Litter-Robot 4
Make cat-life easier with Litter-Robot 4, the newest, quietest, and smartest automatic litter box for cats. Litter-Robot 4 features advanced litter-sifting technology, reduced litter tracking, and real-time monitoring of waste and litter levels through the Whisker app. The elegant design and wide opening maximizes comfort for cats of all sizes. Just empty the waste drawer and add litter as needed!
NEVER SCOOP AGAIN®
Litter-Robot 4’s patented sifting process quietly separates your cat’s waste from the clean litter, ensuring a fresh bed of litter for every use. Enhanced litter-sifting technology limits dust and provides a clean place for your cat’s paws, while the included fence and step greatly reduce litter tracking out of the box.
MAXIMUM ODOR CONTROL
Litter-Robot 4’s optional OdorTrap™ System neutralizes litter box odors. This system uses the combination of a sealed waste drawer and carbon filter to reduce odor. You can opt to replace the carbon filter with OdorTrap™ Packs to eliminate litter box odors through natural chemistry.
MULTI-CAT FRIENDLY
The MultiCat™ Design features a wide opening to maximize cat comfort, providing a clean litter box for households with up to 4 cats of any breed or size. This sleek, compact design has the same footprint as a traditional large litter pan.
SMARTER PET CARE
Litter-Robot 4 lets you connect to the Whisker app to monitor litter box activity, view stats, and receive custom alerts right from your phone. Our sophisticated software tracks litter levels, waste levels, and your cat’s weight in real time.
At first I was convinced that I would be abducted by this spaceship. Then I found out it just wants my poop! Now every time I use the litter box, I have a clean place to go!

Why is Litter-Robot the highest-rated self-cleaning litter box in the world?
We invest in engineering and American assembly operations to ensure that we deliver the best to pet parents worldwide! With tens of thousands of reviews rating Litter-Robot five stars, cats and cat parents alike love the product. Cat parents love that Litter-Robot reduces or even eliminates litter box odors throughout their home, that they're buying less litter thanks to the efficient clean cycle, and that they finally have freedom from scooping the litter box.
Will my cat actually use Litter-Robot 4?
Most likely. Many cats use Litter-Robot within several days to a week of setting it up. Those already familiar with a covered litter box may be quicker to investigate Litter-Robot 4. The trick is to ease your cat into transitioning to Litter-Robot. You can avoid startling your kitty by leaving Litter-Robot switched off until you notice your cat has used it. We recommend that you place Litter-Robot in the same location as the old litter box. You can leave the old litter box near Litter-Robot for a short time. Take a cup of litter from the old litter box and add it to the clean litter in Litter-Robot. The scent will be familiar, and your cat should be inclined to check it out.

Will Litter-Robot 4 eliminate litter box odors?
Litter-Robot 4 features an optional OdorTrap™ System designed to neutralize litter box odors. This system uses the combination of a sealed waste drawer and carbon filter to reduce odor. You can opt to replace the carbon filter with OdorTrap™ Packs to eliminate litter box odors through natural chemistry. Most users suggest that Litter-Robot drastically reduces and or even eliminates litter box odors.
Can kittens use Litter-Robot 4?
Yes. Litter-Robot 4 uses laser and weight sensor technology to detect when your cat enters and exits the globe, which triggers the countdown timer and cleaning cycle. The SmartScale™will not recognize kittens that weigh less than 3 lbs. Therefore, kittens that weigh less than 3 lbs can use Litter-Robot 4, but not in automatic mode. Until they weigh enough, we recommend using your Litter-Robot in "semi-automatic" mode to keep your kitten safe and relieve you from litter box scooping. For "semi-automatic" mode, leave Litter-Robot powered off or unplugged. When you see your kitten has used it, wait about 7 minutes for the waste to clump, then power it on. Litter-Robot will automatically perform a clean cycle. Afterward, power it off again. Continue this supervised, semi-automatic mode until your kittens have gained sufficient weight to activate the SmartScale™.
Does Litter-Robot 4 have a weight limit?
No, Litter-Robot 4 does not have a weight limit. With entryway dimensions of 15.75"H x 15.75"W and interior globe dimensions of 15"-17"H (depending on litter level) x 19"W x 18"D, almost any domestic cat can fit comfortably inside the globe.
Does Litter-Robot 4 require special litter?
No, Litter-Robot 4 does not require special litter. Litter-Robot works well with almost any clumping or scoopable litter. However, translucent or white-colored litter (most often seen in crystal litter) may impact the litter level and Drawer Full Indicator (DFI) accuracy in Litter-Robot 4. Litter-Robot is not compatible with litters that are strictly absorbent, non-clumping, loose-clumping, newspaper-based, or wood-based pellets. We suggest all-natural GreatLitter® for Litter-Robot.What accessories are available for Litter-Robot 4?

How is Scoops Saved calculated?
For each cycle, the tracker increments the Scoops Saved count by one, estimating the total number of scoops you’ve avoided. The count may vary with the occasional cycle that does not scoop litter or cycles that clean up multiple cat bathroom visits, but on average, each cycle represents one scoop saved!My Scoops Saved number doesn’t look right; what can I do?
If your scoops saved doesn’t look right you can reset it back to zero by navigating to your robot settings screen and clicking the option to reset your scoops saved. Please note resetting your scoops saved cannot be reversed!
