During my brief foray back into vinyl, I picked up a manual vac unit from a member. Don't remember the name of unit or member, but I thought it made a huge difference over what I remember from my days with records back when I was young. I have no idea if the spin doctor thingy works or not, but I just don't think wet brushes cut it. If on a budget, I would try to find the cheapest vac unit you can. Maybe something like the Record Doctor unit?
And a carbon fiber brush for daily use.
I mostly bought used vinyl and after cleaning, I would hear only an occasional tick or pop. Spend the money if you are committed to vinyl. Think of as essential component.
