The distance from the nozzles to the surface that is being cleaned will depend on the angle at which the unit is held. In most cases that will be between 2 and 3 inches. This unit could be used to clean a tennis court, however, make sure that the pressure on the washer is not turned up too high as it may be possible to peel or strip the coating from the court. It is always best to test the pressure in an area away from the main playing surface.
