What is cleaning with demineralised water? How does the Water Fed technology work?
The Water Fed technology involves washing the surface with a brush on a telescopic pole with a stream of demineralized water. Demineralized water is completely pure water, free of any minerals. Fully purified water provides fantastic results when washing windows and facades - it reduces static electricity, cleans perfectly without chemicals, does not leave smudges or streaks after evaporation, and the cleaned glazings become exceptionally glassy after washing. The Water Fed technology is used to clean glazings, photovoltaic panels, advertising pylons, blinds, metal structures and smooth facades up to a height of 24 meters or with rope/lift access.
Demineralized water can be obtained in two ways.
There are therefore two types of filter units

Find out all about the Reos ONE system
What is
the Reos ONE system
and how it works?
Several months of design work, hundreds of tested solutions and thousands of ideas allowed us to create Reos ONE - a compact water demineralization system based on the process of reverse osmosis and deionisation. The device was designed with attention to the smallest details, resulting in a product without faults. The system uses a state-of-the-art reverse osmosis membrane and does not require electricity - it is powered by water pressure from the network. You can connect a pole and hoses from any manufacturer to the system using appropriate connectors.
You can increase the efficiency of the system by using a dedicated pump. It allows you to perform jobs in places where the water pressure is very low or the water source is further than 80 m away. The pump will also increase the output of demineralized water, thanks to which two people can use the system simultaneously. In cooperation with the leading pump manufacturer, Grundfos, we have created a product that ensures maximum efficiency, while retaining a compact size. Reos Grundfos is an efficient pump packed in a handy frame allowing for an easier movement with the equipment.
The Reos ONE system employs three-stage water filtration in order to achieve maximum efficiency and reduce operating costs. The first carbon-sediment filter allows retention of chlorine and sediments, including solid particles such as sand grains and pollen. Then the water goes through the reverse osmosis membrane - at this stage Reos purifies the water from ~98% of minerals and contaminations. During the reverse osmosis process, water is divided into two categories - waste, containing minerals and contaminations, and clean water, which then passes through the last deionization filter. Thanks to this solution, we obtain 100% purified water that does not leave streaks or stains after evaporation..
This solution allows for an "easier start" - at the beginning, you can purchase a system without a pump, learn how to clean surfaces, perform assignments within a range of up to 80 m from the water source, and later decide to buy a pump at a moment suitable for you.
It is easier to transport the system in the car - sometimes you will work alone and lifting a standard system, weighing over 40 kg, into a passenger car without scratching the bumper might be quite challenging. Thanks to our solution, you will not encounter this problem.
Why is the pump not integrated into a single frame with the system like in the case of most producers?
You don't always have access to electricity on your assignments. Sometimes it is enough to use only a water source - then the pump may be left in the car.
If your assignment requires carrying the system, our light solution will allow you to do it single-handedly :).
We provide
a 3-year warranty for Reos devices and lifetime after-sales support.
Thanks to its simple design and ease of use, the system is suitable for both experienced professionals and people only beginning their adventure with the Water Fed technology.
The system allows to save a lot of time in comparison to rope access services or cleaning using a lift. Within an hour, a single operator can wash 50-150 m2 of surface!
Compact size and low weight - you can easily provide services, even if you have only a small passenger car at your disposal.
Thanks to its simple design and ease of use, the system is suitable for both experienced professionals and people only beginning their adventure with the Water Fed technology.
Enables work in places such as city centres, pedestrian areas, promenades, patios, roofs, areas surrounding office buildings – any place with an access to running water.
Dozen competitive advantages
of the Reos ONE System
When operating the system, there is no need to use detergents, which helps avoid unaesthetic streaks and stains on the cleaned surfaces.
Quality workmanship and simple design ensure the highest level of failure-free operation.
Practical handles in several places and inflatable pneumatic wheels make transport convenient.
More troublesome dirt is removed mechanically, not chemically, which guarantees neutrality for the natural environment.
Filters and membranes come in the most popular sizes - we did not opt for the rarest and most expensive components in order to keep operating costs at the lowest possible level.
Price – it is extremely competitive so that you can easily set up or grow your business while minimizing costs.
You can buy spare parts from us - if you accidentally damage the system, we provide advice, service and parts at attractive prices.
Demineralized water ensures the highest quality of cleaning. Such water is completely free of contaminations. Regular washing of the surfaces with mineral-free water visibly improves the aesthetics and extends the life span of the construction.

Operating costs and efficiency
The tables provide approximate values for resin/filter consumption in the Reos ONE reverse osmosis system and in the deionization system with a capacity of 11 liters. Values may vary depending on the area where the water source is located. This is due to the variety of substances dissolved in water.
Within an hour, one operator can wash between 50 and 150 m2 of surface.
Differences between a reverse osmosis system and a deionization system you will find here.
The amount od substances in the water can be checked using the TDS meter (total dissolved solids - a sum of dissolved substances). The purity level is given in PPM (part per minion - parts per milion). If the PPM is 0, the water is completely demineralized. Fully purified water provides fantastic results when cleaning windows and facades - reduces electrostaticity, cleans perfectly without chemica
