The self-cleaning litter box is arguably the biggest innovation in pet tech of the past decade. What cat owner wouldn’t want a machine that handles the most unpleasant chore of pet ownership? The whirring globe rotates after your cat leaves, sifting clumps into a hidden drawer, so you only have to empty the waste bin once a week. For people who travel or have busy schedules, it’s a game-changer. But as the products evolve, manufacturers are adding more intelligence to the mix, and that’s where things get complicated.
The Hardware and the Promise
Whisker, the company that popularized the automatic litter box with the Litter-Robot series, has now released the Litter-Robot 5 Pro. Priced at $899, it’s the company’s most advanced model, featuring a dual-camera system, a suite of sensors, and AI-powered features that promise to recognize individual cats and monitor their bathroom habits. The goal is to give pet owners actionable health insights, such as early signs of kidney disease or diabetes, which often manifest through changes in litter box behavior. It’s an ambitious idea that could genuinely improve the lives of cats and their owners.
The Litter-Robot 5 Pro is a great pooper-scooper wrapped in AI that just doesn’t work. The hardware is genuinely impressive. The globe is larger than previous models, making it comfortable for bigger cats, and the LCD screen provides clear feedback about the machine’s status. The app is also well-designed, offering remote control of most features, including the ability to cycle the litter box on demand. The built-in scale can measure each cat’s weight as they enter, which is useful for monitoring weight changes.
Testing with Two Cats
I spent six months testing the Litter-Robot 5 Pro alongside two other models from Whisker: the $599 Litter-Robot Evo and the $699 Litter-Robot 4. My household includes two cats — Smokey, a large gray and white tabby weighing about 13 pounds, and Boone, a small, sleek tuxedo cat roughly two years younger. They are very different in appearance, which makes the AI’s failure to tell them apart even more baffling.
Both cats took to the robot immediately. Smokey jumped in and did his business right away; Boone followed shortly after. The machine is remarkably quiet, and the sealed waste drawer effectively contains odors. In terms of basic functionality, the Litter-Robot 5 Pro does exactly what it should. The only complaint on the mechanical side was that Boone, the younger cat, enjoyed playing with the cycling globe, occasionally batting at the interior and triggering the obstruction sensor. He also shredded the optional litter mat within a week.
Cat ID and Facial Recognition
The most anticipated feature of the 5 Pro is Cat ID, which uses a front-facing camera to recognize individual cats and assign each waste deposit to the correct feline. Whisker calls this system PawPrint. After about a week of use, the app prompts you to set up PawPrint, using images the camera has captured of your cats. The system picks what it thinks are the best images, but in my case, they were all blurry or poorly lit. You cannot upload your own photos, nor can you retake them.
The initial setup doomed the entire experience. The camera confused Smokey and Boone repeatedly, and at one point, it merged both cats into identical weight and activity profiles. Smokey’s weight suddenly dropped by two pounds overnight because the robot assigned his visit to Boone’s profile. The system didn’t correct itself, and a week later, both cats were still registering the same weight. Resetting the profiles, reassigning incorrect visits, and correcting video logs took hours. Even after all that, the camera still couldn’t tell the two apart.
Whisker says the system is designed to learn and improve, and that environmental factors like poor lighting and bad initial imaging can throw off recognition. The company also told me it has improved the enrollment process to be more selective about the images used for facial recognition. But for a nearly $1,000 product, the out-of-the-box experience should not require users to wait months for fixes.
WasteID and Scale Issues
Beyond Cat ID, the 5 Pro promises WasteID, a feature that uses sensors to differentiate between urine and feces, allowing the robot to prioritize removing solid waste to reduce odor. It also claims to measure the weight of each deposit, which could help monitor for health issues. In my testing, WasteID consistently failed to identify the type of waste or provide deposit weights.
