The most successful and frequently used method of the commercial window cleaning industry is the water fed pole method that offers safe access to high-level windows. A water fed pole uses a very high level of purified water which is also used to explain the lab-grade water used by commercial window cleaners.

To use this method successfully, the water should be purified. Ordinary tap water will not do the trick since pure water has the power to absorb all existing substances on a window surface such as dust and dirt residue, leaving a smudge free window. The purifying of the water is carried out through a process known as reverse osmosis. Osmosis is a special case of diffusion (the movement of molecules from an area of higher concentration to an area of lower concentration) in which the molecules are water and the concentration incline happens across a semi permeable membrane. Reverse osmosis which is used in the water fed pole cleaning system happens when the water is moved across the membrane against the concentration incline from lower to a higher concentration level.

Using water fed pole system for office window cleaning purposes as well as high-rise apartments eradicates health as well as safety concerns of workers that are usually involved in the use of ladders. The water fed pole system can be safely operated by one window cleaner from the ground level of any building. This is ranked as the safest window cleaning method for exterior windows in the UK.

There are a number of advantages of the water fed pole system that you can consider. These can reach windows that are located above sensitive ground areas such as flower beds and even lawns and reach many inaccessible areas that were previously out of reach. There are some water fed poles that can reach up to 72ft without leaving the ground and it guarantees the safety of the window cleaner and also reduces the disturbance to any office staff or occupants of the properties that are being cleaned. Greenhouse roofs and windows above them can be cleaned safely from the ground without the agony of using ladders. Window frames and ledges are much cleaner while no damage can be caused in return since there won’t be any sort of heavy ladders leaning against them.
