I would say given a choice most window cleaners would like to have a pure water system of some sort but for some its cost prohibitive and for others they just dont want to deal with the hassle of checking this and calibrating that and all the other little things that seem to go along with it, theres one thing you can be sure of your ladder will start in the morning
Good point Pat. I run a Tucker (di only) for me its great, its not brain testing which is right up my street as there's varisteam, pump, filter to pump to clean now & again & di resin, its a simple set up so if i can keep on top of it anyone can, even Squeaky.
Since i've switched to wfp which is coming up for 10 months, i've completed my work on time every 4 weeks, so for me its paying for itself. Also i lease mine, no big money up front but the extra payment is covered.
I just feel us wfpers go on about the speed & loads of extra money it earns (me included sometimes) but forget to mention the other good points. So the likes of Squeaky & Co all come out guns blazing.
