I normally love my flocked brush but it was a nightmare this morning, even on full flow. There was so much debris on the windows and ledges from the wind yesterday it clogged the brush on the first house and then proceeded to come off all over the next one, and the next. After a couple more houses I gave up and popped my X-Line mono on. Forgot what a nice brush that is. Much better for this kind of work. It's chucking it down now so it's coffee time.
