Fan Jets or Pencils Jets Water Fed Pole

That is the question Jarvis Clean discussed with Thomas at CleanRight. Is one better than the other? Which jet do you prefer for your water fed pole? Can you draw with a fan and cool yourself with a pencil? Does it really matter which jet you have for your brush? We take a honest look at fan jets and pencil jets for cold pure water fed pole systems and review them after using them in our window cleaning work in Surrey and London.

Fan jets or pencil jets (what’s the difference?)

Fan Jets Water Fed Pole

A pencil jet for water fed pole is normally a 2mm hole but you can get different sizes and has been the go to jet for a brush head water fed pole system for window cleaners for many years. Fan jets are becoming more and more popular with window cleaners and they come with a choice of spray angle (mainly 50’ or 100’). Gardiner now sell a multipack of pencil jets and fan jets, jet capsules.
​ ( https://gardinerpolesystems.co.uk/jet-capsules-quick-release-jets-for-brushes.html )which shows us that window cleaners want options and different glass and window frames might need a different jet of pure water. Also in windy conditions the fan jet will easily be pushed around by the wind so when your rinsing it will not spread water evenly on the glass, the pencil jet will be better in windy conditions to clean the glass. As the volume of water, the water flow will be higher, helping to penetrate through the wind and rinse the glass.

Why is there a need for a fan jet?

It is important for a water fed pole window cleaner to be efficient and fast. You want a good brush and water jets that will saturate the brush fully to help remove the dirt off the glass and then rinse well, covering the largest area of glass possible, creating a “waterfall effect” with the pure water rinse. There are advantages to a fan jet to achieve these goals over pencil jets. Nothing wrong with pencil jets but there are always ways to improve our methods of window cleaning and equipment, even as small as the water jets.

Fan jets durability (better than pencil jets)

The fan jets seem to be made out of a plastic and the pencil jets a brass. The brass pencil jets would last longer where the fan jets will brake easier and will need replacement from time to time so having a box of spares will be handy.

Does the fan jet consume more water?

From our experience of window cleaning in Surrey all day, you do use more pure water than the pencil jets. Water consumption is higher with fan jets but if it makes you more efficient... you will be making more money quicker and saving time overall. In terms of water consumption, the difference between pencil jet and fan jets is pretty small.

Fan jets or pencil jets - conclusion

It is really down to personal preference, but here are some things to consider.

We want to be as efficient as possible when using the water fed pole system

Water consumption

Durability - will it last?

Even on a small component for water fed pole cleaning. It is important to think about the details and do as much research as possible to help you with your window cleaning.


Creating the “waterfall effect” will help you rinse more efficiently and save time and lower your water consumption. Some glass and frames are different, for example some glass are hydrophobic (repelling the pure water) preventing you from creating the “waterfall effect”. Holding the brush close to the glass with the fan jets will help you to create the “waterfall effect”.


Having a selection of fan jets and pencil jets is something that we are going to do here at Jarvis Clean in Surrey UK and I know Thomas at Clean Right already has a selection.
