Best Cold Press Juicers: Slow Juicers Compared
If you've already decided on a cold press juicer, the more useful question is how the machines differ in feeding, batch workflow, cleanup, dimensions and everyday use. This guide compares six slow juicers from Nama, Hurom and Kuvings on exactly those points. (“Cold press” and “slow juicer” describe the same category: a slowly turning auger that presses juice from produce.)

Feeding Systems: Self-Feeding vs Auto-Feeding vs Dual Feed Chute
Self-Feeding Hopper
Nama J2 · Nama J3 · Nama J2 XL · Hurom H400
You load prepared ingredients into a hopper and the machine gradually draws them in, so you aren't pushing each piece down a chute.
Large Auto-Feeding Hopper
Kuvings AUTO10 Plus
The design emphasizes loading a larger batch at once and reducing repeated feeding during a session.
Dual Feed Chute
Kuvings REVO830
Two openings accommodate different ingredient shapes, including a dedicated opening for long produce. You feed by hand.
The best feeding system depends on what and how much you juice.
Batch Workflow
How you load ingredients shapes a juicing session more than any single specification. With a self-feeding hopper, you prepare produce, fill the hopper and let the machine work through it; hopper size (such as the J3's 34 oz / 1 L versus the J2 XL's Large Hopper) decides how much fits per load. The AUTO10 Plus is built around loading a larger batch at once. The REVO830 keeps you at the machine, feeding by hand, but its long-produce opening can reduce chopping.
Motor Speed: Does a Lower RPM Make a Better Juicer?
RPM (revolutions per minute) tells you how quickly a rotating component, usually the auger, turns. Among the machines in this guide:
- Nama J2
- 50 RPM
- Nama J3
- 50 RPM
- Nama J2 XL
- 50 RPM
- Kuvings AUTO10 Plus
- 50 RPM
- Kuvings REVO830
- 50 RPM
- Hurom H400
- 90 RPM
A lower RPM does not automatically mean higher juice yield, more nutrients or better juice.
Auger geometry, chamber design, the strainer (or lack of one) and the ingredients themselves all shape the result. That's why this guide doesn't rank machines by RPM.

Want a Juicer and Blender?
The Nama C2 combines a 200W / 50 RPM cold press juicer and a 1,000W high-speed blender on one base. Because it's a multifunction machine, it isn't one of the six dedicated picks here, but it's worth a look if you make smoothies as well as juice.
Which Cold Press Juicer Fits Your Routine?
Ingredients: How Cold Press Designs Differ
Celery
Long, fibrous stalks make feed design matter. The REVO830 is particularly relevant because of its dedicated long-produce opening; self-feeding machines like the J2, J3 and H400 also juice celery, usually with stalks cut to fit the hopper. More in our celery juicer guide.
Ginger
Small, dense, fibrous roots can need different preparation depending on the machine, such as slicing into pieces or juicing alongside other produce. More in our ginger juicer guide.
Carrots
Long carrots suit the REVO830's dedicated opening, while hopper machines generally need them cut into pieces that sit and feed well in the hopper. More in our carrot juicer guide.
Leafy Greens
Technique and recipe combinations matter: rolling greens or alternating them with firmer produce is a common slow-juicer approach on any feed system.
We don't publish comparative yield numbers.
Cleanup Design
We haven't measured cleaning times, so there's no measured winner here. The biggest design difference is the strainer. The Hurom H400 uses a strainer-free Easy Cleaning Multi Auger, removing the conventional fine-mesh strainer. Nama and Kuvings machines use different chamber and strainer systems depending on the model.
For frequent users, cleanup preference can matter as much as juicing performance: a machine you don't mind rinsing is one you'll keep using. Details in our Hurom H400 review.

For the Kuvings AUTO10 Plus and REVO830, check current dimensions on your regional Kuvings store; we haven't verified figures for them. Remember to measure the clearance under your cabinets as well as counter depth.
Motor Wattage and Continuous Operation
- Nama J3
- 130W
- Hurom H400
- 150W
- Nama J2
- 200W
- Nama J2 XL
- 200W
- Kuvings AUTO10 Plus
- 200W
- Kuvings REVO830
- 240W
Wattage describes the motor, not the juice. Higher wattage doesn't automatically mean better results, because auger and chamber design shape how that power is used. Treat it as one specification alongside feed system and cleanup design.
Continuous operation limits tell you how long a machine is designed to run in one session. Of the models here, Kuvings states up to 45 minutes for the AUTO10 Plus; we haven't verified comparable manufacturer figures for the others, so we don't list them.

Cold Press Juicer FAQ
What should I look for in a cold press juicer?
Once you've chosen a slow juicer, the practical differences are the feeding system (self-feeding hopper, large auto-feeding hopper or Dual Feed Chute), hopper size and batch workflow, cleanup design (conventional strainer or Easy Clean systems), footprint and height, and current warranty terms.
What is a self-feeding cold press juicer?
A machine with a hopper that gradually draws prepared ingredients into the auger, so you load a batch rather than pushing each piece down a chute. In this guide, the Nama J2, J3, J2 XL and Hurom H400 are self-feeding; the Kuvings AUTO10 Plus uses a large auto-feeding hopper.
What is the difference between self-feeding and direct-feed machines?
Self-feeding and auto-feeding machines let you load a hopper and step back. Direct-feed chutes, such as the Kuvings REVO830's Dual Feed Chute, have you feed ingredients by hand, though the REVO830's dedicated long-produce opening can reduce chopping for celery, carrots and cucumber.
What RPM should a cold press juicer use?
Most machines in this guide run at 50 RPM; the Hurom H400 runs at 90 RPM. All are slow-juicer speeds. RPM alone doesn't determine which machine suits you.
Does lower RPM mean better juice?
Not automatically. RPM only tells you how quickly a rotating component turns. A lower RPM does not automatically mean higher juice yield, more nutrients or better juice; auger geometry, chamber design, strainers and the ingredients all matter too.
How important is motor wattage?
It's one specification, not a performance score. The machines here range from 130W (Nama J3) to 240W (Kuvings REVO830). Auger and chamber design shape how that power is used.
Are cold press juicers good for celery?
Cold press juicers are commonly chosen for fibrous stalks like celery. Feed design matters: the Kuvings REVO830's long-produce opening can reduce chopping, while hopper machines take cut pieces in bulk. See our celery guide for more.
Are cold press juicers good for ginger?
They can juice ginger with appropriate preparation, such as slicing it into pieces and juicing it alongside other produce. See our ginger guide for more.
Are cold press juicers good for carrots?
Yes, with preparation that suits the feed design. Long carrots suit dedicated long-produce openings, while hopper machines generally need them cut to fit. See our carrot guide for more.
How do Easy Clean juicers work?
Hurom's Easy Cleaning Multi Auger, used on the H400, removes the conventional fine-mesh strainer from the juicing system — the part many slow-juicer owners spend the most time brushing. We don't publish measured cleaning times.
How do I choose between cold press models?
Start with workflow. Nama's J2, J3 and J2 XL use self-feeding hoppers in different sizes; the Hurom H400 centers on its strainer-free Easy Clean design; Kuvings offers a large auto-feeding hopper (AUTO10 Plus) and a Dual Feed Chute (REVO830). Then compare counter space, batch size and current warranty terms.
Is there a Nama juicer discount code?
Yes. BestSlowJuicer readers can use code MOH10 for 10% off eligible Nama purchases. Terms may change, so confirm the discount at checkout.
