Six months with an $899 AI litter box: the scooping works, the AI does not

Whisker's $899 Litter-Robot 5 Pro, the top of the company's four-model line, sat in a Verge reviewer's home for six months, and the verdict is that the mechanical part works and the computational part does not ^[1][2][7][9]. For anyone deciding whether a vision model bolted to a physical product is a capability or a price tier, that is a rare piece of long-run evidence.

The pitch is a dual camera system plus a sensor array, described in terms of AI algorithms and machine learning, that will monitor and track a cat's bathroom habits rather than just clean up after them ^[3]. Two named features failed in ways that are hard to reframe. WasteID, which is meant to tell urine from feces and cycle the drum faster on the latter to cut odor, repeatedly misidentified waste, according to the review ^[4]. The two cameras could not tell a large gray and white tabby from a small, sleek tuxedo cat, confusing the two and eventually merging them into two identical cats ^[5]. Size and coat color are the easy end of the discrimination problem.

The recurring revenue sits on top of that: Whisker Plus at $8 a month, covering the AI health features and video storage, or $96 a year ^[6][15]. Over six months it delivered not one actionable or useful insight, the reviewer writes ^[6]. One caveat the review supplies itself is that the cat stayed healthy throughout, so there was no event to catch ^[17]. What remains demonstrated is failure at cat identity and waste classification, which are the inputs any health inference would be built on.

The tidy version of this story is that the AI carries a $300 premium, the gap between the 5 Pro and the $599 Litter-Robot Evo ^[2][13]. The material does not support that cleanly. The Evo is a different machine: no litter-level monitoring, support for fewer and smaller cats, a smaller bin, no night light, no compatibility with the litter hopper accessory ^[10], and the reviewer found its build less sturdy with a finicky waste drawer that does not always shut ^[11]. Against the $699 Litter-Robot 4 the gap narrows to $200 ^[14], and even there the reviewer credits the 5 Pro with a bigger bin, more intuitive controls including an LCD screen, and a larger dome, none of which are software ^[8]. The comparison that would actually isolate the price of the AI is the 5 Pro against the plain Litter-Robot 5, and that price is not in the review ^[16].

One more design decision is worth logging, because it shows where the cameras are pointed and why. The front-facing camera records visits, but the interior cameras offer live view only, so the owner cannot retrieve footage of the event the health features claim to interpret ^[12]. Whisker sells a camera mount accessory for the older Litter-Robot 4 precisely so owners can watch ^[12].

Watch whether the recognition failures are fixed over the air or quietly stay in the spec sheet, and whether Whisker Plus keeps charging for health features that a six-month test says produce nothing.
