The "Water Fed Pole" cleaning method is becoming a standard tool amongst window cleaners, especially since the 2005 WAHR were introduced restricting the use of ladders in the workplace.
The "water fed pole" system utilises highly purified & de-ionised water which is pumped up a telescopic pole to a specially designed brush. The brush is used to agitate any dirt/dust on your windows & frames, and the pure water rinses away the dirt to give a sparkling shine. Because the water is free from dissolved minerals, the glass dries naturally free from spots & streaks that would occour with tap water.
At JD's window cleaning we are proficient in the use of both "water fed pole" cleaning and traditional methods - but we only use ladders where no other option is practical.
