A 2.5 gallon / 2.5 horsepower shop vac unit is what you want for around $30-$35. The 6-inch brush attachment which you'll need to order from shopvac is what you want - will give you more than twice the suction power of the 12-inch attachment, and has far more brush on it. Go ahead and order two of them so you'll have a backup, or have one to use for each half of the table, so you're always vacuuming your cloth with a virtually clean brush. I use a hand held dishwashing stiff brush to completely clean off the brushes between usages, including wetting them down under hot water while cleaning them, so I'm always using a perfectly cleaned brush before vacuuming my tables.
