http://img22.i.us/i/dsc00032pq.jpg/i will try and get the name of them ladders for you (the vans not here at the moment) and yes there is 2 of us.
im not knocking wfp, i still use it on all hard to reach windows, and the work is much easier, but thats not the reason we got wfp, we got it to speed up our working day but it didnt do that in all areas.
eg on this estate with ladders from the time we get from van to house 1min, clean house 10min and back to van 1min 12min total
same estate with wfp is more like from van to house 5min clean house 8min and back to van 5min
on the other hand a big country house we do in 25mins wfp or just over an hour trad
