Water-fed pole window cleaning: up high without a ladder, but never under power lines

You offer cleaning of windows, shop fronts, glass façades, conservatories and solar panels with pure-water technology. Tap water passes through a filter with reverse osmosis and ion-exchange resin, loses its minerals and dries without spots. It runs through a hose to a brush at the end of a telescopic pole that reaches upper floors from the ground. In the UK this is a common way to clean windows because it removes ladder work. In Central Europe the method is still less widespread. Your customers are mainly businesses: shops with windows, office buildings, car showrooms, schools, surgeries and owners of solar panels. The catch is threefold. Hard water exhausts the resin quickly, so without reverse osmosis or careful pricing you lose money. A carbon pole conducts electricity and touching or even approaching an overhead line can kill. And you can’t work in frost, because water freezes on the glass and the pavement.
