Overview
Blue Velvet is the finish on this KitchenAid K400 countertop blender, built around a ribbed jar, an asymmetric blade, and Intelli-Speed motor control that senses contents and adjusts speed automatically. A tamper ships with it for pushing thick ingredients into the blade.
The Intelli-Speed system and Soft Start feature target two common blender complaints, uneven blending and splatter at startup, by sensing contents and ramping speed up gradually. It also includes a self-clean cycle that runs with just water and a drop of soap.
- Vortex-shaped ribbed jar with asymmetric blade
- Intelli-Speed Motor Control senses contents automatically
- Variable speed dial plus 3 preset programs
- Self-clean cycle and Soft Start anti-splatter feature
Who it's for
Home cooks who want variable speed control plus preset programs for common tasks like smoothies or crushed ice, without stepping up to a commercial-grade blender.
Pros and cons
- Variable speed dial plus 3 preset programs for ice, icy drinks, and smoothies
- Automatic speed sensing via Intelli-Speed Motor Control
- Self-clean cycle with just water and soap
Performance notes
The vortex-shaped jar combined with the asymmetric blade and Intelli-Speed Motor Control is meant to pull ingredients like kale and almonds through the blade consistently rather than requiring manual speed changes mid-blend. The Soft Start feature ramps the motor up gradually to avoid splatter when starting.
