PURPOSE: A brush adaptation device of a duct cleaning robot is provided to prevent a brush from being damaged or being worn out and to clean by touching a duct in a fixed pressure. CONSTITUTION: A brush adaptation device of a duct cleaning robot comprises a body, a fixed frame(104), and a brush unit(100). The fixed frame is installed between a pair of brush units, and a pressurization measuring unit(200) is installed in upper part of the end of the fixed frame. The pressurization measuring unit comprises a fixing unit, an operation unit, a presser unit, and a sensor unit. The sensor unit comprises a sensor guide(242) and a magnetic linear sensor(244). Pressure, which is generated when a duct surface and the brush unit are connected, is measured so that the brush unit rises when the pressure is lower than predetermined pressure. When the pressure is higher than the predetermined pressure, the brush unit is lowered in order to increase contact power with the duct surface.
