FAQ
What makes Litter-Robot 4 different from other self-cleaning litter boxes?
Litter-Robot 4 is the latest evolution of the highest-rated WiFi-enabled, automatic, self-cleaning litter box for cats. With over 20 years of customer feedback driving product innovation, Litter-Robot 4 features new sensor and litter-sifting technology for enhanced odour control, cat safety, and real-time tracking of waste and litter levels through the Whisker app.
How does Litter-Robot 4 compare to Litter-Robot 3 Connect?
Core features of Litter-Robot models have always included a patented sifting system, odour management, multi-cat design, cat safety features, and easy-to-clean modular components. The new Litter-Robot 4 advances these core features with the latest technology, including the optional OdorTrap™ System to neutralise litter box odours and the SafeCat System with OmniSense™ Detection for enhanced safety and real-time tracking of waste and litter levels. Litter-Robot 4 also features a QuietSift™ cleaning cycle, an enlarged waste drawer, and a wider opening to maximise cat comfort.

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 odours 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. Learn more about acclimating your cat.
Will Litter-Robot 4 eliminate litter box odours?
Litter-Robot 4 features an optional OdorTrap™ System designed to neutralise litter box odours. This system uses the combination of a sealed waste drawer and carbon filter to reduce odour. You can opt to replace the carbon filter with OdorTrap™ Packs to eliminate litter box odours through natural chemistry. Most users suggest that Litter-Robot drastically reduces and or even eliminates litter box odours.
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 recognise kittens that weigh less than 1.3 kgs. Therefore, kittens that weigh less than 1.3 kgs 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 40cm Height x 40 cm Width and interior globe dimensions of 38-43 cm Height (depending on litter level) x 48.2 cm Width x 45.7 cm Depth, 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 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. 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 odour 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 Drawer Liners.Can I purchase a ramp for Litter-Robot 4?
The Litter-Robot 4 Ramp will most likely be available for purchase in early 2023. If you require a ramp for your Litter-Robot 4 in the meantime, check out these options:
- If you already own a Litter-Robot 3 Ramp, purchase our Ramp Adapter.
- If you don’t own a ramp, purchase our Litter-Robot 3 Ramp + Adapter Kit.
What is the WhiskerCare™ 1-Year Warranty?
WhiskerCare™ is a comprehensive protection plan that covers your Litter-Robot from top to bottom for 1 year. An extended plan is available for purchase. Our hassle-free plan covers accidental damage, power surges, mechanical and electrical breakdowns, and software support. You’ll have access to our dedicated US-based customer experience and software experts. During your warranty period, we will resolve Litter-Robot issues at no charge, including free shipping both ways. There are never deductibles or hidden fees.
What happens if there are other cats in the home without pet profiles using the Litter-Robot 4?
When other cats without a pet profile use the Litter-Robot 4, weight readings will be seen as unhealthy data. When too many data points are classified as unhealthy, SmartScale will be turned off. If you are an individual or organisation that fosters or rescues cats, you’ll need to set up a Pet Profile for each cat in order for SmartScale to function and filter data properly.
Can I use the app with both iOS and Android?
The Whisker app is compatible with Apple mobile devices with iOS 13.0 or greater and Android devices 8.0 or greater. Both the iOS app and the Android app are available to download.
Can I connect the app to multiple Litter-Robots?
Yes. You can onboard multiple WiFi-enabled Litter-Robots to the same app. If others in your household want to use the app, they can simply download the app to their device and log in with the same account.
Will Litter-Robot 4 connect to my WiFi network?
Litter-Robot 4 requires a 2.4 GHz WiFi signal and IPv4 or IPv6 addressing (5 GHz band not supported).
When will my Litter-Robot 4 ship?
Please view our Litter-Robot 4 shipping schedule.
Your order will be prioritised 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.

*Cat Recognition and Weight Disclaimer
Some features not available until late 2022. Additional hardware required to distinguish cats of similar size. SmartScale™ technology to record cat weight is most accurate on a firm surface, not carpeting.
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!
