its NOT quicker generally ive found.
today i had a commercial job first thing and i usually trad the entrance windows and a few door panels to the side but with it being wet i just wfpoled everything.i was about 5 mins quicker.
i use a high flow with hot water.its very fast to clean a window,frame and sill thats normally cleaned wfp.
some ground floor windows are just as quick trad but not quicker.this is on tight space work or large plate glass windows but thats it.
im no slouch with a squeegee either as ive 20 years experience using one.
