A suction nozzle device (11) connected to a vacuum cleaner for cleaning beddings such as blanket. The suction nozzle device includes a nozzle which is coupled through a suction passage (22) to an electric blower of the vacuum cleaner and which has a suction opening (15a) at its end portion which is arranged so as to face an object to be cleaned. Also included a pair of rotatable rollers (16) each of which is cylindrically shaped and has on its outer circumferential surface a plurality of tooth-portions (19,20,21) which are radially protruded from said outer circumferential surface. The suction opening thereof is positioned to be interposed between the pair of rotatable rollers. Each of tooth-portions is elongated by a predetermined length in directions of the axes of the rotatable rollers. Each of the rotatable rollers is divided into a plurality of sections each of which has a predetermined number of the tooth-portions and is formed so as to have at least flat portion between the tooth-portions. The adjacent ones of the plurality of sections are disposed so that their flat portions are in 180 DEG out-of-phase relation to each other.
