Vacuum-powered wipers should have "For Entertainment Purposes Only" printed on them.
Had vacuum wipers on my '49 Chevy pick-up back in the early '70's, vacuum wipers sucked back then too.
Electric on my A today.
When my vacuum wipers are working well with a new blade they work OK when I am driving at lower speeds and around town. As long as you have a lot of vacuum they do OK. They start having a lot of problems when you are climbing long uphill grades and there is no vacuum to drive them or when you are driving 45mph plus and the wind lifts the wiper off the windshield. The good news is RainX on the flat windshield does work wonders.
