The KitchenAid K400 blender is great for most uses and looks and feels durable enough for even professional environments. This bulky blender comes with a big 56 oz jar so you can make large quantities of smoothies or soups at a time. It's very versatile as it can blend both cold and hot liquids, and it creates bar-quality ice quickly. Unfortunately, the jar's lid isn't the easiest to clean, but both it and the jar are dishwasher safe.

The KitchenAid K400 blender is quite similar to the KitchenAid K150 in terms of dimensions and is a bit bulky. It's not as tall as other blenders though. However, it's very heavy, so you'll likely want to store it directly on your counter as moving it around frequently can be a bit of a nuisance.

Build Quality

The KitchenAid K400 blender feels very well-built and durable. The base is made of metal and the plastic jar feels solid and well-built. Unfortunately, the handle grip of our unit feels a bit loose and the lid feels slightly cheap, though not enough to affect the overall build quality too much.

The main jar is large enough for most uses, but isn't quite as big as some other options, like the Ninja Mega Kitchen System BL770. The jar can be put on the bottom rack of a dishwasher, allowing for easy cleaning, which is nice. Unfortunately, the lid of the jar feels a bit cheap, and the handle isn't very comfortable to grip.

The KitchenAid K400 blender has four very sharp blades. Two are pointed upwards and two are pointed downwards to help create a vortex. Unfortunately, they can't be removed from the jar for cleaning, but on the bright side, they're dishwasher-safe.

The jar's lid is made from a stiff plastic material. It's difficult to clean, but luckily it can be put on the top rack of a dishwasher. The center part of the lid doubles as a measuring cup, which is handy when adding ingredients mid-blend.

The power cord is long enough to reach an outlet on your counter, but you may need to use an extension if all your outlets are near the ground. Unfortunately, the blender doesn't have a compartment to hide the cable when not in use.

Despite showing options from 1-5, you can hear the motor go through 22 different speed increments as you slowly move the dial, allowing you to fine-tune the speed to a very good degree. Unfortunately, despite the max speed not being nearly as high as some other blenders, like the Vitamix Explorian E310, it still gets very loud.

The KitchenAid K400 blender is great at making almond butter. In about five minutes, it creates a spreadable butter that's fairly smooth overall but quite sticky. While the texture is a bit grainy, there aren't any large unprocessed chunks.

Foamy

The KitchenAid K400 blender is great at making smoothies. It takes about one minute to blend a thick smoothie with no chunks. That being said, smoothies made with this blender have more of a foamy consistency and aren't the smoothest. If you're looking for a full-size blender to use for smoothies, you may prefer the Vitamix ONE.

Difficult

This blender is decently easy to clean. The jar is very easy to clean after making a smoothie, though unfortunately, sticky materials like almond butter are more difficult. The lid is tough to fully clean, and the angled non-removable blades make it hard to easily clean the jar safely. Luckily, the jar and lid can both be put in the washing machine. If you want something that performs similarly but is easier to clean, check out the Vitamix Explorian E310.

Differences Between Sizes And Variants

We've reviewed the 'Black' KitchenAid K400, but it also comes in Silver, Red, Blue Velvet, and White. We expect our review to be valid for these different variants as well since only the color seems to be changing.

Compared To Other Blenders

The KitchenAid K400 is a great all-around blender that performs well regardless of what you're blending. It also supports hot blending, so you can do soups or other hot mixes, like most KitchenAid blenders we've reviewed. It's also very well-built and feels premium, but it doesn't have a very large main container like some other blenders from Vitamix or Ninja.

KitchenAid K150

The KitchenAid K400 is a better full-size blender than the KitchenAid K150. The KitchenAid K400 is more powerful, and it has a larger jar. Its build quality is better, it offers more speed settings, and it even has a self-clean program. Its smoothie performance is better too. However, the K150 is a bit more barebones in features. It has a similarly great performance to the K400 when making crushed ice or almond butter, but it can take a couple of minutes longer. It's also a bit easier to clean.

Vitamix Explorian E310

The Vitamix Explorian E310 is a better blender than the KitchenAid K400. The Vitamix produces much better smoothies and almond butter. It comes with a tamper, has a significantly better build quality, and can make snow-like crushed ice in less time. It's also easier to clean.

NutriBullet Blender Combo

The KitchenAid K400 is better than the NutriBullet Blender Combo. The KitchenAid K400 has a much better build quality and more speed settings. It can crush ice and does a much better job of making almond butter and blending smoothies. On the other hand, the NutriBullet comes with a tamper and two personal jars in addition to its main jar.

Ninja Blender Duo with Auto-iQ BL642

The Ninja Blender Duo with Auto-iQ BL642 is better for most purposes than the KitchenAid K400.

Ninja Professional Plus Blender with Auto-iQ

It does a much better job of making smoothies and almond butter, and you can use it to blend hot ingredients. However, the Ninja is a smaller personal blender that comes with a couple of personal jars with to-go lids. It also makes bar-quality crushed ice with a more uniform texture.

KitchenAid 5-Speed Hand Blender

The KitchenAid K400 and the KitchenAid 5-Speed Hand Blender have different strengths, and you may prefer either one depending on your needs. Both models can blend hot ingredients, but the K400 is a full-size blender that makes much smoother, more spreadable almond butter and crushed ice with a better texture. It also takes less time to make a smoothie. On the other hand, the 5-Speed Hand Blender is an immersion blender that you can use to blend hot ingredients directly in a pot or pan. It also comes with a variety of extra blades and accessories, including food processing and whisk attachments, although we don't test those currently.
