My skepticism was unfounded - this product works great!
I purchased primarily for my large sliding glass doors and adjacent fixed glass wall panels and this robot did an amazing effortless job cleaning them to perfection. I haven't tried on my glass shower walls yet but I plan on doing that next. I would recommend.
