What Makes Litter-Robot Different?

Unlike traditional self-cleaning litter boxes that use rakes or trays, the Litter-Robot features a patented rotating globe.

After your cat exits, the globe slowly rotates, separating clean litter from waste.

The waste is deposited into a sealed drawer, while the clean litter is returned to the globe for reuse.

This process significantly reduces:

• Daily scooping
• Odors
• Litter waste
• Cleaning frequency
