The Koios juicer B5100 is an affordable juicer machine for anyone. It provides a high juice yield and preserves the maximum nutrients of extracted liquid.

 In that case, a slow masticating system helps reserve vitamins, antioxidants, digestive enzymes, minerals, and other essential nutrients and eventually gives you less oxidized juice. 

Unlike fast centrifugal juicers, a powerful 150-watt quiet powerful motor runs the auger at a speed of 80 rpm (revolutions per minute) efficiently and provides better juice extraction leaving the dry pulp and less food waste. 

This quiet operation also aids in leading a noise-free life and keeps your mood fresh and cool. Besides, you can carry on conversations easily with your family members and friends over the phone. 

When we were juicing different kinds of fruits and vegetables, we observed that some pulps block the juicer. But, a handy reverse function system helped us get rid of clogging at once and assisted us to continue a smooth juicing operation. 

We also observed that this juicer machine provides a satisfactory amount of juice at a time. It can squeeze 30-35 ounces simultaneously. 

If you see its warranty policy, the manufacturer does not offer an equal-year warranty period for all parts. 

According to its warranty policy, the motor base of this juicer is covered under a 10-year warranty policy and the detachable parts are covered by a 3-year warranty. Luckily, it delivers lifetime technical support and customer service. Let’s get into Koios Juicer Review.

The Koios Juicer Review in Detail

Design and construction materials

With 15.7 x 10.2 x 8.8 inches dimensions, koios slow juicer extractor is a compact size design and handy kitchen appliance that saves your kitchen counter space and enables you to move it with ease. This powerful juicer uses BPA-free high-quality baby food-grade plastic materials to build all removable parts. 

The heat-resistant juicing screw is made of BPA-free strong plastic and the strainer is made from stainless steel material. The body color is white and red, and the weight is 9.88 pounds that are lightweight and anyone can carry it easily. The feeding chute is small and you need some prep work before juicing.  


Koios juicer b5100 juice extractor is featured an 80 rpm slow speed robust motor to run the single auger that slightly presses all kinds of fruits and veggies against juicing screen. 

This slow juicing process ensures maximum juice yield. Koios juicing extractor squeezes juice from oranges up to 80%-90%, apples up to 75%-80%, carrots up to 50%-60% celery up to 82%-88%, and gingers up to 82%-866%. 

 We saw that a small feed chute increases the preparation time before conducting juicing. So, for quick and efficient juice squeezing, you have to cut the larger juicing components into small chunks. 

Luckily, koios masticating juicer comes with a BPA-free plastic food pusher by which you can send the hard and soft fruits and vegetables to the juicing chamber quickly and effortlessly. However, it extracts fresh and tasty juice up to 400ml-500ml at a time leaving the dry pulp and less food waste.

Juice quality

Unlike the high-speed centrifugal juicers, koios slow juice extractor operates at 80 rpm of slow speed and creates minimal oxidation meaning less foam, heat buildup, and friction. This lower motion helps keep the nutritional value of fruit and veggies alive and gives you a high-quality, pure, and fresh juices yield. Therefore, you can preserve freshly extracted juice for up to 72 hours (3 days).


We have already known this juicing machine operates at 80 rpm of speed. Lower speed tends to create less friction which reduces the noise naturally. This extractor enables you and your family to lead a healthy and noise-free life creating less than 60 decibels of noise. And also enables you to carry on important conversations over the phone.

What kinds of produce can koios juice?

Koios cold press juicer machine amazingly extracts quality and healthy juice from softer fruits and vegetables, harder fruits and veggies, fibrous fruits and vegetables, celery wheatgrass and leafy greens, and citrus fruits.

It can press some delicious and sweet soft fruits like avocado, pear, melon, papaya, cranberries, banana, kiwifruit, pomegranate, blackberry, mango, peach, strawberry, grapes, raspberries, gooseberries, plums, cherries, and figs.

