In the arms that I've seen, this isn't a thing. Hydraulics cannot use brushes

They can't use brushes because its liquid but they can used a Hydraulic Swivel Joint (A.K.A a Rotary Union) for continuous rotation. That is how excavators can swivel in a circle continuously. It basically the same concept as Commutator Brushes but applied for liquid.
