A litter box is one of the most essential items in any cat-owning household. While it may seem like a simple piece of pet furniture, a litter box plays a crucial role in supporting a cat’s physical health, emotional well-being, and natural instincts. Providing a clean, safe, and accessible litter box is key to raising a happy, well-adjusted indoor cat.
Cats have a strong instinct to bury their waste—a behavior rooted in survival. In the wild, this helps them avoid attracting predators and maintain peaceful boundaries with other animals. A litter box filled with a soft, scoopable material allows indoor cats to act on this instinct. Without a suitable place to dig and bury, cats can become anxious, stressed, or start eliminating in inappropriate places.

Litter-Robot 4: The Convenient, Odor-Free Automatic Litter Box You’ll Love
One of the biggest perks of the Litter-Robot 4 is how it makes managing your cat’s litter box easy and virtually odor-free. Say goodbye to daily scooping and unpleasant smells!
When the waste drawer is full, you’ll get an alert via the control panel light or the convenient app. Simply pull out the drawer, remove the bag filled with waste, toss it, and you’re done. The Litter-Robot 4 comes with three plastic liners to get you started, and many users find that small garbage bags work perfectly once those run out.
One tester shared, “I don’t have to clean it daily, which makes traveling so much easier. We went on a week-long trip during testing, and our cat sitter loved not having to worry about cleaning the litter — she had more time to play with our cats!”
While the Litter-Robot 4 does a fantastic job at reducing odors, some users noticed a slight smell during testing. This is because it separates solid waste into a sealed compartment, which—unlike traditional litter that absorbs odors—can sometimes allow a faint smell to escape. Still, this is a common trait among automatic litter boxes and a small trade-off for the convenience it offers.

Why Testers Say the Litter-Robot 4 Truly Controls Odors—Even in Multi-Cat Homes
According to our testers, any slight odor from the Litter-Robot 4 is hardly noticeable—and still far better than what you’d experience with a traditional litter box. One user said, “I haven’t smelled any cat litter or waste since starting with this litter box. The large interior combined with the sealed waste drawer really does a great job of whisking away odors instantly.”
This automatic litter box is especially valuable for multi-cat households. Waste naturally accumulates faster when you have two or more cats, making regular cleaning a challenge. All our testers with two-cat homes agreed that the Litter-Robot 4 made their lives significantly easier—and their homes much less smelly.
Another big plus? The Litter-Robot 4 is surprisingly quiet. On a popular Reddit thread, nearly every user agreed it’s much quieter than the previous Litter-Robot 3 model. One tester said, “It’s nowhere near as loud as our dishwasher or washer and dryer, so the noise level is totally acceptable—and it definitely doesn’t bother our cats.”
Effortless Setup: How Easy It Is to Get Your Litter-Robot 4 Up and Running
One of the most praised features of the Litter-Robot 4 is how simple it is to set up—our testers and many Reddit users agree: there’s virtually no assembly required. One tester shared, “Out of the box, I just had to plug it in, and it was ready to go.” Another appreciated that it arrives fully assembled, with clear instructions on unboxing.

Here’s a quick 5-step guide to get started:
- Place it properly: Set your Litter-Robot 4 near a power outlet, making sure it’s at least one inch away from walls. Lay down litter mats or rugs in front to catch stray litter, and place it on a firm, level surface.
- Download the app: Control your Litter-Robot remotely and customize settings right from your phone.
- Add the right litter: Use only clumping litter—the Litter-Robot 4 isn’t compatible with non-clumping, loose-clumping, or pellet-based litters like newspaper or wood.
- Start the initial cleaning cycle: Plug in the unit and press the power button to begin the two-minute setup cleaning cycle.
- Introduce your cat: While some cats adjust immediately, others may need a few days. Keep the old litter box nearby for 2–3 days during the transition. One Reddit user even shared a detailed 10-step approach to help their cats get comfortable, noting, “It takes some time, but it’s so worth it in the end!”
How to Use the Litter-Robot 4: Simple, Smart, and Hands-Free
Using the Litter-Robot 4 is incredibly easy — it practically runs itself. Inside, a fabric hammock holds a ready supply of clean litter. After your cat finishes, the spherical unit gently rotates, separating the clumps and filtering the waste into a sealed drawer. The clean litter is then recycled back into the box for your cat’s next visit.
You can control and monitor the unit via the app or the control panel, with options to start a cleaning cycle, reset, or empty the waste drawer. But honestly? The Litter-Robot 4 lives up to its “robot” name by handling most of the work automatically, so you can enjoy a cleaner, fresher litter box with minimal effort.

Cats Love the Litter-Robot 4—Comfort and Convenience for Your Feline Friends
While the Litter-Robot 4 offers incredible benefits for pet parents, it’s important to remember that your cats are the real users—and they benefit from it too!
During a recent week-long trip, our cat sitter appreciated not having to worry about cleaning the litter, which meant more quality playtime with the cats.
One standout feature for cats is the larger entryway. At 15.75 inches wide, the Litter-Robot 4’s opening is over five inches wider than the previous model, making it more comfortable and inviting. One tester said, “My cats absolutely love the size of it. I have two cats, and although it took some adjustment, now they use it much more than their original litter box.” This sentiment is echoed by many Reddit users, who agree that the spacious entry alone makes the Litter-Robot 4 worth the upgrade.
Smart Features of the Litter-Robot 4: Health Monitoring and More
The Litter-Robot 4 isn’t just a self-cleaning litter box—it’s packed with smart features that help you keep tabs on both your cat and their litter. One standout upgrade from the previous model is its ability to monitor your cat’s weight and litter box usage, offering invaluable health insights.
For example, a Reddit user shared how their Litter-Robot 4 helped detect a urinary tract infection (UTI) early:
“We’ve only had our Litter-Robot 4 for a little over a month, and this week it helped us quickly spot a UTI in one of our four cats. Since all our cats have different weights, when the unit logged seven weights for one cat within 15 minutes, I knew something was wrong. Less than 24 hours later, we took a urine sample, started antibiotics and pain meds, and got our little old lady comfortable. The ability to detect this issue so quickly has completely sold me on the LR4.”
This weight-tracking feature is especially useful for multi-cat households, as it associates each weight with a specific cat, helping you monitor their health discreetly and effectively.
Many Redditors who upgraded from the Litter-Robot 3 to the 4 report that both they and their cats prefer the newer model. One commenter summed it up perfectly:
“My cats all prefer the Litter-Robot 4, as do I.”

“It was a tough decision to spend that much money on the Litter-Robot 4, but after weeks of thinking, I bought it. Now, if anything happens to it, I wouldn’t hesitate to replace it—that’s how much it has improved my quality of life.”
