Water fed poling is a relatively new way of cleaning windows and solar panels. So how is done? The water pole consists of a telescopic pole with a soft brush on the end. A plastic tube goes up the middle of the pole and that feeds water to the brush. Older water poles were made of aluminium, these were relatively heavy and used tap water. The new poles are made of fibreglass, carbon fibre or a combination of both. These new poles are very light and easy-to-use, they can be used for long periods without tiring.
In conjunction with these new poles pure water is used. What is pure water? We put normal tap water through a reverse osmosis water purifier that is located on the service vehicle the result is pure water. All the impurities are removed and this allows a spot free finish on solar panels, windows, cars whatever the use might be. The impurities are generally measured as total dissolved solids, TDS, this can be measured with a TDS metre. It is measured in parts per million. 0 ppm is the optimum but anything under 10ppm is okay for a spot free finish. Gold Coast water has about 70 ppm total dissolved solids which is fairly low compared with some places but a long way from 0 ppm.
There are several benefits to using a water fed pole. These poles are able to go up 3 or 4 levels no problem at all, this can bring big savings compared to using special access equipment. Special access equipment for a day, delivered and picked up can be around $500 a day. Safety is another huge benefit, difficult to access windows on sloping or uneven ground can be accessed far more safely with a water fed pole than with a ladder. Another advantage is that the window frames are cleaned thoroughly as well.
