  • Litter-Robot 4 Self-Cleaning Litter Box by Whisker
  • Suitable for up to 4 cats of any breed or size
  • Allows you to monitor litter and waste levels right from your phone
  • Minimize litter tracking with a complimentary fence
  • Drastically reduce litter box odors
  • Color: Black

The Litter-Robot 4 Automatic Self-Cleaning Litter Box - Black (Refurbished) is the next evolution of the highest-rated WiFi-enabled, automatic, self-cleaning litter box for cats. Stop scooping cat litter, neutralize litter box odors, and give kitty a clean bed of litter every time with Litter-Robot 4.

Elegantly designed to maximize comfort for cats of all sizes, Litter-Robot 4 features advanced litter-sifting technology, the reduced litter tracking, and real-time monitoring of waste and litter levels through the Whisker app.

Never scoop again

Same footprint as a traditional large litter pan. No need to make space or elaborate installation plans. Litter-Robot’s patented sifting process quietly separates kitty's waste from the clean litter, ensuring a fresh bed of litter for every use. Get back time every day by not scooping and using less cat litter. The control panel features 5 buttons and an LED display for easy operation.

Maximum odor control

The Litter-Robot 4 features a sealed waste drawer and carbon filter which help reduce litter box odors. The flexible Carbon Filter pad sits directly over the Waste Drawer to absorb odors. Under normal use, one filter should last approximately 1 month. The Carbon Filter is not required for the unit to function.

You can opt to replace the carbon filter with Whisker OdorTrap 2-Pack (purchased separately) and the Whisker OdorTrap Pod with OdorTrap Pack (purchased separately) designed to neutralize litter box odors.

Multi-cat friendly

Many cats use Litter-Robot within several days to a week of setting it up. Those already familiar with a covered litter box may be quicker to investigate Litter-Robot 4. The sleek, compact MultiCat Design features a wide opening to maximize cat comfort, providing a clean litter box for households with up to 4 cats of any breed or size. Laser and weight sensor technology detect cats weighing 3+ lbs. The integrated SafeCat™ System continuously analyzes 4 zones to ensure the kitty’s safety.

Cleaner paws, tidier home

Enhanced litter-sifting technology limits dust and ensures a clean place for the kitty’s paws, while the included fence greatly reduces litter tracking out of the box. Litter-Robot 4 does not require special litter. Use any clumping cat litter and a regular trash bag. Litter-Robot 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. Litter-Robot is not compatible with litters that are strictly absorbent, non-clumping, loose-clumping, newspaper-based, or wood-based pellets.

Built to Last

The Litter-Robot is an appliance-quality, automated self-cleaning litter box designed to last the nine lives of your cat. Whisker stands behind this litter box with a 12-month full warranty.

30-Day Money-Back Guarantee