Whisker diagnosed my unit’s gas sensor as faulty and attempted a remote correction. When that didn’t improve things, they determined that the onboard scale was also off, which may have contributed to both WasteID and PawPrint errors. They offered to replace the entire unit. A robot that needs replacement within a few months of purchase, no matter how good the mechanical scooping is, is a hard sell at this price.
The weight tracking, which is part of the base functionality, also proved unreliable. The scale frequently registered the wrong cat’s weight, and even when it was correct, the numbers didn’t align with reality. At one point, the app reported that Smokey weighed 12.5 pounds, which was less than his actual weight. I joked that I wish my bathroom scale was as generous.
Camera Limitations
The 5 Pro has two cameras: one aimed at the front of the robot to catch cats entering and existing, and another inside the globe to provide a view of the litter box. The advertising implies that both cameras record video clips for owners to review, but that’s not the case. The interior camera offers only a live feed, so unless you happen to catch a cat in the act, you’ll never see what’s happening inside. Whisker says recorded interior footage is coming soon, but it’s not available now.
The front-facing camera does record, and it can be used as a safety feature to check on your pets remotely. However, it has a significant privacy pitfall. I placed the robot in my laundry room, which was across from a powder room. A week later, I realized the camera was capturing not just my cats’ bathroom trips but also anyone entering or leaving the powder room. Whisker offers a setting to record only when a cat is spotted, but cats often accompany their owners to the bathroom, so you might still record unintended footage. It’s a reminder that any smart home device with a camera needs careful placement.
The Subscription and Patterns
The AI features require a subscription called Whisker Plus, which costs $8 per month. It covers the health insights and video storage. In six months, I did not receive a single actionable or useful insight. The company recently rolled out a new feature called Patterns, which summarizes each cat’s daily activities, such as how often they visited the litter box and how much time they spent inside. It also reports weight trends. Patterns is a step in the right direction, but it still lacks waste-type details and relies on the same unreliable weight data.
Subscriptions for premium features are common in smart home products, but it stings when you pay extra for features that don’t work. The fact that Whisker has been improving the software over time is hopeful, but early adopters have effectively paid to beta-test the AI.
Comparison: Evo and Litter-Robot 4
If the 5 Pro is too expensive or too flawed, the rest of Whisker’s lineup offers more sensible options. The Litter-Robot Evo is the budget model at $599, but it makes significant compromises. It lacks litter-level monitoring, so the app won’t alert you when litter is low. It supports fewer and smaller cats, has a smaller waste drawer, and doesn’t work with Whisker’s litter hopper accessory. The build quality also feels less sturdy than the Litter-Robot 4, and the waste drawer is finicky, sometimes not closing properly. The Evo does have an LCD screen, which is a nice touch, but it’s not enough to justify the savings.
The Litter-Robot 4, at $699, is the sweet spot. It doesn’t have AI or cameras, but it includes reliable automatic scooping, weight tracking, and app connectivity. It supports up to four cats and is compatible with the litter hopper. The only downside is the confusing LED indicator lights, which are less intuitive than an LCD screen, but that’s a minor issue compared to the 5 Pro’s dysfunctional AI. I tested the Litter-Robot 4 previously and found it to be excellent.
Which One Should You Buy?
If you’re looking for a self-cleaning litter box and want the best value, the Litter-Robot 4 is still the one to buy. It does everything a cat owner needs without the gimmicks. If you have a large cat or multiple cats (up to five) and want the larger globe, the regular Litter-Robot 5 might be worth considering. It costs $100 less than the Pro version and drops the cameras and facial recognition, though it keeps WasteID. Since WasteID is still unreliable, I would only recommend the 5 if you value the larger capacity.
The Litter-Robot 5 Pro is a fantastic pooper-scooper wrapped in AI that just doesn’t work. Whisker has fallen into a common smart home trap: placing too much faith in AI’s potential rather than its real-world performance. The company says the system is designed to learn and improve, and maybe it will. However, as consumers, we’ve heard too many times that a product will get better with updates. You should never buy a device based on promised future features. Today, the Litter-Robot 5 Pro’s AI is simply not ready.
