But i must admit ive only cleaned my house but ive been left with alot of spotting used 30ltrs of water on 11 windows also i feel its a cheating way of doing window cleaning, ill give it a chance but my results from trad were very good i cant see the wfp will or can be as good.
I mainly wanted a wfp setup for hard to reach windows, but doing my house it seemed as lot of messing about and the result weren't that great but i will practice, i have a shurflo backpack what speed setting should i have it on, i had it on 2 is this ok or would 3 be better.
