KitchenAid Fully Automatic Espresso Machine KF6: two-minute review

The KitchenAid KF6 is a fully automatic bean-to-cup coffee machine, and it does its main job exceptionally well: brewing a delicious, rich espresso with the best crema I’ve ever seen.

It offers a wide menu of espresso drinks, each of which can be customized and saved to a custom profile. In addition, it includes an automatic milk-frothing system for options including cappuccinos, caffe lattes, and macchiatos. Unlike the higher-end KitchenAid Fully Automatic Espresso Machine KF8 we reviewed in 2024, there’s no separate profile for plant-based milk.

In addition, it's one of the quietest coffee machines we’ve tested here at TechRadar, with a pump that’s barely any louder than your refrigerator. The only significant noise happens for a moment during grinding and milk frothing, and it’s over in a second or two.

Thoughtful touches include a brew group that purges itself automatically between drinks to ensure you always have fresh beans ground to the correct size (like a barista would purge their grinder); a chute so you can make an occasional drink using a different bean to the one in the hopper; and a comprehensive set of cleaning functions that make maintaining the machine as simple as using it.

It’s also less expensive than you might expect. Fully automatic bean-to-cup coffee makers are never going to be cheap, but the KF6 costs far less than the KF8, with only a few compromises – and it’s often available at a discount, too.

KitchenAid Fully Automatic Espresso Machine KF6: price and availability

• List price $1,199.99 / £1,299 / AU$1,799
• Far less expensive than KitchenAid KF8
• Often available at a discount

The KitchenAid KF6 launched in 2024, and is available to buy directly from KitchenAid, or from third-party retailers. It has a list price of $1,199.99 / £1,299 / AU$1,799, but you can often find it more cheaply. For example, at the time of writing it’s discounted to $999.99 in the US and AU$1,599 in Australia for Valentine’s Day.

It certainly isn't cheap, but fully automatic bean-to-cup machines never are due to their complexity; plus the KF6 delivers plenty for the money. It's far less expensive than its higher-end sibling, the KF8, which has a list price of $1,999.99 / £1,899 / AU$2,599. While the KF6 makes a few compromises to keep the cost down, it remains an exceptional coffee maker; in my opinion, it's much better value than its big brother.

KitchenAid Fully Automatic Espresso Machine KF6: specifications

KitchenAid Fully Automatic Espresso Machine KF6: design

• Sleek and modern look
• Takes whole beans and grounds
• Automatic milk texturizing system

The KitchenAid Fully Automatic Espresso Machine KF6 is a sleek, modern-looking coffee maker, with a matt finish and brushed stainless steel accents. It's available in three colorways: stainless steel, cast iron black, and porcelain white (the latter of which launched in January 2025).

Its screen measures 2.4 inches diagonally (6cm), which is smaller than that of the KF8, but it’s still bright and clear, with plenty of space for reviewing and tweaking your drink settings. You operate the machine using a set of touch-sensitive buttons positioned beside the display, and the power button is located discreetly on the left-hand side of the case.

The bean hopper is accessed via a hatch on the top, and has a central dial that twists to lock and unlock it. The hatch has a rubber seal to help keep your beans fresh. Next to the hopper, you’ll find a small chute where you can insert a scoop of pre-ground coffee if you want to use a different bean from time to time. This is particularly handy for those who prefer to switch to decaf in the evening; the machine will detect if the chute has been opened and automatically offer you the option of using ground coffee rather than beans when you next select a drink (a thoughtful touch). The KF6 arrives with a scoop to make this easier.

The KF6's water tank has a capacity of 2.3 quarts / 2.2 liters, which is the same as the other espresso machines in KitchenAid’s fully automatic series, and has a folding handle that makes it easier to carry it to the sink. You also get a water-testing strip, so you can decide which water hardness setting to choose, and a water filter that screws into the bottom of the tank. Additional filters are available to purchase directly from KitchenAid, or from Amazon.

The dispenser slides smoothly up and down to accommodate different-sized cups, and can dispense coffee and milk into one or two cups.The drip-tray beneath slides out smoothly when lifted slightly, and contains a removable bin where used coffee pucks are deposited. The tray has a spout shape at the back to avoid mess when emptying and rinsing.

