Hi Coraline,
Here are the recommendation from Litter-Robot:
Will the Litter-Robot eliminate all litter box odor?
No, the Litter-Robot will not eliminate all litter box odor. However, because waste is promptly removed and contained in the base, typical litter box odor will be reduced significantly. Additionally, a large carbon filter located in the front of the waste drawer absorbs odors and moisture to discourage mold growth (a major culprit of that telltale litter box smell). The amount of odor control the Litter-Robot will provide depends on the amount of odor created—by how many cats use it, what type of litter you use, and your cats’ diets, among other things. Of course, the more often you empty the waste drawer, the less opportunity there is for odor to escape. That said, if you empty the waste drawer and notice the Litter-Robot is still a source of unpleasant odors, we recommend changing out the bed of litter completely, deep-cleaning the Litter-Robot twice per year, and replacing the carbon filter and seal strips as needed. It is also worth noting that scented litters are generally not as effective at absorbing odors as unscented litter. Instead, we recommend an unscented, odor-trapping, natural litter like Litterbox.com All Natural Clumping Litter.
How often do I need to empty the waste drawer?
This depends on the number and size of your cats. For two average-sized cats, twice per week is typical. For a single cat, once per week is usually sufficient.
How do I clean the Litter-Robot exterior?
Cleaning the Litter-Robot exterior is easy. Just remove the globe and the drawer and give them a sponge bath, or take them outside for deep-cleaning with the garden hose. All other surfaces can be wiped clean, but should not be submerged. CAUTION: The base and bonnet of the Litter-Robot contain electrical components that should not be submerged.
How often do I have to clean the inside of the globe?
This depends on your personal preference and your cat’s behavior. We recommend cleaning the inside of the globe every one to three months. Learn how to clean your Litter-Robot: 1. Press the Empty button to cycle the globe clockwise, which will allow the litter to fall through the waste port and into the drawer for easy disposal. Sweep any leftover litter toward the waste port. Then, press any button to return the globe to the Home position. Ensure that all litter has been removed from the globe—wet litter turns into messy clay! 2. Turn the Litter-Robot off and unplug the unit. 3. Remove the bonnet: Press and release the snap tabs on both sides of the bonnet, then lift and rotate the bonnet off of the globe and carefully set it aside. 4. Remove the globe: With two hands, lift the globe off the base. 5. Clean the globe with water and a mild soap. There are no electronic components in the globe that can be damaged by soap and water. If the globe has become extremely dirty, it can be soaked and cleaned with a water hose or power washer. 6. Let the globe dry completely before reassembling it to the base and attaching the bonnet. For a quick touchup, you can use a disposable towelette to wipe the inside and upper half of the globe (without removing the litter). The Litter-Robot can be used immediately, since drying is nearly instantaneous.
How much litter do I put in the Litter-Robot?
Fill the globe with approximately 8-10 pounds of litter, until it meets the raised fill line on the black rubber globe liner when spread flat. If there is too much litter in the globe, it will be expelled into the waste drawer during the first few cycles. Since the waste clumps are removed during each cycle, there is no need to put excessive litter in the globe.
I hope this information helped you.
