Whisker’s Litter-Robot name has become synonymous with the automatic litter box. We’ve tested the entire lineup and can help you choose the best model for your household.As a pet tech writer for the Reviews team at WIired, I’ve had the opportunity to test nearly 20 models of automatic litter boxes. Despite the variety, I find myself consistently returning to one of the first models my cats ever used – the Litter-Robot 4. Among all the brands I’ve tested, Whisker’s connected phone app stands out as the best. The app’s design is clean, intuitive, and allows you to monitor usage and control settings remotely. It also keeps you connected to your cat’s important health metrics.
In the fall of 2025, Litter-Robot released a new line of upgraded automatic litter boxes. We’ve tested them all, from the technologically advanced Litter-Robot 5 Pro with dual cameras and AI-powered insights, to the pared-down, compact Litter-Robot EVO. There’s a Litter-Robot model for every home and budget. All models are available in black or white, though if you’re keeping the litter box in an enclosed area, note that black will show litter dust.
After years of testing, we’ve gathered our thoughts on the Litter-Robot automatic litter box models. If you’re looking for a model with all the bells and whistles, the Whisker Litter-Robot 5 Pro is the one to choose. Priced at $899, this is the model for you if you’re a helicopter pet parent like me, have concerns about your pet’s health, or simply want the most luxurious model on the market.
The Litter-Robot 5 Pro is equipped with dual AI-enabled cameras that capture activity both outside and inside the litter box. The new AI technology can recognize up to five cats to determine which one has used the box when, and WasteID technology to determine what type of visit your cat had based on weight. Litter-Robot is the only brand on the market with this capability. If you have multiple cats, I recommend opting for the Whisker+ paid subscription plan ($80/year) to unlock this feature and enable the system to reliably and consistently differentiate among them.
The connected app also charts trends over time to help you better understand your cats’ health and habits. This is a valuable tool for keeping tabs on your cats’ health. Using the WasteID technology, the 5 Pro automatically adjusts odor control based on the type of waste, cycling immediately for solid waste and waiting longer after urination to ensure it clumps completely for a more effective clean. The drawer is also more tightly sealed and larger than previous Litter-Robot models, with up to 10 days of waste storage per cat so you can empty less frequently.
Along with the new built-in camera, the LR 5 Pro employs a more contemporary touchscreen rather than physical buttons for manual control. It also features a wider, shallower drawer than previous models. This model is the epitome of luxury and convenience for pet parents, offering a comprehensive solution to managing your cat’s waste.
In conclusion, the Whisker Litter-Robot 5 Pro is the ultimate choice for pet parents who want the best for their feline friends. Its advanced features and user-friendly design make it a standout in the market. Whether you’re concerned about your pet’s health or simply want the most luxurious model available, the Litter-Robot 5 Pro is worth considering.
