PETKIT Purobot Ultra Self-Cleaning Litter Box: features, specs and who it suits

The PETKIT Purobot Ultra (model P9903) is an automatic litter box that cleans itself after each visit, seals the waste in a bag and fits a fresh bag when the bin is full. It also carries a camera that recognises individual cats. It is aimed at households that want less scooping, especially homes with more than one cat.

How the self-cleaning and bagging work

After a cat leaves, the box runs a cleaning cycle and moves the waste into a sealed bin. PETKIT says the unit packs the waste into a bag, seals it and loads a new bag automatically once the bin reaches capacity, so you lift out a closed bag rather than emptying a loose bin. The bin holds 10 litres, and PETKIT rates it at about 20 days without scooping for one cat. The supplied bags are rated at roughly 200 days for one cat visiting twice a day, based on PETKIT's own lab data. Figures like these depend on the number of cats and how often they visit, so treat them as a guide for a single-cat home.

The box works with clumping litter, which is how most automatic boxes separate waste from clean litter. Its interior space is listed at 70 litres.

What the camera does

PETKIT describes a camera that rotates 180° and captures a 210° wide angle. It identifies each cat by face and logs the time and duration of each visit, along with the shape and colour of stools and the size of urine clumps. The app keeps photo and video records for each cat, so in a multi-cat home the entries are kept separate. PETKIT presents this as a way to follow changes in bathroom habits over time. It is a record-keeping tool; questions about a pet's wellbeing belong with a vet.

The camera also supports live viewing and two-way talk through the app.

Safety sensors and cat size

PETKIT says 20 sensors manage the operation, and an X-axis rotation keeps the entrance open. It is recommended for cats aged 6 months and older, weighing between 3.3 lb (1.5 kg) and 22 lb (10 kg). Anyone with a very large cat or a kitten should check that range first.

Odour control and noise

The listing describes four layers: a sealed waste bag, an odour-locking bin, a built-in odour control insert and the automatic packing system. Noise is rated at under 35 dB, which is quieter than a typical conversation, though cleaning cycles will still make some mechanical sound. PETKIT advises against placing the box on soft carpet, because it can interfere with the sensors; a hard board or tile underneath is the suggested fix.

App and Wi-Fi

The unit connects to 5 GHz and 2.4 GHz Wi-Fi and is controlled from a phone app. Many smart devices only join 2.4 GHz networks, so dual-band support can simplify setup on modern routers.

Size and placement

At roughly 20.9 x 26.8 x 32.7 inches (about 53 x 68 x 83 cm) and 46 lb (about 21 kg), it is a large piece of equipment. It needs a hard, level floor, a nearby outlet and enough clear space for the entrance.

Who it suits

It suits owners who are away from home often, multi-cat households that want per-cat records, and anyone who likes app-based monitoring. It is less of a fit for tight spaces or for people who want a simple, no-app litter box.

What to check before you buy

• Space: measure the spot, including height and the clearance for the entrance.
• Your cats: confirm each cat is within the listed weight range and age.
• Wi-Fi: check signal strength where the box will sit.
• Flooring: plan for a hard, flat surface rather than carpet.
• Ongoing supplies: bags and odour inserts are consumables; check how they are supplied.
• What's in the box: read the manual for setup and cleaning steps, and unplug the unit before cleaning.
