The invention discloses a sole scrubbing machine, belongs to the field of scrubbing and is intended to solve the problem of energy consumption of an existing cleaning machine. According to the technical main points, one surface, opposite to the bottom, of a parallel plate is provided with a track; a slide block sliding along the track is arranged on the track; the slide block is hinged with a semicircular inner tooth plate; the inner tooth plate is coupled to a vertical plate; the slide block slides to push the inner tooth plate to move in the vertical direction along the tangential direction of a connection point; a fan-shaped inner gear ring is arranged on the inner tooth plate; a gear is meshed with the inner gear ring; the gear is connected with a horizontal transmission shaft; a driving bevel gear connected with the horizontal transmission shaft and a driven bevel gear connected with one end of a vertical center transmission shaft form bevel gear transmission; and the other end of the vertical center transmission shaft penetrates through the parallel plate and a work plate and is connected with a center hairbrush arranged on the work plate. The sole scrubbing machine has the effects that a person directly stands at a designated position on the product, the gear is driven to rotate along with descending of the working surface of the product, and a wheel brush is driven to rotate through a series of gear transmission, thereby completing sole cleaning.
