FAQ

FAQ

  • What makes Litter-Robot 4 better than other self-cleaning litter boxes?

    Our investments in engineering and American assembly operations ensure we deliver the best to pet parents worldwide. With over 25 years of customer feedback driving product innovation, Litter-Robot 4 features new sensors and technology for enhanced odor control, cat safety, and real-time tracking of waste and litter levels through the Whisker app.

    With over 65,000 5-star reviews, Litter-Robot is the highest-rated self-cleaning litter box for cats, proving not only the quality of our products but also their longevity. 

  • How does Litter-Robot 4 compare to Litter-Robot 3 Connect?

    Core features of Litter-Robot models have always included a patented sifting system, odor 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 neutralize litter box odors 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 maximize cat comfort. Learn more with our Litter-Robot 3 Connect vs Litter-Robot 4 comparison guide.

  • Will my cat actually use Litter-Robot 4?

    We estimate that over 96% of cat households acclimate to Litter-Robot and most cats use Litter-Robot within several days to a week of setting it up. It's natural for some cats to be initially uncertain or wary of new objects in their territory. 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.

    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.

  • Is Litter-Robot 4 safe for my cat? 

    Yes, Litter-Robot was designed with your cat’s safety in mind. If your cat tries to enter the globe while it is rotating, Litter-Robot will stop immediately. 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.

  • Do the bezel patterns of the product match exactly with the images on the website?

    While we strive to accurately represent our product's colors and bezel patterns on our website, please note that due to differences in monitors and lighting conditions, the actual bezel patterns may vary slightly in person and there may be subtle variations in the final product.

  • 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®.

  • Can large cats use Litter-Robot 4?

    Litter-Robot 4 is suitable for most cats, including large breeds like Maine Coons or Norwegian Forest cats, making it one of the best litter boxes for large 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.

  • 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. 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. 

  • 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.

  • 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 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. 

  • 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.

  • Litter-Robot 4 LitterHopper™ FAQs

    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 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 at the start of 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 and Bonnet?

    No tools are required: Download the installation guide to 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. It dispenses roughly half a cup of litter at a time, for a total of approximately 25 dispenses. (Note: The LitterHopper does not dispense litter during every cleaning cycle, only when litter levels drop below optimal.)

    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™?

    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.

    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?

    The LitterHopper automatically includes a 1-year warranty, regardless of whether your Litter-Robot 4 is still under warranty, and is not eligible for coverage under our 3-year 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 at the start of the NEXT clean cycle. For further troubleshooting, visit our support portal.

    What do I do with my original Litter-Robot 4 Bonnet?

    Feel free to recycle or throw away your original bonnet. (Be sure to follow local regulations.) Or you can store it in the box your LitterHopper arrived in for safekeeping.

    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 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.

    Can I use the Litter-Robot 4 Backup Battery with the LitterHopper?

    No, the backup battery is not compatible with the LitterHopper.
