I wanted one blender that could handle family drinks and quick single drinks. I tested the Ninja BN751 Professional Plus DUO to see how well it fits that need. It has a 1,400-watt motor, a 72-ounce pitcher, and two 24-ounce cups. My quick take: it is a great fit for busy homes that want both large and small blends.
Ninja Duo Auto IQ Reviews
The Ninja BN751 Professional Plus DUO is a full-size blender with a simple goal. It lets me make a large batch or switch to a personal cup when I only need one drink.
The main pitcher holds 72 ounces. The max liquid fill is 64 ounces. That gives me enough room for a family-size smoothie or a few cold drinks in one batch.
The motor is rated at 1,400 peak watts. That gives the blender plenty of force for ice and frozen fruit. I found this to be one of its best traits.
The three Auto-iQ programs are another big part of the design. I can choose a preset for smoothies, frozen drinks, or nutrient extraction. The blender then runs the set pattern for me.
I like this setup because I do not need to stand next to the blender and watch the time. I can press a button and work on something else in the kitchen.
The DUO setup also includes two 24-ounce cups. Each cup has a spout lid, so I can make a drink and take it with me. This is handy on busy mornings.
The cups also change how I use the blender. I do not need the large pitcher every time. For one person, a small cup can be a better match.
The main pitcher uses a stacked blade system. The blades are made to crush hard foods and ice. This helps when I make frozen drinks or cold smoothies.
The parts are BPA-free, and the removable parts are dishwasher safe. I like this after making thick drinks because I can spend less time at the sink.
The blender is about 17.5 inches tall and weighs about 8.44 pounds. It is not a small machine, so I would check my cabinet space before buying.
It uses 120-volt power, which fits a normal US home outlet. That makes it simple for American kitchens.
One thing I would not expect from this model is hot blending. I would not use it for hot soup. This blender is better suited to cold food and drinks.
I also think the controls are best for people who like simple choices. There are three speeds and the Auto-iQ programs. If I wanted very fine manual control, I would look at a different model.
What I Like
- Two ways to blend: I can use the big pitcher for a group or a 24-ounce cup for one drink.
- Strong ice work: The stacked blades make this a good choice for frozen drinks and crushed ice.
- Auto-iQ programs: I can start a preset without guessing how long to blend.
- Large main pitcher: The 72-ounce size is useful when I make drinks for family or friends.
- To-go cups: The two personal cups make morning smoothies easy to take with me.
What Could Be Better
- Large counter size: The 17.5-inch height may be too much for some kitchen spaces.
- Sharp blade unit: I need to be careful when cleaning around the blades.
- No hot blending: I would choose another blender if hot soup is a key part of my routine.
My Personal Experience with Ninja BN751 Professional Plus DUO
My favorite part of this blender is the choice of pitcher size. On a family morning, I can use the large jar and make enough for everyone. I do not need to run the blender more than once.
When I am alone, I use the smaller cup instead. The 24-ounce size feels much more natural for one smoothie. I also like that I can put on the spout lid and take the drink with me.
Frozen fruit is another area where this blender fits my routine. I can add frozen berries, banana, and liquid without needing to thaw everything first. The strong motor gives the blend a good start.
I also use ice when I want a cold drink. The stacked blade design is made for hard foods, so ice is a natural job for this machine.
The Auto-iQ buttons are useful when I am busy. I can pick the setting I need and let the blender do its timed work. This saves me from standing there and checking the blend.
For a work-from-home morning, the personal cup is handy. I can make one smoothie before work and take it to my desk. I do not have to dirty the large pitcher for one small drink.
For weekends with guests, the big pitcher makes more sense. I can make a larger drink batch in one go. That is where the 72-ounce size really earns its space.
I also like the nutrient extraction program for certain drinks. It gives me a simple way to run a preset without changing the speed by hand. I still choose my ingredients with care because a preset cannot fix a poor recipe.
The cleanup feels easier when I use the dishwasher. The removable parts are dishwasher safe, so I do not have to wash every piece by hand after each drink.
The blade needs more care than the rest of the set. I would not reach into the pitcher without thinking about the blade position. A brush is a safer way to deal with food stuck near the blades.
The size is the one thing I would plan for before buying. At about 17.5 inches tall, it may not slide under every cabinet. I would measure the space first.
Noise is also something I would expect from a strong blender. It is not a quiet machine, especially when crushing hard foods. I would avoid running it right beside someone who is on a call.
For me, the biggest value is the DUO setup. I get a large pitcher for family use and two smaller cups for quick drinks. That makes it more useful across different parts of my day.
Comparing With Other Brands
I would compare this Ninja with brands such as Vitamix, NutriBullet, and other Ninja models. The main question for me is not just power. I would also look at cup size, preset options, cleanup, and how often I make large batches.
Ninja vs Other Brands: Quick Comparison
For comfort, the Ninja is easy to use because the buttons are clear. The Auto-iQ programs also reduce the need to watch the blender during each blend.
For size, the Ninja has an advantage when I need a large batch. The 72-ounce pitcher gives me much more room than a small personal blender.
For single drinks, the two 24-ounce cups are a useful extra. I can make a personal smoothie without using the large jar.
For ice crushing, this model is a strong choice. The stacked blade setup is made for hard foods, and testing of similar Ninja DUO models has shown very strong ice results.
For control, I would choose a different blender if I wanted a wide range of manual speed settings. The BN751 keeps the process simple rather than giving me a huge number of choices.
For cleanup, the dishwasher-safe parts make daily use easier. I still take care with the sharp blades when I handle them.
For value, I think the DUO setup is the main reason to consider it. I get both a full-size blender and personal cups without needing two separate machines.
Recommendation
I would recommend the Ninja BN751 Professional Plus DUO to US buyers who want one blender for both family batches and personal drinks. The large pitcher is useful for groups, while the two 24-ounce cups work well for quick smoothies.
I think it is especially useful for busy homes. I can make a large batch on the weekend and use a personal cup on a workday morning.
I would do more research if my main goal were hot soup or very fine manual control. This model has a clear focus on cold drinks, frozen blends, and easy preset use.
For a US kitchen, the 120-volt power setup is a normal fit. I would also check the current Amazon price before buying because the value can change when the sale price changes.
My choice would be the BN751 when I want more than a basic full-size blender. The two cup sizes give me more ways to use it during the week.
