What went wrong with the Litter-Robot 5 Pro's AI features?

The facial recognition system (called Cat ID) failed to tell two different-looking cats apart and eventually merged them into identical profiles in the app. The WasteID system, which was supposed to distinguish between urine and feces, repeatedly failed to accurately identify waste type. The onboard scale also malfunctioned, assigning one cat's weight to the other—the reviewer's 13.4-pound cat Smokey lost 2 pounds overnight when the robot mistook him for his younger brother Boone.

What does the $8/month Whisker Plus subscription cover?

The subscription includes AI health features and video storage. However, during the test, it did not deliver actionable insights, and several core features (like the Patterns summary showing daily visits, weight, and time spent) were rolled out several months after the product launched—meaning owners paid for features that did not work at release.

How much does the Litter-Robot 5 Pro cost, and what are the alternative models?

The Litter-Robot 5 Pro costs $899. Whisker also offers the Litter-Robot 5 ($699, without camera), the Litter-Robot 4 ($699), and the Litter-Robot Evo ($599, smallest and most compact but with fewer features). The reviewer suggests the regular Litter-Robot 5 ($699) is better value than the Pro if you do not need the camera.

Whisker's $899 litter robot can't tell two cats apart

3 Key Points

What happened
The Litter-Robot 5 Pro, Whisker's premium model launched late last year, promises AI-powered cat facial recognition and health monitoring via a $8/month subscription, but after six months of testing, the system consistently failed to distinguish between two differently-looking cats, incorrectly assigned weight readings, and struggled to identify waste type.
Why it matters
For cat owners considering a $899 device specifically for its AI health-monitoring claims, the core promise — early detection of health issues through accurate tracking — does not yet work; false data (like wrong weight assignments) can lead to false conclusions, and the reviewer had to manually correct visits and profiles to help the machine do its job.
What to watch
Whisker says the facial recognition system is built to learn and should improve over time, and the company has rolled out a new Patterns feature (summarizing each cat's daily visits and weight) several months after launch—but 5 Pro owners have been paying $8/month for features that did not work at release; the non-AI Litter-Robot 5 ($699) or LR4 ($699) may be better value.
