Function Description

The Midea Cube Dehumidifier is designed to remove moisture from the air in indoor residential applications. It can operate in various modes including Set mode (runs until a set humidity is reached), Max mode (continuous operation on high fan), and Continuous run mode (continuous operation with adjustable fan speed). The unit can collect water in a removable bucket or drain continuously via an attached hose. Some models also feature a pump draining option for vertical drainage. The dehumidifier is equipped with an Auto Defrost function to prevent frost buildup on coils and an Auto-Restart function to resume operation with previous settings after a power interruption. It also offers smart control capabilities via a mobile app.
