Get two chores done with one bundle. Litter-Robot 4 with LitterHopper is our top self-cleaning litter box solution with automatic litter refills. You’ll never have to scoop again, and your cat will always have a fresh bed of litter at the optimal level. This Litter-Robot bundle includes:
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.
No, the LitterHopper will match your selected Litter-Robot 4 color (black or white).
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. Read our best litter for Litter-Robot guide to learn more.
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.)
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.
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.
Yes; when you purchase this bundle, the LitterHopper® is automatically covered under your WhiskerCare™ Extended Warranty.
Yes, they are compatible. The carpet tray includes a support extension for the anti-tip guard.
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.
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.
Yes.
When Litter-Robot 4 is equipped with the LitterHopper, weight-based ID technology will not function for cats that weigh more than 25 pounds.

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.
