Operating Instructions
Control Modes
The Ochangqi Self-Cleaning Cat Litter Box offers three primary operating modes:
- Automatic Mode: The system automatically cleans after your cat exits the litter box, following a set delay (default 3 minutes). This mode provides continuous cleaning and protection.
- Manual Mode: Allows you to initiate a cleaning cycle remotely via the mobile application. This is useful for on-demand cleaning or when you are away from home.
- Sleep Mode (Night Mode): From 12 PM to 7 AM, the unit will not perform automatic cleaning to ensure quiet operation during sleep hours. Cleaning can still be initiated manually via the app during this period.

Figure 4: Three Control Modes. This image illustrates the Manual Mode for remote operation, Automatic Mode for continuous cleaning, and Night Mode for quiet operation during specific hours.
APP Remote Control
The litter box can be controlled via the TUYA app, connecting via 2.4GHz or 5G Wi-Fi. This allows for remote control and monitoring.
- Download the App: Search for "HM Pet" in your app store (iOS/Android) or scan the QR code provided in the app connection guide. You can also visit https://www.pgyer.com/QFXz to download.
- Initial Setup:
- Ensure your phone's Wi-Fi and Bluetooth are turned on.
- Do not plug in the power adapter yet. Press and hold the button on the unit, then plug in the power adapter (do not release the button).
- After holding for approximately 2 seconds, you will hear "Di Di Di". Release the button. The device is now in app binding mode.
- Connect to Wi-Fi: In the app, select your Wi-Fi network and enter the password.
- Bind Device: The app will detect the litter box. Bind the device and name it. A successful connection will be confirmed by a ringing sound.

Automatic Cleaning System
The system automatically sifts and deposits waste into the sealed waste bin after your cat uses the litter box. The integrated purifying device releases ozone to neutralize odors after each cleaning cycle.
- One-Click Litter Replace: The app features a "Clearance" or "Empty" function that allows you to empty all old litter from the basin into the waste bin for easy disposal and refilling.
- Quiet Operation: The working state noise is approximately 35dB, and cleaning noise is around 50dB, designed to be quiet enough not to disturb you or your pets.

Maintenance
Waste Bin Management
- The 10L waste collection bin can hold waste for up to two weeks for a single cat. Monitor the waste level via the app.
- When the waste bin is full, slide it out, tie the litter bag, and dispose of it. Replace with a new litter bag.
