The Ninja BN701 and Ninja BN751 are two of Ninja’s most powerful countertop blenders. They both deliver strong performance with 1400-watt motors, large blending capacities, and Auto-iQ technology designed to simplify blending tasks. On the surface, they may seem nearly identical, but when you look closer, there are clear distinctions in control, functionality, and use case.

Design and Build
Both the BN701 and BN751 have a nearly identical look and feel. They feature a black base, BPA-free plastic construction, and Ninja’s signature Total Crushing blade system that uses stacked, multi-level blades to tear through ice and tough ingredients. The base footprint is similar, and both models use a 72-ounce pitcher that is dishwasher safe.
What sets the BN751 apart is a slightly enhanced interface that includes a dedicated manual mode. This gives you more precise control over the blending process — something that the BN701 lacks. While this may not seem like a big deal for basic smoothies, it becomes crucial if you frequently prepare items like soups, sauces, or salsas, where texture control matters.
Control and Programs
BN701
The BN701 is built for users who want pre-programmed simplicity. It comes with three Auto-iQ buttons:
- Smoothie
- Ice Crush
- Ice Cream
Each program is timed and uses intelligent pulsing patterns. This makes it incredibly easy to press one button and walk away. However, if the texture isn’t quite right, you can’t manually adjust mid-blend.
BN751
The BN751 offers the same Auto-iQ programs for Smoothie and Ice Crush, but instead of a third recipe-specific preset, it adds a manual mode with variable speed. This is ideal for users who want to blend to their own specifications. Whether you’re pulsing ingredients for salsa or slowly mixing soup, the manual control opens up more possibilities.
This makes the BN751 a better fit for home cooks who treat their blender as a multi-use kitchen tool — not just for drinks but also for food prep.
Performance in Use
In real-world testing, both models are capable of blending tough ingredients like frozen fruit, leafy greens, and ice cubes. The 1400-watt motors provide plenty of power, and the blade system performs consistently across a variety of recipes.
The difference is mostly felt when you want more nuanced control. For example, with the BN751 you can:
- Pulse just enough to get chunky salsa
- Blend slowly to emulsify salad dressings
- Adjust speed for delicate mixes without overprocessing
If all you’re doing is smoothies or shakes, this added control may not be necessary. But if you want your blender to do more — like prep soups, sauces, or custom recipes — the BN751 starts to stand out.
Cleaning and Maintenance
Both the BN701 and BN751 are easy to clean. The pitcher, blades, and lid are all dishwasher-safe, and daily cleaning can be as simple as blending warm water with a drop of dish soap for a few seconds. The blades are removable for deep cleaning, although caution should be used when handling them due to their sharpness.
The BN751’s lid has a tighter seal and a slightly upgraded locking mechanism, which may improve containment during high-speed blending — particularly helpful with hot or thin liquids.
Noise and Usability
Because both units run on the same motor, noise levels are nearly identical. Expect moderate to loud sound during high-speed blending. They’re quieter than traditional commercial blenders but still noticeable in a quiet kitchen.
Both models feature suction cup feet for added stability and use the same locking pitcher mechanism to ensure safety before starting.
The control panel layout is intuitive on both models, but the BN751’s inclusion of a manual button adds one more layer of functionality for those who want more than just push-and-go blending.
Which One Should You Choose?
Choose the Ninja BN701 if:
- You want a simple, preset-driven blender that works without needing manual adjustments
- You primarily make smoothies, protein shakes, or frozen drinks
- You prefer minimal interface complexity and quick prep
Choose the Ninja BN751 if:
- You want to blend more than just drinks — like soups, sauces, and dips
- You prefer having control over blending speed and duration
- You value having both preset automation and hands-on versatility
Conclusion
The Ninja BN701 and BN751 are both high-performing blenders with identical power and core design. The real difference lies in the level of control each offers. The BN701 is ideal for anyone who wants fast, hands-free results for common recipes. The BN751 is built for more involved users who want a bit more flexibility and creative freedom in the kitchen.
If you’re looking for a blender that can do more than smoothies — especially if you cook or prep often — the BN751 will give you more tools in one machine. But if you’re mainly blending drinks and want ease of use, the BN701 is still a solid, reliable choice.
