Litter‑Robot 4

Most likely. Many cats use Litter‑Robot within several days to a week of setting it up. Litter‑Robot 4 is designed to be as cat-friendly as possible, featuring QuietSift® technology that minimizes noise during the cleaning cycle. The cleaning cycle will only begin minutes after your cat has exited the automatic litter box. You can also set the cleaning cycle delay to as long as 30 minutes, which may better suit skittish cats. With a little patience and encouragement, most cats will quickly adapt to Litter‑Robot 4.

It is important to slowly transition your cat to using Litter-Robot. The trick is to ease your cat into transitioning to Litter‑Robot. You can avoid startling your cat 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. Many cats use Litter-Robot within a few days to a week of setting it up.

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®.

Litter‑Robot 4 is the latest evolution of the highest-rated WiFi-enabled, automatic, self-cleaning litter box for cats. With over 25 years of customer feedback driving product innovation, Litter‑Robot 4 features new sensor and litter-sifting technology for enhanced litter box odor control and cat safety. Paired with the Whisker app, Litter-Robot 4 can provide insights that help you better understand and care for your cat including real-time updates on weight, habits, and behavior right from your phone.

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 litter box odors. You can opt to replace the carbon filter with OdorTrap® Packs to eliminate odors through natural chemistry. Most users suggest that Litter‑Robot drastically reduces and or even eliminates litter box odors.

Yes. Because Litter-Robot automatically cleans after each use, your cat is not walking through dirty litter that can stick to their paws and be tracked out of the litter box. That said, the type of cat litter you use can make a difference in general litter tracking. Litter-Robot 4 comes standard with a fence and step to reduce litter tracking out of the globe.

Yes, Litter-Robot was designed with your cat’s safety in mind. Litter-Robot 4 features enhanced safety technology known as the SafeCat System with OmniSense® Detection that uses lasers to continuously analyze four safety zones, weight sensors, and anti-pinch software for enhanced cat detection. If your cat tries to enter the globe while it is rotating, Litter-Robot will stop immediately.

Yes. Litter-Robot 4 is suitable for cats that weigh between 3 and 25 lbs, including large breeds like Maine Coons or Norwegian Forest cats. With entryway dimensions of 15.75’’ x 15.75” and interior globe dimensions of 15”-17” H (depending on litter level) x 19.00” W x 18.00” D, almost any domestic cat can fit comfortably inside the globe.

No, Litter‑Robot 4 does not require special litter. Litter‑Robot works well with almost any clumping or scoopable litter. We suggest litter that is formulated specifically for Litter-Robot, including GreatLitter® or Tidy Cats® Designed for Litter-Robot®.. 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.
