Achieving Crystal Clear Windows With Cannins: The Magic of Water-Fed Pure Water Systems 

Cleaning windows can be a tedious and time-consuming task, especially when dealing with hard-to-reach areas or stubborn dirt and grime. However, thanks to advancements in technology, the introduction of water-fed pure water systems has revolutionised the window cleaning industry. Here at Cannins we have a van mounted system that produces both hot and cold pure water cleaning to achieve sparkling clean windows effortlessly. 

What is a Water Fed Pure Water System? 

A water-fed pure water system is a cleaning method that utilises purified water that we produce at our commercial units in Wickhamford. Some of our vans are also capable of producing water on demand to clean windows without the need for traditional cleaning agents. The systems we use are from Varitech systems and consist of a telescopic pole, a brush head, and a water filtration and delivery unit. The water is purified through a series of filters and resin, removing impurities and minerals, resulting in pure water that leaves no residue or streaks on the glass once clean.  

Benefits of Using a Water-Fed Pure Water System 

1. Chemical-Free Cleaning: One of the most significant advantages of using a water-fed pure water system is the elimination of chemical cleaning agents. Traditional window cleaning products often contain harmful chemicals that can be hazardous to both the environment and the cleaner’s health. With a water-fed system, you can achieve spotless windows using only pure water, making it an eco-friendly and safe option. 

2. Enhanced Safety: Cleaning windows on high-rise buildings or difficult-to-reach areas can be dangerous. Water-fed pure water systems eliminate the need for ladders or scaffolding, reducing the risk of accidents and injuries to our team.  

The telescopic pole allows our team of cleaners to reach windows up to several stories high from the safety of the ground, ensuring a secure and efficient cleaning process. 

3. Streak-Free Results: The pure water used in these systems has a unique ability to attract and dissolve dirt particles, leaving no residue or streaks behind. Here at Cannins Ltd we give a 24-hour after-clean guarantee for any clean we carry out, giving you customer satisfaction in our company.  

Techniques used by Cannins Operators when Cleaning Windows with a Water-Fed Pure Water System: 

1. Preparing the Equipment: Every day our team start by checking the water TDS on our filtration system to make sure it’s 0.00 TDS (total dissolved solids). They will then decant the water into their van system.  

2. On Location: Once at a customer property they connect the hose and pole to a water delivery system and water tank, then adjust the water flow to achieve the desired pressure. 

3. Wetting the window: The team begin by wetting the window, frame and sills thoroughly using the brush head attached to the pole. The pure water will loosen and dissolve any dirt or grime on the surface. 

4. Agitating the Dirt: They then gently scrub the glass, frames and sills using the brush head, paying extra attention to corners and edges. The soft bristles of the brush will dislodge any stubborn dirt particles, allowing the pure water to rinse them away. 

5. Rinsing: Once the dirt has been agitated, they will rinse the window thoroughly with the pure water. The purified water will attract and carry away the loosened dirt, leaving the frames and glass clean and spotless. 

6. Drying: As the pure water dries naturally, it will evaporate without leaving any streaks or residue. The team will not use towels or squeegees to remove the water droplets, as it may reintroduce impurities or cause streaking. 

What pure water cleaning can’t remove 

While water-fed pure water systems are highly effective at removing most natural types of dirt and grime from windows, there are certain types of stubborn stains or contaminants that may require additional cleaning methods. For instance, pure water systems may struggle to remove heavy mineral deposits, such as hard water stains or lime scale buildup. Additionally, oily or greasy substances, paint, cement and plaster may require the use of specialised cleaning agents to break down and remove the residue effectively. In such cases, please speak to the office or one of our window cleaners before your clean. We will then assess the situation and discuss using the appropriate techniques to tackle these specific types of dirt and contamination.  


Water-fed pure water systems have transformed the window cleaning industry, offering a safer, more efficient, and environmentally friendly alternative to traditional methods. By harnessing the power of purified water, Cannins can provide streak-free results while eliminating the need for harmful chemicals.
