Great idea, too bad it kept falling
It looks so easy on the video. I tried adjusting the magnets and it was either too little and it fell off, or it was too much and it barely moved. Also the way that it cleaned it was leaving streaks all over the place. Just not worth the aggravation.  I got a pressure washer and plan on using that to wash the one hard to reach window I have.  Returned for a refund.
