AbstractA dust collector having a selector valve which enables a cleaning pipe to be connected with either a suction circuit communicating with a dust collecting portion, or a discharge circuit communicating with the discharge opening of a fan. By carrying out the shifting operation of said selector valve, the dust collector can be changed to suck and collect dust, or to blow and gather dust without rearranging the cleaning pipe.
