Addendum:
Have the product now reduced to a star 0 stars would be fine (but unfortunately is not). Remote control and the Caddy / Stand missing. An absolute bad buy.
It is here primarily about things that the seller promises not einhaltet. Either it does not work, or it is missing, impudence.
Previous review:
Product works on the ground and at the lower edge of the walls satisfactory. Unfortunately, it does not run up the wall to the waterline.
According to the description from Amazon: "Cleans pool floors, pelvic walls and the waterline". It's really very annoying that the product is not as described. I should forgive 1 star because the information is incorrect, however, the device performs the other tasks in order (not very good). Always makes the same points in a rectangular pool of (7,5x3,7m).
Amazon gets 5 stars because they have offered financial goodwill solution within 30 minutes.
