Can you use a Swiffer wetjet to clean hardwood floors?

Yes, the Swiffer Wetjet is effective at cleaning hardwood floors, whether real hardwood, or manufactured wood flooring. Proctor & Gamble, the manufacturer of the Swiffer Wetjet, sells a liquid hardwood floor cleaner that works well to remove surface dirt from the wood floors. The Wetjet works best on floors that have been sealed first, rather than bare wood.
