PETKIT PuraMax 2 Automatic Litter Box: features, specs and who it suits

The PETKIT PuraMax 2 (model P9902) is an automatic, self-cleaning litter box that runs a cleaning cycle after each use and moves waste into a sealed bin. It is built for homes with one or more cats and is controlled from a phone app.

How the automatic cleaning works

The litter sits in a rotating cylinder. After a cat leaves, the box separates the clumps and drops them into the waste bin. Four cleaning modes are listed: auto, manual, timer and empty. You choose them in the app instead of on a control panel. The waste bin holds 7 litres, which PETKIT rates at up to 15 days of automatic scooping, depending on the number of cats. The box works with most clumping litters.

Weight-based cat recognition

Rather than using a camera, the PuraMax 2 identifies cats by weight. The app records each cat's weight, how often it visits and how long it stays. That makes it useful for keeping an eye on routines in a multi-cat home, with the caveat that cats of similar weight can be hard to tell apart by this method. The unit connects over 2.4 GHz Wi-Fi.

Interior size and low entry

The interior is listed at 76 litres, and the box suits cats between 3.3 and 22 lb (about 1.5-10 kg). PETKIT says it should not be used for animals under 6 months. The entry step is 7.87 inches (about 20 cm), which the brand describes as friendly to older cats, short-legged cats and cats with limited mobility.

Sensors and safety features

Seven infrared sensors and four weight sensors detect a cat inside or approaching. PETKIT says the box pauses when a cat comes near, and an anti-pinch structure keeps the entrance open. As with any automatic appliance, read the manual and watch how a new cat reacts to it in the first days.

Leak protection and odour control

A seamless "ShieldBase" is described as sealing the cylinder through 360°, aimed at keeping litter and liquid from getting into the mechanism. The litter pad has elastic edges and a waterproof, non-stick, scratch-resistant surface, to make wiping easier. For odour, the sealed waste bin works with an N50 2.0 odour remover. PETKIT notes that this version is not compatible with the K3 Smart Spray.

What's included

The basic bundle lists the litter box, an N50 2.0 odour remover, 20 waste bags, a litter sifter, a magnetic litter remover, decorative stickers, a quick start guide, the manual and a US adapter. The accessories are packed inside the waste bin. Coverage of two years is mentioned in the product name.

Size and placement

It measures about 24.2 x 22.0 x 22.0 inches (61 x 56 x 56 cm) and weighs 22 lb (10 kg). PETKIT says to put it on a flat floor, not on carpet or mats, which can disturb the sensors, and not to block the entrance.

Who it suits

It suits multi-cat homes, owners who want app-based records and a lower entry for older cats, and people who like a lighter unit than the largest camera models. It does not include a camera, so it is a better match for those who want simple data rather than video.

What to check before you buy

• Cat size and age: within 3.3-22 lb and at least 6 months.
• Wi-Fi: the app needs a 2.4 GHz connection.
• Floor and space: a flat, hard surface and clear access to the entrance.
• Accessories: this version doesn't work with the K3 Smart Spray.
• Upkeep: bags and odour remover are consumables, and the cylinder and pad need regular cleaning per the manual.
