The ancient Roman kitchen was known for its innovative use of technology, including a built-in vacuum system for crumbs. This system, known as a 'murus culinarius,' was a series of small channels built into the kitchen floor that would collect crumbs and other debris. These channels would then lead to a central collection point, where the crumbs could be easily removed. This vacuum system helped to keep the kitchen clean and free of pests, ensuring a hygienic cooking environment.
