The Mop Mob is a play on words a bit. It's as if we are part of the American Mafia (the Mob) who will kill germs and uncleanliness. The logo doesn't have to feature mobsters or slick criminals, but that might be something to consider. We don't want it to look hokey or silly though. You also don't have to use "the" in your logo.
We are definitely looking for a clean, masculine logo. Similar to the ProForce logo here:
