It doesn't work both ways - an arduous attempt to get the sprayer to work. The fabric upholstery is thin and difficult to clean. I have returned the product. I have a Hobot 528 that works great for my large windows. I'll probably buy a smaller Hobot for my regular windows. They're more expensive, but seem worth it.
