As a pet technology writer here on the WIRED Reviews team, I have a lot of opinions on the subject Automatic litter box You must get it. I’ve tested about 20 models, but I keep going back to one of the first models my cat ever used, which is… Garbage robot 4. Of all the brands I tested, Whisker’s connected phone app stands above the rest. The app’s design is clean and easy to use and understand, gives you the ability to monitor usage and control settings while you’re away, and keeps you in touch with your cat’s important health metrics.
In the fall of 2025, Litter-Robot released an all-new line of upgrades Automatic garbage binsAnd we’ve all tested them. of technological progress Garbage Robot 5 Pro With dual cameras and AI-powered insights for small and compact cameras Trash Robot EVOThere’s a Litter-Robot model for every home and budget.

Garbage Robot 5 Pro
This is the Litter-Robot model to choose if you’re a helicopter pet parent like me, have concerns about your pet’s health, or just want the most luxurious model on the market. It has dual AI cameras that capture activity outside and inside the litter box. The new AI technology can recognize up to five cats to determine which ones used the box and when, and WasteID technology to determine what type of visit your cat has had based on weight – Litter-Robot is the only brand on the market with this capability. If you decide to use this model and you have multiple cats, I recommend starting with this model Sharp+ Paid subscription plan ($80 per year) to unlock this feature and enable the system to differentiate between them reliably and continuously.
The connected app also charts trends over time to help you better understand your cats’ health and habits, so you know if anything is wrong (a valuable tool for monitoring your cats’ health). Using WasteID technology, the 5 Pro automatically adjusts odor control based on waste type, instantly cycles solid waste and waits longer after urinating to ensure it is completely clumped for more effective cleaning. The tray is also airtight and larger than previous Litter-Robot models, with up to 10 days of waste storage per cat so you can empty it less often.
Along with the new compact camera, the LR 5 Pro uses a more modern touchscreen instead of physical buttons for manual control; Wider and shallower drawer than previous models; And a longer, removable lip at the entrance. With AI-powered recognition to monitor multiple cats, a camera to monitor their habits, and WasteID technology to identify types of visits and adjust cleaning, the 5 Pro is an invaluable tool for tracking pet health right from your phone.
Best for most people (and cats)
The Litter-Robot 5 is the latest release for my beloved Garbage robot 4Now with WasteID to identify types of waste based on weight (if you have one). Whisker+ subscription), easy assembly and waste removal, and a new LCD control panel instead of buttons. Instead of using an AI-enabled camera like the 5 Pro model above (because it doesn’t have one), this machine identifies which cat is using the box using the built-in scale. The Model 5 works for up to five cats and can store waste for 10 days for one cat, and the connected app provides insight into the cats’ usage habits and weight changes. It also has a slightly larger internal ball bearing area than the LR 4. Plus, when you order directly from Whisker, you get a 90-day in-home trial, a one-year warranty, free shipping, and HSA/FSA eligibility.
