i do all windows wfp up and down all the time and only use trad for insides.
bought my round(some of it) of a chap who was trad and immediately told the customers that i use wfp.told them all they may get a few streaks first clean but would be better the next time, had about 5 complaints out of about 300 and all were happy when i went back and poled over them again.
its much quicker doing the bottoms wfp and you can even wash the upvc sorrounds in less time than it takes to do windows trad.
even the little old ladies come out(getting drips down the back of the neck!) and tell me how impressed they are with that "pure water thingy" and they also remark on how quick and safe it is. bless 'em

Because I still need to save water (I find it no effort to keep the belt on with blade and app.) I will usually do front doors and when low on water some patio doors trad - especially if the water running on the ground might freeze. (Accident avoidance)

when water conservation is not a problem you will find it so much easier and quicker, only prob i have is brushing the cobwebs off my squeegee!

ok,

Results of time and motion studies

First off I did the downstairs traditional.

Timed on the kitchen door, which is a half georgian one-10 panes of glass. 2 min 45sec
rest of downstairs windows (bar 1 that needed a pointer ladder to get too and I couldn't be bothered ) which is another 4 windows-3 of which are the sadolin stained, 2 panes of glass type window, and the other one also has just 2 panes of glass, but the one pane is an opening light along the top.

Including the door, which makes 5 windows, time taken was; 6.06 min

Did whole house with WFP (apart from back) 5 upstairs windows (2 panes per window) and 7 downstairs windows (including the whole of the front door and the window I would have needed a pointer to get at.

Time taken 4.40 min

1 minute and 26 seconds faster for 7 extra windows.

Individual time for a single window.

28 seconds trad
11 seconds WFP

The same ground floor window.

Niether method was done at race speed, but trad was done at a 'busy' pace, frame wasn't cleaned, sill had light wipe over, edges had a very quick detail.

WFP was at normal working speed using roughly 2l per min and included everything.

Must say that I was genuinely surprised just how much faster WFP was on a ground floor window.

Oh Ian, you are a donkey sometimes... :

I know how mucky your windows are, they're like mine.

If you'd got the dirt off with the detergent first, then you were wfp'ing a clean window...of course it's quick!

If you'd done wfp first it would have taken ages to get dirt off and left spots and runs as you have wooden frames.

I think maybe try two windows the same?

Well I thought I'd comment now.

Thanks for taking such an interest guys, especially experiments too!  I didn't expect time trials.
Good forum this.

Well my reasons are a bit like Rich from P@F:  Once I've got all set up, hoses connected, pump on, pole sorted...I just can't be bothered to start with mop & squeegee.  It's laziness more than anything.  Mind you, strangely I do find I am quicker with the pole even on ground floor stuff, and not so tired, or aching.  Plus I've sold customers on this as my preferred method now.  So they're getting used to it.  Job done! onto the next one.

HOORAY FOR PJ !
Im glad to see im not the only lazy one out here !

Laziness is a powerful motivator

[Ian_Giles]

Rog,

The individual times were done after the windows were already cleaned.

The windows downstairs may have been done first with trad methods, but the 7 extra windows were all equally dirty, and were all upstairs too, and I was still way quicker.
Also on the frames of the downstairs ones, were various cobwebs and spider eggs, not removed with trad as I didn't do the frames, extra time was taken with the WFP to remove these.
The first time clean took more than 11 seconds per window with he WFP.
The first clean with trad also took longer than the 28 seconds.

the comparative times were on clean, identical windows.

what were the results like ?? ??

Rog,

You make me laugh mate.

Ian

do you have a family??

I think you may be taking this all abit too seriously..!!

[P @ F]

Steve K , im glad you said it , hes a mod you know ! ! ! !
I thought i was anal about things , but Ian is the master !
But when all is said and done , you have to admire him for the dedication !
SLURP , SLURP ,SLURP !

Saying that , i wonder how many of us will be out there in the morning with a stopwatch !

I also mix and match.

As i have my son with me i do the tops withs wfp he does the bottom traditional.
If we have a row of houses i go along all of them doing tops and when i get to the last one i work my way back doing bottoms with wfp and meet my son somewhere on the way back.

If im on my own i WFP lot or if its leaded i wfp the lot my son just does the front door

Matt,

On the windows the results were fine, not a spot in sight.

The kitchen door was another matter though, with the WFP it came out crap! Spots everywhere

The reason for this being that it is in a poor state of repair and desperately needs a coat of paint
a lot of bare wood (is, or was, a varnished door) due to weathering.

Steve,

I do get anal about these things
Or pedantic perhaps, I enjoy doing time and motion type experiments, sometimes you may feel you are really flying with the method you are using to work with.
But you drag out the old stopwatch and compare methods, the results may often surprise you.

I did once and me and her have been in seperate beds since

HI ALL
THIS IS MY FIRST TIME ON THIS SITE SO 
I HAVE JUST ORDERED  A WFP SYSTEM COMING IN 3 WEEKS TIME,
I AM ABIT UNSURE OF HOW MUCH WATER I WILL BE USING
I DO ABOUT 10 TO 12 ,3 BED HOUSES ABOUT 6 HOURS OF CLEANING TIME.
THE GUY THAT MAKES THE WFP SAYS HE USES ABOUT 6 TO7 25LT OF WATER DOES THIS SOUND ABOUT RIGHT?
PLUS DO YOU LOT THINK I CAN MAKE ENOUGH WATER THE RO DI FILTER MAKE 300LTS IN 24 HR
ONE MORE THING A LOT OF MY HOUSES I DO HAVE LOCKED GATES SO I WILL HAVE TO GET OVER THEM
AND RUN A HOSE ROUND TO THE BACK DO YOU THINK A 30 MTR HOSE ON A REEL WILL BE OK
THANKS
 YOU LOT
I LOVE THIS SITE   STU   THE WFP WALLY

Hi Stu,welcome to the site all the best with your new system believe me you won`t go back,it`s all up hill from here with no climbing  ,Gaz

[Moderator David@stives]

no
No
and no

I think you answered the question yourself

[Ian_Giles]

Hi Stu and welcome to the forum

You should really have stuck your post into a separate topic of your own!


For the work you have your R/O - DI setup is more than enough for your needs.

If you are using 25l containers, would it be right to presume you are using a trolley system?

If you are working out of the back of a vehicle, and not using a trolley then you really need 50m of hose + the pole hose too, 30m won't always be enough....then again that does depend on the work you have of course

Most people will use approx 15 litres of water per standard semi, considerably more on the first clean though.
