The cleaning brush is installed on the rotation mechanism and rotates together with the door leaves in a synchronous mode. A bristle brush is arranged on the cleaning brush and the tail end of the bristle brush penetrates through the ground net. The door hood is fixed to the door frame and the door hood is cylindrical and provided with two notches corresponding to the door leaves. The rotation plate is provided with a rotation shaft. The supporting frame is fixed to the door frame and located on the top of the door hood. The driving device is installed on the supporting frame and in drive connection with the rotation shaft of the rotation plate. The door leaves are two in number and arc. The top sides of the door leaves are fixedly connected with the edge of the rotation plate. The rotation door is used for driving the underground cleaning brush to rotate through the door leaves, and the soles of shoes are simply and conveniently cleaned as a person stamps on the ground net.
