Sawdust up my nose!

I feel like I have sawdust everywhere. We have started on the great mission that is refinishing our floors. We rented one of those big sanding machines and it got off a pretty good layer. Now we need to do the right beside the wall, which is about 4 mm higher then the rest of the floors, and a the spots the big machine did not get too.This is the hallway, it has just has the big sander. You can see here what I mean of the the edges needing more sanding.
And this room is done sanding! Yeah!
