We had someone sweep it out. 

Whatever you decide will be best for you - BUT - if you do re-finish the floors....MAKE SURE you do the prep & clean work....after sanding - sweep at least twice.....then tack cloth (you can make them yourself - basically a rag with mineral spirits - VERY easy) - I went over the entire floor twice - I might even suggest three times....it gets the "crap" out of the pores of the wood & lets the wood take the stain much better....and the more coats of poly, the better - but take your time - as they ALL have to dry...MAKE SURE they are dry...
