Description
The Ninja CO401B is a combined blender and food processor, which is a genuinely different proposition from a blender that claims to chop. Ninja lists a 72 ounce blending and food processing pitcher, an XL smoothie bowl maker, a nutrient extraction cup, seven functions, a reversible slicing and shredding disc and a grating disc. The unit measures 8.3 inches wide, 8.7 inches deep and 16.14 inches high and weighs 15.4 pounds.
The listing is unusually thin for a product of this complexity, with a single feature bullet and a description that repeats the product name. That is a documentation problem rather than a product one, and it limits how much can be said with confidence.
Discs Are the Real Difference
Almost every modern blender claims to chop. Very few can slice, shred or grate, because those operations need a spinning disc with a raised blade at the top of a bowl, not an impeller at the bottom of a jug. Food falls onto the disc through a feed chute and comes out the other side in even pieces.
Ninja supplies a reversible slicing and shredding disc and a separate grating disc, and states they work in the same 72 ounce pitcher without a separate processor bowl. That means shredded carrots, coleslaw and shredded cheese are on the menu, which is a food processor job that a blender genuinely cannot do.
For a small kitchen this is the appeal: one motor base, one pitcher, and the functions of a blender and a food processor. The tradeoff is that a combined pitcher is a compromise for both jobs. Blending wants a tall narrow vessel for vortex, processing wants a wide shallow one for disc clearance.
Capacity and the Bowl Maker
Seventy two ounces is a full family size pitcher, matching Ninja’s dedicated blenders such as the BL610. The XL smoothie bowl maker is a separate vessel designed for thick outputs, which is the same problem the Ninja SS151 TWISTi solves with a built-in tamper. A nutrient extraction cup covers single serve drinks.
That is four containers plus two discs plus a blade assembly, and it is worth being realistic about storage. A system of this kind takes a shelf, not a corner of the counter.
Ninja’s nutrient extraction language, marked with a footnote in the listing, means whole produce is blended including skins and seeds rather than juiced and strained. It is a description of the process rather than a health claim.
Controls and Power
The specification gives two speeds and seven functions, with auto shut off. Two speeds is a short list for a machine with this much attached hardware, and the seven functions presumably cover the preset side. The listing does not name them.
The wattage is not published in the main specification. A secondary attribute field carries a 1600 watt figure, which given Ninja’s practice elsewhere is likely to be a peak rating rather than a continuous one, but the listing does not say and it should not be assumed. Voltage is not published either, though a countertop appliance of this type would ordinarily run on a standard 120 volt outlet. Both figures should be confirmed from Ninja’s specification sheet before purchase.

Things To Consider
The listing is the thinnest of any blender in this catalog. There is one feature bullet, the description repeats the title, and there is no published wattage, voltage, cord length, noise rating or warranty term. For a complex multi function appliance that is a lot of missing information, and a buyer cannot compare it feature for feature against a properly documented competitor.
The rating average is 4.4 out of 5 from 32 ratings. Thirty two ratings is a very small sample and should be read as an absence of evidence rather than as a verdict. The model was first listed in March 2023.
Slicing and grating discs are the sharpest components in any kitchen appliance and they are handled by hand for fitting, removal and cleaning. On a machine that will be used by several people, that is a real safety consideration rather than a footnote, and the discs should be stored where they cannot be reached for blindly in a drawer.
Two speeds is limited for manual control, and there is no variable speed dial of the kind a Vitamix A3300 offers. On a machine expected to slice and shred as well as blend, that is a narrow set of options, since disc work and blending do not want the same speed.
A combined pitcher also has to be assembled correctly for each job. Fitting a disc where a blade assembly belongs, or running a disc program with the blade in place, is the sort of mistake a two vessel system prevents by design. The listing does not describe any interlock or keying arrangement, so that should be checked in the manual.
At 15.4 pounds this is heavy for a countertop appliance, and at 16.14 inches high it will fit under a standard wall cabinet only with very little clearance to work with.
Combination appliances are also a single point of failure. When the motor base goes, the blender, the processor, the bowl maker and the extractor all go with it. Separate machines take more storage and fail independently, which on a system carrying this many attachments is a real consideration rather than a theoretical one.
Who It Suits and Who Should Look Elsewhere
This suits a small kitchen that wants a blender and a food processor without buying and storing two machines, and specifically one that shreds and slices regularly: coleslaw, grated cheese, sliced vegetables for a bake. The discs are the genuine capability here and no ordinary blender has them.
It is a difficult recommendation on published data alone given how little the listing states, and buyers should obtain Ninja’s full specification before committing. Households that only blend will get more information, more speed control and a better documented warranty from a dedicated machine in the countertop blender range, and anyone blending single portions should look at the personal size blender options instead.
