CarlD,
I'm on my third season with the BD remote, it is an awesome machine.It cleans my 25 X40 , 30K gallon vinyl pool in an hour .I've never had the cord eaten by the machine , but I do have some tangling of the cord , which happened as well with the Dolphin Dynamic I tested in the whole 3 days I tried it !! .AS far as the Power supply being stored under the machine, I agree while it's not the optimum place for it , I've never had a failure with it, in fact i left it out this past winter by the pool , uncovered , and just got a drop of rust by the two screws holding the connector where the cord goes.The machine goes around the pool much quickler than the Dolphins , and the factr that randomly they turn and go in a total opposite direction, really gets the pool clean, it doesn't miss a spot.As far as climbing the walls , mine was the first year model of the BD remote, it only goes up the wall on the 7th time it hits it, it WILL START to go up the wall/floor angle, realize it's on a wall and come right down, if you hit the "program" button on the remote , then it climbs each time it hits the wall.
