Omega 8004 Juicer – Everything You Need to Know
9.4out of 10

The good: The Omega 8004 produces high quality juice and extremely dry pulp. Owners rave about its durability (it uses a GE Ultem auger that is 8 times stronger than other plastics) and versatility (it comes with 6 different nozzles that can turn nuts into nut butter, grind coffee, extrude pasta, make sorbet, etc.). The 8004 is also very quiet (its auger only turns at 80 RPM) and incredibly easy to clean (it only takes 2-3 minutes). Finally, it comes with an industry-leading 15 year warranty.

The bad: The Omega 8004 has a small 1.5″ circular feed chute that requires you to cut some of your produce into smaller pieces before you can begin juicing. Additionally, the 8004 doesn’t do well with soft produce (e.g., oranges, pineapples, tomatoes, etc.); centrifugal juicers are better than masticating juicers for this type of produce.

The bottom line: The Omega 8004 is one of the best masticating juicers on the market. The 8004’s performance, durability, and versatility are best in class. Plus, it’s quiet, easy to clean, and covered by a 15 year warranty.

The Omega 8004 is a dual-stage single auger masticating juicer. During the first stage, it extracts juice by slowly grinding produce with a rotating auger. Then, during the second stage, it filters the juice through a special juicing screen. The result of this process is high quality juice and extremely dry pulp.

The 8004’s auger only rotates at 80 RPM, which makes it very quiet (especially compared to centrifugal juicers that operate between 1,000 and 15,000 RPM). The auger’s slow rotation speed also minimizes heat, prevents oxidation, and reduces foam. Consequently, the 8004’s juice retains more healthy enzymes and nutrients, and it can be stored for longer periods of time without degradation.

The auger’s slow rotation speed makes the 8004 very quiet, while minimizing heat, preventing oxidation, and reducing foam.

Not only does the Omega 8004 produce high quality juice, it also has a very high juice yield, which means you’ll be able to spend less money on produce and still extract the same amount of juice as less efficient juicers. The 8004’s juice yield isn’t as high as triturating (twin gear) juicers; however, after a round of juicing, you can easily feed the pulp back through the 8004 to capture even more juice and increase the yield.

This juicer has such a high juice yield because of its high quality components. Specifically, the 8004 uses a GE Ultem auger, which is 8 times stronger than the plastics used by other juicers. The juicer also uses a powerful commercial-grade motor. These components make the Omega 8004 extremely durable, but if you experience a problem, the juicer is covered by an industry-leading 15 year warranty.

One of the 8004’s few drawbacks is its small 1.5″ circular feed chute. As a result, you will need to cut your fruits and vegetables into smaller pieces so that they will fit in the chute. This isn’t a huge problem for most owners, but if you don’t have time to cut your produce, we recommend selecting a juicer with a larger feed chute.

The Omege 8004 is capable of juicing a wide variety of fruits and vegetables, but it is especially adept at juicing leafy greens (e.g., cabbage, wheatgrass, kale, etc.). The juicer also comes with 6 unique nozzles, which allow it to grind coffee, turn nuts into nut butter, mince garlic, extrude pasta, whip soy milk, and much, much more.

Despite the 8004’s versatility, the juicer does struggle with soft produce (e.g., tomatoes, melons, oranges, etc.). You can overcome this issue by alternating hard and soft produce when you’re using the juicer. However, if you’re only planning to juice soft produce, we recommend selecting a centrifugal juicer.

In addition to the Omega 8004’s durability and versatility, it is also extremely easy to assemble, disassemble, and clean. In fact, most owners report that it takes less than 3 minutes to clean the entire juicer. As a result, the 8004 is one of the easiest to clean juicers on the market.

Ratings & Reviews

The Omega 8004 is universally praised by reviewers and owners as one of the best masticating juicers on the market. The following table summarizes the juicer’s ratings from various online sources (as calculated by real 8004 owners):

Source Rating
4.74.7 / 5.0
Amazon 4.7(4.7 / 5)
Overstock 4.9(4.9 / 5)
Bed Bath & Beyond 4.3(4.3 / 5)
Macy’s 4.8(4.8 / 5)

Based on the Omega 8004’s glowing reviews, owners are absolutely in love with this juicer. The most commonly cited advantages are high quality juice, a high juice yield, durability, versatility, exceptional performance with leafy greens, and incredibly low clean-up times.

The 8004 doesn’t have many negative reviews, but the most commonly mentioned disadvantages are a small feed chute, slower juicing speeds than centrifugal juicers, and trouble with softer produce (e.g., “soft pulpy fruit”). Now, let’s cover each of these positive and negative items in more detail.

Almost every owner agrees that the 8004 produces extremely dry pulp (i.e., it has a very high juice yield). According to a Macy’s reviewer, “When the pulp comes out and you touch it, it’s so dry.” A reviewer on Overstock shared a similar experience by saying, “It delivers much more juice than a cheaper juicer I had previously purchased.”

Omega 8004 Juice

One of the few disadvantages of using masticating juicers is that they’re slower than centrifugal juicers. However, many owners have noted that the speed difference isn’t that noticeable. One Amazon reviewer had this to say about the Omega 8004’s speed: “I was afraid it would be slow. It’s much faster than I was expecting with the auger style process.”

Also, it’s important to note that the 8004’s slow moving auger produces higher quality juice by minimizing heat, preventing oxidation, and reducing foam. An owner described these benefits on Amazon by saying, “There is basically no foam in my juice which is magical. My centrifugal had almost as much foam as juice.” The same owner also raved about how quiet the 8004 is: “You can talk while using it.”

