That was an interesting video mainly to demonstrate the striking lack of real performance in a lot of these tauted tank systems. I'm fortunate and I think a lot of other RVs are plumbed the same where the toilet drains directly down into the black tank and is generally somewhat located near the middle of the tank. I bought the intank "swivel stick" rinser and think it does about the best you can do in not only cleaning, but even helping dislodge clogged outlets and even breaking up the "pyramid of doom" providing the pyramid hasn't turned rock hard. At least for my usage the rotating head on the swivel stick and the ability to adjust it's location up and down inside the black tank thru the toilet allows me to really not only rise the walls, but clean the in tank sensors. Also, the rotating jets of water from it are really strong and helps break up any larger "chunks" along with other more solid waste such as a wad of toilet paper. Of course if your toilet is not plumbed directly into the black tank then something like the tornado is the best you can do. Of course the biggest draw back of something like these toilet wands is you have to either run a hose into the bathroom or have a fitting and method of hooking them up from inside the bathroom. I prefer to run a hose directly to the outside faucet and w/o any pressure regulator on it for max pressure and I'm fortunate in that I can run the hose in thru my bathroom window so it's quite convenient.
Like what evidently happened to the OP with some sort of "CLOG OF TOILET PAPER" I had that evidently happen once and was able to clear it fairly easily using my swivel stick in tank wand. One thing with these to remember is not to actually let the black tank fill up to the brim since you have to have some tank room when using the wand to try and break up any obstructions since it is putting additional water into the tank and unless it can drain out it will continue to fill the black tank.
