hi guys
dont think much of 2 jets running out the ends of the brush
does a very unsatisfactory job    can miss on a lot of area of glass
just ordered a pair of fanjets  arriving in the morning    i imagine
they will do a better job   

i bought a cheap flower spraying bottle  handpumped using the finger
unscrewed it, connected its suction pipe to the 12volt pump  it worked!
im thinking of connecting 4 of these in line using t junctions and attatching them to the top side of the brush
there would have to be a top plate to stop the spray from wetting the top frame and brickwork
would have 2 microbore feed pipes    1 for washing and 1 for rinsing
with a manually operated valve near the end of the pole

this is going to take some good amount of time to construct

before i get going on this project, has anyone tried this?   what makes this a failure-even before i start?    might save me from wasting my time

Never come across it before, so carry on. Prob with top plate is that the water may still spray upwards under the top plate because of the angle and pressure. I use 4 pencil jets, one pointed at each end. Like the idea of using reduced flow for washing and increased flow for rinsing is interesting as we are all supposed to be using less water beecause of the drought situation) but you could do the same, but just turning the flow down for washing and up for rinsing. I use a controversial max 1/2 litre per min.
You may find that various hoselock irrigation jets do something similar as the spray bottle heads.

Don't want to stop you developing your idea, but you might care to know that there is already a brush fitted with fan jets, it might be useful to look at it, try here:

Yeah but not in the way jikwan wants to do it! Read his post again!

On some brushes we use a similair system to Jeff, 4x smaller jets spread across the width of the brush. This provides an even coverage of water on the window, without the overspray issues of a fan jet. Best of both worlds.

Jik this is one way of doing it, fan jets need pressure, these pencils dont so when the brush is pressed on the glass the jets hit the very top edges of the brush and there is no splash. remove the pressure and you have an ott rinse. Note the end ones are aimed at the edge of the brush. Its just a bit of kitchen (plastic slider bracket) Its also possible to go thro the head of the brush if thats what you prefer, but the manifold is only held on with 2 small screws so you can change over to a new brush when required.

just recieved 2 fanjets in the post    exactly 10,000 times better than
those confounded pencil jets    i wonder how anyone using them can
do a good job and not use too much water   
the guy i bought my 2nd hand system from used 1&half lit per min

further experiments with spraybottle nozzle (still using a single nozzle
rough prototype) there is already a major problem

spraying gives really good coverage very fast but leaves hundreds of
little spots of water    because spray has no real weight, it will stay where
it is, unless its lucky enough to join another spot and it may run down

leaving a window full of spots isnt the most satisfying experience

seems like the solution is spraying with such force that it swallows all
spots in its wake

hi jeff
your pic
looks like a very simple easytodo setup
using penciljets?
wouldnt you get optmum coverage if the 2 central jets were fanjets?
is this what you use yourself?

[Jeff Brimble]

Because I use a low pressure sytem I have tried useing  fan sprays which need presure- I may be missing out, but pencils  work 4 me.
Force will still leave spots.

Ive used 3mm pencil jets for 4 years without one single spot ..it depends on the operator rinsing.....also with a varistream you can alter the flow rate of water.. i have a 700Ltr tank on board and can get 50 3 bed detached houses from that one tank

leaving a window full of spots isnt the most satisfying experience

Operator error again you cannot leave spots if you know how to rinse properlly

[geefree]

Hi,

do you guys wash and rinse frames first then wait.... for drips.... before doing the windows...

i should be up and running with a packpack for wfp this week so havent done any yet, my pole came with a small soft brush (small) ,, with two pencil jets...

but the bristles flatten the moment it touches the glass,

i think its way too soft...

and i cant get near window sill...(.own house)

i think i will get the vikan splayed siil brush,

does any one use this?...and is it ok for the whole job?

cheers

gary.

[Jeff Brimble]

Yes, wash and wait.
Not too soft, not too hard and not too long.
Try what you have for a week before you change (give it a chance)

I have also used pencil jets for over four years with no problems.

Just a point when using WFP systems its not about spraying water onto the Glass but about rinsing debris and bits off and you need water volume to do this not just a pretty water spray that looks good but does not put the water onto the glass to do the job.

hi Eclean
right, penciljets dont leave spots
its the fine mist comming from cheap plantsrayers that make spots
i have not abandoned the jets-delivering-mist project
jeff thinks delivering mist with force will still leave spots
my intuition says its possible  there just needs to be a very particular
arrangement of jets, pressure, angle and whateverelse

thanks for your contributions guys
