Automated, self-cleaning litter boxes promise to relieve cat owners from one of their least favorite tasks, but are they all they’re cracked up to be? Here’s our guide to self-cleaning litter boxes and our top four overall picks.

Cleanliness Matters

Cats don’t need a lot of maintenance, but one of the most important parts of cat ownership is scooping the litter box. A clean, sanitary litter box is important to keep your cat healthy. It’s also the only way to keep cat odors from taking over your house.

Felines are fastidious, and they hate using dirty boxes. Think about it. You don’t want to use a dirty, unsanitary bathroom, and neither does your precious pet. Keeping that box clean, however, is one of the least enjoyable aspects of living with a kitty. Can a self-cleaning litter robot lighten the load?

Our Hands-On Experience

We tested many self-cleaning litter boxes. With so many on the market, we decided to narrow it down by litter type. We wanted to stick with boxes that used regular litter you can buy easily. Price was also important, and all the boxes on our list offer excellent value for any budget.

Our testers found that most cats responded well to the top litter boxes we chose. Some owners reported difficulty getting older, nervous kitties to use the boxes. In those cases, it was too stressful to continue trying to get them to switch. It’s a decision only you can make for your pet.

The two reviewers who were lucky enough to try the CatGenie self-flushing “kitty toilet” were thrilled with the results. They liked that it was easy to set up and had several ways to personalize the frequency of cleaning, flushing, and washing. On the downside, it requires hooking up to your water system, and it is triple the price of the other boxes.

How To Use a Self-Cleaning Litter Box

The main thing to understand about self-cleaning boxes is they don’t do all the work for you. You still have to buy litter, clean and replace waste boxes, dispose of litter and sweep litter from the floor.

They can, however, end the task of scooping dirty litter. This is a big help, especially for owners who can’t easily scoop the box themselves.

How Does a Self-Cleaning Litter Box Work?

A self-cleaning box is a litter robot that scoops pet waste and collects it in a receptacle. An automatic litter box will begin sifting the litter and removing waste when a sensor shows that a cat is using the box. Some boxes wait for 15 or 20 minutes to make sure the cat has left the box before they start.

Other boxes require you to push a button or lever. With this type of box, you choose when to use the automatic cleaning function. This is helpful for people whose cats have difficulty adjusting to the automatic noise and motion of a self-cleaning box. You can set it in motion when your kitty is not around.

With all types of self-cleaning litter boxes, you must dispose of the waste that collects in a small bin or waste compartment.

Get Your Kitty Used To the New Box

As those of us who live with them know, getting a cat to try anything new can be difficult. If you want to encourage your feline friend to use the new litter robot, you will need patience. This process takes several steps, and skipping one will put you back at square one.

  • Place it in a private location. Cats like privacy when they use a litter box. Always place litter boxes in a private, quiet location and away from their food bowls. Kitties need to see if other animals or people are approaching their boxes, and they like having escape routes in case they need to run.
  • Let your kitties see and smell it. Before you start using it, take the box out of its packaging and let your cat examine it. Chances are he or she was already curious about what was in the package.
  • Place it near the old litter box. Let your cat continue to use the old litter box, but leave the new box next to it. Don’t turn it on or run it during this time. Let your kitty get used to having it there.
  • Run the box. Once your cat is used to having the other box around, run it once or twice a day. This will help your cat get used to the noise of the box. Don’t do this while your cat is in his box or near it.
  • Fill the new box with litter. Use your cat’s favorite litter in the new box. If you see your kitty using the new box, you’re on the way. Let your cat use the new box for a few days without running the motor. If you happen to be there when your cats are using it, praise them profusely.
  • Start the self-cleaning. After two weeks of letting your cat use the new box without running it, start running the self-clean function. Leave the old litter box in place for the first month or two. If you see your cat consistently using the self-cleaning box for a month, it’s safe to remove the old box.

Are There Any Boxes That Flush?

There is one litter box that not only self-cleans but flushes the waste. The CatGenie self-flushing cat box hooks up to your home’s existing water line. It uses self-washing granules that you don’t need to replace. We’ve included it in our product review.

Litter for a Self-Cleaning Litter Box

Most of these boxes use the same scooping litter that you can use in regular boxes. Your regular brand will work in most of the boxes.

If you’re using the CatGenie flushing box, you must use the odor-control CatGenie flushable crystals.

How Do Cats Respond to Self-Cleaning Litter Boxes?

We had mixed reports from our testers. Overall, pets who have naturally adaptable, curious personalities were more willing to give the new box a try. Older cats and those with skittish personalities were less likely to appreciate a change in their box or routine.

Based on their reports, we recommend using a self-cleaning litter box that is quiet and uses your cat’s favorite litter.

Our testers also found that most cats disliked any self-cleaning litter boxes that had covers. As with regular litter boxes, cats preferred to use uncovered, open-air boxes.

When Should You Use a Self-Cleaning Litter Box?

There are some situations where a self-cleaning litter box is essential, and others where it just makes life with your furry friends more pleasant. Here are some situations where you should probably buy one.

If You’re Away From Home Often

If you work long hours and have other commitments that keep you away from home, a self-cleaning litter box is a big help. It will do the scooping while you’re away.

If You Have Multiple Cats

There’s an old saying that cats are like potato chips: You can never have just one. If that fits you, a self-cleaning litter box can help cut down on a lot of your work.

Cat experts recommend a box for each cat plus one extra. This helps keep the boxes clean and prevents cats from fighting with each other over access to the litter box.

If You Have Physical Limitations

If squatting on the floor and scooping is hard for you, a self-cleaning litter box is a necessity. People who can’t reach the box because of physical limitations can enjoy cat companionship more easily with one of these boxes.

Keep It Clean

Self-cleaning cat litter boxes are ideal for people with several cats or anyone who wants to make life with a cat easier. They cut down on litter smells and make it easier to give your cats the clean, sanitary litter box they deserve.

Self-Cleaning Litter Boxes: Reviewed for 2021 FAQs (Frequently Asked Questions) 

Do self-cleaning litter boxes take special litter?

Some of these products require special litter, but we didn’t include these on our list. Many of them use scented or “crystal” litter types, which many cats dislike. We felt getting kitties to use a new litter system would be hard enough without also introducing a new litter. It’s far more convenient to use regular clumping litter.

How often should you change a self-cleaning litter box?

Like any litter box, your self-cleaning box needs regular maintenance. You should wash it once every two weeks. After unplugging it, remove the litter bowl or box. Wash it in warm water and mild soap. Let it dry before refilling it with fresh litter. This is sanitary for your pet, and it helps cut down on odors.

Are self-cleaning litter boxes worth it?

A clean litter box makes life easier for you and your pet. If keeping it clean is difficult for any reason, a self-cleaning litter box is worth it. These boxes save you time and effort. They also ensure your kitty never has to worry if you’ll have the time or ability to keep the box clean.

The boxes on our list—except the CatGenie—all cost under $150. We think they’re an affordable way to make life with a cat easier and more pleasant.

Are self-cleaning litter boxes bad?

The only bad thing about them is getting your cat used to them. It takes time and patience to get your cat used to the new machine. Once they start, however, they tend to like having a consistently clean, fresh litter box.
