Litter-Robot. The #1 choice for self-cleaning litter boxes
After your cat exits Litter-Robot, a timer counts down, allowing litter to clump. Then the Litter-Robot globe begins to rotate, using patented sifting technology to automatically and quietly separate the dirty clumps from the clean litter into a sealed waste drawer below—trapping odors while always leaving a fresh bed of litter for your cat.
How often you empty the Litter-Robot waste drawer depends on how many cats you have and which Litter-Robot model you’ve purchased. For single-cat households, you’ll need to empty the waste drawer approximately as follows: Litter-Robot 5/Pro, every 10 days; Litter-Robot 4, every 8 days; Litter-Robot EVO, every 7 days. For every additional cat, divide that figure in half.
No, Litter‑Robot does not require special litter. Litter‑Robot works well with almost any clumping or scoopable litter. We suggest litter that is formulated specifically for Litter-Robot, including GreatLitter® or Tidy Cats® Designed for Litter-Robot®.
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.
Most pet parents agree that cleaning a cat litter box is one of the worst household chores. No cat owner wants to deal with the odors, dust, and physical labor involved in scooping.
The best way to eliminate the chore of scooping is to buy a self-cleaning litter box. Such automatic litter boxes clean the waste after your cat exits, leaving a fresh bed of litter for their next use.
Automatic litter boxes also significantly reduce odors and mess. The cat waste is promptly deposited into a sealed drawer while an enclosed globe and advanced sifting technology limits litter dust and tracking out of the box.
Another great benefit of having a self-cleaning litter box is reducing the amount of litter boxes in homes with multiple cats. While multi-cat households require multiple traditional litter boxes, one self-cleaning litter box is usually suitable for up to four cats.
Which Litter-Robot model is best for you depends on various factors such as number of cats in your household, price point, and desired monitoring capabilities.
