If scooping is the chore you’d most like to delete from your week, the Purobot Max 3 Automatic Cat Litter Box is designed to reduce the amount of daily scooping. It’s PETKIT’s third-generation self-cleaning litter box, listed at $399.99 in the supplied product information (regularly $499.99), and it’s designed for cats in its specified 3.3-to-22-pound weight range. If you want fresh litter without the daily routine, this one belongs on your shortlist.
We’ve previously covered PETKIT’s AutoSeal waste-disposal system and the brand’s smart pet-care lineup.
What It Is
The Purobot Max 3 is a fully automatic, app-connected litter box that rotates to sift and seal waste after each visit. It uses a 76L cylinder paired with a 7L side waste bin, which is enough to go up to 15 days hands-free in a single-cat home.
What sets it apart from older automated boxes is the extra-wide, low 8.03-inch entry that’s easier on senior cats and kittens alike, plus a four-part odor system that tackles smell instead of just masking it.
It works with 99 percent of clumping litters, including clay, tofu, corn, and bentonite, and ships with two interchangeable sifters so you’re not locked into one litter type.
Cleaning, Safety, and Monitoring Features
OdorVoid Defense System. This is the headline act. A four-layer approach covers the full waste cycle: smart waste covering helps clumps set, a sealed side bin snaps shut behind each clump, the N50 module neutralizes up to 98 percent of ammonia at the source, and the N60 adds on-demand air purification inside the cylinder. The result is a litter box that stays quiet on the nose even days into a cycle.
xSecure Safety System. Twelve sensors track movement and weight in real time, stopping the cylinder when a cat is detected entering and restarting only once they’re clear. Just as reassuring is the anti-pinch structure: the cylinder’s gear is intentionally incomplete, leaving a permanent opening so your cat can always back out, even with no power and no sensors active.
360° ShieldBase Leak-Guard. Leaks at the edges are a common complaint with automatic boxes, and PETKIT addresses that with a sealed cylinder base and a newly engineered 2X anti-stick pad. The denser, more water-repellent weave is built to stay non-stick wash after wash.
Multi-Cat Health Tracking. Through the PETKIT app, the box identifies each cat by weight and tracks visits, patterns, and frequency by name. In a multi-cat home, that data may help owners notice changes worth discussing with a veterinarian; it is not a medical diagnostic system.
Whisper-Quiet Operation. Rated at 35dB, it runs quietly enough to sit in a closet or bedroom without becoming a nuisance, which matters for cats that spook easily and owners who don’t want a motor cycling through the night.
Low-Maintenance Upkeep. One-click litter emptying pairs with the magnetic litter remover to dump old litter automatically, and a maintenance mode tilts the cylinder upward so you can pour a fresh bag straight in without the awkward back-bending. A top control panel handles Instant Clean, odor control, litter leveling, and Wi-Fi setup for anyone who’d rather not open the app every time.
Who It’s For
The Purobot Max 3 makes the most sense for busy owners and multi-cat households who are tired of daily scooping and want to reclaim that time. The low entry suits kittens six months and older, senior cats, and anyone with mobility concerns, while the broad 3.3-to-22 lb weight range covers most cats comfortably. It’s also a strong pick if you travel often and rely on a sitter, since hands-free operation and app alerts mean the box largely takes care of itself. Worth noting: for accurate weight sensing and the smoothest safety performance, you’ll want to place it on a hard, level surface rather than carpet.