The KitchenAid KF6 has an automatic milk-frothing system, but unlike the KF7 and KF8, it doesn’t come with a dedicated container. Instead, you just place the end of the tube into your own jug or cup of milk. The results are the same; the only difference in practise is that you can’t pop the closed container into the fridge between uses. However, unlike the higher-end KF8, the KF6 doesn’t have a separate profile for plant-based milk. You can still use it to heat and texturize oat, soy, or almond milk, but the system is optimized for dairy.

The only downside to the design is that I noticed a few small scratches on the stainless steel drip-tray after testing, which must have been caused by the bottom of the glass and ceramic cups I was using. They were noticeable only when observing up-close, however; you’d never see them in ordinary use. I was just a little surprised it happened so quickly.

KitchenAid Fully Automatic Espresso Machine KF6: performance

• Makes exceptionally good espresso with thick crema
• Good choice of customizable drink presets
• No profile for plant-based milks

The KitchenAid KF6 is very simple to use and, most importantly, makes a gorgeous espresso – rich and delicious, and with exceptionally thick crema that even earned praise from team coffee aficionado and reviews editor Josh Russell, who noted that his manual espresso machine couldn’t produce similar results.

The KF6 doesn’t have quite such an extensive menu of presets as the KF8, but still offers plenty of choice. There’s scope for customizing the strength, temperature, volume, and body of each drink, too. The options offered by the KF6 are:

• Espresso
• Cappuccino
• Caffe latte
• Macchiato
• Latte macchiato
• Americano
• Coffee

The KF6 can also dispense hot water and warm milk. However, unlike the higher-end KF8, it doesn’t offer a cooler water option for brewing green tea, or foamed milk without coffee for a babyccino.

When I tested the KitchenAid KF8 in 2024, I found that the default settings for a cappuccino and latte didn’t produce as much milk foam as I like, and it was the same with the KF6. Thankfully, both machines let me adjust the volume of the drink to add more milk, which resulted in thicker foam. It’s easy to play around with the options before making your espresso drinks, and once you’ve set your preferences, you can save them to one of four custom user profiles. The KF6 supports six profiles, but four will be plenty for most households.

The KF6 is Quiet Mark certified, meaning it has been designed with noise reduction in mind. It’s definitely quieter than most of the best espresso machines I’ve tested. It reached 75db for a second or two while foaming milk (similar to a vacuum cleaner) and 66dB while grinding coffee (about the noise of a normal conversation), but averaged a mere 44dB while the pump was in operation (a very gentle hum).

Sometimes, the convenience of a bean-to-cup coffee machine is offset by the hassle of maintaining it, but this isn't the case here. All of KitchenAid’s fully automatic espresso machines offer a great selection of cleaning and maintenance functions, and you’ll be prompted when it’s time to run each one.

After each milk-based drink, you’ll be advised to run the "easy milk rinsing" program, which uses water from the tank to flush the lines. To keep things hygienic in the longer term, the "deep milk cleaning" function uses a cleaning solution to give everything a good wash and remove proteins and bacteria.

There’s a quick option for rinsing the brew unit, plus a deep-cleaning mode that requires you to remove the brewing unit and insert a cleaning tablet to remove any build-up of oils that could start to impact the taste of your drinks.

The KF8 also offers a function that purges all coffee from the hopper and brew unit (ideal if you want to switch to a different bean), and one that evaporates all water from the system (great, if you won’t be using the machine for a while or need to transport it). You may need to use a cloth to absorb a little leftover water from the dispenser once it’s done, but the evaporation system works very well.

Generally speaking, I found the differences between the KF6 and the KF8 to be quite small. Although there are fewer drink options, the ones I use frequently are still available (and customizable). The absence of a special container for milk barely affects the experience at all, and the smaller screen is still ample for displaying your various options.

The only thing I really missed was the plant milk option from the KF8, which yielded particularly silky micro-foam when used with almond milk. If you rarely use plant milk, it’s well worth considering opting for the KF6 instead – the experience is just as good; it handles dairy equally well; and it brews an exceptional coffee.

KitchenAid Fully Automatic Espresso Machine KF6: how I tested

I tested the KitchenAid Fully Automatic Espresso Machine KF6 using fresh coffee beans from local coffee shop, Mokoko, and chilled whole milk. I used each of the machine’s preset drink options, experimenting with the volume, temperature, strength, and body settings, creating a custom user profile.

I also ran all of the machine’s cleaning programs, including the intensive profiles for cleaning the milk system and brewing group, and evaporating water from the whole system. For more details, see how we test, review, and rate on TechRadar.
