The Ninja Specialty Coffee Maker CM401 earns a strong 4.6 rating for its dual hot and cold brew capabilities, generous brew size options (from a single cup to a full carafe), and a built-in frother that delivers velvety milk foam. It is a top choice for households that want both iced coffee and hot specialty drinks without buying two machines. However, the cold brew function is not true slow-steeped cold brew (it uses a rapid brew method), and the carafe is not insulated. Compared to the Ninja Coffee Bar, the CM401 adds cold brew and a dedicated frother, while the DualBrew Pro offers a more traditional drip experience with a separate hot water dispenser. Overall, if you value versatility and convenience over traditional cold brew methods, the CM401 is a solid investment.

The Ninja Specialty Coffee Maker CM401 is a versatile machine that promises to handle both hot and cold coffee with a built-in frother. Our editorial team compared specifications, buyer feedback and key decision factors to give you an honest assessment of its performance, ease of use, and value compared to other Ninja models.
Design and Build
The CM401 features a sleek, modern design with a brushed stainless steel finish and a compact footprint. It measures about 11.6 x 9.1 x 15.4 inches, making it suitable for most countertops. The control panel is straightforward with buttons for brew style, brew size, and the frother. The 50-ounce water reservoir is integrated into the back and is not removable, which some users find less convenient for cleaning. The carafe is glass with a plastic handle and lid; it is not insulated, so coffee cools faster than in a thermal carafe. The fold-away frother is a nice space-saver, but its plastic construction feels less premium. Overall, the build quality is solid for the price point, though not as robust as higher-end machines.
Performance: Hot Brew
The CM401 offers brew styles Classic, Rich, and Over Ice. Classic produces a balanced cup, while Rich extracts more flavor for a bolder taste. Over Ice brews a double-strength concentrate directly over a cup of ice to prevent dilution. The brew temperature is consistently hot, and the showerhead design ensures even saturation of the coffee grounds. Users report that the hot coffee is flavorful and satisfying, though not as hot as some traditional drip machines. The six brew sizes give excellent flexibility: from a single cup (8 oz) to a full carafe (50 oz). The programmable delay brew is convenient for waking up to fresh coffee.
Performance: Cold Brew
The cold brew function is one of the main selling points. It uses a rapid cold brew cycle that runs water through grounds at room temperature for about 10-15 minutes, producing a smooth, less acidic iced coffee. However, it is not a true slow-steep cold brew concentrate. Some coffee enthusiasts find the result lacking in depth compared to traditional 12-hour cold brew. For everyday iced coffee, it works well and is much faster. The Over Ice option is also popular for quick iced coffee. Keep in mind that the cold brew setting uses more grounds per cup, so you may go through coffee faster.
Built-in Frother
The fold-away frother has two settings: hot and cold. It can froth milk (dairy or plant-based) to a thick foam for lattes, cappuccinos, or macchiatos. The frother is easy to use: fill the included whisk to the fill line, select the setting, and press start. It produces a good amount of foam, but the texture is airy rather than velvety. It is not as powerful as a steam wand, but for a home machine, it is a nice addition. Cleaning the frother whisk is simple: rinse under water. The frother is not designed for large quantities; it works best for single servings.
Ease of Use
The control panel is intuitive with clear labels and a bright display. The brew size and style buttons are easy to press, and the machine responds quickly. The water reservoir is easy to fill from the top, though not removable. The carafe has a drip-free spout and a handle that is comfortable to hold. The frother folds away neatly when not in use. The instruction manual is clear, and most users report being able to set up and use the machine within minutes. The programmable features are straightforward to set. Overall, the CM401 scores high on ease of use.
Cleaning and Maintenance
Cleaning the CM401 requires regular descaling to prevent mineral buildup. The machine has a descaling mode that cycles a solution through the system. The water reservoir and brew basket are accessible for wiping, but the non-removable reservoir makes thorough cleaning a bit tricky. The carafe and filter basket are dishwasher safe. The frother whisk should be rinsed immediately after use to prevent milk residue from drying. Some users report that the brew basket can be messy when removing used grounds, especially for larger brews. Overall, maintenance is manageable but not as easy as machines with removable water tanks.
Common Buyer Complaints
Based on buyer feedback, the most common complaints include: the carafe is not insulated and coffee cools quickly; the cold brew is not as strong as expected; the water reservoir is difficult to clean; the frother can be noisy; and some units have had issues with the brew basket not sealing properly, causing grounds to leak into the carafe. A few users also mention that the machine is slightly taller than expected, so check clearance under cabinets. Despite these issues, the majority of reviews are positive, praising the versatility and convenience.
Comparison with Other Ninja Models
Compared to the Ninja Coffee Bar (discontinued), the CM401 adds cold brew and a built-in frother. The Ninja DualBrew Pro offers a larger 12-cup carafe and a separate hot water dispenser but lacks cold brew and a frother. The Ninja Hot & Cold Brewed System (CF091) is a similar model but with a glass carafe and no frother; the CM401 is the upgraded version with frother. If you want the most versatile single-serve and carafe option with milk frothing, the CM401 is the best choice in Ninja's lineup. For those who prioritize large batches and hot water on the go, the DualBrew Pro may be better.
In summary, the Ninja Specialty Coffee Maker CM401 is a strong contender for anyone wanting a multi-functional coffee maker that can handle hot, iced, and cold brew with a frother. It is not perfect, but its versatility and ease of use make it a popular choice among home coffee enthusiasts. Check the current price on Amazon to see if it fits your budget.

Questions before you buy
Can the Ninja Specialty Coffee Maker make true cold brew?
No, it uses a rapid cold brew process that brews hot coffee over ice to quickly chill it, or a cold brew setting that runs water through grounds at room temperature for a shorter time. The result is a smooth, less acidic iced coffee but not the concentrated, long-steeped cold brew you get from a dedicated cold brew maker.
How does the CM401 compare to the Ninja Coffee Bar?
The CM401 replaces the older Ninja Coffee Bar. Key differences: the CM401 adds a dedicated cold brew function and a built-in fold-away frother, while the Coffee Bar had a separate frother attachment. The CM401 also has a slightly larger water reservoir and updated brew size options. The Coffee Bar is discontinued but still available from some retailers.
Does the frother work well for latte art?
The frother produces a decent microfoam, but it is not as fine or consistent as a steam wand on an espresso machine. It works well for cappuccinos and lattes but may not create the velvety texture needed for intricate latte art. It is a good entry-level frother for home use.
What is the difference between the Ninja Specialty and the Ninja DualBrew Pro?
The DualBrew Pro is a full-size 12-cup drip machine with a separate hot water dispenser for tea or instant soup. It does not have a cold brew function or a built-in frother. The Specialty CM401 is more compact and focuses on versatility with multiple brew sizes and cold brew. Choose the DualBrew Pro if you need large batches and hot water on demand; choose the Specialty if you want iced coffee and milk-based drinks.
Is the water reservoir easy to clean?
The water reservoir is not removable, so you must clean it in place. You can use a descaling solution and a soft brush to reach the bottom. Some users find this inconvenient compared to removable tanks. The reservoir has a fill line and a lid that flips open for easy refilling.
