How It Works


The Litter-Robot knows when your cat is inside the unit and when it’s time to clean up. Once your cat exits, a timer counts down allowing litter to clump before a cleaning cycle begins. As the globe slowly rotates, the patented sifting system separates the clean litter from the clumps, and drops the waste into a carbon-filtered drawer in the base. The globe returns to the home position, leaving a clean, level bed of litter for the next use. Empty the waste drawer and add litter as needed. It’s that simple!

The Litter Box Reimagined

The Litter-Robot’s automatic movement relies on the cat sensor, a weight-sensitive switch that detects when your cat enters or exits the unit. At any time, when weight greater than 5 pounds is detected within the globe, the globe will not move, or if the globe is already moving, it will stop. You can stop a cleaning cycle by pressing any of the three buttons. After pausing the cycle, you can abort it completely by pressing either the Empty or Reset buttons. The cat sensor does the work for you and keeps your cat safe.

With the Litter-Robot, maintenance is easy and infrequent. We recommend emptying the waste drawer once every 7-10 days for a single cat household, and more often if you have multiple cats. The Litter-Robot III Open Air waste drawer is equipped with infrared emitters and sensors that detect the level of waste after each cleaning cycle. When the waste drawer is full, the blue light on the control panel will flash, indicating it’s time to empty.

You can use kitchen garbage bags, large grocery bags, or Litter-Robot custom-fit, biodegradable Waste Drawer Liners to line the waste drawer. Simply slide out the drawer, gather the old bag, and discard it. Open a new bag, roll down the edges, and press them into the tabs on the waste drawer starting at the back. Cleaning your cat’s litter box is as easy as emptying the garbage!

We recommend checking the litter level each time you empty the waste drawer. Through the entryway, add a few cups of any clumping litter and spread it flat, so it meets the raised fill line inside the globe. You don’t need to change out the entire bed of litter. The Litter-Robot’s efficient sifting system preserves a maximal amount of clean litter each time it cycles, so you’ll find it lasts much longer. Customers often report savings up to 50% on their annual litter costs.
