The special tip nozzle rotates at high speeds to spray air vibrations. Traps out sand, dust, etc. that get into the carpet, etc. Unlike regular air guns, the air will come out at a high speed swirl from the tip. It is easy to remove dust from gaps such as grooves, and can also be quickly removed from the drainer. Can be used for a wide range of applications. Pulse air spray with a special nozzle allows for powerful dust removal and draining. By rotating the nozzle at high speed, it produces pulse air with vibration. The pulse air with vibration has a peeling effect, so the pulse air can enter deep into dirt and water such as grooves, crevices, and dimples can be removed cleanly.
