The roller brush comprises: a roller brush main body, a slit being formed on the roller brush main body, the slit extending in the axial direction of the roller brush main body, and an outer surface of the roller brush main body matching with the slit to form an opening; a blade assembly, which is provided with cutting teeth for cutting hair wound around the roller brush, the blade assembly being arranged in the slit, and the cutting teeth extending out of the opening and protruding out from the outer surface of the roller brush main body; protective teeth, which protrude out from the outer surface of the roller brush main body, so as to protect the blade assembly; the slit has two sides extending in the axial direction of the roller brush main body; and the protective teeth are only arranged on one side of the slit, and are arranged at intervals in the axial direction of the roller brush main body. By means of the protective teeth protrusion out from the outer surface of the roller brush main body is realized, so as to protect the blade assembly; and the effects of preventing the blade assembly from being damaged or from damaging other objects due to being exposed are achieved.
