3. Product Features

Compact Design: The Deerma 124-660-205 features a sleek, ergonomic design for comfortable handling and effective cleaning.

Powerful Suction: Equipped with a high-efficiency DC motor, this vacuum delivers strong suction to deeply remove dust mites and allergens from fabric surfaces.

UV-C Germicidal Lamp: Utilizes a honeycomb UV ultraviolet light with a wavelength of 253.7nm for effective sterilization and mite removal, achieving up to 99.9% removal rate. Features an anti-leak design and automatic shut-off when lifted.

HEPA Filtration System: The 0.3mm HEPA filter captures most dust mites, allergens, hair, and dander, ensuring clean air exhaust. The filter net is washable for easy maintenance.
- High-Frequency Tapping: Features a vibration mechanism that taps surfaces to dislodge deeply embedded dust mites and dirt, facilitating their removal by suction.
- Hot Air Dehumidification: Synchronous hot air exhaust system helps to dry the cleaned surface, reducing humidity in mattresses and inhibiting the reproduction of dust mites.
- Two-Speed Operation: Allows selection of appropriate suction power based on cleaning needs.
- Infrared Sensing Protection: Automatically deactivates the UV-C lamp when the device is lifted from the surface, ensuring user safety.
4. Setup

- Cleaning Surfaces: Gently glide the vacuum cleaner over the surface to be cleaned (e.g., mattress, sofa, carpet). Ensure the base of the vacuum makes full contact with the surface for effective UV-C sterilization and tapping action.
- Targeted Cleaning: For heavily soiled areas or deep cleaning, move the vacuum slowly and methodically.
