I am thinking of changing over to WFP, but not sure as I live in a flat if I will be able to make the water up. I have a Partner van so could go for a van mount or hire a van and system or even perhaps a trolly system. I currently clean internally windows on several blocks of flats and the contractor cleaning outside is emigrating so I have been asked if I would like to take on the outsides. Knowing next to nothing about WFP I do not really want to spend thousands on something until I know I will be happy with it.
