Scrub a dub dub!

So tomorrow, a professional cleaner is coming in for 3 hours - I bought an awesome coupon on one of those city-specific sites that are popping up all over the place. 

So this means I should probably put some effort into picking up the house, right? I want them to do the floors. Which means the floors should be visible, unless there have been some sensational advances in the cleaning industry since I last looked. Anyone know? Anyone?
