I use a piece of galvanized 1/4 inch screen to hold over the tool well as I vacuum. Just slide it down like a tray and most dust/chips are sucked up without sucking up your tools.
A workbench without a tool well? Granted, it requires a little discipline to keep it from becoming a "catchall". Just clean it and organize it once weekly. This is like tossing your tool belt for getting too full. How many steps are saves by a toolwell I have no idea. Knock a hand plane or two or chisels onto the floor because you had to leave them lying on top of your workbench, you may be ripping that cover back off pretty soon
