Bought this since my mother and sibling had one and I was blown away on how to use it in a shower and even on windows. My wife and I actually walked I to a glass sliding door because they were that clean
I wasnt expecting too much from this when i bought it but i actually think its really good. It did the insides without much effort. The outsides i thought were done but the next morning, with the sun shining on them, were streaky. I did them again, took me 10 minutes and they look great. I think an extra pad would be a good idea for doing outside windows as when the pad gets dirty it causes streaks when it drys
With COVID I skipped having my windows cleaned by my wonderful window cleaner and they got pretty bad. I ran across this product and decided to try it, I’m so glad I did. For the outside windows I first cleaned the grime off with a bucket of water with a little ammonia and liquid detergent. Our downstairs is entirely divided light French doors and windows with lots of ledges that collect dust. Then I used the window cleaner that comes with the vacuum squeegee and then the vacuum, perfectly spotless and streak free windows! The cleaner smells great, by the way.
