2. Product Features
The HMC5 is equipped with advanced features to provide an optimized cleaning experience:
- 4-in-1 Automatic Functions: The device automatically activates Beating, Suction, UV Lamp, and Drying upon startup, penetrating deep into fabrics.
- Integrated Dust Sensor: A smart LED sensor indicates dust levels. It glows red for dirty surfaces and turns green when the area is clean, ensuring thorough cleaning.
- Motorized Agitator: Rotates at 4,200 revolutions per minute to beat the mattress, dislodging dust mites and allergens from deep within the fibers.
- UV-C Lamp: Helps reduce bacteria and maintain hygiene. For safety, the UV light activates only when in direct contact with a surface and deactivates when lifted.
- Drying Function: Utilizes warm air to prevent moisture buildup and inhibit mold growth.
- Dual Container Design: Ensures powerful and sustained suction with a 0.6 L capacity, allowing for complete cleaning without frequent emptying.

3. Setup

- Initial Inspection: Before first use, ensure the dust container and filter are correctly installed.
4. Operating Instructions
4.1 Powering On and Automatic Functions
To begin cleaning, simply press the power button. The HMC5 will automatically activate all four functions: Beating, Suction, UV Lamp, and Drying. There is no need to select individual modes.
4.2 Using the Dust Sensor
The integrated dust sensor provides real-time feedback on surface cleanliness:
- Red Light: Indicates that the surface is dirty and requires further cleaning.
- Green Light: Indicates that the surface is clean.
Move the cleaner slowly over the surface, observing the sensor light to ensure thorough cleaning.
4.3 UV Lamp Operation and Safety
The UV lamp is designed to activate only when the device is in direct contact with a surface. This safety mechanism prevents accidental exposure to UV-C rays. Ensure firm contact with the mattress or fabric for the UV lamp to function. UV-C rays are not visible to the human eye.
4.4 Versatile Application
The HMC5 is suitable for various fabric surfaces, including mattresses, sofas, cushions, and children's mattresses. Its lightweight design makes it easy to maneuver and store.
