Abstract

The present invention discloses a steam floor mop, comprising a handle; a central body inside which a manual water pump, a water tank, and a steam generator are housed; and a floor brush connected flexibly to the central body, wherein the manual water pump, the water tank, and the steam generator are connected to the floor brush by means of pipes; said handle is connected directly to the piston rod of the manual water pump and serves to manipulate the operation of the manual water pump; said floor brush is covered by a cleaning cloth. In accordance with the steam floor mop of the present invention, by only pushing the handle of the steam floor mop, the steam can be generated and distributed to the floor brush so that the cleaning work having an effect of high temperature disinfecting and sterilization can be realized. It is not needed to power on the water pump additionally so as to supply water to the steam generator to generate the steam.
