The Litter-Robot EVO Self-Cleaning Litter Box (Black), made by Whisker, is a compact self-cleaning litter box built for households with one to two cats and designed to fit into tighter living spaces without compromising on core functionality. After each cat visit, the globe automatically rotates to sift clumps from clean litter, depositing waste directly into a tightly sealed drawer below. The result is a consistently fresh litter bed that requires no manual scooping and minimal daily maintenance. Built for apartments, condos, and smaller homes, it delivers the same core automatic litter box technology as larger Litter-Robot models in a reduced footprint.
The unit connects to the Whisker app over a 2.4 GHz WiFi network, giving owners remote access to cycle controls, waste drawer status alerts, and cat visit history. A built-in SmartScale® tracks individual cat weights in single-cat households, and the full-color LCD panel provides at-a-glance status updates during setup and daily use. The QuietSift® cleaning cycle runs with minimal noise, making it suitable for skittish cats and shared living environments. Designed for first-time automatic litter box owners as well as experienced users seeking a streamlined solution, the EVO integrates with the broader Whisker accessory ecosystem and supports optional Whisker+ membership for deeper health and usage analytics.

Litter-Robot EVO Features
The Litter-Robot EVO brings together automatic cleaning, smart connectivity, and thoughtful design details that make daily cat care simpler and more hands-off.
Smart Odor Control
The Litter-Robot EVO automatically sifts out waste after each use, while the tightly sealed drawer and carbon filter reduce litter box odors, keeping your home smelling fresh.
Self-Cleaning
Automatically sifts waste after every use, leaving a fresh bed of litter with no scooping required. The QuietSift® cycle runs quietly enough that skittish cats won't notice — and neither will you.
EasyClean Design
Modular design with easy-to-clean components for a seamless deep-cleaning experience.
Best Suited For
The Litter-Robot EVO fits naturally into a wide range of living situations, from compact city apartments to busy multi-pet homes, delivering automatic, odor-controlled litter management wherever it is placed.
Small Apartments & Compact Living Spaces
The EVO's reduced footprint makes it a practical fit for studios, condos, and tight bathroom corners where a traditional or larger automatic litter box would not work. Its profile is comparable to a standard litter box, so it integrates into everyday living spaces without dominating the room.
One and Two Cat Households
Designed specifically for homes with up to two cats, the EVO handles the sifting and waste containment automatically after every visit, keeping the litter fresh without daily intervention. For single-cat households, the waste drawer can go up to seven days between emptying cycles.
Connected Pet Care & Remote Monitoring
Through the Whisker app, owners can monitor visit history, receive waste drawer alerts, and control cleaning cycles remotely, making it well-suited for busy households or frequent travelers who need visibility into their cat's routines. Optional Whisker+ membership adds weight trends, duration tracking, and extended historical data for a deeper view of pet health over time.
