Always at the right level.
Litter-Robot performs its best when litter is at the optimal level. A fuller, deeper litter bed makes clumping more effective while minimizing excess residue, resulting in cleaner, more consistent cycles.
A fresher litter bed, edge to edge.
LitterHopper automatically replenishes litter during cleaning cycles, only when it senses levels are low—helping reduce residue and sticking, and even creating better odor control, keeping paws and your home cleaner.
More capacity, same simplicity.
The Litter-Robot 5 LitterHopper holds 32% more litter than the Litter-Robot 4 LitterHopper, extending the time between refills, making your litter routine even more low-maintenance.
A seamless Whisker app experience.
Your Litter-Robot 5 and LitterHopper appear as one unit in the Whisker app, allowing you to track cycle history and refills in one convenient place. No onboarding required!
Simple setup.
The easy, 2-step installation is tool-free and hassle-free. Once the Hopper is installed, you’ll get a confirmation on-screen, and you’re ready to check another chore off your list.

Frequently asked questions
How it works
How does the LitterHopper® work?
The Litter-Robot 5 LitterHopper is designed to automatically maintain the optimal Litter-Robot 5 litter level within the globe. The default optimal litter bed level inside Litter-Robot 5 is at or just below the MAX fill line inside the globe. Litter-Robot 5 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.
You must update your Litter-Robot 5 to the firmware version 5.9.6 or later and app version 1.38 or later 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.

Does LitterHopper dispense litter after every clean cycle?
No. LitterHopper only dispenses litter during clean cycles when additional litter is needed to maintain optimal levels inside the globe. This helps prevent overfilling while keeping your Litter-Robot 5 ready for every visit.
How do I install the Litter-Robot 5 LitterHopper®?
No tools are required. View the installation guide.
Does the LitterHopper® work with any Litter-Robot model?
No, the Litter-Robot 5 LitterHopper® is only compatible with Litter-Robot 5 and Litter-Robot 5 Pro.
Litter
*What type of cat litter can I use with the LitterHopper®?
We recommend using clay-clumping cat litter with Litter-Robot 5, 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. Learn more about the best litter for Litter-Robot in our dedicated article.
How much cat litter does the LitterHopper® hold and dispense?
The LitterHopper holds approximately 17.3 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 many pounds of litter should be added to Litter-Robot 5 with the LitterHopper®?
We recommend filling your LitterHopper to the MAX fill line since most litters weigh different amounts.
Miscellaneous
Are there any special cleaning instructions?
While cleaning your Litter-Robot 5, be careful that the LitterHopper key (the device used to direct litter from the LitterHopper into Litter-Robot 5) 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 the Whisker support portal.
Is the LitterHopper® included in my Litter-Robot 5 WhiskerCare® Warranty?
The LitterHopper automatically includes a 1-year warranty, regardless of whether your Litter-Robot 5 is still under warranty, and is not eligible for coverage under our 3-year extended warranty.
What do I do with my original Litter-Robot 5 back plate?
We recommend keeping the plate attachment until you are satisfied with your new LitterHopper.
