The latest Ball Cleaning Gun with 4 special blades. 

These 4 special blades are designed on the body of the BALL to generate a stream of airflow when the BALL rotates at high speed, which can prevent foreign objects from entering the Rotatable Set. The stream of airflow generated by the high-speed rotation of the BALL is able to generate a frictional force on the inner wall of the Nozzle, make the BALL reduce the speed, and then generate more torque, so that this cleaning gun can enhance the cleaning power.
