I've used the bath towels in the past, but lately I bring in wet vac. Reason is lots of people around here have wood floors and get freaked out about water on them. I usually block up drain tube (I carry a variety of sizes of rubber stoppers) and lay a small towel down. As drain pan fills, I hit it with wet vac and usually get no mess at all. I have a variety of steamers, a Shark, a Sylvania, some other brands. I get them when there on sale, and have right now 5 extra ones in my garage. The winter is rough on them, and I usually go through about 3 a year.
