If it could travel around all sides of the tank I would buy one right now. It only does one pane, though. Why pay $300 when only 1/4 of the sides would be cleaned without intervention?

Edit: As far as my skills go . . . I can build you a map to where you need to go to get someone else to build you something useful.
