To Steam or Not to Steam...

I am debating on whether or not to rent the steam cleaner for this weekend and steam clean the carpets. They aren't in dire need of it, but it is spring cleaning time and I finally have the kitchen re-organized. Plus we want the house to be as spiffy looking as possible because we are leaning towards asking our landlord if we can go head and get another dog, and we figure he is probably going to want to come inspect the place to make sure we haven't let our little munchkin tear anything up, which of course we haven't.
