Touch Button Control – Provides User-friendliness

Descaling Feature – Easy Cleaning of Machine

This feature allows you to clean your device with a lot of ease as it removes calcium deposits through and through that build up inside over a period of time. Self-cleaning is a very good feature of this device.

Large Water Reservoir – No Need to Keep Refilling

This coffee maker has a removable large size water reservoir with a capacity of 48oz. This will give you more than 6 cups of proper brewed coffee.

Removable Tray – Accommodates Your Travel Mug

Removing the drip tray makes it possible to place larger mugs or travel mugs – this allows coffee on-the-go as most people take their beverage along to work.

Keurig K55 Design – Perfect for Compact Places

The Keurig K Classic is quite a basic coffee maker and looks exactly like that. If you are not fond of stainless steel and do not have such appliances in your kitchen – this will be a nice addition.

Available Colors

It comes in only 2 colors: black and red, so there is not much to choose from. The good part might be the sleek style this device has so it fits almost everywhere over the counter – both in your kitchen or office.

Operational Efficiency

The operation is easy as all functions are placed in one area on the top with the light indicators. It will stand just as tall as a juicer in your kitchen and will blend well the surrounding. At 13.3” in height it is easily usable over the counter with adding water or cleaning also very accessible.

Removable Drip Tray Convenience

With the removable drip tray, you can place travel mugs and other mugs as per your choice. This really helps when making coffee directly in your travel mug, eliminating the need to make coffee first in a different cup then transfer it to travel mug.

Keurig K55 and its Easy Cleaning Process

One of the reasons so many people prefer the Keurig K55 is its cleaning feature. It has a descaling button that self-cleans the device once activated. Any calcium deposits will clean away and the tray is removable and can be cleaned easily.

Cleaning Efficiency

Since the K-Cups contents do not come into contact with the device – it makes it easier to clean. Although other coffee makers need a more cumbersome cleaning process over time with descaling solutions, this one does not and this makes it a better machine than others.

Product Service Requirements

The inside of the device will need a service twice a year – still not that bad. The steel mesh comes out and needs to be cleaned. The calcium deposits are taken care of by the device itself through its descaling feature and you will need to do this 2-3 times so no residue is left inside.

Water Filters

The K Classic has 2 built-in water filters to make your coffee which are inside the package. But after 2 months or 120 tank refills they need to be replaced as they will get dirty with time and usage.

Keurig K55 – Product Performance

The K55 is a decent coffee maker that makes great strong coffee, decaf, mild or flavored. With K-Cups pods, you have unparalleled access to great brands like McCafe, Green Mountain Coffee, Starbucks and Lipton. So you have a variety of coffee and tea options from the comfort of your home.

Its built-in water filter makes sure only clean water is used in brewing that perfect coffee cup. Warming up will take less than 5 minutes and you can use the K-Cups or a larger mug or travel mug when you need coffee on-the-go.

Brew Speed – a Quick Coffee Brewer

For the next brew, it only needs 15 seconds which is pretty fast! The 3 cup sizes are 6 oz, 8 oz and 10 oz giving you a choice of beverage quantity. K-mugs and K-carafe will not work with this model.

Overall Performance – Good for Single Cups

The K55 is a fast coffee maker with great tasting coffee from Keurig. The taste can be set according to your liking. For example, a smaller cup size for a stronger coffee is great. More water and less coffee means weaker coffee – lesser water means a stronger brew.

Temperature Control – One of the Negatives of K55

The temperature cannot be changed and can be a cause for concern for some users.

The Good side

Online reviews of the Keurig K55 suggest that this coffee maker is a good option when it comes to the wide variety it gives through K-Cup pods of coffee. It is also good in the design department with sleek styling and easy access to the water refilling and cleaning parts.

Keurig K55 Alternate Products

Since the Keurig K55 has major durability and reliability issues, you can consider one of the relevant products from the Keurig product range.

Keurig K Elite Coffee Maker

Keurig K Elite Coffee Maker is the top of the line product in this series. Although it costs much more than the K55, it also has a bunch features packed with it.

It has a digital interface with temperature control and time. It also has 4, 6, 8, 10 and 12 oz cup sizes – with 12 oz being a good large cup. It is the coffee maker for those that love iced coffee too as it has iced coffee making capability.

The water reservoir is also very big with a capacity of 75 oz and is removable. It comes with a single serve strength setting too. It is almost the same size as the K55.

Keurig K Select Coffee Maker

Keurig K Select Coffee Maker is another option similar to the K55 – but certainly better. It comes with four cup sizes: 6, 8, 10 and 12 oz. It also comes with a single serve strength control feature.

It has a better water capacity than K55 at 52 oz and comes with a removable reservoir. This model is slightly sleeker as well. This option costs a bit more than the K55 but much less than K Elite mentioned above so will appeal to a person wanting more options from the device.

The Keurig Mini Coffee Maker

The Keurig Mini Coffee Maker is the compact maker and has no descaling function. It also needs water to be filled every single time.

It is very sleek and small so it fits best in tighter kitchen or office spaces. It is also cheaper than the K55 as there are lesser features in this model. This will appeal to young coffee lovers or people that want a sleek option for their living space.

Our Final Word on Keurig K55 Coffee Maker

The Keurig K55 Coffee Maker is great at coffee making with several features that are good for your coffee, but the machine is not so durable. So as long as your device is working fine, you will love it – but if there is a problem with it due to clogging or otherwise – it might not work at all.

Its descaling feature is good at cleaning the calcium residue but since there is no manual cleaning, sometimes the residue may be so clogged that the auto feature may not work properly causing the machine to jam. In this case, the machine is useless and you will need to buy a new coffee maker!

For people looking for reliability rather than coffee options, the Keurig Mini Coffee Maker is the ultimate choice as it does not feature an auto descaling option and needs to be cleaned manually.
