I use my shop vac to clean up the bottom of the board it's mounted on. Since I'm already there and the vac is running I do a quick pass through the hopper to get any big stuff.
If the static didn't cause a bunch of chaff and dust to stick to the board above the bucket I wouldn't even do that much. Humidity in Iowa (and many other places) can go from 15% to 95% in a few hours several months of the year. I don't want to have dust clumping everywhere in the shop so I vacuum, a lot.
