Wfp surpasses trad cleaning hands down, there is no argument at all, only operator error,
i use both
and tbh over four decades of work, you would agree that a massively varied amount of work can be built up
there are jobs that just dont suit wfp
some types of dirty windows suit traditional methods
there are windows that just dont come up
there are customers who just dont want it (works both ways this line of thought as well)
i do straight forward upvc type jobs that dont like wfp...the windows spot etc....this isnt operator error on our part
we have a subbie thats used wfp for nearly ten years now and he still finds it on occasion inconsistent...to the point of two exact same jobs next to each other....one comes up...one doesnt
its a shame, as i am pro wfp....but in a few cases it doesnt cut the mustard
