Ensure proper placement

Your Litter-Robot comes fully assembled and ready to use. Get started by following the steps below.

If possible, place Litter-Robot in the same location as the old litter box (at least during transition).
Make sure the unit is on a firm, level surface in a cool, dry location.
If the unit is placed on carpet or uneven flooring, you will need to use our Carpet Tray accessory to improve the accuracy of weight readings.
Locate the unit near a power outlet. Ensure the unit isn’t pushed against a wall or into a corner.
Place litter mats or rugs in front of the unit.

Add clumping litter

Litter-Robot’s litter sifting system requires clumping litter. Note: Translucent or white-colored litter (most often seen in crystal litter) may impact the litter level and Drawer Full Indicator (DFI) accuracy.

What not to use

DO NOT use litters that are strictly absorbent, non-clumping, loose-clumping, newspaper-based, or wood-based pellets.

Don’t overfill

Fill the globe through the opening until the litter is slightly below the raised fill line when spread flat (about 8-10 lbs by weight or 1 gal by volume). Be careful not to overfill the globe.

Plug it in

Plug the small end of the power supply into the socket on the back of the base. Then plug the AC/DC adapter into a wall outlet.

Initial clean cycle

Press the Power button on the control panel. Litter-Robot will perform an initial clean cycle that will last 2 minutes. (Note: During the initial clean cycle, the cat sensor weight scale is disabled to ensure proper calibration.)

How the clean cycle works

When your cat exits, a timer counts down, allowing litter to clump before a clean cycle begins:

When your cat exits Litter-Robot, a timer counts down, allowing the litter to clump before a clean cycle begins.

During the clean cycle, the globe slowly rotates. The patented sifting process separates the clumps from the clean litter.

The globe returns to the home position, leaving a clean bed of litter for the next use.

Simply empty the waste drawer when indicated by the app or the control panel, and add litter as needed.

Screens may vary as app gets updated.

Introducing your cat to Litter-Robot

Most likely, your cat will quickly adapt to Litter-Robot. When using in automatic mode, be sure your cat or kitten weighs at least 3 lbs—the weight scale will not recognize cats weighing less than 3 lbs.

Location is key

Place Litter-Robot in the same location as the current litter box, set it up, and make sure it is turned off. Give your cats a day or two to explore Litter-Robot.

Familiar scents

Add a scoop of litter from the old litter box to Litter-Robot to provide a familiar scent for your cat.

Use treats

Place treats around Litter-Robot so your cat associates rewards with the unit.

Introduce the clean cycle

Once your cat has used Litter-Robot, power it on with your cat present so they become familiar with the motion and noise while you’re there to reassure them. Turn the unit off again after it cycles.

Make the old litter box less attractive

Go as long as possible without cleaning the old litter box (but be sure to closely monitor your cat's litter box activity). Cats prefer a clean litter box and a dirty litter box might persuade them to use the clean Litter-Robot.

Say goodbye to scooping

Once your cats are consistently using Litter-Robot, you can turn the unit on and leave it on to operate in automatic mode.

Empty the waste drawer when indicated

Empty the waste drawer when indicated by the app or the flashing blue light on the control panel. How often you empty the waste drawer 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.

To empty the waste drawer, simply pull out the waste drawer, gather the edges of the liner bag, and dispose. To install a new liner or trash bag, wrap the opening over the perimeter of the waste drawer. Push the remainder of the bag into the bottom of the waste drawer.

Add litter as needed

How often you add litter depends on how many cats use Litter-Robot and how frequently they use it. Litter-Robot uses litter very efficiently since the patented sifting mechanism only removes the clumps. We recommend checking the litter level each time you empty the waste drawer. If the litter is below the raised MAX fill line inside the globe, add just enough litter to meet the line.
