just adding to smudgers  post, i too feel the fan jets on high flow (60) for me are better for regular maintenance cleans, i use gardiners low pressure fan jets (red ones)
But i do find pencil are far better for first cleans, leave less spotting or no spotting compared to fan jets, i have both sets on the same brush and just change for jobs

Never used a sill brush, so can't comment I use super light dual trim, rinse on the glass or lift off a few millimetres no more than 25mm (1 inch)

Same here, SL dual trim - rinse on, full bore.

i have a 400 tank, if i had my pump on full i would be out of water by lunch, dont understend how you can work with pump on full

or am i missing something

Perhaps you should try it one day and see what happens.

but id be out of water by lunch lol

Today I did 4 and a bit hours on the glass ... went out with 400 litres and came home with 150 litres.

No aquadapta.

Pump on 66 which from reel gives me dead on 2 litres per minute.  (80 gives me 2.5 litres a min)

Did total of 16 jobs

8 x 3 bed semis no connies
1 x 3 bed semi with conny
3 x 3 bed detached
1 x 4 bed detached (3 monthly clean   ) LOTS of rinsing
1 x front only
1 x 4 bed with large conny
1 x 4 bed no conny


Try it you have nothing to loose and lots to gain  

personally I wouldn't consider 2lpm particulary a high flow but I can
clean just as quickly with considerably less  flow on four weekly maintenance
cleans and I don't rinse unless absolutely necessary.

With a 10 LPM pump, 8mm hose and two fan jets its been coming out of the brush head at 4.5 litres per minute.

Must admit ive always been curious about using fan jets but never got round
to trying them.

I imagine even using 4.5lpm its not bouncing off the glass like it would
with a pencil jet which I have found when I have plugged into a customers
outside tap

Even being a backpack user like myself where the pumps only max at
3.1lpm using 5mm hose its given me something new to think about trying.

Could somebody please post a video of this technique in action please 
Thanks, Phil....

I upgraded this week one of our WFP pumps from an off the shelf 5.3 LPM to a 10 LPM provided by Vyair. Initially I had problems with it as the pressure switch seems to be faulty. So this morning I bypassed the pressure switch and worked with it on full-bore and BeJezus! it makes one hell of a difference to work.

Id say that Ive found a number of noticeable incidences that have affected my working life in a positive way. Initially changing from trad to WFP, then from trolley to van-mount then from van-mount to two man and on up to the current Grippa system we have. I would put upgrading to a 10LPM pump in the same bracket as those other changes.

It makes a cracking difference, windows really do take seconds to clean, literally. I would recommend it to anyone who has the capacity for the increased water required. Saying that, dont go thinking you use 600 litres an hour. The figures quoted by the manufacturers are at full pump potential, so with no resistance created by 100 metres of 6 or 8 mm hose and with no nozzles. In reality it was pushing out a fraction under 4.5 LPM at the brush-head, knocking about 60% off the quoted figures.

We also checked how much a 5.3 LPM pump was producing at the brush-head and this was 2 LPM.

So an improvement of twice the output at the brush-head, which is inline with the figures the manufacturers claim without resistance.

Vyair do a 10 LPM pump for just under £70.00, the same pretty much as a regular 5.3 LPM.

so happy i just found this post came on here to ask if i buy a pump will a stronger flow help!

i don't know about all these figures but we bought some work off a trolly dolly guy said we would only use 200 lts for this round

1100 we used to do it that day only had 100lts left in the tank they were minging !!! all the customers loved the clean windows why do people skimp on water and rinsing

shame their website makes my head hurt 


did you know they do a 12 litre version as well 

Much cheaper off their site than via Ebay.
