Hi just read you website and it states that w.f.p has less of an environmental impact. I do find that somewhat funny as you use electric to purify the water causing global warming.
Then there is the fact that you using vast amounts of water. Then your van will use more fuel when loaded with water. What part of using a w.f.p is good for the environment???
I run a big traditional service that is picking up so much work from w.f.p cleaners. I won't buy one until forced to by health and safety totally banning ladders. Just thought I might point your claims to be a bit untrue mate.

Been door knocking his custies saying wfp scratches cills & window. Desperate springs to mind
Taking his points.
Electricity isn't necessary for purification so long as there is half reasonable water pressure (non pumped system). Leisure batteries can mostly be charged by engine movement though it is true that a bench charge is needed sometimes.
Using water in itself, is not environmentally unfriendly. It might only appear that way due to incompetent water companies not investing in infrastructure.
Fuel usage. Yep. He's right about that though I would qualify it. With WFP, much larger jobs can be done than with ladders so it is possible to work all day on one location (or very few anyway).
I've never pushed the environmental aspect myself as I know it is possible to challenge it too easily.
