The PETKIT Pura Max 2 is an upgraded self-cleaning cat litter box designed for multi-cat households, featuring a 76L interior capacity and a 7L waste bin that can hold up to 15 days of waste for one cat. It improves upon the original model with an enhanced 360° sealed cylinder and a “ShieldBase” to prevent leaks, particularly for cats that urinate on the side walls.
Core Features.

xSecure Safety System: Employs 11 high-precision sensors, including infrared, weight, and proximity sensors, to immediately pause the cleaning cycle if a cat approaches or enters.
Triple Odor Control: Combines a sealed waste bin, an N50 2.0 odor eliminator that neutralizes ammonia, and a K3 Air Purifier Smart Spray that deodorizes the chamber after use.
Universal Litter Compatibility: Works with 99% of clumping litters (tofu, bentonite, clay, or mixed) and includes two different sifters for fine or coarse particles.
Whisper-Quiet Operation: Operates at a noise level under 35 dB, which is quieter than a whisper and suitable for night use.
App and Health Tracking.

Smart Monitoring: The PETKIT App identifies individual cats by weight and tracks toilet frequency, duration, and behavioral patterns to help detect potential health issues.
Cleaning Modes: Offers three modes via the app: automatic (cleans after each use), scheduled, and manual.
Remote Alerts: Sends real-time notifications to your smartphone when your cat uses the box or when the waste bin is full.
