Each brand prioritizes different features, so you’ll want to think carefully about your blending needs when making a purchase. That’s why we entrusted Millie Fender, our appliance expert and Head of Reviews, to put two of the biggest names in blending to the test. She gave the Nutribullet Pro 900 Series Blender and KitchenAid K400 various tasks and found they suit quite different kitchens.
Whether you’re a solo shake maker or trying to efficiently feed a family, we’ve got hands-on experience with these appliances. From soups and smoothies to ice cones and cocktails, we’ve evaluated these blenders to find the right one for you.
KitchenAid vs NutriBullet - Overall
Sturdy and stylish, KitchenAid and NutriBullet seem to have it all: they look the part, work effortlessly, and are straightforward to use. Both companies offer a range of colors, to match any kitchen décor. They’re both easy to use and powerful when it comes to blending and pulsing.
From the get-go, the NutriBullet is a great blender for smoothies. With one, standard, 900-watt power output, kale stems and frozen blueberry skins whizz into a smooth mix. For more varied tasks, the KitchenAid steps into the spotlight. Its 1200 watts of power and five speed settings are betting for blending ice, cauliflower, and vegetables for soup.
It's clear that the NutriBullet suits smaller households; it comes with 18 and 32 ounce cups. The KitchenAid has a much larger 56 ounce capacity pitcher.

KitchenAid vs NutriBullet - which is better at making smoothies?
The ultimate test for any blender is a smoothie. The KitchenAid K400 blender can blend frozen fruit, leafy greens, and oats in under a minute, with only a few of the toughest oats left behind. With a special, timed smoothie setting, it's a hands-off blending experience: just choose the setting and the blender does the rest. If you want a little more control, the variable dial means that you can manually adjust the thickness and texture of your smoothie.
The NutriBullet slots in, pushes down, twists, and blends away. Even with kale stems, this gave a wonderfully smooth result, powering through the tough bits which escaped the KitchenAid. The smaller cup capacity targets single users, who can slot the removable handle around the blender for a grab-and-go container.
For batch smoothies, use the KitchenAid. If you’re making them for yourself, or one other person, you’d be better off using the NutriBullet for an out-of-this world texture.
KitchenAid vs NutriBullet - which is better at making soups?
There’s no battle here. NutriBullet warns against using hot contents inside the blender. The KitchenAid's plastic jug, although a little tough to open, was a success when making soups. Our expert, Millie, gave the KitchenAid fibrous ginger and tough vegetable skins to blend. The result? Enough smooth soup to serve four to six people. Only a few small fibers and skin pieces weren't blended.
If soup is going to be your speciality, it’s worth reading Millie's review of the Vitamix A3500 Ascent Series Smart Blender, which is better than either of these for making soup.
KitchenAid vs NutriBullet - which is better at crushing ice?
With a special ice-crushing setting, the KitchenAid blended ice into a fine and even texture in under 30 seconds, perfect for snow cones. However, bear in mind that it’s very noisy, though this is to be expected. On the other hand, the NutriBullet can chop through ice, but is less consistent and might need a little shake to redistribute the shards.
KitchenAid vs Nutribullet - which is easiest to clean?
Neither are particularly difficult to clean. Adding warm water and dish soap with a few pulses effortlessly clears the worst of the mess. Both the lid and jug of the KitchenAid can go in the dishwasher too, but the NutriBullet’s blades cannot. If you want the most effortless clean, go for the KitchenAid.
KitchenAid vs NutriBullet - which looks best?
Smart and sleek, both blenders are well-designed for a variety of interior styles. In a wide range of colors, both NutriBullet and KitchenAid can be styled for subtle color synergy or stand-out kitchen statements. KitchenAid’s range of kitchen appliances offer the opportunity for some kitchen coordination between your blender and mixer. The sheer 12 pound weight of the KitchenAid means that it’s probably best to leave it on the countertop or in lower cabinets. The NutriBullet can be compactly stored, but is equally discrete on a countertop.
KitchenAid vs Nutribullet - which should I buy?
It depends on your circumstance and lifestyle. For versatility and larger quantities, the KitchenAid K400 is a reliable blender. With five power settings, a large jug, and more power, it’s designed with busy homes in mind. Bear in mind that the nature of a versatile appliance is that you inevitably compromise on specific features: blenders with thinner blades will suit soups and smoothies, but struggle more with crushing ice.
If you're a solo smoothie fanatic, the NutriBullet Pro 900 Series is for you. The finer blend is a real gift for those who appreciate a smooth texture, especially if you want to start making your own non-dairy milks and cold blends. We love the easy-to-use handle which converts your blender into a cup to take with you on the go.
Are these the best blenders KitchenAid and NutriBullet make?
We chose these two blenders because they are a fair comparison. We think that they are the best on the market from each brand, but, if you want to save a bit more, you can buy alternate versions. For example the KitchenAid K190 has less power, but comes with a much smaller price tag.
What is the best blender?
If you asked our expert, Millie, for her overall favourite, she would pick a different model entirely: the Vitamix A3500 Ascent Series Smart Blender. Both the NutriBullet and KitchenAid are great options for different reasons, but in our roundup, this one pipped them both to first place.
How to choose a blender
You’ll want to think about what kind of blending you’d be doing. Whether your speciality is soups and smoothies, crushed ice, or cauliflower rice, the blades and size of your blender will vary.
Depending on what you’ll be blending, you’ll want to think about power. Frozen fruits, tough vegetables, and ice need more powerful motors for a satisfying result.
Some blenders will have automatic programs, so that you don’t need to do much guessing when blending.
Some people like to have manual control if they plan on blending different ingredients or are looking for some variety. For example, if you prefer your soups a little thicker.
These are a luxury rather than a necessity. The more you pay, the more versatile. For example, some blenders can heat your ingredients, so that raw ingredients can be piping hot soup in a few minutes.
This is one to watch. If you’re a large household, you’ll want a large jug so that you don’t end up having to blend in batches. If you’ll be blending for one, you’re better off with a smaller jug. The NutriBullet has accessories to suit a single drinker, as the removable holder encourages you to take it on the move.

Do I want a glass or a plastic pitcher?
Most blenders are made from plastic. It works well, is less likely to break if dropped and will weigh a lot less. People still make glass pitchers, because they are harder to scratch when crushing ice, for example. Or, if you’re using ingredients that will stain, glass is less likely to take on the colour.
Which blender is the quietest?
Blending is a noisy activity. Noise tends to correlate to what you’re blending and the power of the blender. If you end up going for a smaller, quieter appliance, be ready to compromise on results.
What appliances come with the NutriBullet?
The NutriBullet K900 Pro comes with the essentials: a power base, extractor blade, cup and lip ring (for sealing your blender). It’ll also have a larger cup, flip-top lid and stay-fresh lid.
What appliances come with the KitchenAid?
The KitchenAid K400 comes with a jar, lid and cap. Simple as that. You can buy different sized jugs, a citrus press, and a bottle from the KitchenAid website.

Can you make muffins in a blender? Yes – here's how
It sounds strange but you can make muffins in a blender. If you don't have a stand mixer, hand mixer, or food processor, a blender is the next best thing.
