I am not sure that the same thing could be applied to wfp, but imagine the possibilities if it could? Perhaps something like the carpet shampooers that suck the water back out of the carpet. Imagine using one 200l tank a month! 

I'm a CCer and had been wondering whether it'd be possible to devise a window cleaning attachment for a portable carpet cleaner!

I mean, most machines have a 100psi+ pump, sufficient to feed a pole. It'd also have twin vacuum pumps to dry the glass squeaky clean.

All it'd need is a filter and a pump to move water between the waste tank and the solution tank and bob sherunkle!

1 of the lads on the DIY forum was on about this, he said it should be fairly easy to do

Slightly different but I have thought that by blowing(plus gravity) you could create a squeegie effect that would leave the window dry.(blowing the water off,not blow drying)

The machine you mentioned earlier is supposed to have cumbersome air tubes not suited to domestic.

And even my RO waste, at about 400tds, is not advised for recirculating, so how would you process some of the manky stuff that would come?

Far more usefull if someone on the DIY site came up with a system/way of collecting and utilising rain/grey/old bathwater for 100% WFP reqiurements.

Coming back to the car wash part of this thread for a moment. Most car washes round here are hand car washes and definitely don't recycle their water. Also they were allowed to stay open last summer during the hose pipe ban. I know that for a fact because I was forced to use them to clean my taxi.

Your area (Pinner, Middx) doesn't come under the Sutton & East Surrey water supply area.  Hosepipe bans didn't affect the situation.  Only a drought order would do that.

Just another thought, how much water do the trad cleaners use per day?

I'm still trad only and hoping to move over to WFP for the tops later this year but these are my water usage figures for trad only.

Most days I use between 10 and 20 litres for cleaning windows and whatever my washing machine uses to rinse out my tools on one rinse cycle at the end of the day. Sometimes I rinse out my gear in the kitchen sink. Not quite as effective but uses less water.

The amount I use depends where I'm cleaning and what time of year it is. I tend to use more in the summer and on parts of my round that are near main roads as they get extremely dirty.

Thanks. That is about 100 litres a day (including your washing machine) for trad and 500 litres a day for wfp.
I am not knocking wfp - it is another tool to be used when appropriate, but somehow I still think there are going to be questions about this method that the trade has to be prepared for.
