PETKIT Purobot Max Pro 2 AI-Camera Self Cleaning Cat Litter Box
Owners who want an app-bound camera box and will keep up with its consumables
The Purobot Max Pro 2 is PETKIT's camera-equipped self-cleaning box, model P9904 in the manual. It must be bound to the PETKIT app before first use, lists Scoop, Deodorize, Maintenance and Empty on both the app and the on-device panel, and has two litter sifters matched to mineral or tofu and mixed litter. PETKIT publishes dimensions, weight, a 12V 2A input and a six-month minimum cat age, but no bin volume, entry height or noise figure. Full video playback needs a PETKIT Care+ subscription.

- Two sifters are matched to litter types, and the on-device panel lists every main function alongside the app
Caveats
- It cannot be used at all until it is bound to the PETKIT app, and full video playback needs a PETKIT Care+ subscription

Whisker Litter-Robot 4, White (LR4-0101-00-US)
Households with up to four cats that each weigh at least three pounds, with a firm, level spot that leaves clearance on every side.
Whisker's automatic sifting litter box, 29.5 by 22 by 27 inches and 24 pounds, with a 15.75 inch square entryway, a 14 by 14 inch litter bed, a sealed waste drawer, weight sensing and app reporting of litter and waste levels.
Published specifications
- Assembled size 29.50 in high x 22.00 in wide x 27.00 in deep; weight 24 lb (manual)
- Entryway 15.75 x 15.75 in, 12.00 in from the floor, or 6.90 in to the optional step plus 4.50 in
- Litter bed 14.00 x 14.00 in; inside globe 19.00 x 18.00 in, 15-17 in high depending on litter level
- Waste drawer 5.50 x 13.50 x 9.25 in; takes Whisker liners or any 10-13 gallon (37-49 l) trash bag
- Suits up to 4 cats; each cat must weigh at least 3 lb (1.4 kg) for Automatic Mode
- Optional sealed 12V DC 1.3 Ah backup battery; Wi-Fi and night light are disabled while it runs
Strengths
- The manual publishes the entryway, litter bed, globe interior and waste drawer sizes alongside the assembled size, so each can be checked against your space.
- The manual gives emptying intervals of once a week for one cat and twice a week for two average-sized cats, and liners can be any 10-13 gallon bag.
- An optional backup battery switches in automatically when power is lost, and the app reports litter and waste levels after each use.
Caveats
- The listing prints two sets of dimensions and neither matches the manual's 29.50 by 22.00 by 27.00 inches.
- It must stand clear of walls on a firm, level surface for accurate weight measurement, and Whisker sells a Carpet Tray separately for carpet.
- The 90-day in-home trial is coordinated with whoever sold you the unit, not with Whisker, when the purchase is not direct.
