How does the Litter-Robot 3 Connect work?

With the Litter-Robot 3 Connect, life is a lot simpler. Don’t waste any more of your time scooping, cleaning, or smelling your litter box with the help of this top-rated self-cleaning litter box. Here’s how this connected pet robot appliance works! 

1. Download the app 

Once you download the app, allow the app to send push notifications to your smartphone. That way, you’ll know when your Litter-Robot needs your attention. With the app, you’ll also have the ability to connect multiple units and control them all from the same app. 

2. Customize alerts 

You can set up customizable alerts within the app, making it easy for you to view the waste drawer levels and receive notifications whenever the drawer needs to be emptied. Customizable alerts will also tell you when your Litter-Robot is cycling or if the unit is completely paused.

3. Monitor bathroom behaviors 

The app will even let you view your cats’ usage of the litter box and show you trends regarding their bathroom behaviors. 

4. Save time

Self-cleaning capabilities mean you won’t have to spend all day scooping poop out of the litter box. After your cat exits the Litter-Robot, the sifting process will automatically begin. Waste will be separated from the clean litter and the clumps will be deposited into the waste drawer. 

The carbon filter in the waste drawer will also help you with managing and reducing odors. The filter is easy to change as necessary. The self-cleaning feature will not only save you time, it’ll also help reduce your litter usage by up to 50%. 

5. Enjoy automation

With features like sleep mode, your Litter-Robot won’t cycle at night. The sleep mode lasts for eight hours, so you’ll want to time it to your liking. But during the day, you can set an adjustable cycle timer that will determine how long your Litter-Robot waits before it starts cycling after your cat uses the litter box. The timer can be set for 3, 7, or 15 minutes. 

Litter-Robot 3 Connect FAQ

Whether you’re wondering if this self-cleaning litter box is good for multiple cats or how to clean your automatic litter box, we’re here to answer your questions about the Litter-Robot 3 Connect!

Is Litter-Robot good for multiple cats?

Do you live in a household with multiple cats? No problem! One Litter-Robot unit is suitable for up to four cats. If you have more than four cats, don’t fret: You can connect multiple units to the same app. You’ll also be able to view how often your cats use the litter box. 

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

In general, you should empty the waste drawer once per week if you have one cat or twice per week if there are two or more cats. The litter should be emptied and completely replaced once every 1-3 months. 

Can you use regular cat litter in a self-cleaning litter box?

While you can use regular non-clumping litter in some self-cleaning boxes, non-clumping litter will make it much more difficult for the Litter-Robot’s automatic sifting system to remove waste. Non-clumping litter typically won’t help reduce odors either. It's recommended that you use clay-clumping litter to achieve the best results with the Litter-Robot. 

How often should I change the carbon filter in the waste drawer?

The frequency at which you change the carbon filter is a personal preference. However, it’s recommended that you change the filter at least once every 3-4 months. If you have multiple cats using the same litter box, then you may need to change the filter even more frequently. And if you ever notice a strong odor coming from the unit, you should definitely change the carbon filter! 

How do you clean an automatic litter box?

Cleaning this automatic litter box is much easier than cleaning a traditional litter box. All you have to do is remove the liner bag from the waste drawer and replace it with a fresh liner. It’s as easy as taking out the garbage!

When performing a full cleaning, wipe down the inside of the unit after you empty the old litter. It’s best to use Litter-Robot cleaner wipes or a cloth paired with a gentle cleanser.

Great for multiple cats

An added benefit of the Litter-Robot 3 Connect is that one unit is suitable for up to four cats. With the app, you can also view how often your cats are using their Litter-Robot. The app will show you trends regarding their bathroom behavior so you’ll know how often the litter box is being used and when the waste drawer needs to be emptied.

18-month warranty

Accidents happen. That’s why we back our Litter-Robot 3 Connect with an 18-month warranty that begins on the day the unit is shipped to you. During the warranty period, we’ll repair your Litter-Robot at no charge to you. We cover the costs of parts, labor, and shipping within the 48 contiguous states.

Designed & assembled in the USA 

Unlike many other self-cleaning litter boxes on the market, the Litter-Robot is designed, engineered, assembled, and serviced right here in the USA. The Michigan-based customer service team is dedicated to supporting pet parents at the time they need it! 

WiFi connectivity 

With the app, you’ll never have to worry about the status of your litter box! You’ll have the ability to view the waste drawer level, get push notifications, troubleshoot issues, and see recent usage history from the palm of your hand. The app is currently compatible with Apple mobile devices that have iOS 10.0 or later and Android mobile devices that have version 8.0 or later. 

