Shopping for a KitchenAid blender in 2026 is simpler than it used to be. Amazon’s KitchenAid lineup now comes down to two full-size models worth a look: the K400 Variable Speed Blender and the newer Pure Power Blender. This guide walks through what each one does, how they compare side by side, and when it makes more sense to step up to a Vitamix instead. We haven’t run our own lab tests on these machines, so everything below is based on the manufacturer specs, the Amazon listings and the design of each blender.
Quick answer: which KitchenAid blender to buy
- Buy the KitchenAid K400 if you want the best all-round KitchenAid countertop blender: a variable speed dial, three presets, a tamper and a self-clean cycle in a sturdy, good-looking base.
- Buy the KitchenAid Pure Power if you want a bigger 68 oz jar plus two 16 oz personal jars in the box, and you mostly make smoothies and shakes.
- Look at a Vitamix 5200 or E310 if you blend every day, want hot soup straight from the jar, or care most about a long warranty. Our Vitamix models compared guide breaks down that lineup.
KitchenAid K400 Variable Speed Blender (KSB4028)
The K400 is KitchenAid’s flagship countertop blender on Amazon. KitchenAid describes a “3 part blending system”: a ribbed jar shaped to create a vortex, an asymmetric blade, and what it calls Intelli-Speed Motor Control, which senses what is in the jar and holds the speed steady as the load changes. The listing rates the motor at 1200 watts.
Controls. You get a five-speed variable dial for manual blending plus three preset programs: Ice Crush, Icy Drink and Smoothie. Presets are handy for one-touch smoothies in the morning, and the dial lets you pull back for chunky salsa or push up for a smooth purée.
Jar and tamper. The K400 ships with a 56 oz BPA-free jar, a lid and a tamper. The tamper matters more than it sounds: thick blends like frozen fruit bowls or nut butter tend to cavitate (spin an air pocket around the blade), and a tamper lets you push the food back down without stopping the motor.
Accessories. KitchenAid sells a 6 oz small-batch jar (KSB2040BBB) and a 16 oz personal jar pack (KSB2030PJB) separately, so you can add single-serve cups later if you need them.
Cleaning. There’s a self-clean cycle: add warm water and a drop of soap and let it run.
Who it’s for: people who want a premium-feeling blender that matches other KitchenAid appliances, make smoothies and frozen drinks most days, and want more control than a basic personal blender. The K400 is also sold in several colors, so check the listing for the finish you want.
KitchenAid Pure Power Blender (68 oz jar + two 16 oz cups)
The Pure Power (model KSB2078) is the newer, more family-sized option. Its headline number is “1700 watts peak power,” but KitchenAid’s own footnote on the listing explains that this is a laboratory measurement of peak input wattage, not the power delivered at the blade, and that the blender is UL rated at 1200 watts. That’s an honest note and worth keeping in mind when you compare wattage claims across brands.
What’s in the box: a 68 oz BPA-free plastic jar with lid, two 16 oz personal blending jars with travel lids, and the blade assembly. That makes it the better pick if you want to blend a big batch for the family one day and a single to-go smoothie the next, without buying extras.
Controls: a precision speed knob for anything from chunky salsa to smooth tomato soup, plus a one-touch Smoothie Cycle. KitchenAid says the jar can handle hot or cold recipes, such as roasted tomatoes straight from the oven, but always vent the lid and start slow with hot liquids.
Who it’s for: households that want capacity and personal cups in one box and don’t need a tamper or a lot of preset programs.
K400 vs Pure Power: side-by-side
| KitchenAid K400 (KSB4028) | KitchenAid Pure Power (KSB2078) | |
|---|---|---|
| Power (per listing) | 1200 watts | 1700 watts peak (KitchenAid notes UL rating of 1200 watts) |
| Main jar | 56 oz BPA-free jar | 68 oz BPA-free plastic jar |
| Personal cups | Sold separately (16 oz expansion pack) | Two 16 oz personal jars included |
| Controls | 5-speed variable dial + 3 presets (Ice Crush, Icy Drink, Smoothie) | Precision speed knob + Smoothie Cycle |
| Tamper | Included | Not listed |
| Cleaning | Self-clean cycle | Jar and parts; check manual for dishwasher guidance |
| Footprint (K400 listing) | About 9 x 7.6 x 15.8 in | See listing |
| Warranty | Check the listing / KitchenAid | Check the listing / KitchenAid |
| Tier | Mid-premium | Mid-range |
The short version: the K400 is the more refined machine (tamper, three presets, self-clean, variable speed with motor sensing), while the Pure Power gives you more jar capacity and personal cups out of the box. If you often make thick frozen blends, the K400’s tamper is the deciding feature. If you mostly make thin smoothies and want grab-and-go cups, the Pure Power is the practical choice.
