Operating Instructions
The PETKIT PuraMax offers flexible cleaning modes and smart monitoring via the PETKIT app.
App Control and Cleaning Modes
The PETKIT app (2.4GHz Wi-Fi enabled) provides comprehensive control and monitoring capabilities:
- Auto-Cleaning Mode: The device automatically cleans after your cat uses it.
- Scheduled-Cleaning Mode: Set specific times for the litter box to clean.

Capacity and Multi-Cat Use
The PuraMax features a large 76L inner cylinder, suitable for cats up to 18 lbs. The 7L waste bin can hold waste for up to 15 days for a single cat, reducing the frequency of waste disposal. Its 7.8-inch low-entry design is accommodating for older cats, short-legged cats, and those with limited mobility.

Maintenance
Litter Compatibility
The PuraMax is compatible with various types of clumping cat litter, including:
- Clay litter
- Tofu litter
- Mixed litter
- Bentonite litter
Note: Crystal cat litter is not compatible with this device.
The unit includes a high-performance non-woven fabric cylinder mat designed to prevent soft feces from sticking. The premium oxford cloth and PVC material are waterproof, preventing urine leakage.
Odor Removal
The PuraMax features a double odor removal system:
- Sealed Waste Bin: The 100% sealed waste bin effectively contains unpleasant odors.
- K3 Air Purifier Smart Spray: This removable odor eliminator automatically deodorizes after cleaning cycles and can be scheduled for deodorization via the app.

Cleaning and Disposal
Regular maintenance is crucial for optimal performance:
- Waste Bin Emptying: The 7L waste bin allows for up to 15 days of hands-free scooping for one cat. Simply remove and dispose of the lined waste bag when full.
- Inner Cylinder Cleaning: The non-woven fabric cylinder mat is designed to be sticky-free. For deeper cleaning, the inner components can be removed and cleaned according to the detailed instructions in the full user manual.
- Low Noise Operation: The device operates at less than 35dB, ensuring it does not disturb your rest.
Troubleshooting
This section addresses common issues you might encounter with your PETKIT PuraMax.
Sensor Interference / Malfunctions
As noted in the setup guide, it is critical to place the PuraMax on a firm, flat surface. Placing the device on carpets or mats can interfere with the internal sensors, leading to:
- Inaccurate weight readings.
- Failure to initiate cleaning cycles.
- Unnecessary pauses during operation.
If you experience these issues, ensure the device is on a hard floor and not blocking the entrance.
Urine Leakage
Some users have reported instances of urine leaking from the inner liner to the underside of the machine. This can occur if urine seeps through the gap between the replaceable liner's plastic edge and the casing, especially with cats that urinate high on the sides. While PETKIT has released updated drums to address this, if you experience this issue:
- Regularly inspect the area beneath the rotating barrel for any moisture.
- Ensure the inner liner is correctly seated and secured.
- Contact PETKIT customer support for potential solutions or updated parts if the issue persists.
