I've noticed that with a fan jet it fans the whole brush where as the pencil jets jet straight out of the brush. So with this thought in mind is it still ok to rinse with a fan jet. The reason why I ask is wouldnt the fan jet just throw dirt back onto the window as it spraying the whole brush unlike the pencil jet?

Cheers

normally the bristles are cut away in the center of the brush, or you have an overhead fan spray. I have not had any problems, the fan jets really spray a mist over the windows, and rinse quite well.

today i used pencil jets on a shorter pole, where i could actually see how it rinsed, i couldnt really see 45ft high.... but i dont think there as good as fan jets.. the pencil jets only spray two bits of the window and the water spreads as it hits the glass. On the fan jets the mist goes all over the windows and rinses much better in my opinion.

fan jets for me

Do the fan jets use more water than pencil jets. I tried using fan jets in a vikan rectangular brush today. I thought I used more water than normal but it's too early too tell. What's your views?

I would be interested in knowing this too as I am boing to be getting a new pole soon and havent decided on fans of jets.

i was using two 2mm pencil jets and it looked as though they were using much more water, even with 2mm jets the jet of water looked quite thick and was spraying out fast. With the fans they have to go through a thinner slit gap to spray, but some places you have choice of fan jets like cleantech do high or low pressure fan jets, the low ones would use less water i think.

we've fan jets on 2 poles, I used both of them today all day (was on me own today) and got through a full 650tank.

normally 500ltrs would do me but was definitely faster and made more money than normal

I found fan jets used more water,.. and my feet got very wet!

Try aiming the brush at the windows, not your feet, or stand further back, lol

I'm inclined to agree with you. Since I've been trying out fan jets I notice some of my jobs are quicker and I seem to go through the water quicker too.

How long is a piece of string springs to mind.  It depends on how big the holes are in both the fan, and pencil jets.  If the pencil jets have no restriction and the water is flowing freely, then a fan jet under pressure will use less water.  Fan jets also allow the water to spread evenly over the width on the brush.

I don`t mean the ones you sell Peter but some you can get are rubbish they don`t fan hardly at all.

I totally agree with all you have said Peter, however I am using more water than normal with wide fan jets (because they cover more area using less water in theory) and I am definitely quicker (only a bit). I can't explain it but the results speak for themselves. I also like using the fan jets because it sounds like the windows are being cleaned with a small pressure washer attached to the WFP as it's quite noisy and unusual to the peace and quiet of using 2 or 3mm pencil jets. It's still early days comparing the difference between pencil jets and wide spray fan jets for me though so I may be wrong for now, time will tell.

It can depend on what system you have, like you need smaller jets to get any sort of pressure with a back-pack, and the same small jets restrict the water too much with a 100psi pump.

Wayne, do you do a separate rinse with the brush off the glass?  If so try a couple of windows with and without a separate rinse, and then check the windows once they are dry to see there is a difference, you may be surprised.

Hello Peter,
 
I always rinse with the brush on the glass, but on ground floor windows I've been pulling the brush away from the glass near the bottom of the glass as I've found this quicker with wide fan jets. I won't rinse with the brush away from the glass at the top of the glass because the spray will just go all over the top above the frame and hit the brickwork/lintels which will then drip onto the glass after it's dried resulting in spotting. I've tried both ways of rinsing. What method are you suggesting Peter and what am I looking out for as I'm intrigued and always open to new methods and ideas if they work. I'm keen to learn, tell me more please.

I think that pencil jets are much better as you can direct the water accurately to where you want it!

[Peter Fogwill]

Sorry Wayne, I thought it was you that was going through a lot of water, I should have directed the question at Alan.  What I was meaning is a separate rinse is usually not necessary, and the test I suggested usually is a good way of proving it to yourself.  I have seen a lot of window cleaners wasting a lot of water and time, when it is not needed.
