. WiFi connectivity is a feature that most automatic cat litter boxes come with because it allows you to connect your litter box to an app and receive push notifications when it’s time to empty the waste drawer.
Some automatic litter boxes like Litter-Robot 4, will notify you via the app on your phone when it needs to be emptied. You can even receive smart insights into your cat's weight and litter box usage, plus view litter levels in real time, all in the palm of your hands.
Multi-cat recognition is also a must for any multi-cat household. A good self-cleaning litter box should have this feature so you can better track each cat's habits and identify odd behavior as soon as possible.
For instance, if you notice a dramatic spike in litter box usage, it might be a sign of a cat UTI that requires a quick trip to the vet—just as these pet parents did when the Whisker app started notifying them every 10 minutes. Hear their story below:
Large drawer capacity = less frequent emptying
What's the point of a self-cleaning litter box if you have to empty the waste drawer just as often as you had to scoop? Many automatic litter boxes only feature a small waste compartment that won't hold more than a few days' worth of use, even less if you have multiple cats.
Look for an automatic litter box with a large waste compartment like Litter-Robot 5. Litter-Robot 5 uses a smart waste distribution technology to optimize how much waste the drawer can fit. Thanks to that improvement, you can go up to 10 days before having to empty the waste drawer with a single cat.
Product warranty
As cat parents, we know that litter boxes are used every day. Because of this frequency of use, it is important to make sure your automatic cat litter box will stand the test of time.
Not all automatic litter boxes come with a product warranty or guarantee but it can offer consumers peace of mind on their investment as they’ll know that they can rely on good customer service if they have issues with their litter box.
Additionally, a self-cleaning litter box that is easy to repair will be much better for the environment (no products will end up in landfills) and, of course, better for your wallet!
Odor control - Look for air filtering features

Most cat parents are acclimated to smelly litter boxes that are out in the open. This can be quite embarrassing when guests come over. A main benefit of a self-cleaning litter box is its ability to quickly sift, remove, and store waste. They also have odor control features in place, which help reduce odors quickly and consistently, unlike traditional litter boxes.
However, many self-cleaning litter boxes only store the cat waste in a small enclosed compartment that doesn't fully lock odors away. Look for an automatic litter box that has a tightly sealed waste drawer like Litter-Robot 4.
The best self-cleaning litter box for odor control should also feature carbon filters or a way to add a litter box odor eliminator. Even better if it comes in a single package in a bundle with everything for litter box cleaning.
Space fit for large cat breeds
Large cat breeds, don’t fit comfortably in regular litter boxes and typically need litter box solution tailored to large cats. In fact, studies show that a larger litter box receives 55% more usage than a standard-sized litter box.
While space might be a constraint, especially in a small apartment or house, aim for a litter box that has a similar footprint as a standard litter box but that has a larger opening.
Quiet operation

Your automatic litter box should not wake you up at night. That's just a hard requirement. But some of these machines can be pretty noisy, especially if located in or near the bedroom and your cat uses it at night. No, thank you.
Instead, look for a unit that either operates quietly or has a sleep mode and won't make a ruckus while everyone is asleep.
