I think for ground floor windows, if you are quick with a squeegy there's likely not a lot of difference in time on the ground floor windows (unless you count doing the frames), in fact dare I say squeegy is faster than wfp on ground floor, if when using the pole you rinse properly.
You also save your water doing that too.
For those that started as wfp users, do you generally use the wfp on ground floor windows or not?
What about those who have traditional experience?
