After your cat leaves the device triggering the “Countdown Timer” and cleaning cycle, your Litter-Robot will save you the trouble of scooping. Its automatic sifting process will promptly remove waste clumps from the litter, providing a clean, level bed of litter for the next use.

All models of the Litter-Robot are perfect for multiple cats because they self-clean after each use.

Just keep in mind, the more cats using it means the more waste below. So, be sure you empty the waste drawer more frequently.

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.

Cats that weigh 5 pounds or less will not activate the Cat Sensor and therefore should not use the Litter-Robot in Automatic Mode.

Instead, Auto-Pets recommends you use a “semi-automatic” mode where you keep the device turned off, and then turn it back on after your lighter kitty has used the device and the waste has had time to fully clump. This process would just need to be done until your kitten or cat has grown to 5 pounds or more.

“The encapsulated clumps, hidden waste drawer, and carbon filter system go above and beyond isolating the waste and litter box odors.”

“The concealed Litter-Robot waste drawer was designed to prevent mold growth, thereby controlling and nearly eliminating that telltale litter box smell. Waste is still waste, so we recommend emptying the waste drawer once every 7-10 days for a single cat household.”

Proprietary liners sold by Auto-Pets aren’t required. You can use any bag of your choice — as long as it fits.

You’ll find that your favorite 10 to 13-gallon kitchen garbage bags or large plastic grocery bags will work nicely.

“Works well with almost any clumping or scoopable litter. Litter beads and crystals that are small enough to pass through the screen will also work.

The Litter-Robot is not compatible with litters that are strictly absorbent, non-clumping, loose clumping, newspaper-based, or wood-based pellets. You’ll find these incompatible litters create a muddy mess and interfere with the sifting process.”

The consistent sifting out of clumped waste every cleaning cycle leaves a maximal amount of clean litter behind, so you will find your litter lasts much longer.

“Customers often report savings up to 50% on their annual litter costs.”

You won’t need any other accessories, tools or diplomas to make this work.

You add the litter, plug it in, turn it on, and basically replace the liner below about once a week — that’s it.
