Hi JoyfulNoise,
I know you are a great poster and have a lot of knowledge, however my experience has not been like yours. In another thread I did a review, I posted picture of cord when I first put it in pool and then after 2 cycles and you can see it is twisted. Maybe I have a defective unit. I can't find thread it was last year and photobucket sent me the email of no 3rd party hosting, I will have to try and find original pictures. The APP works when I am 2 feet away from it, when I am 10' away it is very intermittent (there is a wall with a window between myself and the base at this point) My Bluetooth speaker for my phone works much better. The timer function while only 7 days is only a 1 event timer, I need 2 cycles to get the whole pool done but that could also be a function of the twists in the cord altering the path. It hangs up on the drain and takes a very long time to free itself if I have pump drawing from bottom drain, with pump off it hangs up but frees itself. I called maytronics last year when I got it. They gave me same line you just did about wrapping cord. I worked as an electricians helper getting through school, I know how to untwist wire as well as coil it. I do it pretty much like you say above. As for the drain they said get a lower profile drain but could not give me any specific name or model # that would work with it. Bluetooth does not work through wall (unless it is my speaker). I have not updated app. or played with the app after the call to Mattronics, I just use it like the active 20.
