Operating Instructions
The YOWMOFT Cat Water Fountain offers three distinct watering modes to suit your pet's needs and conserve energy.
- Sensing Water Outlet (Motion Sensor Mode):
When the motion sensor detects movement from a living body, the fountain will discharge water continuously. If no movement is detected for 2 minutes, the water flow will stop. This mode conserves power and ensures fresh water when needed. - Regular Water Discharge (Timed Mode):
In this mode, the fountain will discharge water for 2 minutes every hour. This provides periodic hydration without constant flow. - Continuous Water Discharge:
The water will flow continuously in this mode, providing a constant stream of fresh water.
To switch between modes, refer to the control panel on the fountain. The UV light operates internally to purify the water and may not be visibly illuminated from the exterior.

Maintenance
Regular maintenance ensures the longevity and hygienic operation of your YOWMOFT Cat Water Fountain.
- Daily Water Check: Ensure the water level is sufficient. Refill as needed.
- Weekly Cleaning (Inner Tank): The double-wall inner design allows for easy cleaning. Simply lift out the inner tank, empty any remaining water, and wash it with mild soap and water. Rinse thoroughly to remove all soap residue.
- Monthly Cleaning (Entire Unit): Disassemble the fountain completely. Clean the pump according to its specific instructions (usually involves disassembling and cleaning the impeller). Clean the main body and all other components.
- Filter Replacement: Replace the filter every 2-4 weeks, or more frequently if you have multiple pets or notice reduced water flow/quality. Rinse new filters before installation.
- UV Light Maintenance: The UV light is designed for long-term use. If you suspect an issue, refer to the troubleshooting section or contact customer support.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Fountain not turning on | No power, low battery, or power button not pressed. | Ensure Type-C cable is securely connected or battery is charged. Press the power button. |
| No water flow or weak flow | Low water level, clogged filter, dirty pump, or incorrect mode. | Refill water. Replace filter. Clean pump. Check selected watering mode. |
| Fountain is noisy | Low water level, dirty pump, or improper assembly. | Ensure water level is adequate. Clean the pump and impeller. Reassemble components correctly. |
| UV light not visible | UV light operates internally. | The UV light is designed for internal water purification and may not emit visible light from the exterior. This is normal operation. Ensure the fountain is powered. |
