I noted in the video they reeled the cover up but did not unreel it, when putting the cover on the leading edges must be pulled out to guide the cover or it bunches up so I do not know how they accomplish putting it on without any assistance. I did the pull cord also, Polypropylene rope floats so it makes a good pull cord and not much strength needed so it can be small diameter. However I do suggest manually unrolling the cover most of the way first, I tried unrolling the cover by pulling on cord and had 2 issues. the pressure will cause the plastic cover to rip at the attachment point over time and it pulls my reel over if I pull too hard/quickly. Also, in the video I saw the reel did not have wheels, I store my reel away from the pool when using the pool so large wheels that can go over grass are a necessity for me.
