Usage
Dustbin Assembly Installation
Align the dustbin slot with the protruding part and push the dustbin down until you hear a "click" indicating it is installed.
Powering On/Off
- Connect the mite vacuum cleaner to the power supply and press the On/Off button to turn it on.
- Upon first use, the device defaults to low suction mode.
Note: Hot air will be emitted from the heat dissipation opening during use. A slight odor from the exhaust port during the first use is normal and will disappear after some usage.

- Low Suction Mode: Suitable for daily cleaning of soft textiles like plush toys and quilts.
- Intelligent Mode: Adapts suction power automatically based on mite density for various cleaning scenarios. Higher mite density results in stronger suction.
- High Suction Mode: Suitable for deep cleaning of hard textiles like mattresses and sofas.
Care and Maintenance
General Warning: Always switch off and unplug the mite vacuum cleaner before cleaning or maintenance.
Dustbin Cleaning
Regularly clean the dustbin to prevent dust accumulation, which can lead to blockages and reduced suction power. It is recommended to open the dustbin over a trash can to prevent dust from falling onto the floor. Do not immerse the mite vacuum cleaner in water during cleaning.
Daily Dustbin Cleaning
- Press the dustbin release button and pull out the dustbin assembly.
- Empty the dustbin over a trash can, aligning the marking 'o' with the symbol '6'. Open the dustbin assembly upside down, empty the dustbin, and clean the surface of the dustbin cover assembly.
- After emptying, align the marking 'o' on the dustbin with the symbol '6' to reattach the dustbin cover assembly to the dustbin. Then, twist the dustbin until the marking 'o' aligns with the symbol '8'. You should hear a "click" when it is securely locked.
- Check if the baffle plate of the dustbin assembly is installed correctly. Then, reinsert the dustbin assembly into the main unit.
Washing the Dustbin Assembly
When suction power decreases, clean the dustbin assembly promptly to restore mite removal performance and prevent air duct blockage.
- Remove the dustbin cover and twist it to remove the cyclone separator.
- Remove the filter holder assembly from the dustbin cover, then remove the filter and filter wadding sequentially.
- Clean the surfaces of the dustbin, dustbin cover, cyclone separator, filter holder, filter, and filter wadding. Rinse with clean tap water and allow them to air dry thoroughly.
Notes:
- It is recommended to wash and clean the filter every 5 to 6 uses, or more frequently as needed.
- It is recommended to replace the filter every 2-3 months to ensure optimal suction power.
- Ensure all parts are thoroughly air-dried (away from direct sunlight) after rinsing before reinstallation.
- Reinsert the filter wadding and filter into the filter holder and press them into place. Then, place the filter holder assembly into the dustbin cover and press it into position.
- Align the symbol '8' on the cyclone separator with the marking 'o' on the dustbin cover. Then, twist the cyclone separator until the marking 'o' aligns with the symbol '8'. You should hear a "click" when it is securely locked.
- Securely lock the dustbin and the dustbin cover assembly, and then reinsert the dustbin assembly into the mite vacuum cleaner.
Roller Brush Cleaning
- Activate the roller brush release button as indicated on the mite vacuum cleaner; the roller brush cover will automatically pop open. Remove the roller brush cover.
- Remove the roller brush by pulling it upwards from the right side. Remove any hair and debris from the roller brush. Note: It is recommended to clean the roller brush at least once a month. Rinsing is not recommended.
- Reinstall the roller brush after cleaning. Align the clips on the roller brush cover with the corresponding slots to reattach it, and push it down until you hear a "click".
Cleaning the Inlet and Mite Sensors
Remove the dustbin assembly to access the mite sensors in the inlet. Clean them with a dry cloth or towel.
Notes:
- It is normal for dust and other particles to accumulate in the inlet. Clean it promptly.
- If the mite sensors are dirty, the dust mite density indicator light will blink orange. Clean the mite sensors immediately. Regular cleaning of the sensors helps prevent dust accumulation and ensures detection accuracy.
- The air inlet filter wadding serves as a filter; do not discard it. If the filter wadding becomes dirty, remove and rinse it with clean tap water. Ensure it is thoroughly air-dried (away from direct sunlight) before reinstallation.
