Reverse Osmosis Window Cleaning – Pure Water Technology for Spotless Cleaning

Reverse osmosis window cleaning is the most innovative and efficient solution for cleaning exterior windows at low to medium heights – without climbing, ladders, or annoying water streaks. With this technology, we use “purified water” that undergoes special filtration – to achieve a sparkling result without using any cleaning agents at all. The method is ideal for businesses, shops, offices, and residential buildings up to 5 floors.


How Does Reverse Osmosis Window Cleaning Work?

The reverse osmosis window cleaning technology is based on advanced water filtration using a reverse osmosis system + activated carbon + DI filter. The resulting water is free of metals, salts, and limescale – and therefore doesn’t leave drying marks on the glass.

Using a special telescopic pole, we feed the water through a soft brush to clean the window. The combination of water pressure, pure water, and controlled contact – washes away the dirt and leaves the windows completely clean.


When is it Recommended to Book Osmosis Window Cleaning?

  • Exterior windows up to 20 meters high

  • Shops, restaurants, and businesses with wide glass fronts
