Xiaomi Smart Dehumidifier - 20L

The Xiaomi Smart Dehumidifier 20L has been designed for powerful and intelligent humidity control throughout the home. Up to 20L of moisture per day can be removed under specified conditions, helping excess humidity, damp air, mould-prone environments, and moisture around stored belongings to be managed more effectively. With its compact white design and hidden universal wheels, the smart dehumidifier can easily be moved between bedrooms, bathrooms, storage rooms, children’s rooms, and other indoor spaces.

Quiet and automated operation has also been prioritized. Noise can be reduced to as low as 35.8dB(A) in Sleep Mode, while five noise-reduction designs are used to minimize vibration and operating sound. Indoor temperature and humidity can be continuously monitored by built-in precision sensors, while humidity levels can be adjusted between 40% and 70% through the Mi Home/Xiaomi Home app. Remote app control, Google Assistant and Amazon Alexa voice control, clothes-drying functionality, a large 4.5L water tank, and external continuous drainage are also supported for convenient everyday use.

Key Features

20L Daily Dehumidifying Capacity

Powerful moisture removal is provided with a dehumidification capacity of up to 20L per day at 30°C/80% RH. Excess moisture can be efficiently extracted from indoor air, making the unit suitable for different areas throughout the home.

Panasonic Dual-Rotor Compressor

A Panasonic dual-rotor compressor is used to provide powerful dehumidification with reduced vibration. Smooth operation and improved noise control are achieved through the symmetrical dual-rotor configuration, while high energy efficiency is supported.

Efficient Twin-Curve Design

Dehumidifying efficiency is improved through an efficient twin-curve design. A larger contact area is provided within a compact structure, allowing moisture to be removed effectively without requiring a large appliance footprint.

Five Noise-Reduction Designs

Quiet performance is supported through five dedicated noise-reduction features. A vertical ventilation design, variable-speed DC brushless motor, compressor vibration reduction, dual-rotor compressor structure, and noise-reducing water tank design are combined to reduce operational sound and vibration.

Quiet Sleep Mode

Noise can be reduced to as low as 35.8dB(A) when Sleep Mode is activated. Output is automatically reduced for quieter nighttime dehumidification, allowing excess moisture to be controlled with minimal disturbance.

Smart Humidity Monitoring

Indoor conditions are monitored using built-in precision temperature and humidity sensors. Humidity can be automatically adjusted according to the selected settings, while variable humidity control from 40% to 70% can be configured through the Mi Home/Xiaomi Home app.

Three Operating Modes

Different indoor requirements can be handled through three operating modes:

• Smart Mode: Humidity is automatically adjusted to maintain a comfortable indoor environment.
• Clothes Drying Mode: Continuous airflow and dehumidification are used to help clothing dry more quickly.
• Sleep Mode: Operating noise is reduced for quieter nighttime use.

Clothes Drying Function

Air is discharged vertically from the top of the unit so that circulation can be increased around clothing. Continuous dehumidification is used to accelerate moisture evaporation while clothing is dried gently and evenly.

4.5L Large Water Tank

A 4.5L water tank is included and has been designed to support extended operation. Under Xiaomi's specified test conditions, up to eight hours of continuous dehumidification can be provided. When the tank becomes full, operation is automatically stopped to help prevent overflowing or leakage.

External Continuous Drainage

Continuous drainage can be enabled through the included drainage pipe. Collected water can be directed straight to a drain, allowing 24/7 dehumidification to be used without repeatedly emptying the water tank.

Digital Display and Touch Controls

Indoor humidity information can be clearly viewed through the large digital display and indicator lights. Operating modes and target humidity settings can be selected directly through the touch-control panel.

Humidity status can be indicated as:

• Dry: Below 40% relative humidity
• Comfortable: 40%–70% relative humidity
• Humid: Above 70% relative humidity

Mi Home / Xiaomi Home App Control

Remote dehumidifier management can be provided through the Mi Home/Xiaomi Home app. Operation can be controlled remotely, while timers can be configured for delayed starts, extended finishes, and preset dehumidification schedules.

Google Assistant and Amazon Alexa Voice Control

Hands-free control can be provided through compatible Google Assistant and Amazon Alexa smart voice devices. Integration with compatible Xiaomi smart devices can also be configured through the Mi Home/Xiaomi Home ecosystem.

Compact and Minimalist Design

A simple white exterior has been used so the dehumidifier can be integrated into different home interiors. Its compact footprint has been designed to fit within approximately the area of an A4 sheet of paper, allowing it to be positioned conveniently in smaller spaces.

Hidden Universal Wheels

Hidden universal wheels have been integrated into the base so the dehumidifier can easily be moved between rooms without affecting its clean exterior design.

Reusable Dust Filter

A removable dust filter has been included and can be cleaned and reused, helping regular maintenance to be kept simple.

Child Lock

A child-lock function has been included so unintended operation by children can be prevented.

Tip-Over Auto Shutdown

Automatic shutdown can be activated if the unit is tipped over, providing an additional operational safety feature.
