Alfawise WIN660 Robotic Window Cleaner,Magnetic Vacuums Robot Automatic Smart Glass Cleaner Smartphone App or the Remote Controlled for Frame/Frame-less Windows High Building ,2min/sqm (Square White)

I already own the other Alfawise window cleaner but it did not work with frameless windows, so I purchased this one. There were no reviews yet, so I took a risk based on being relatively pleased with how the other unit works on framed windows. Let me save you from doing the same...Despite it being advertised as working with frameless windows, it does not.Got stuck on the first pass and every pass after that.

the products dosnt work i want my money back
