\\\what about when your cleaning the window and your hose snaggs, and lets face it thats alot!! does the water shut off? and what about when your moving on to the next window, and it snaggs on a rock, does it turn water supply on? just trying to work out if they worth it? Also, say i get a brand new carbon pole, do i really have to hacksaw the end of it to fit the aqua dapter and totaly invalidate the pole warranty? or does it just retrofit without damaging the pole?
