PETKIT PuraMax 2 Odor-Free Automatic Self-Cleaning Cat Litter Box with 2-Year Coverage, W…

The PETKIT PuraMax 2 is an automatic self-cleaning cat litter box designed to take routine scooping out of the daily routine. According to the manufacturer, it combines a 76L interior, app-based control and a dual odor-control system in a white ABS plastic body measuring roughly 24.2 x 22 x 22 inches and weighing about 22 pounds. It ships as a basic bundle with the PuraMax 2 unit, an N50 2.0 odor remover, a roll of 20 trash bags, a litter sifter, a magnetic litter remover, decorative stickers, a quick start guide and a US adapter. PETKIT notes that the accessories are packed inside the waste bin, so the bin should be pulled out on arrival to find them.

Automatic Cleaning and Multiple Modes

Per the specs, the PuraMax 2 cleans automatically after each use in whichever mode is selected. Four modes are available: auto, manual, timer and empty, and all are set through the PETKIT smart app rather than a complex on-device panel. The 7L waste bin is rated for up to 15 days of automatic scooping, which the manufacturer frames as convenient for busy owners or short trips away. The unit is listed as compatible with all kinds of clumping litter.

Dual Odor Control and Leak-Free Design

Odor management relies on two elements: a sealed waste bin and the included N50 2.0 odor remover. Together they form the manufacturer’s odor-control system intended to reduce smells around the box. The upgraded cylinder uses a patented seamless ShieldBase for 360-degree sealing, which PETKIT says helps keep the cylinder odor-free and reduces how often deep cleaning is needed. The high-performance litter pad Max has elastic edges for a tight fit and is described as waterproof, non-stick and scratch-resistant, so urine around the edges should not leak through. One compatibility note from the manufacturer: this version is not compatible with the K3 Smart Spray.

Smart App and Health Tracking

The litter box connects over 2.4GHz Wi-Fi to the PETKIT smart app, where owners can check working status, review usage data and change cleaning modes remotely. According to the manufacturer, the box identifies cats by weight and records each cat’s weight, toilet frequency and duration in the app. Over time, those records are intended to give owners more insight into a pet’s health and help spot irregular patterns. This per-cat data is a notable feature for households with more than one cat.

Safety Sensors and Anti-Pinch Entrance

PETKIT states that the PuraMax 2 is equipped with 7 infrared sensors and 4 weight sensors that detect activity inside or near the box. When a cat approaches the detection area, the unit pauses cleaning to protect the cat. The anti-pinch structure keeps the entrance open at all times, which the manufacturer says helps prevent a cat from getting stuck. These design points matter because the box moves on its own, and the sensors are the main safeguard described in the product data.

Size, Access and Multi-Cat Use

The 76L interior is intended for cats weighing between 3.3 and 22 pounds, and PETKIT advises against use for young pets under 6 months. The 7.87-inch low-entry design is described as friendly to older cats, short-legged cats and cats with limited mobility. Combined with the automatic cycle after each use, the manufacturer positions the box as suitable for multi-cat homes. Two placement notes come from PETKIT: do not put the device on carpets or mats, as this may interfere with the sensors, and do not block the entrance to the litter tray. The unit is backed by a 2-year warranty.

Who is it for

The PuraMax 2 suits owners who want scooping handled automatically and who are comfortable managing settings through a smartphone app. Multi-cat households may benefit from the per-cat weight and usage tracking, and the low entry makes it a reasonable option for older or less mobile cats within the stated weight range. It is less suited to homes with kittens under 6 months, and owners should plan for a flat, hard floor placement rather than carpet.

What owners say

At the time of writing, the PuraMax 2 holds a 4.2 average across 2,714 ratings. The breakdown is heavily positive: 1,900 five-star ratings and 299 four-star ratings make up the large majority, which suggests most buyers are satisfied overall. A smaller group is less convinced, with 163 three-star, 81 two-star and 271 one-star ratings. In short, the rating profile points to strong general satisfaction alongside a meaningful minority who were unhappy, so reading individual reviews before buying is worthwhile.
