Pros & cons
KitchenAid KF2
- ✓Cheapest way into a new super-automatic with a real steel conical burr grinder
- ✓Slim 7.7-inch-wide body squeezes onto counters most bean-to-cup machines can't
- ✓Auto steam wand with foam-density toggle makes milk texturing hands-off but adjustable
- ✓Dedicated iced coffee recipes - rare at this price in the super-automatic world
- ✗Button-and-LED interface instead of the touchscreen the pricier KF models get
- ✗Only 6 preset drinks versus 40+ on the KF8
- ✗Small 61-oz tank needs refilling daily in multi-drink households
- ✗Brand-new 2026 platform with no long-term reliability track record
KitchenAid KES6551
- ✓58 mm flat-base portafilter stands level for tamping, where the Barista Express uses a 54 mm basket
- ✓Smart Dosing grinds a measured single or double dose, and an ion generator cuts static clumping
- ✓Single-wall and double-wall baskets both in the box, so you can start pressurized and graduate
- ✓Two-year warranty, double the Barista Express's one year
- ✗Only three brew temperature settings (low, medium, high) - no 1-degree PID like the Barista Express
- ✗15 grind settings is coarse-stepped for dialing in espresso
- ✗No adjustable pre-infusion and no shot timer - you time shots yourself
- ✗$200 more than the Barista Express, which reviewers rate as the more adjustable machine
- ✗Portafilter spouts are plastic/silicone; reviewers suggest a bottomless replacement

Is the KitchenAid KF2 or the KitchenAid KES6551 easier to use day to day?
They are different classes of machine: the KitchenAid KF2 is a super-automatic that grinds, doses and brews at the touch of a button, while the KitchenAid KES6551 is a semi-automatic you dose, tamp and time yourself.

The KitchenAid KF2 steams and textures milk automatically, while the KitchenAid KES6551 uses a manual steam wand you texture milk with yourself.
