content: I purchased this pool cleaner to replace a Kontiki cleaner that worked pretty well, but fell apart b/c I always left it in the pool (turns out that I can replace the part and keep it as a spare...if I need it!). I unplugged my old one and plugged diver Dan up to my old hose (kept the new hose in the box) and dropped him in, turned the pool on and sat and watched. My first thought was, man he is so slow! I gave up on watching him b/c it was like watching paint dry...lol. When I returned about an hour or 2 later I was amazed on how clean the pool was. Diver Dan moves really slow but picks up all the dirt without disrupting the surrounding areas and thus makes my pool far cleaner than my old creepy crawler style cleaner ever could. Diver Dan does occasionally get hung up in spots on the bottom, but he eventually turns out of it. My old creepy couldn't do that! I love Diver Dan, although we did rename him to Scuba Steve!