Odor control

The fully-enclosed waste drawer is equipped with a carbon filter that is designed to reduce unpleasant odors. Say goodbye to smelly litter boxes! The carbon filter is easy to change and only needs to be replaced every few months, unless you notice a strong odor. 


While you don’t need special accessories for your Litter-Robot 3 Connect, you’ll have the added benefit of products like a ramp for easier litter box access, custom-fit drawer liners, a Litter Trap™ Mat, and so much more!


With our cat-sensing technology and a safety system that detects your cat’s weight, you’ll never have to worry about your kitty’s safety. If at any time the weight of your cat is detected inside the globe, the globe will not rotate—or if the globe is already rotating, it will stop. And if your unit stops for any reason, you’ll receive a push notification from the app. 


So, what is the best automatic cat litter box? You tell us! Check out a few of our top competitors to see how the Litter-Robot 3 Connect compares. We hope that this automatic litter box review helps you find the right self-cleaning litter box for you!

Litter-Robot 3 Connect vs PetSafe Ultra

The PetSafe Ultra litter box is a popular self-cleaning litter box on the market. And while it has a raking system that works to dispose of waste, it is a bit smaller than the Litter-Robot 3 Connect and also lacks important features in other areas. 

The PetSafe Ultra only works with silica litter and doesn’t have a top that covers the litter box. Many cat parents report their cats not being a fan of using the PetSafe Ultra litter box, too.  

Finally, while the PetSafe Ultra retails at a lower price than the Litter-Robot, the costs start to add up over time. You can only use PetSafe-brand trays and litter with the litter box. The issue here is that the disposable trays are more expensive and wasteful than drawer liners like the ones used in the Litter-Robot 3 Connect. 

Litter-Robot 3 Connect vs CatGenie AI

The CatGenie AI is a great option for households with multiple cats. While the cost is a bit lower than the Litter-Robot 3 Connect, the look of the CatGenie leaves something to be desired, as it’s designed to look like an actual toilet. 

With the Litter-Robot 3 Connect, all you need is an outlet. CatGenie requires an outlet and a cold-water hookup due to the fact that it doesn’t rake the litter. Instead, it actually flushes waste. 

Instead of using cat litter, the CatGenie uses septic-safe washable granules that never need to be changed. While that may sound convenient, it’s not as simple as it sounds—the granules tend to leave a soapy mess in the bowl before draining out the waste. 

According to customer reviews, the CatGenie is about as loud as a washing machine when it’s flushing and cleaning the litter box. It takes about thirty minutes to fully clean, whereas the Litter-Robot takes no more than three minutes to self-clean. 

However, a major upside to the CatGenie is that it cleans itself out after every use. 

Litter-Robot 3 Connect vs LitterMaid 3.2

The LitterMaid 3.2 is geared towards households with multiple cats. LitterMaid 3.2 has a rectangular pan that uses a raking mechanism to scrape and remove waste from the litter bed.

It also comes with a built-in sensor to detect the presence of cats inside of the litter box. While it does come with a delay mode feature, it only waits 10 minutes after your cat leaves the box to start self-cleaning, as opposed to the three different options you’ll have with the Litter-Robot. 

You can also use the litter of your choice with LitterMaid. However, a downside to the LitterMaid litter box is that waste tends to stick to the rake, which can cause it to clog and jam. Litter-Robot’s rotating design, on the other hand, keeps the unit from clogging.

Unlike Litter-Robot, LitterMaid doesn’t come with any sort of additional smart features. You won’t have access to an app, sleep mode, push notifications, or indications that the drawer is full. 

The difference between the Litter-Robot 3 and the Litter-Robot 3 Connect

The difference between the Litter-Robot 3 and the Litter-Robot 3 Connect is that the Litter-Robot 3 Connect has WiFi capabilities, while the Litter-Robot 3 does not. 

With the Litter-Robot 3 Connect, you’ll have access to the app, which will give you even more freedom from your litter box duties. You can view the waste drawer level, get push notifications, troubleshoot issues, and see your cat’s usage history directly from your phone. 

If you like the Litter-Robot, you’ll love the Feeder-Robot

The Feeder-Robot is an automatic pet feeder that dispenses food to your pets with the press of a button on the app or the control panel. The app will give you the ability to customize your pet’s mealtime schedule, even when you aren't home. 

You’ll never forget to feed again! The app displays how much food is in the container, and the unit can hold up to 32 cups of food at a time. Equipped with anti-jam technology, this automatic feeder is a completely reliable option. 

The Feeder-Robot comes with an 18-month warranty and a 90-day in-home trial. You can customize your Feeder-Robot design to suit your home decor: Choose between black and white panels, and either a clear plastic tint or a smoke plastic tint. You can also add a glass or stainless steel bowl to your purchase.
