FAQ
What is the WhiskerCare™ Extended Warranty?
The WhiskerCare™ Extended Warranty is a comprehensive protection plan that covers your Litter-Robot from top to bottom for 3 years. Our hassle-free plan covers accidental damage, power surges, mechanical and electrical breakdowns, and software support. You’ll have access to our dedicated customer experience specialists, software experts, and US-based service and repair team. 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.How does the LitterHopper work?
The Litter-Robot 4 LitterHopper is designed to automatically maintain the optimal Litter-Robot 4 litter level within the globe. The default optimal litter bed level inside Litter-Robot 4 is at or just below the MAX fill line inside the globe. Litter-Robot 4 uses OmniSense® Detection to measure the height of the litter bed level at the end of each clean cycle. If the sensors determine that the litter bed level is below optimal, then the LitterHopper will dispense litter into the globe during the NEXT clean cycle.
Note: You must update your Litter-Robot 4 to the latest firmware version through the Whisker app before installing the LitterHopper. If you do not currently use the Whisker app, please download the app and update your firmware.Can I choose a LitterHopper color that’s different from the color I selected for Litter-Robot 4?
No, the LitterHopper will match your selected Litter-Robot 4 color (black or white).
Do the LitterHopper and Litter-Robot 4 ship separately?
Yes.
How do I install the Litter-Robot 4 LitterHopper?
No tools are required: Download the installation guideto make sure you are willing to install this accessory.
What type of cat litter can I use with the LitterHopper?
We recommend using clay-clumping cat litter with Litter-Robot 4, although litter beads and crystals that are small enough to pass through the screen will also work. However, translucent or white-colored litter (most often seen in crystal litter) may impact the litter level and Drawer Full Indicator (DFI) accuracy.
How much cat litter does the LitterHopper hold and dispense?
The LitterHopper holds approximately 13 cups of cat litter. The LitterHopper will dispense litter for up to 20 seconds per cycle. If the litter bed doesn't reach the optimal level in one cycle, the LitterHopper will continue to dispense in the next cycle until the optimal level is reached. (Note: The LitterHopper only dispenses litter when the litter level drops below the optimal level, not during every cleaning cycle.)
How do I know my LitterHopper™ is calibrated to optimal litter levels?
When you initially enable the LitterHopper, ensure the litter level inside the globe is optimal: just below the MAX fill line. Whatever the litter level is when you enable the LitterHopper will automatically be set as the optimal litter level. This means your LitterHopper will not dispense until the litter reaches below that level.
If you need to reset your optimal litter level, please reference the "Calibrate the optimal litter level" section in the Litter-Robot 4: LitterHopper not dispensing support article.How many pounds of litter should be added to Litter-Robot 4 with the LitterHopper™?
Will the Whisker app tell me when the LitterHopper is empty?
Yes, the Whisker app will notify you when your LitterHopper is likely empty. The app closely monitors your litter bed level. If it detects a decreasing litter bed level trend over several cleaning cycles, the app will notify you that litter levels are getting low, indicating that the LitterHopper is likely empty. Please note: We are continuing to improve upon this feature; in some cases, the feature may not work as intended.
Is the LitterHopper included in my Litter-Robot 4 WhiskerCare™ Warranty?
Yes; when you purchase this bundle, the LitterHopper is automatically covered under your WhiskerCare™ Extended Warranty.
Is the LitterHopper™ anti-tip guard compatible with the Litter-Robot 4 Carpet Tray?
Yes, they are compatible. The carpet tray includes a support extension for the anti-tip guard.
Are there any special cleaning instructions?
While cleaning your Litter-Robot 4, be careful that the LitterHopper key (the device used to direct litter from the LitterHopper into Litter-Robot 4) doesn’t fall out. Note that the key is designed to fit loosely in the globe, thus allowing the globe to rotate freely around it. We recommend regularly cleaning the LitterHopper dispensing area with a dry cloth or vacuum to avoid buildup of dust, loose litter, or clumps.
Why didn’t the LitterHopper add litter to my globe?
When you initially install the LitterHopper, you’ll need to start with a full bed of litter that is at or just below the MAX fill line. Litter will be added ONLY when needed and only during the NEXT clean cycle. For further troubleshooting, visit our support portal.
Can I return the LitterHopper but keep my Litter-Robot 4?
If you purchased the LitterHopper at the same time as your Litter-Robot 4, you will need to return your entire unit (return shipping fee required) for a LitterHopper refund. We will then ship a standard Litter-Robot 4 to you.
Weight-based ID disclaimer
When Litter-Robot 4 is equipped with the LitterHopper, weight-based ID technology will not function for cats that weigh more than 25 pounds.
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.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 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.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 (6 included with this bundle) to eliminate litter box odors through natural chemistry. Most users suggest that Litter-Robot drastically reduces and or even eliminates litter box odors.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). To connect to a shared network (apartment complexes, college dorms, etc.) provide your unit’s MAC address shown on the QR code sticker to the shared network administrator.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, level surface, not carpeting. If you plan to use Litter-Robot 4 on carpet or uneven flooring, please purchase our Carpet Tray accessory. This will sit between the unit and the floor and improve the accuracy of SmartScale® weight readings when on carpet or uneven surfaces.User Manuals

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!If I already have an account on litter-robot.com, do I have to log in again when using the app to make purchases?

This depends on the type of litter you're using. For example, with the recommended standard-weight clay-clumping litter, approximately 17 pounds of litter is used when added to both the Litter-Robot 4 globe (just below the MAX fill line) and the LitterHopper.