Moreover, it incredibly pulls out pure and healthy vegetable juice from soft veggies like cucumbers, beets, carrots, beans, zucchini, broccoli, tomatoes, and cauliflower.

 Besides, koios juicing machine can efficiently press leafy green juice from kale, cabbage, basil, brussels sprout, spring onion, beet greens, collard greens, lettuce, spinach, pine tree needles, dandelion greens, peppermint, celery, and wheatgrass.

 It can also crush every drop of juice from citrus fruit like oranges, lemon, lime, mandarin, tangerine, grapefruit, etc. 

You can also crush the ginger, almond nut, butternut, and soy milk, and make baby food with this extractor.

Is it easy to use?

Koios is pretty easy to assemble, disassemble and use. It includes a few easy detachable parts to assemble. You can quickly join the juicing pieces in a few minutes and detach the removable parts after making the juice smoothly. It uses two setting pressure control systems. 

The soft pressure setting facilitates you to make juice from soft fruits and veggies and hard pressure enables you to make juice from hard and fibrous juicing ingredients. But, a small feed chute increases prep time. 

You will need to cut the larger fruits and vegetables into smaller portions for the best juice extraction. However, luckily, it adds a reverse functioning system that enables you to unblock the pulp from the juicer for a smooth and efficient juicing operation.

Is it easy to clean?

 Having a few detached parts, the cleaning process of koios juice extractor is fairly easy and up-front by hand. Moreover, being a dishwasher-safe juice machine, makes the cleanup process a breeze. 

You can use warm water and soap or dishwashing powder to clean all separate parts effectively. To clean unreachable parts by hand, you can use a delivered cleaning brush. Try to wash every inch of the juice strainer after completing juicing. Rub out the motor base with a dry cloth instead of rinsing it in the running water.

Koios juicer compared to other juicers

Koios juicer B5100 vs. Omega NC900HDC juicer

We test both horizontal masticating juicers in our lab and get some obvious similarities and differences.
Both use a 150-watt powerful motor and run a single auger to crush the juicing ingredients at a slower speed of 80 rpm. The feed chutes of both juicers are small and can take up a lot of prep work. You have to cut the ingredients into smaller chunks before putting them into feeding chutes. The quality of juice is almost the same as both use cold press technology to ensure the best quality of juice. Both are equally easy to use and clean and dishwasher-safe.

Koios juicer is much more affordable but less versatile than the omega nc900hdc. You can use an Omega juicer as a multi-purpose machine such as a juicer, a baby food maker, a food processor, an ice-cream maker, and a grinder but you can use koios as a juicer and baby food maker. Koios is more compact than omega and takes up less counter space. Omega leaves drier pulp than koios which means, omega gives more juice yield than koios. Omega also comes with longer warranty years than koios.

Koios slow juicer vs. Breville 800jexl centrifugal juicer

Koios b5100 juicer uses slow masticating technology to crush the ingredients on the other, Breville 800jexl uses a fast speed ultra-sharp titanium cutting disc to cut and extract juice from fruits and veggies. If you are busy enough and want a fast juicing experience, you can have Breville 800jexl juicer. If you want higher juice yield with less oxidized juice, you can buy koios juicer.
Breville 800jexl runs at a fast speed of 6500-13000 rpm and creates high friction, heat build-up, foam, and noise. On the flip side, koios operate at a slower speed of 80 rpm and create less friction, heat build-up, foam, and noise.

The motor power of Breville 800jexl is way higher than koios juice and the feed chutes of the Breville juicer are larger than the koios b5100 juicer which aids to reduce your prepping time.
Koios uses BPA-free plastics build materials, whereas Breville 800jexl uses stainless steel build materials. So, we can say, Breville is more durable than koios.

Koios juicer is cheaper than Breville 800jexl and provides much longer warranty years than the Breville juicer.  Koios comes with a 10-year warranty policy; on the other hand, the Breville 800jexl juicer offers only a 1-year warranty. Having different parts koios is a bit more difficult to assemble and clean up than Breville 800exl but both are dishwasher safe.
