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. 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. We suggest all-natural premium cat litter for Litter-Robot.
What accessories are available for Litter-Robot 4?The Litter-Robot 4 has many custom-fit accessories to enhance your experience. It includes a standard fence, but you can purchase the Mini Fence if you'd prefer a smaller fence. You can also install a webcam of your choice for better visibility into kitty's bathroom habits using the Litter-Robot 4 Camera Mount . If your Litter-Robot 4 sits on carpet and you want to improve the accuracy of SmartScale™ weight readings, try the Litter-Robot 4 Carpet Tray . Check out odor control components such as OdorTrap™ Packs or Litter-Robot 4 Carbon Filters too!
Can I use any type of bag in the waste drawer?Yes, you can use any bag that fits in the waste drawer. However, please note that waste level readings may be inaccurate when using a dark bag, especially when the drawer is empty. As clumps start to collect in the drawer, the readings will become more accurate. For the most precise waste drawer readings and a seamless experience, we highly recommend using Litter-Robot Waste Liners.
Can I purchase a ramp for Litter-Robot 4?

Please view our Litter-Robot 4 shipping schedule.
Your order will be prioritized in our queue based on your order date. You can reference your order confirmation email if you’re unsure of your order date. You will also receive email confirmation when your unit ships.
Can Litter-Robot 4 be used on carpet or uneven surfaces?
Yes. However, SmartScale™ technology to record cat weight is most accurate on a firm surface, not carpeting. If you plan to use Litter-Robot 4 on carpet that's 3mm+ thick or on uneven flooring, you can improve the accuracy of SmartScale™ weight readings by purchasing our specially designed Carpet Tray that sits between the unit and the floor. The carpet tray is not required for Litter-Robot 4 to function.
How do I update my firmware?
The Litter-Robot 4 is able to receive over-the-air firmware updates as Whisker releases new functionality and enhancements. You'll need to update your firmware manually within the Whisker App. You can visit here for detailed steps.
