The Ninja Professional Plus Blender DUO with Auto-iQ is a full-size blender with a 72-ounce main pitcher and a 24-ounce personal jar and to-go lid. Its design and performance are similar to other models we've tested, like the Ninja Professional Plus Blender with Auto-iQ. It's very well-built and not very loud when it's running. Unfortunately, it doesn't have a very wide range of speed settings and only offers a few blending programs.
Our Verdict
The Ninja Professional Plus Blender DUO with Auto-iQ is decent for multi-purpose use. Its large main jar is well-suited for making big batches of crushed ice or drinks like slushies. It can also make very smooth nut butter or hummus, although using it for thick mixtures can be time-consuming. The included personal jar is ideal for making single-serve drinks like smoothies, but it doesn't make a completely smooth blend with big batches of fibrous ingredients, even after several minutes of blending. You can't use it for hot blending.
- Relatively quiet.
- Dishwasher-safe.
- Superb for single-serve smoothies.
- Makes smooth nut butter.
- Slow to blend big batches of fibrous ingredients.
- Small selection of speed settings and blending programs.
- Difficult to clean by hand.
- Can't hot blend.
The Ninja Professional Plus Blender DUO with Auto-iQ is excellent for single-serve smoothies. It comes with a personal jar that's very well-suited for making smoothies or shakes for one. There's a matching to-go lid so you can take your drink with you to-go. The personal jar and blade assembly are dishwasher-safe, and it's not very loud for a full-size blender, which is nice if you like a smoothie in the morning.

The Ninja Professional Plus Blender DUO with Auto-iQ is good for making multiple smoothie servings. It has a large capacity and easily crushes ice, so ice cubes or frozen fruit chunks are no problem. It can make a well-blended smoothie with ingredients like kale and blueberries, but it'll be slightly grainy, and you have to blend for a long time to get the best results. The main jar is tricky to clean by hand, but on the plus side, it's dishwasher-safe.

You can't use the Ninja Professional Plus Blender DUO with Auto-iQ for hot blending, so if you like a lot of pureed soups and sauces, it's probably not the blender for you. It's slow to blend big batches of fibrous ingredients and makes a slightly grainy blend with ingredients like broccoli and kale. That said, it has a big 72-ounce capacity.

However, you can't use it for hot blending, and it takes a long time to process fibrous ingredients in its main jar, so it's not ideal for big batches of fruit smoothies or vegetable soup.

Popular Blender Comparisons
This blender has a similar design and performance to other Ninja blenders, like the Ninja Professional Plus Blender with Auto-iQ and the Ninja Professional Plus Kitchen System with Auto-iQ. Its personal jar is fantastic for smoothies, and its main pitcher is ideal for crushing ice, but it's not the most versatile option otherwise. It's well-built and quiet, but if you want to blend hot ingredients or make smoothies for the whole family, you might prefer the Ninja Foodi Power Blender & Processor System or the nutribullet SmartSense Blender Combo.

The Ninja Professional Plus Blender DUO with Auto-iQ and the Black+Decker Quiet Blender with Cyclone Glass Jar are two glass blenders with different strengths. The Ninja is a sturdier blender and is much better for crushing ice in its main jar, so it's more suitable for big batches of slushies or blended cocktails. The Black+Decker is much better for big batches of smoothies since it does a much better job of blending fibrous ingredients in its main jar.
The main difference between the Ninja Professional Plus Blender with Auto-iQ and the Ninja Professional Plus Blender DUO with Auto-iQ is that the DUO comes with a 24-ounce personal jar, along with a matching to-go lid and blade assembly. If you use the personal jar, it's much better for making single-serve smoothies. Otherwise, they perform quite similarly.
The Ninja Professional Plus Blender DUO with Auto-iQ and the Ninja Detect Duo Power Blender Pro both come with a 72oz main jar and personal jars for smoothies. The Detect makes a smoother blend with ingredients like leafy greens, so it can make better-blended smoothies. However, the Professional is sturdier and quieter when it's running.
The Ninja Blender Duo with Auto-iQ BL642 and the Ninja Professional Plus Blender DUO with Auto-iQ are similar blenders. The BL642 comes with a 72-ounce pitcher and three personal jars for single-serve smoothies, and the DUO comes with the same 72-ounce pitcher and only one personal jar. The DUO is quieter and makes a smoother blend with big batches of fibrous ingredients. Otherwise, they perform about the same.
