The video shows a Cyclone & Modified Cover.
A Pool Owners Guide to Closing - YouTube
Again, same concept. I am assuming that if they went into a lot of detail, people can just watch the video until comfortable. I am not in agreement with the burping process of return lines, especially if you are using the Cyclone. The Cyclone will remove every inch of the water in the return lines, especially if you lower the water below the returns. The burping process is great if your blower does not have the volume needed, and this can be done several times until you are comfortable.
Nice video, but they needed to explain a little more about the Cyclone (why they use this blower instead of a compressor or shop vac), and why they created the modified cover. The threaded plugs also leak, even with Teflon tape. I had ordered them and the manufacturer told me that they are designed for AGP. Best to use black expandable rubber plugs. I do use the threaded if a return needs to be closed off during the swimming season for some reason (usually to increase pressure for aeration with waterfall adapter).
All you really need is the modified cover, hose, and Cyclone. Everything else is done at the shut off valves. No disconnecting of any other parts. My heater has no drain plug and I do not even remove the threaded plugs in the pump basket. Only items removed are the sight glass, pressure gauge, drain plug on filter, and then winterize the filter (between two positions).

Not sure if it could be simpler then removing suction side connection and connecting your cyclone to that? Buy the same union that's on your pump and you now have both connectors to blow out suction lines and blow out return lines. The beauty of screwing it on leaves you able to go see when everything's clear of water
Often times, there is not enough slack to hook up a hose this way. But some have flexible piping and this will work.
