 over carpet. And we talked about it last week. If you missed it in that bathtub, don't worry about it. But carpet is one of the nastiest surfaces we can have in our home. One, it traps all the dirt, dander. If you have pets, it's just getting nasty. It is just a capture thing. And unless you've got just a ridiculously good vacuum system, it's going to be a mess, guys.
