Bests & Worsts Reviews from Amazon

I’m an EE who has spent a decade in robotics. I’ll cut to the chase. Buy this one. It isn’t perfect but for $199 it’s a solid value. What astounded me was it’s ability to get two years of dirt off an exterior window with DRY cleaning pads. Watch my video. It can’t get every bit of a corner but it gets enough. Inside it gets film off well. I make my own liquid to lightly spray onto the pads. I use generic windex from the Dollar Tree and mix in about 15% of their 50% rubbing alcohol. Works great. I am Very pleased with my purchase. Hope it lasts a long time. PS you can get the same item on eBay for about $130 but I chose to buy initially from Amazon since I knew I could return it if dissatisfied. Buying direct from China often has risks and hassles if you are dissatisfied with your purchase.
