Overview
The KitchenAid K400 (KSB4027) is a 56 ounce variable speed blender with Intelli-Speed motor control, three preset programs and a self-clean cycle, sized to sit next to a KitchenAid stand mixer.
Several owners who came from a Vitamix say this matches it for blending power and consistency while being easier to clean thanks to the jar shape. The tradeoffs owners raise are volume during operation and at least one report of a loose exterior trim band, so fit and finish isn't described as consistent across every unit.
- 56 ounce jar with 3 preset programs: ice crush, icy drink, smoothie
- Intelli-Speed motor control auto-adjusts to jar contents
- Asymmetric blade cuts at four angles
- Self-clean cycle with water and soap
Who it's for
People making daily smoothies or crushed-ice drinks who want serious power without a full-size Vitamix footprint. Not for anyone needing a quiet blender or expecting flawless cosmetic finish on every unit.
Pros and cons
- Blending power and consistency compared favorably to a Vitamix by owners
- Self-clean cycle works with just water and soap
- Compact footprint next to other KitchenAid countertop appliances
- Loud during operation
- At least one report of a loose exterior trim band
- Manual control layout takes some owners a moment to learn
Performance notes
The Intelli-Speed motor senses what's in the jar and holds the selected speed, while the asymmetric blade cuts at four distinct angles and the ribbed jar drives a vortex to pull ingredients down into it. A soft start ramps the motor up gradually to limit splatter, and the self-clean cycle runs on water plus a drop of soap.
