“Velvet lips”, yes, might induce a static charge. That’s not caused by the vacuum. You can do the same by simply rubbing an LP with a velvet cloth. Also, believe it or not, there are vacuum based RCMs that do not use a wand with velvet lips to remove liquid (Loricraft, etc). Those machines don’t induce static charge. I love my VPI HW17, btw.
Also, I never said the VPI brush gets into grooves. I may have implied it’s superior to the Audioquest brush for the purpose of wet cleaning, and I stand by that.
