A Michigan man was arrested for "receiving sexual favors from a vacuum", which appears to be such a problem that Michigan specifically has laws against it. The police were probably just having fun by describing it that way to the press; the actual law was most likely something along the lines of "appliance rape" (can a vacuum give consent?). If it were illegal to have sex specifically with a vacuum cleaner, in general, wouldn't the coin-op vacuums at the car wash count as prostitution?
