High-Pressure Cleaners help Save Water and Cleaning Agent use. A world without high-pressure cleaners is inconceivable in many trades, in the painting and decorating trade, in agriculture or the automotive trade. Many home and garden owners would not want to be without their high-pressure cleaner either, because there is nothing as fast or thorough as a high-pressure cleaner for cleaning your vehicle, removing moss from patios, algae from swimming pools or dirt from facades. Furthermore, these machines are not only useful; they are environmentally friendly, too.
There are two reasons for this claim: First, high-pressure cleaners reduce water consumption. The restricted bore cross section (the nozzle), which is required to increase pressure, reduces the water flow volume. Compared to a garden hose, for example, this achieves a water saving of up to 80%, assuming the average suburban household pressure of about 4.5 bar, about 3,500 litres of water flow through the hose every hour, while the flow rate through the spray lance of a high-pressure cleaner is only 400 to 600 litres in the same time. In addition, the actual time spent on the cleaning job is cut drastically and this, in turn, reduces water consumption even further.
