    Whether or not that's correct depends on a Jobo Drying Rod's vintage:

    So, sponges...they should be wetted and wrung out before using.
    May tomorrow be a better day.

    Doing that has, in my experience, absolutely no positive effect on the newer Jobo Drying Rod synthetic sponges. They're utterly useless regardless.

    Essentially yes, that sponge thingieee could be OK as a paper towel into cylinder pusher to move the residual fluids inside the cylinder around some what. Other than that, it is not a very useful Jobo item.

    Fortunately the sponges are not essential to the operation of the drums! But we are also warned about hitting the bottom of the tubes with the sponge and break the seal in the drum.

    Watch for water trapped in the lid too.

    The lid is both a light trap and a water trap in equal measures.

    For what its worth, I load my tanks in the evening, process in the morning and leave them to dry all afternoon.

    May I inquire why people don't load the drums full of water? No sticking and even application of the developer since they are prewet.

    Re: Question about JOBO expert drums

    I don't load the tanks while they are filled with water for a number of reasons. First, I don't shoot that much film, and I have a number of tanks. It's rare that I would immediately reuse a drum. Second, I don't pre-wet my film. It's an unnecessary step for BW film, and Ilford, for example, recommends against it. If you do pre-wet film, time consistency is important. 3rd, it's a pain, and it would make me load the tanks in a sink, which I'd prefer not to do. 4th: bumping the tank in the dark could be very unfortunate. That's me. If it works for you, then you should continue doing so!
    May tomorrow be a better day.

    I load at night (out of necessity) and develop the next day -- too long in the water. but I unload them that way.

    Re: Question about JOBO expert drums

    I tired once got the first sheet out on the dry side,and in the water on the wet side, then got water on my hand back on the dry side of the room on the holder and got the sheet out but sticky wet fingers bothered me, had to feel the drum to find the empty chamber and got the other hand wet and things went downhill after that dripping water back and forth.
