The Litter-Robot by Whisker is the best-known self-cleaning litter box: it sifts waste automatically after every visit, seals it in a drawer and ends daily scooping for good.
Litter-Robot 4 uses a patented rotating globe that, a few minutes after your cat leaves, separates clumps from clean litter and drops them into a sealed, carbon-filtered waste drawer. The Whisker app tracks each cat’s visits, weight and litter level, sends alerts when the drawer is full, and supports multiple cats with individual profiles. A quiet cycle, safety sensors that pause rotation when a cat is detected, and a night light make it practical for everyday homes. Whisker also sells the Feeder-Robot automatic pet feeder and Litter-Robot furniture and accessories.
One waste-drawer bag typically lasts about a week for a single cat, and the rotating globe design means cats always step onto a clean bed of litter rather than a used one. Whisker backs the Litter-Robot with US-based support and a deep catalog of replacement parts, which matters for an appliance at this price that you will own for years.
Litter-Robot 4 starts at $699 as a one-time purchase, with bundles adding extended warranty and supplies costing more; the Feeder-Robot is about $299. The Whisker app is free with no subscription required. Whisker offers a 90-day in-home trial and a 1-year warranty (extendable to 3 years).
Cat owners — especially multi-cat households — who want to eliminate daily scooping, cut litter-box odor and keep an eye on their cats’ bathroom habits and weight.
