Never scoop again

Same footprint as a traditional large litter pan. No need to make space or elaborate installation plans. Litter-Robot’s patented sifting process quietly separates kitty's waste from the clean litter, ensuring a fresh bed of litter for every use. Get back time every day by not scooping and use less cat litter. The control panel features 5 buttons and an LED display for easy operation.

Maximum odor control

The Litter-Robot 4 features a sealed waste drawer and carbon filter which help reduce litter box odors. The flexible Carbon Filter pad sits directly over the Waste Drawer to absorb odors. Under normal use, one filter should last approximately 1 month. The Carbon Filter is not required for the unit to function.

You can opt to replace the carbon filter with Whisker OdorTrap 2-Pack (purchased separately) and the Whisker OdorTrap Pod with OdorTrap Pack System (purchased separately) designed to neutralize litter box odors. 

Multi-cat friendly

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 sleek, compact 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. Laser and weight sensor technology detects cats weighing 3+ lbs. The integrated SafeCat™ System continuously analyzes 4 zones to ensure kitty’s safety.

Cleaner paws, tidier home

Enhanced litter-sifting technology limits dust and ensures a clean place for kitty’s paws, while the included fence greatly reduces litter tracking out of the box. Litter-Robot 4 does not require special litter. Use any clumping cat litter and regular trash bag. Litter-Robot works well with almost any clumping or scoopable litter. Litter beads and crystals that are small enough to pass through the screen will also work. Litter-Robot is not compatible with litters that are strictly absorbent, non-clumping, loose-clumping, newspaper-based, or wood-based pellets.

One word from a daddy of 15 cats: Perfect!

We have 15 cats, and I ordered 5 Litter-Robot 4 units. As a cat daddy of 15, I can really help spread the word that this lovely device is indeed a true joy. What a brilliant project! It DOES really work, and all 15 cats are happily and literally bombarding all units.

Not only does it give us more freedom to be away from our home for more than 24 hours, Litter-Robot 4 also improves our cat's quality of life, because now they never encounter dirty litter when they're going to use their litterboxes.

We're based in Brazil, and I am delighted that RobotShop is an authorized reseller for Whisker products -- And replacement parts too! Their care with handling and shipping made all the difference after my first purchase.

I like!

I already own a Litter-Robot 3 and wouldn't go back for the world. Bought this one because about 2" less in width and fits perfectly where the LR3 couldn't. Super fast delivery, ordered yesterday and received today! Compared to the LR3, it does even less noise Yes it's expensive but I've had cats all my life (I'm 54) and it's life changing For me it's good money Just FYI, I've had the Cat Genie before, believing it would be less maintenance, but after having the Litter-Robot, I highly recommend the latter over the Cat Genie.

Amazing product

So far so good... it's worth the $$$
