PETKIT Purobot Ultra Multi-Cat Care Bundle (two units) review

PETKIT’s current U.S. product page calls this the Purobot Ultra Multi-Cat Care Bundle. Its public product record identifies the exact package SKU T6-B_T6-B: two copies of the T6-B Purobot Ultra, whose model number is P9903. This is two separate enclosed machines, not one enlarged box, a shared waste bin, or evidence that PETKIT rates the package for a particular number of cats.

Two stations means two chores and two footprints

Each machine has its own 70-liter rotating chamber, 10-liter bag compartment, camera, control panel and app connection. The bundle does not combine those into a 20-liter drawer or one coordinated cleaning cycle. Plan two firm, level floor locations with at least two inches of wall clearance, a clear approach to each entrance and room to lift out each cylinder. Each box is about 20.94 by 32.20 by 24.09 inches and weighs about 32 pounds before litter. The long footprint makes a pair a substantial room-planning choice, especially if one unit will sit upstairs or in a narrow alcove.

A second box can be useful when a home needs separate stations, such as different floors or rooms. It is not automatically the best answer for a multi-cat household: the listing title says “Multi-Cat,” but PETKIT’s product facts give no rated cat-count capacity for one Ultra or the pair. Its statement that the camera recognizes up to 15 cats describes profiles, not how many cats can safely or comfortably share a cleaning cycle. If a maker-published capacity is an essential filter, this bundle should not pass.

One machine at a time for bag packing

The Ultra’s differentiating waste system seals a filled bag and advances a new bag from a proprietary PETKIT refill ring after you remove the full one. The manual directs the owner to initiate packing at the OLED panel and stay by the unit; after removing the sealed pack, the owner confirms liner refill at the controls. The bundle does not remove that attended step. It simply means there are two machines, two refill rings and two bags to monitor. A second unit does not turn the first machine’s bin estimate into a guarantee, and the published “up to 20 days” figure is PETKIT’s single-adult-cat lab estimate. Empty or pack according to actual usage and check both stations before leaving home.

Camera histories and privacy are per-device decisions

Each P9903 has a swiveling camera and app-based cat profiles, with maker-described stool/clump records, yowling events and optional color-change litter alerts. Those features may help you notice activity, but they do not diagnose illness. The manuals describe camera privacy controls and tie full video playback to PETKIT Care+ terms. Do not assume one account will automatically merge both histories or allocate a visit to the correct machine: the bundle page presents the pair, but it does not spell out a shared-device workflow. Set up and verify each unit separately, including the desired camera schedule and privacy settings. If you prefer no recorded footage, the manual allows camera-off operation while automatic cleaning continues.

Check every cat against the same limits twice

PETKIT’s page lists 3.3 to 22 pounds and the manual prohibits use below six months or 1.5 kg. The manufacturer also says to use a hard, level surface because carpet or soft flooring can disturb the sensors. Each cat has to enter either box through its own opening, about 10.43 inches high; a two-box kit does not provide a lower step. The page supports 2.4- and 5-GHz Wi-Fi, but the manual requires app binding before first use. The camera’s individual profiles and its “15 cats” recognition claim are not capacity guidance.

The machine uses clumping litter and two sifter designs for different granules; keep pieces within the maker’s limit of 12 mm long and 3 mm wide and fill only to the MAX line. Stuck material still means brushing and cleaning. The manual says not to rinse the base, camera or auto-packing module. Two machines therefore double the access and upkeep points: expect two surfaces, two cylinders, two waste bins and two refill rings to service.

Choose the exact two-unit offer only if you need both units

This Double Bundle fits a shopper who already wants two identical Ultra stations and values camera tracking plus sealed-bag packing at both. If one Ultra is enough, the base T6-B is the relevant listing; the single-unit review also explains the Starter Bundle SKU T6-B_T-Litter-2_N60-3_T6-AP-3, which adds three refill rings, three N60 odor eliminators, two bags of PETKIT’s named “Flushable Clumping Cat Litter,” and a stated two-year warranty. Do not select the double package just because “multi-cat” sounds like a capacity guarantee. If you require a published count, the answer remains unknown.

For another PETKIT routine, the Max Pro 2 is one camera-equipped clumping-litter machine with an 8-liter bin and a different drawstring waste method; the Max 3 uses weight-based tracking without a camera. Neither the multi-cat product name nor buying two units establishes a cat rating. The Ultra vs Max Pro 2 comparison explains the two bag routines and camera tradeoffs. Confirm the actual offer and warranty for the units you purchase from PETKIT’s exact Double Bundle page, and read the Purobot Ultra manual for each unit’s installation, litter and cleaning limits.
