4. Operating Instructions
The UML0 S3P offers intuitive controls and versatile cleaning modes:
- Power On/Off: Press the power button on the handle to start the vacuum. Press it again to turn off.

- Brush Head Operation: The V-shaped anti-tangle roller brush is designed to lift dirt and pet hair while minimizing entanglement. The brush head rotates 90° vertically and 165° horizontally, allowing easy access under furniture. Four built-in LED lights illuminate hidden dust.
- Handheld Conversion: Detach the extension tube and brush head to convert the unit into a handheld vacuum. Attach the 2-in-1 dusting brush or crevice tool for cleaning upholstery, car interiors, or tight spaces.

5. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your vacuum cleaner:
- Emptying the Dust Cup: The large capacity dust cup can be emptied with a single button push. Empty it regularly to maintain suction power.
- Cleaning the HEPA Filter: The 6-stage high-efficiency filtration system includes a HEPA filter. For optimal performance, clean the HEPA filter every 2-3 weeks. It is recommended to replace the HEPA filter every 3 months, depending on usage frequency.
- Cleaning the Roller Brush: Periodically remove the roller brush from the brush head and clean any tangled hair or debris. The cleaning gadget can assist with this.

6. Troubleshooting
If you encounter issues with your vacuum cleaner, refer to the following common solutions:
- No Power: Ensure the battery is fully charged and correctly installed. Check if the power button is pressed firmly.
- Weak Suction: Empty the dust cup if it is full. Clean or replace the HEPA filter. Check the extension tube and brush head for any blockages.
- Brush Head Not Rotating: Check for tangled hair or debris obstructing the roller brush. Ensure the brush head is securely attached to the extension tube.
- Short Battery Life: Ensure the battery is fully charged using the original adapter. Operating in Strong Mode will consume battery faster than Eco Mode.
