- Brews multiple k-cup pod sizes: (6, 8, 10 ounce) – the most popular k-cup pod brew sizes. Use the 6 ounce brew size to achieve the strongest brew.
- Large 48 ounce water reservoir: Allows you to brew 6+ cups before having to refill, saving you time and simplifying your morning routine. The water reservoir is removable, making it easy to refill whenever you need to.
- Descaling: An important part of cleaning your keurig brewer. This process helps to remove calcium deposits, or scale, that can build up inside a coffee maker over time.
- Auto-off: An auto-off feature is easily programmed to turn off your coffee maker after it has been idle for two hours, helping to save energy.
- Simple button controls: Just insert a pod, select your desired cup brew size, and brew a great-tasting cup in under a minute.
Update: Keurig has discontinued the K55 model and replaced it with the Keurig K-Classic. They’re essentially the same machine, as both have 48 oz water reservoirs and brew 6-10 oz servings. If you were considering the K55 machine, the K-Classic is a worthy replacement.
The Coffee Maven Conclusion
Keurig’s mid-level offering, the Keurig K55 brewer offers a few add-on features compared to the base K15 model but doesn’t have many of the extras that the K250 and above offer.
In my Keurig K55 coffee maker review I mention how much I love the K55’s compatibility with most K-Cup varieties, even those not made by Keurig, and its external, 48 oz water reservoir with snap-on filter is a great convenience. However, it doesn’t feel like the sturdiest product and may not hold up for the long haul.
For first-time Keurig users taking the system for a test drive, the K55 single serve coffee maker is a great option. For experienced Keurig users looking to step up to a better model, you may want to check out the slightly more expensive K250.

Convenience is the hallmark of Keurig devices. This Keurig 55 classic series brewer is no exception:
- Lift the handle
- Insert the pod
- Select your brew size
- Enjoy your cup 60 seconds later
To that end, this Keurig K55 review gave its top grade for the model’s design and performance. I love how the water reservoir is external and detaches, making refilling and cleaning incredibly easy. There also aren’t a lot of moving parts, so I appreciate the K55’s simplicity.
Strictly in terms of design, there’s nothing significantly detrimental to note.
Small quirks: To use Keurig’s refillable K-Cups you need to pop out the single-use K-Cup holder, which sort of defeats the “lock and load” design, but honestly that feels like picking nits. From a cold start it takes around three minutes to get your coffee, but that’s not too bad.
If you’re after the signature Keurig look, this model has that. Honestly, it looks a little…cheap. There are no metallic components and it has a matte plastic look and feel. It’s “meh” appearance-wise.
Overall the construction feels very “plastic-y” and not extremely well made. In the video above, you can hear the plastic creaking as the guy inspects different components. I almost get a sense of dread as if I was living in an earthquake fault zone, just waiting for the ground to give way.
I have never used a Keurig device as my primary coffee maker, so I haven’t put them through the daily rigor that a lot of Keurig owners do. However, one of the most frequent complaints of Keurig devices is their lack of durability. With the 1 year warranty Keurig offers you’re covered for anything inside that year, but I’d be prepared to seek a replacement in Year 2. Pumps and solenoids are the primary problems for many owners.
Quality of Coffee: 8.3
I’ve never been very impressed with Keurig due to the lack of customizability — I’ve never been one for pod coffee — but if you have the a favorite single-serve pod then it’ll do a very good job of brewing that.
My biggest issue isn’t the quality of the brew but rather the quantity. A maximum size of 9.25 oz — seriously?
Ease of Cleaning: 8.8
This is a major bonus of the Keurig K55 coffee maker — cleaning is pretty easy. A big reason for that is the external, removable water tank. Several components are dishwasher safe, too. Here are some cleaning and maintenance notes on the key components of this model:
- K-Cup Pod Holder & Assembly: These can be cleaned safely in your dishwasher.
- Exit Needle: Located at the bottom of the pod holder assembly and clogs occasionally. Should this happen, a simple paperclip will suffice to unclog it.
- Water Reservoir: The reservoir and lid are not dishwasher safe, so use a sponge, soap, and water. To clean the filter at the bottom of the water reservoir, use a sink spray nozzle attachment (if you have one) or just fill with an inch or two of water and shake.
- Internal Components/Descaling: Keurig recommends that you descale your brewer every 3-6 months, depending on the mineral content of your water. You can purchase their descaling solution, or you can just run a mixture of equal parts water and vinegar as shown here.
Compatible with most K-Cup brands
Keurig 2.0 machines are notorious for their lack of compatibility both with Keurig My Cup K-Cups and non-Keurig K-Cups. That isn’t a problem with the Keurig K55 brewer.
In fact, if you’re an experienced Keurig owner, that may be the best reason to consider this model.
For first-time Keurig owners this model offers a good way to dip your toes in the water with the Keurig system, but if you’re a Keurig fanboy (or fangirl) then you may want to pony up a little extra and go with the K250, K475, or K575.
Removable water reservoir with filter
The external water reservoir makes it super easy to refill and clean your machine, and the snap-on water filter removes the need to add pre-filtered water.
No high altitude setting, temperature control, touch screen, or clock
The top-end model of the Classic Series, the K55 coffee maker is still in many ways a base model. While the K15 truly is simpler, the K250, K475, K575 offer a lot more of those “next level” features for a slightly higher price tag.
Other notable shortcomings
- Occasionally the coffee doesn’t come out in a nice stream and splatters
- Low water indicator doesn’t come on until you attempt to brew a cup (versus when the reservoir is simply low)
- While removing the drip tray is nice, it only opens up about 7″ of vertical space
How is the Keurig K55 Classic Series different than other Keurig models?
How do you choose between one of the 15,534 Keurig models available? (Slight exaggeration.) Here are a few differences that may help you decide whether the K55 is right for you:
- K55 does not have high altitude setting, temperature control, touch screen, or clock (try the K250, K475, K575)
- Maximum brew capacity of 9.25 oz (K250, K475, K575 can brew up to 30 oz. carafes)
- Difference between K45 and K55? Nothing noticeable; K45 has been discountinued and K55 is its replacement
- K55 offers wider array of K-Cup support beyond the white-rimmed Keurig 2.0 K-Cups
- Button controls on the K55; no touch screen or clock, which are available on the more advanced models
