The first windows were cleaned by servants or housewives with a bucket of water, a ladder, and a rag. By the end of 19th century the first modern skyscraper was built. With the grown in taller buildings came the growth in higher windows, and the need for a professional window cleaning industry. Later on a cleaning trade group was developed in Berlin by Marius Moussy. His former employees also started their own businesses in other cities, and they founded additional cleaning institutes. Until 1953 it was called the glass and building cleaning industry. As the new window cleaning industry began to grow, so did the need for window cleaning tools. At the present time you find several different methods of window cleaning such is traditional, mobile elevated platforms, abseiling or water fed poles. We use the reach and wash system with water fed poles or the traditional method.
