I have been trad since i started 3 years ago now i have a purefreedom setup, with the trad vs wfp argument i believe that they both have there places,
you need trad for when wfp cannot be used, i.e on flat roofs or houses where the rear can only be accessed by going over the garage,
inside windows
shop windows on the high street,
every window cleaner needs to be able to use a mop n blade.
WFP is faster, safer, does a better job at removing things stuck to the glass i.e spider dots etc things that you have to scub with the applicator when trad and do the glass 2 or 3 times to remove it all,
its better for in the cold when your hands turn to ice when you touch your ladders.
i've had zero problems so far when converting customers over to wfp and i've even converted custys that i have who only wanted me cause i was trad before when they sacked there previous wfp cleaner.
wfp is better for when you see a trad cleaner in there escort estate working on the house across the road, gives you a nice feeling that your not on ladders anymore haha
