You hook both the air and the water to it and then turn the taps on, gives an amazing blast of water that quickly dislodges dirt from the bottom and sides of the car. Even without the air on the water jet is pretty strong!!
Comes with a straight and under body nozzles for getting in hard to reach places. Underbody nozzle could do with being a bit longer though.
Well worth getting hold of to get under the car to wash that salty sand off!!
