Angle to the cleaning surface
When spraying water against a surface, maximum impact
is generated when the water strikes the surface “head
on.”
However, this type of impact tends to cause dirt particles
to imbed in the surface, thereby preventing the desired
cleaning action. The optimum angle for spraying water
against a cleaning surface if 45 degrees.
Spraying water against a surface at this angle provides
for the most beneficial impact force combined with
efficient removal of debris from the surface.
