The Two Different Methods Of Window Cleaning- Traditional & Waterfed

Why Pure Water?

Tap water contains a thing called “dissolved solids”, which are minerals, metals and salts found in the water. These dissolved solids are fine in drinking water, but not so much when the aim is spot free window cleaning. You’ve probably tried to wash your own windows in the past with a garden hose, it initially looks okay but when the water evaporates, the glass is left spotty as the dissolved solids still remain on the glass. Pure water has no dissolved solids in it whatsoever as its passed through a sediment and resin filter to ensure that no spot causing solids remain. Pure water is not only used in the window cleaning industry, its also used extensively in car washes to deliver that spot free finish we all love.

Use Cases-Traditional

The traditional method is always used to clean internal windows as the waterfed method works by spraying pure water from the brush head onto the glass, something which isn’t a good idea to use indoors! Traditional is normally used on post construction window cleans as you need to get “nose to glass” to remove stubborn debris such as concrete over spray and sticker residue.

Use Cases- Water fed

The main benefit of water fed over traditional is the ability to reach high or awkward windows from the ground. Staying off ladders and roofs as much as practically possible is a priority for a professional window cleaner as falls from even 1 meter can be fatal. The water fed pole telescopes out to many meters, some poles can reach up to 21 meters! Water fed is also well suited to solar panel cleaning due to its reach and also its chemical free cleaning power.

There is more than one way to skin a cat when it comes to cleaning a window professionally. The first method is called “traditional” and the second method is referred to as “water fed”. In this post we will explore the differences between the two methods and also when a professional will utilize one method over another.

Traditional Window Cleaning

Traditional Window Cleaning Method

Traditional window cleaning is all about cleaning a window the way its been done for over 100 years. The method gets its name from the use of traditional tools. These tools are a Squeegee and an applicator. The applicator is soaked in a window cleaning solution and used to wash the window. The Squeegee is then used to remove the solution off the window leaving a clean pane of glass.

Water fed Window Cleaning

Water Fed Window Cleaning Method

The water fed method utilizes a two stage filtration system which takes tap water and turns it into pure or de-ionized water. The pure water is then transported through a thin hose, up a telescoping pole and into a brush head which sprays the water onto the glass. The brush bristles agitate the dirt on the window and the pure water essentially drags the dirt off the glass. The window is then given a final rinse with the pure water to leave a spot free finish.


In conclusion traditional and water fed window cleaning are the two different methods a professional will use to clean windows. Each method has its own strengths and weaknesses which make them excel in different situations. A window cleaner that can utilize both of the methods will be able to work more safely and efficiently than a window cleaner that only uses one method.
