Reach and wash type window cleaning, and water usage.
How much water do I need for a days window cleaning, and
how fast should I have the water coming out the brush??
This question seems to be the most read posting on the
water fed pole board on the window cleaning forum. The
answer is a hard one, and I usually tell prospective
customers who ask, "it depends on how fast a worker you
are". A slow worker on a fast water flow will waste quite a
bit of water over the day, whereas a fast worker on a slow
water flow will waste a lot of time in the day, as he will
be waiting around for the window to have enough water
passed over it to wash the window properly.

I have seen on numerous occasions while observing window
cleaners using a water fed pole while window cleaning,
using far too much water on a single window. People seem
to brush the glass then rinse far too much, far more than
is necessary for a perfect finish. When I see or hear of
people using too much water I usually tell them to clean
the windows as normal preferably on a building they are
going to be cleaning the insides as well. I tell them to
clean a couple of windows spending half the time and using
half the water, then thoroughly check all the windows while
cleaning the insides. They are usually very surprised with
the results, with no difference between the windows they
have cleaned normally, and the ones they used half the
time, and half the water on.

It also depends on what type of windows you will be
cleaning, domestic or commercial. Domestic uses less water
as the pole is being heightened and lowered more than in
commercial. Another thing that will determine water usage
is the type of jets you use, fan spays will use less water
than pencil jets as they make better use of the watter
spraying water under more pressure to the very edges of the
glass. Last but not least is the way you turn the water on
and off while working. If you have to keep stopping what
your doing to turn the water off between windows you will
tend to keep the water running between windows, this tends
to waste a lot of water in the day.

Its only when you get into the swing of things and find out
what settings are best for you, will you find out how much
water you personally will need for your days work

I developed a system for stopping the water easily at the
brush to save such water, it can be seen at
