If you had the right window, this might be helpful. And, possibly it would be good for a large car or van this a high windshield that you can't reach on foot. I tried using it on my casement windows, and it is good for reaching the high areas with the sponge to wash them, but the squeegee moves too much and I got a lot of streaks. I then used a papertowel attatched to the sponge end to try and dry the streaks. I'm sure this has some good uses, but for what I needed, it wasn't quite enough.
