- Plug the other end of the cable into a compatible 5V 1.5A USB power adapter (not included).
- The charging indicator light at the bottom of the device will illuminate red during charging.
- Once fully charged (approximately 3-3.5 hours), the indicator light will turn green.
2.2 Attaching Nozzles

3. Operating Instructions
3.1 Power On/Off and Mode Selection
- To power on the device, press and hold the power button. The LCD screen will illuminate.
- The device typically starts in low power mode. Press the power button briefly to switch between low (L) and high (H) power modes. The LCD screen will display the current mode and battery level.
- To power off the device, press and hold the power button again until the screen turns off.
3.2 Vacuuming Function
Attach the desired vacuum nozzle (e.g., long flat nozzle for crevices, brush nozzle for surfaces). Turn on the device and select the appropriate power mode. Guide the nozzle over the area to be cleaned. The high-end mode provides 17KPa suction for stubborn dirt, while the low-end mode offers 6KPa for lighter debris and longer battery life.


3.3 Blowing Function (Dust Removal)
Attach the blowing nozzle to the exhaust port of the device. Turn on the device and select the desired power mode. Use the powerful airflow to dislodge dust and debris from hard-to-reach areas, such as car vents, keyboards, or electronic components.

3.4 Inflating Function
Attach the appropriate inflation nozzle to the blowing port. This function can be used for inflating small items like balloons or air cushions. Ensure the item to be inflated is compatible with the nozzle and the device's airflow.

4. Maintenance
4.1 Emptying the Dustbin
Regularly empty the dustbin to maintain optimal suction power. To empty:
- Ensure the device is turned off.
- Twist or unlatch the dustbin from the main unit.
- Carefully remove the filter.
- Empty the collected debris into a waste bin.
- Reassemble the filter and dustbin, ensuring they are securely attached.
4.2 Cleaning the Filter
The filter should be cleaned periodically to prevent clogging and maintain performance. Depending on usage, clean the filter every few uses.
- Remove the filter from the dustbin.
- Tap the filter gently to dislodge loose dust.
- If necessary, rinse the filter under running water. Ensure it is completely dry before reinserting it into the device. Using a damp filter can damage the motor.

8. User Tips
- Pre-charge for optimal performance: Always ensure the device is fully charged before a major cleaning session to maximize suction and runtime.
- Choose the right nozzle: Utilize the various attachments for specific tasks. The brush nozzle is great for carpeted areas or pet hair, while the flat nozzle excels in tight spaces.
- Regular filter cleaning: A clean filter is crucial for maintaining strong suction. Clean it after every few uses, especially when dealing with fine dust.
- Don't overfill the dustbin: Empty the dustbin before it's completely full to prevent loss of suction and strain on the motor.
- Use blowing function creatively: The blowing function is not just for dust; it can also be used to clear debris from hard-to-reach areas before vacuuming, or even to dry small wet spots.
