use a high level of pure water. If pure
water flows over a surface, it absorbs all existing substances,
like dust, dirt etc. and leaves a smear free
surface, after thorough flushing and sufficient drying time.
Pure water does not leave any residue unlike most
window cleaning methods. No need to wipe the contaminates
pure water is pumped through a hose reel, up a telescopic
Water Fed Pole and through jets in the brush where it is
sprayed onto the glass. When the brush contacts with the
surface of the glass and frames, it lightly agitates the
surface, loosening the dirt. Any dirt or dust particles
are flushed away by the constant stream of water.
