Unless equipped with the right tools, regular "Dry" vacuum cleaners are not meant to be used on wet surfaces or vacuuming liquids.

Retail stores, restaurants, or any outfit that is prone to a lot of traffic, especially during the winter months when employees or patrons walk in with wet boots and bring in slush, salt, and wet snow onto the floors, can definitely benefit from using a Wet Dry Vacuum Cleaner.
