When you need to do a rush cleaning job (is there any other kind?), the first thing you should do is go outside. Then come back in and look around objectively, as a guest. What are the first five glaring things that jump out at you? Clean those things first. Then sit down where your guest is most likely to sit and do the same thing. You notice different messes from different points of view, so it's worth trying out a few different vantage points.
