Cost isn't the major issue here - I'm looking for maximum results. The
company I've used before utilizes some sort of carbonated/chemical stuff
that leaves virtually no odor, so the substance doesn't enter into this,
either.

There are some good rentals. Rug Doctor is on I used. IMO, if cost is not
an issue, get a pro as they have better equipment and do a better job.
