* Wet vacs or wet/dry vacuums—a specialised form of the canister vacuum—can be used to clean up wet or liquid spills. They commonly can accommodate both wet and dry soilage; some are also equipped with a switch or exhaust port for reversing the airflow, a useful function for everything from clearing a clogged hose to blowing dust into a corner for easy collection. Handheld vacuums can vacuum wet and dry. (depending on which vacuum)
