A suction brush of a vacuum cleaner for both vacuum cleaning and steam cleaning, comprising:

• a brush main body connected to a cleaner main body;
• a steam generating unit heating water being supplied from a water storage tank mounted on the brush main body and spraying steam generated by heating the water on a surface to be cleaned;
• a turbine fan, installed in the brush main body, generating a rotating force by drawn-in air that flows into the brush main body;
• a power transfer unit driven by the rotating force of the turbine fan;
• and
• at least one pair of duster rotating plates, arranged on a lower part of the brush main body, the least one pair of duster rotating plate being rotated by power being transferred through the power transfer unit;
• wherein each of the at least one pair of duster rotating plates has a part that is detachably attached to the power transfer unit to attach/detach a duster to/from a bottom surface of the duster rotating plate,
• wherein the steam generating unit comprises a micro-pump connected to the water storage tank, the micro-pump pumping the water stored in the water storage tank and a heater unit for steaming the water being supplied from the micro-pump by instantaneously heating the water and spraying the steam on the surface to be cleaned through a spray nozzle, and
• wherein the heater unit comprises an upper case having an inflow tube formed thereon to receive the water being supplied from the micro-pump and a lower case detachably coupled to the upper case and having a heater that is arranged under an instantaneous heating region of the heater unit to heat the water.
