Build Quality & Design Comparison
When it comes to appearance and build, both the Ninja SP151 and SP101 share the signature “Flip-Up” design, allowing vertical storage to save counter space. However, the SP151 pulls ahead in terms of aesthetics and finish. It features a more modern brushed stainless-steel body that gives it a premium look, while the SP101 tends to have a simpler and slightly more utilitarian design.
In terms of physical layout, both have intuitive control panels, but the SP151 includes a digital display that is more vibrant and user-friendly than the dial-heavy interface of the SP101. If you care about how your appliance looks on your kitchen counter or you prefer a cleaner, more sophisticated design, the SP151 will likely be your pick.
Performance Comparison
In practical use, both ovens heat up fast and deliver crispy, evenly cooked results. However:
- SP151 shines in cooking thicker items like roasts and casseroles thanks to its roomier interior and more intense infrared heating.
- SP101 is excellent for wide but flat foods, such as pizzas, toast, and air-fried snacks. It also preheats quickly (within 60 seconds) and includes a convenient Keep Warm function not found in the SP151.
Both models cook meals in 20 minutes or less and offer up to 75% less fat compared to traditional frying.
Cleaning & Maintenance
Cleaning is an important factor when it comes to countertop appliances, and fortunately, both the SP151 and SP101 are easy to maintain. They come with removable crumb trays and accessible interiors, allowing you to wipe away grease and crumbs without much effort.
That said, the SP151 has a slight edge in terms of non-stick coating and internal layout, making it marginally easier to clean after greasy or saucy meals. The accessories like air fry baskets and sheet pans in both models are dishwasher-safe, though hand-washing will help preserve their longevity. The “Flip-Up” design also helps in accessing the base of the unit for more thorough cleaning.

- User Interface: Both models include a digital display and simple dial-based controls.
- Cleaning: Both come with a removable crumb tray and easy-to-clean interiors. SP101 also includes an accessible back panel for deep cleaning.
