Operating Instructions
Automatic Self-Cleaning
The Purobot Ultra offers two methods for initiating automatic scooping:
- Control Panel: Press the menu button on the device to switch to "scoop", then press the "OK" button to execute the cleaning cycle.
- PETKIT App: On the device's homepage within the app, tap "scoop" and then "OK".
It is recommended to set the automatic cleaning to start 2-5 minutes after your cat uses the litter box. This allows the litter to form solid clumps effectively, preventing it from sticking to the bottom of the tray.
AI Camera and Health Monitoring
The integrated AI camera provides advanced monitoring capabilities:
- Facial Recognition: Accurately tracks individual cat visits, preventing mixed data in multi-cat households.
- Poop Monitor: Records toilet times, duration, stool shape/color, and urine clump size. Generates photo/video records for per-cat health tracking.
- Real-time Alerts: The app notifies you of abnormal stool color or clumping size, aiding in early detection of potential health issues.

Key Features
Touch-Free Auto Waste Packing
The Purobot Ultra automates waste management. After each cleaning cycle, the system auto-fills, seals, and refills the waste bag, eliminating the need for manual scooping and handling. The 10L capacity waste container can hold waste for up to 20 days for one cat, and the included waste bag ring lasts up to 200 days. Overflow protection ensures efficient packing.

Efficient 4-Stage Odor Control
The device employs a quadruple deodorization system to maintain a fresh environment:
- Sealed Trunk Lid: Keeps odors contained within the waste bin.
- N60 Pet Odor Eliminator: Purifies unpleasant smells with a refreshing scent.
- Auto-Sealed Waste Bin Door: Closes automatically after each cycle, sealing in odors with up to 97.5% efficiency.
- Leak-Proof Trash Bag: Made of durable PE material to prevent leaks and odor escape.

XSECURE Safety System
Equipped with 20 high-precision sensors, the Purobot Ultra ensures maximum safety. The cylinder immediately stops operation upon pet proximity, and its anti-pinch structure prevents cats from getting stuck. The cylinder's side-to-side rotation keeps the entrance open at all times. It is suitable for cats weighing 1.5 kg (3.3 lbs) to 10 kg (22 lbs) and over 6 months old.
Upgraded Leak-Proof Design
The cylinder features a 360-degree sealed ShieldBase for anti-leakage and easier maintenance. A patented brim structure guides urine to the waterproof litter pad, preventing leakage. The elastic edge of the litter pad ensures easy installation and a secure fit.
Large Space and Quiet Operation
The 70L interior space provides a comfortable environment for your cat. The Purobot Ultra is compatible with all clumping cat litter types and operates at a noise level of less than 35 dB, equivalent to a quiet library, ensuring a peaceful home environment.
Maintenance
Waste Bag Replacement
When the waste bin is full, the device will automatically seal the bag. Simply remove the sealed bag and dispose of it. The system will then automatically refill a new bag from the refill ring. Ensure you use original PETKIT refill rings to prevent malfunctions.
Cleaning the Unit
The Purobot Ultra features a detachable design for easy cleaning. The 360-degree sealed ShieldBase and waterproof litter pad simplify maintenance. Regularly clean the interior and exterior surfaces with a damp cloth. Avoid using harsh chemicals or abrasive cleaners.
