I am glad to have found this forum and thanks to all the folks for their input on the Aiper Scuba S1. Due to soaring energy cost in my area, I have been interested in an independent robotic cleaner. I have a 25 year old 40X20 free form inground pool with an attached spillover hot tub/spa. I have had several pool cleaners over the years and they all have their strengths and weaknesses. A neighbor has a corded robotic cleaner but unhappy with the cord tangling up constantly. After reading many reviews on the Aiper S1 I decided to make a purchase. I bought it directly from the company and saved a few bucks using their promo code. I initially got a purchase confirmation but its now been over a week and no further word on the status of my order. Their website has a tracking link, but it just shows "in process" under my order status. Very disappointing with their lack of communication following my purchase. I hope it is not a sign of further disappointments.
