Ergonomic Intelligent Dishwasher comprising of closed-loop carousel system, tableware storage holder and a Wash-Pod. Individual tableware is inserted through an opening where the tableware attaches to a closed-loop, speed-adjustable carousel-system that moves the individual tableware, in a queue-fashion, through one or more wash cycle as the attached-tableware travels towards the tableware separation-mechanism. Tableware separation-mechanism is activated or deactivated for each individual tableware in the said queue on the carousel based on user-define setting or an internal quality-control process, thus, when deactivated, attached tableware on the carousel continues to travel through additional said cleaning cycle in the loop until such time when carousel-tableware separation-mechanism is activated.
