Operating Instructions
The PET MARVEL C1 offers automatic cleaning and smart monitoring features to simplify litter management.
Automatic Cleaning Cycle
The litter box automatically initiates a cleaning cycle after your cat exits the unit. The internal mechanism sifts the litter, separating waste into the sealed waste drawer below. This process is designed to be quiet and efficient.

Smart Safety System
The unit is equipped with a 4-layer smart safety system to protect your pet:
- Infrared Sensors: Detect presence near the entrance.
- Gravity Sensors: Detect the cat's weight inside the litter box.
- Distance Sensors: Monitor the area around the unit.
- Anti-Pinch Sensors: Prevent injury during operation.
These sensors ensure that the cleaning cycle immediately stops if a cat is detected nearby or inside the litter box, resuming only when the area is clear.

APP Health Monitoring
Connect the litter box to the PET MARVEL app via 2.4GHz WiFi to access real-time monitoring features:
- Track your cat’s toilet frequency and duration.
- Monitor litter levels.
- Receive instant alerts for abnormalities, such as a full waste bin or cleaning errors.

Maintenance
Regular maintenance ensures optimal performance and hygiene of your PET MARVEL C1 litter box.
Waste Disposal
The waste drawer utilizes drawstring bags for easy and hygienic disposal. When the app or indicator light signals a full bin, simply pull the drawstrings to seal the bag and remove it for disposal. Replace with a new bag.
Litter Replacement
To replace all litter, use the one-click empty function. This feature tilts the internal bucket to transfer all used litter into the waste drawer, eliminating the need for manual scooping.
Cleaning the Unit
The PET MARVEL C1 is designed for tool-free disassembly, allowing for thorough cleaning. The internal liner is leak-proof, scratch-resistant, and tear-resistant, making it durable and easy to clean with water and a brush.

Troubleshooting
This section addresses common questions and issues you might encounter with your PET MARVEL C1 litter box.

Figure 7: Frequently Asked Questions for the C1 Litter Box.
- Q1: How do I replace the litter in the C1 litter box?
A1: Activate the One-Touch Tilt Litter System. Press the button to tilt the bucket and transfer used litter directly into the waste drawer—no manual scooping required. - Q2: How often should I clean it for two cats? Will odors develop?
A2: The 9L waste drawer holds waste for two cats for up to 10 days. The triple-sealed odor control system (deodorizer + sealed waste bags) prevents daily smells. - Q3: Will cats scratch the interior of the C1?
A3: The C1 litter box is made of very hard-wearing ABS and triple-proof cloth, which has been tested for 10,000+ scratches, so you can rest assured that you will be able to use it. - Q4: Can I use any bag in the waste drawer?
A4: Yes, the waste drawer is compatible with most standard-sized bags. However, we recommend using C1-specific odor-lock bags (Search B0D8G8I6YV) for seamless fit and direct waste contact avoidance.
