I was told it's always best to fully flush things through by using the muffs.
If you've ever connected the hose to the connector and turned it on, you've seen water coming out all over the place on the LU.
I feel perfectly comfortable using the hose attachment. Apparently the designers do, as well, as they keep putting them on the motors.
Not sure how the "don't use the connector" thing got started, but I will say it's a pretty pervasive opinion.
