How to remove sawdust that is left after a good vacuum?

Q: I have just sanded my oak floor. I need to know how or what I could use to remove all of the sawdust that is left after a good vacuum.

A:You could use a micro weave mop or a towel wrapped around a push broom. Just go up and down the floor like a Zamboni machine, turning the towel as it gets clogged up with dust.
