The Ninja Foodi lineup consists of multiple models, each with its own unique features and capabilities. While specific differences can vary among models, the key differentiating factors lie in their cooking capacities, functions, and included accessories. For example, the Ninja Foodi Deluxe models often offer larger cooking capacities and additional cooking functions like pressure cooking and broiling, while the standard Ninja Foodi models focus primarily on air frying, roasting, and dehydrating. It's important to carefully compare the specifications and features of each model to find the one that best suits your cooking needs.
