Since 1998, Keurig has been a key innovator among beverage brewing systems.

While they have created commercial machines for hospitality and commercial industries, they have established a sizeable amount of quality brewing systems for household use. Currently, they offer over 50 different models of coffee machines.

Keurig[1] offers a variety of beverage coffee makers, many of which are programmable for cup size and brew strength. There are also over 500 different varieties of coffees and beverages that are available in K-Cup pods. The selection of drink options is continuously growing.

These two models share a lot of similarities, but there are a few differences in appearance and features.

Customer reviews for these products reflect the quality, dependability, and performance of the machines.

The K55 seems to be Keurig’s answer to some of the problems that K50 experienced. The K55 has fewer complaints of unexpectedly not working. It also offers a convenient descaling feature that prolongs the life of the machine.

The K50 was unable to handle all types of K-Cup style pods. This issue was corrected with the creation of the K55.

Overall, there are thousands of positive reviews and only a few complaints about either machine.

Difference Between Keurig K50 and K55

#1 – Brew Quality

First, when comparing the Keurig K50 vs K55 you will notice they have very similar brewing systems.

Both coffee makers feature large 48-ounce water reservoirs that can be filled with tap, spring, filtered or purified water. This means that you can brew six, 8-ounce cups before having to refill the water reservoir. An indicator light will let you know when it’s time to refill your machine.

With the simple touch of a button, you can prepare a perfect cup of coffee.

Both coffee machines have three pre-set brewing sizes – 6, 8, and 10 ounces.

By removing the drip tray from the machine, you have the capability to fill a travel mug that is up to 7.1 inches tall.

It takes between 1 – 1 ½ minutes to heat water to approximately 192 degrees Fahrenheit. It only takes 15 seconds before your Keurig is ready to make another cup of coffee.

The K55 boasts a smooth and palatable cup of coffee. This is in part because of the charcoal filtration system. This feature filters water by removing impurities, such as chlorine, salt, minerals, and sediment. These particles are often found in typical household tap water.

Because the Keurig K50 does not include this filtration system, purified water can help you achieve similar tasting coffee.

The water reservoir is constructed of BPA plastic. Because the water stored in the reservoir is not filtered, some customers have complained of a plastic taste in their brewed cup of coffee.

We would be amiss not to mention that the quality of coffee that is brewed plays a vital part in the role in the overall taste produced. A good cup of coffee is a combination of pure water and superior coffee grounds.

While you are unable to adjust pressure and temperature with the K50 and K55, you can adjust the strength of your coffee by decreasing the size cup you are brewing. A smaller cup means it is not watered down as much and will boost the flavor of the coffee.

#2 – Ease of Use

Like most Keurig machines, both models enable you to make a fresh cup of coffee in only a few easy steps.

After unboxing your Keurig Coffee Maker, we recommend taking a few minutes to read the owner’s guide in its entirety. Also, Keurig has an amazing support team that is able to answer any questions you may have about your new machine.

After plugging in the machine into a power source, fill the water reservoir.

Press the power button and allow the water 4-5 minutes to heat.

Place a cup of your desired size onto the Drip Tray Plate.

Next, add the K-Cup pod into the K-Cup holder, pull the handle down, and select the brew button.

After 1 to 1/ 12 minutes, your hot beverage will be ready to drink.

Then, remove the K-Cup pod and dispose of it in the trash. This process is simple and user-friendly.

Leave the K-Cup holder open to air out. This reduces mildew formation inside of the machine.

Both coffee makers feature an efficient automatic shut-off setting that helps save energy and money. The K50 shuts off after not being used for 30 minutes.

If the K55 hasn’t been used for two hours, the machine will automatically turn off.

#3 – Cleaning & Maintenance

Both Keurig coffee makers are similar in the way they are cleaned and maintained. In fact, the Keurig user’s guide is the same for both models.