KitchenAid K400 vs Vitamix 5200 / E310: when the Vitamix is worth it
The K400 is often compared with Vitamix because both are premium countertop blenders with tampers and self-clean cycles. They’re built for slightly different buyers, though.
| KitchenAid K400 | Vitamix 5200 | Vitamix E310 | |
|---|---|---|---|
| Jar | 56 oz | 64 oz classic container | 48 oz |
| Speeds / programs | 5 speeds + 3 presets | 10 speeds + High switch | 10 speeds + Pulse |
| Tamper | Yes | Yes | Yes |
| Self-clean | Yes | Yes (warm water + soap) | Yes |
| Warranty (per listing) | Check listing | 7-year limited | Check listing |
| Best for | Smoothies, icy drinks, countertop looks | Daily heavy use, hot soups by friction, nut butters | Vitamix performance in a smaller jar |
Choose the Vitamix 5200 if you blend heavily every day, want to make hot soup directly in the container (Vitamix’s blades heat soup through friction at high speed), or want the reassurance of the 7-year limited warranty that Vitamix lists for the 5200. Its tall 64 oz container is great for big batches.
Choose the Vitamix E310 Explorian if you want Vitamix performance in a more compact package. It has 10 speeds, a Pulse feature, a 48 oz container and the same self-cleaning approach, and it usually sits at the lower end of Vitamix’s range.
Stick with the K400 if you want presets (the 5200 and E310 are manual-only), prefer a shorter, more compact base, or simply like the KitchenAid look on your counter. For everyday smoothies and icy drinks, it covers what most home cooks need.

Which KitchenAid fits your kitchen?
Think about what you’ll blend most often. For daily smoothies with frozen fruit, the K400’s presets and tamper make life easier. For a family that wants big batches and grab-and-go cups, the Pure Power’s 68 oz jar and two personal jars are the better value. Also measure the space under your cabinets: the K400 listing gives a height of about 15.8 inches with the jar on, which fits under most standard cabinets.
What about the KitchenAid K150?
The K150 used to be KitchenAid’s popular entry-level model. At the time of writing it’s discontinued or unavailable from Amazon’s main listing, so we don’t recommend chasing it through third-party sellers. If you want a KitchenAid at a lower tier, the Pure Power is the current alternative. If you want the best KitchenAid blender overall, go with the K400.
KitchenAid hand blenders
If you mostly blend soups in the pot, purée baby food or make single smoothies, a hand (immersion) blender may suit you better than a countertop model. KitchenAid makes both corded and cordless versions, including the KitchenAid Go cordless hand blender. We compare the best options in our best immersion blenders guide.
FAQ
Is the K400 available with a glass jar?
KitchenAid has sold glass-jar versions of its blenders in the past, but the K400 listing we recommend (KSB4028) comes with a 56 oz BPA-free plastic jar. If a glass jar matters to you, check the exact model number and “Included Components” on the listing before you buy.
Is KitchenAid as good as Vitamix?
For smoothies, frozen drinks and everyday blending, the K400 is a capable premium blender. Vitamix is built for heavier daily use, hot soups made by friction, and very fine textures like nut butters, and it backs the 5200 with a longer warranty. If you blend once a day or less, the KitchenAid is usually enough.
Are KitchenAid blender jars dishwasher safe?
The K400 has a self-clean cycle that handles most everyday cleanup. For dishwasher guidance on the jar, lid and blade assembly, follow the use-and-care manual for your exact model, since recommendations differ between models.
Which KitchenAid blender is the quietest?
KitchenAid doesn’t publish decibel ratings for these models, so we can’t rank them on noise. Any full-size blender is loud at top speed.
Bottom line
The KitchenAid K400 is the KitchenAid blender to buy for most people: variable speed, presets, a tamper and self-clean in a well-built base. Pick the Pure Power if you want the bigger jar and personal cups included. If you want hot soups and a long warranty, step up to a Vitamix 5200.
