I bought a robot window cleaner from this site. First off. They only have an answering service to talk to when you have issues. The window cleaner no longer works after owning it for three weeks, it is flashing red and won't start. I have sent three emails to the company who have not responded. It is a waste of $350. This is a difficult website to deal with and their response time to sort out a robot that no longer works is appalling.
