I know the neck cleaners have been a thing for quite awhile but can someone tell me why they're such a good idea?

When I clean my skimmer (2-3 times a week) there is sludge on both sides of the neck of the collection cup and to be honest 65% of it is on the wet side with the lesser amount on the side where the liquid is collected.

I always figured that was just an easy place for the organics to start collecting and am glad they're out of the system. Why would I want to not collect stuff there and wash it back into the skimmer body? Sure some of it will then be picked back up by the foam head and moved to the collection cup but some of it is bound to end up back in the system.

Just trying to understand why people want them...