Owners are also quick to point out the juicer’s 15 year warranty, which is the best coverage you’ll find for a juicer. But as comforting as this warranty is, you’ll probably never need to use it because reviewers rave about the 8004’s durability. Just read what this Macy’s reviewer has to say: “I purchased this juicer in May of 1996 and it still works great. I use it every morning… heavy usage, no breakdowns.”

“I purchased this juicer in May of 1996 and it still works great.”

Another extremely popular comment from reviewers is that the Omega 8004 is very easy to clean. All of its parts are dishwasher safe, but even hand washing is quick and easy. An Overstock reviewer described the process as follows: “Clean-up is simple and can be completed in less than 2 minutes. That was a huge selling point for me.” Another owner on Amazon said something very similar: “Cleanup is literally less than 2 minutes, probably the shortest time for any juicer on the market.”

The most common complaint about the 8004 is that it has a small feed chute. As a Macy’s reviewer explains, “This juicer requires that you chop the veggies into pieces that are about an inch in diameter.” However, many owners believe the positives outweight this small negative. For example, here’s how one owner describes the situation on Overstock: “Overall, yes the chute is smaller in comparison to other juicers but I don’t mind spending a few extra minutes cutting the fruits/vegetables to smaller pieces which I get back later when it only takes about 2 minutes to cleanup.”

“Cleanup is literally less than 2 minutes, probably the shortest time for any juicer on the market.”

One of the biggest reasons people choose masticating juicers is their ability to juice leafy greens (e.g., wheatgrass, cabbage, kale, etc.). This was a huge selling point for one Overstock reviewer: “The Omega 8004 is capable of juicing wheatgrass, and that was a requirement for me.” Another owner shared a similar sentiment on Amazon: “You can’t go wrong with an Omega J8004 if you are juicing greens. We would definitely buy this again, but due to the incredibly long warranty, we don’t expect to buy anything for over 15 years!”

Unfortunately, the 8004’s excellent performance with greens doesn’t carry over to certain types of softer produce. One Bed Bath & Beyond owner described the situation by saying, “I mainly juice apples, pineapple, and oranges. This unit is terrible for soft pulpy fruits like that.” He then finished his review with the following comment: “So if you always plan on juicing greens, this juicer is great! But if you plan on juicing soft fruits like me, you’re better off sticking with [a centrifugal juicer].”

Despite the juicer’s issues with softer produce, many owners have reported success by simply alternating hard and soft produce.

An owner described this process on Bed Bath & Beyond: “If you are juicing mushier fruits like citrus, peaches and cucumbers, I’d recommend running those through first, then running through something harder to push the mush through.”

It’s also important to note that a few owners reported slight staining on the juicer’s white plastic after extended use. A reviewer on Overstock explains, “Since I juice a lot of carrots there is some slight staining on the white as with the juice cups they provide, those stain too.”

The staining issue only appears in a handful of reviews, but if this is a concern for you, we recommend buying the Omega 8006 instead. It’s the same juicer as the 8004; however, the 8006 is black and chrome (so it more resistant to staining).

Finally, many owners have commented on the Omega 8004’s versatility.

Omega 8004 Wheatgrass Juice

Omega 8004 Nut Butter

Specifically, they often reference its 6 unique nozzles, which allow it to turn nuts into nut butter, grind coffee, mince herbs, extrude pasta, make baby food, etc. As one Amazon reviewer explains, “We’ve used it to mass-grind coffee with an included grinding option. It grinds a pound of coffee in about three minutes.” Another owner took this a step further, saying, “It has pretty much replaced my blender and food processor.”

The following table summarizes the various pros and cons associated with the Omega 8004:


  • High juice yield
  • Quiet operation
  • Easy to clean (it only takes 2-3 minutes)
  • Durability (8 times stronger GE Ultem auger)
  • 15 year warranty
  • Excels at juicing leafy greens (e.g., wheatgrass, cabbage, kale, etc.)
  • Versatility (6 different nozzles for making nut butter, grinding coffee, extruding pasta, etc.)


  • Small 1.5″ circular feed chute
  • Slower than centrifugal juicers
  • Not great at juicing softer produce (e.g., tomatoes, oranges, pineapples, etc.)

The Omega 8004 is one of the best masticating juicers on the market. It operates slower than a centrifugal juicer, but the slower speed makes it very quiet. Additionally, the juicer’s slower speed reduces heat and minimizes oxidation, which creates higher quality juice. The 8004 also has a very high juice yield, and as a result, it will consistently save you money on produce.

The juicer is extremely durable. It uses a GE Ultem auger, which is 8 times stronger than the plastics used by other juicers, and a powerful commercial-grade motor. Plus, if anything happens, it is covered by an industry-leading 15 year warranty.

The 8004 is able to juice all kinds of fruits and vegetables, but it truly excels with leafy greens (e.g., wheatgrass, kale, parsley, etc.). The juicer struggles a little with soft produce, but its versatility can’t be beat. Using 6 different nozzles, the 8004 is able to extrude pasta, whip soy milk, turn nuts into nut butter, grind coffee, and much more.

The Omega 8004 does have a small 1.5″ circular feed chute that might require you to chop some of your produce into smaller pieces. However, the juicer is so easy to disassemble, clean, and assemble that any additional preparation time is offset by incredibly quick cleanup times.

    i wonder if upgrading to the harder auger will eliminate the problem i have with a lot of pulpiness it clogs my screen quickly with lots and lots of pulp. other than that the juicer is awesome

    • Steve Webb Author on January 26, 2016

      Hi Ron! If you already have the J8004 or J8006, you should already have the harder auger. However, if you have an older model (the J8003 or J8005), the harder auger should definitely make a difference. Good luck… and happy juicing! 🙂
