The present invention relates to a suction device, including a body. A cavity is disposed in the body. The cavity has a closed end face and an open end face. The open end face forms an end face to suck a workpiece. A tangential nozzle is disposed on a sidewall surface of the cavity. An external fluid enters the cavity through the tangential nozzle along a tangential direction of the cavity. A suction hole is disposed on the closed end face. The suction hole is connected to a suction unit. The suction unit sucks the fluid in the cavity through the suction hole. The suction device can suck a workpiece by using both a rotational flow negative pressure and a negative suction pressure of a fluid in the cavity, and therefore can suppress impact of a workpiece surface on a suction force and generate a larger suction force.
