The promise of a cold press juicer is simple: quiet, slow, and a higher yield than a centrifugal machine. The reality is often a cycle of pushing produce down a chute, hearing the machine strain, pressing reverse, and digging out a mat of tangled fiber. The Ninja NeverClog was built to break that cycle, pairing a high-torque 150-watt auger with a design that routes fiber out of the way before it can jam. I spent a month with the JC151 running leafy greens, root vegetables, citrus, and wheatgrass through it to find out whether the name holds up in the kitchen.

Design and Build
The JC151 is a vertical slow juicer in a charcoal finish, with a compact footprint that fits easily under standard upper cabinets. The feeding chute sits on top with a wide mouth that accepts most produce without pre-cutting into tiny pieces, and the auger grinds slowly and quietly, the signature trait of a masticating machine. The main assembly locks together with a simple twist and comes apart into several pieces that stack neatly for storage or go into the dishwasher.
The two containers are clearly labeled and sized for real sessions: a 24-ounce jug catches the juice, and a 36-ounce pulp container holds the fiber that would otherwise clog a lesser machine. The pulp control dial sits on the side of the unit and lets you choose how much pulp makes it into your glass. The base is weighted enough to stay planted while the auger works, and the silicone feet absorb the mild vibration of the motor.
Key Features
The headline feature is the NeverClog design, which uses a larger, more open auger and a pulp path that clears fiber before it builds up. In practice that means leafy greens like kale and spinach go through with far fewer stalls than a typical slow juicer, and the reverse function clears the rare jam in seconds instead of forcing a full teardown. The 150-watt motor runs the auger at a low speed that preserves the natural color and flavor of the juice while keeping noise to a conversational hum.
Total Pulp Control is the second headline. A small dial on the side adjusts a gate that regulates how much pulp slips through into the jug, so you can dial in a pulpy, fiber-rich green drink or a smooth, clarified juice without swapping parts. Two one-touch programs handle the most common jobs, one for softer fruits and vegetables and one for hard produce, taking the guesswork out of speed selection. If you want to compare the current price against other cold press juicers in this class, the Amazon listing for the Ninja NeverClog JC151 is a useful reference.
Real-World Performance
I started with the test that breaks most juicers: a full batch of kale and celery with a green apple for sweetness. The NeverClog chewed through the leaves with only one brief pause, which I cleared with a quick reverse, and the machine finished the batch without the ritual of clearing a clogged filter that defines other slow juicers. The juice came out a vivid, grassy green with a clean flavor and none of the foam or heat that centrifugal machines introduce.
Carrots and beets were the next test, and here the machine was effortless. The hard produce program pushed through several large carrots in seconds, and the juice separated cleanly with a rich, deep color. I ran the pulp dial to its open position for a fiber-heavy breakfast drink and closed it down for a smoother evening glass, and the difference was clear in both texture and appearance. The 24-ounce jug filled about two tall glasses per batch, and the 36-ounce pulp container absorbed a full session without needing a mid-run empty.
Citrus and wheatgrass rounded out the month. Oranges went through quickly with the soft program, and the wheatgrass, a notoriously difficult ingredient for slow juicers, produced a concentrated dark shot with only one reverse needed. A ginger and carrot blend, a favorite for a morning reset, came out bright and balanced with the ginger fully ground rather than passed through in chunks. Cleaning was the pleasant surprise: the auger, filter, jug, and pulp container all went into the top rack of the dishwasher, and the handful of parts that needed hand wiping took under two minutes. The whole machine disassembles without tools, which is the difference between daily use and a juicer that gathers dust.
Pros and Cons
Pros:
- Handles fibrous greens with far fewer clogs than typical slow juicers
- Total Pulp Control dial changes texture without swapping parts
- Quiet 150-watt motor with two one-touch programs
- Most parts are dishwasher safe for easy cleanup
- Compact vertical footprint fits under cabinets
- High yield with minimal foam or heat
Cons:
- Very dense produce still needs occasional reverse use
- Single-batch 24-ounce jug limits big sessions
- Pulp control only spans a small range of textures
- Some parts are small and easy to misplace
How It Compares
Cold press juicers split into vertical auger machines like the Ninja, horizontal auger juicers, and faster centrifugal models, and the right pick depends on what you juice. I compared the JC151 against a horizontal slow juicer and a centrifugal juicer to see where each earns its place.
| Feature | Ninja NeverClog JC151 | Horizontal Slow Juicer | Centrifugal Juicer |
|---|---|---|---|
| Motor | 150W vertical auger | Variable, slower | High speed |
| Leafy greens | Strong, few clogs | Good, more manual | Foamy, lower yield |
| Pulp control | Dial on the side | Limited or none | None |
| Noise | Quiet hum | Very quiet | Loud |
| Cleaning | Mostly dishwasher safe | Hand washing common | Quick, parts rinse |
| Yield | High | Very high | Moderate |
Against a horizontal slow juicer, the Ninja wins on convenience, since its vertical design takes less counter space and its dishwasher-safe parts make cleanup faster, though a horizontal machine can edge it out slightly on yield for extremely fibrous crops. Against a centrifugal juicer, the Ninja wins on juice quality and noise, trading the speed and simple cleanup of a centrifugal machine for better flavor and less foam. For a home juicer who wants greens without a clogging battle, the JC151 is the best all-rounder of the three, and it is the one I left on the counter.
Who Should Buy It
Buy the Ninja NeverClog if you want a daily green juice without the jam-and-reverse ritual, if you prefer a machine that cleans itself in the dishwasher, or if you like fine control over how much pulp reaches your glass. It is a natural fit for someone juicing leafy greens, roots, and citrus a few times a week.
Skip it if you juice in large batches for a whole household, if you need a machine that handles whole produce without any prep, or if you are happy with the speed of a centrifugal juicer and do not mind the foam. For everyone else, this is one of the most practical cold press juicers available. You can check the current price for the Ninja NeverClog JC151 on Amazon when you are ready to start juicing.
How We Test
I ran the juicer for a month across four ingredient groups: leafy greens, hard root vegetables, soft citrus, and wheatgrass. I measured clog frequency, yield, juice clarity, noise, and cleaning time, and I used the pulp control dial at both extremes to confirm the texture range.
I deliberately started with kale and celery, the ingredients that defeat most slow juicers, and repeated the batch three times to confirm the NeverClog behavior was consistent. I did not test the machine for commercial volumes or frozen produce, so those use cases remain unverified here. Independent coverage such as CNET's guide to the best juicers is a useful reference for how the category compares. The Ninja NeverClog JC151 listing on Amazon shows the current price and shipping details.
Questions People Ask
Does the NeverClog really prevent clogging with leafy greens?
In testing, the open auger design and quick reverse cleared fibrous produce like kale and celery far faster than most slow juicers, though very dense mats still benefit from a slow push.
How does Total Pulp Control change the juice?
The dial adjusts how much pulp passes into the glass, giving you a cloudy, fiber-rich juice at one end and a clearer, smoother juice at the other, all without changing parts.
Is the Ninja NeverClog dishwasher safe?
Most of the removable parts, including the auger, filter, jug, and pulp container, are dishwasher safe on the top rack, which makes cleanup far easier than a manual juicer.
How much juice can I make at one time?
The 24-ounce jug holds a single batch, and the 36-ounce pulp container handles a full session of fruit and vegetables before you need to empty it.