Often, your machine will let you know when it’s time to clean it. You might notice a disruption in the stream that is produced from the water flowing out of the K-Cup Pod. This might indicate a clog or mineral deposit that is developing.

Another sign that it’s time to clean your machine is  that your coffee has become more bitter tasting. This can be caused by oil and minerals that have built up inside of the machine and are producing bacteria. Cleaning your machine will keep this from being a regular occurrence.

For every Keurig model, it’s important to regularly clean and disinfect the drip tray and water reservoir. Simply remove them and wash thoroughly with soap and water.

In the user’s guide, you will also find detailed instructions on how to clean the K-Cup holder. This includes how to remove the entrance and exit needles, and the funnel. Keeping these parts clean will help your machine last longer and produce better quality coffee.

Every 3-6 months, depending on the amount of use, the machine should be descaled. This is the process used to clean the inside workings of the coffee maker. Because calcium deposits can develop after normal use, descaling is needed to keep away clogs and obstructions in the brewing process.

If you do not regularly descale your machine, it may become inoperable. You may also notice a decrease in the amount of coffee that is produced per brew cycle.

The Keurig K55 has an auto-descaling function that is as easy as the push of a button. Once the descale indicator light is on, you will know that it’s time to descale your machine.

The Keurig K50 does not offer this function. However, it’s a simple process. Just add the descaling solution and run the machine until the solution has been completely flushed out.

White vinegar is also a non-abrasive option to clean the inside of the machine. Some people have even found that a few drops of lemon juice produce enough acid to break down mineral deposits. This is a more pleasant-smelling option than using a vinegar rinse.

It is vital to the taste of the coffee to keep flushing the machine out until the water is clean and free of odors.

To clean the outside of the machine, simply wipe it down with a wet cloth and disinfectant cleaner. This will remove dust and germs that collect on the outside of the machine.

While cleaning your coffee maker may seem like a hassle, it is worth the investment of time and effort to help extend the life of your machine.

#4 – Build Quality

The Keurig K50 and K55 are ideal for home use. Neither would be considered high-end, complicated coffee making machines. Instead, they are affordable, functional, and easy to operate.

They have a sleek design that is an excellent addition to any stylish kitchen design.

Both machines are made from plastic, with the Keurig K50 slightly smaller than the K55.

Keurig Home Brewers come with a limited one-year warranty. This guarantee covers defects in workmanship that occur under normal use.

Keurig makes functional and intuitive coffee makers that are a pleasure for consumers to use.

Here’s how a Keurig coffee maker works:

A Keurig brewing machine brews K-Cup pod contents by piercing both the foil seal on top and the bottom of the pod at the same time.

A spray nozzle is inserted in the top that forces hot water through the contents of the K-Cup and saturates the coffee grounds.

Next, hot water forces the grounds through the filter by using an intense amount of pressure.

This process produces a freshly brewed cup of coffee every time.

Keurig has also produced a reusable coffee filter that allows consumers to grind their own coffee beans or add a powdered drink mix, such as hot chocolate, to brew in their Keurig.

Our Pick

While there are few differences between the Keurig K50 vs K55, the Keurig K55 is a newer, sturdier, and slightly heavier machine. With this updated model, Keurig may only have made minimal changes, but they were significant improvements.

The K55 is listed as one of the top “single-serve coffee makers” on Amazon. This achievement is based on high customer ratings. There are very few complaints, and overall, customers are very pleased with their purchase.

Neither machine offers added features like LED displays or the ability to control temperature and pressure. But they are practical, affordable single-serve coffee brewers that deliver a quality cup of coffee every time.

The Keurig K55 is considered a “classic.” It is a reliable and dependable machine that has the capability to produce excellent quality cups of coffee for years to come.

With over 500 K-Cup Pod varieties from over 75 brands, your beverage choices are almost endless.

If you want a coffee maker from a notable manufacturer that requires only a small amount of effort and produces excellent results, we recommend that you check out the Keurig K55.
