The catch
Ninja Foodi Power Blender Ultimate System
The main pitcher serves both large blends and disc processing.
Side by side
Ninja SS401 fits when sliced or shredded vegetables and thick smoothie bowls both belong in the same appliance brief. BN801 fits when you want a separate processor bowl and two 24-ounce travel cups. A 72-ounce pitcher with a 64-ounce liquid limit comes with both, but the food-prep accessories lead to different workflows.
Before you buy
For sliced cabbage or shredded vegetables, the feed-chute and disc system for that job is included with SS401. BN801's separate processor bowl handles chopping and dough, but its standard package lacks those discs. The tradeoff is that SS401 processes through the same main pitcher used for large blended drinks. Plan the order of those tasks and any washing between them, and do not expect the disc package to create a second processor bowl.
Where this comes from
The cutting methods and shared vessel are established by exact package contents. No slicing-uniformity test is made, and no claim that chopped food is nutritionally or culinarily equivalent to sliced food.
The catch

The catch

Feed-chute slicing and smoothie-bowl tools are set against a separate processor bowl and two travel cups in the exact Ninja system packages.
This one comes down to food-processing vessel and supplied disc tools first, then to the limits of your own setup.
Which one fits
BN801 does not include them, but SS401 does.
Two matching 24-ounce cups are included with BN801.
The bowl maker with its built-in tamper comes with SS401.
An 8-cup processor vessel is included with BN801.
In practice
For sliced cabbage or shredded vegetables, the feed-chute and disc system for that job is included with SS401. BN801's separate processor bowl handles chopping and dough, but its standard package lacks those discs.

Two people making different smoothies get two 24-ounce cups from BN801. SS401 includes one travel cup and an 18-ounce bowl maker, a different vessel with a different purpose. Blends still run in sequence, since both use one motor base. BN801's advantage is having two supplied travel cups available after blending, while SS401's package better serves someone making a spoonable bowl.
The listed one-versus-two travel cups and the separate bowl-maker attachment are what the conclusion rests on. Cup labels are not a promise of finished-drink fill to the brim.
A 64-ounce maximum liquid capacity is specified for both selected 72-ounce pitchers. A choice between these systems for a liquid batch should therefore focus on the recipe and accessory workflow.
No additional 8 ounces of safe liquid capacity is inferred from the larger molded-vessel label, because the two stated limits are equal.

Ninja, SS401
Made for thick blends, it has a powered bowl maker, an extraction cup and processor hardware next to the large pitcher.

Ninja, BN801
A time-tested 1,400-peak-watt bundle: large blender, processor bowl, dough blade and two travel cups.
Spec by spec
| Spec | Ninja Foodi Power Blender Ultimate System | Ninja Professional Plus Kitchen System | In practice |
|---|---|---|---|
| Main pitcher | 72 ounces, maximum liquid 64 ounces | 72 ounces, maximum liquid 64 ounces | 72 ounces of liquid working capacity is not what the headline pitcher size means. |
| Food-processing vessel | Main pitcher with processing lid | Separate 8-cup processor bowl | BN801 separates the vessels, while SS401 shares its pitcher across jobs. |
| Supplied disc tools | Slicing/shredding disc and grating disc | No slicing or shredding disc in this package | A disc produces controlled slices that BN801's chopping blade does not. |
| Personal travel cups | One 24-ounce cup | Two 24-ounce cups | Two separate travel drinks can be held in BN801's supplied matching cups. |
| Thick-mixture vessel | 18-ounce bowl maker with built-in tamper | No bowl-maker vessel supplied | An ordinary travel cup is not the same as the SS401 bowl maker. |
| Auto-iQ programs | 7 | 5 | Differing vessel and attachment packages account for the program counts. |
Trade-offs
Change of plan
Go with Ninja Foodi Power Blender Ultimate System. The feed-chute disc tools are included with SS401.
Go with Ninja Professional Plus Kitchen System. The BN801 package is laid out that way.
Decision guide
SS401 is the fit when sliced or shredded vegetables and thick smoothie bowls share the same appliance brief, and BN801 is the fit for a separate processor bowl and two 24-ounce travel cups. Each includes a 72-ounce pitcher with a 64-ounce liquid limit, while their food-prep accessories create different workflows.
Chopping, slicing and shredding each call for something different. If a recipe needs slices or shreds, the disc package on the SS401 is a decisive advantage. Don’t describe a chopping blade as the same capability.
The second cup on the BN801 suits a further portable drink, while the SS401's bowl maker is for a thick mixture worked with its built-in tamper. Counting both packages as just three containers would hide that difference.
On the SS401, the pitcher handles large blends and disc-based processing alike. The BN801 gives food processing a bowl of its own. Neither has two motors, though separate vessels can keep ingredients apart between sequential tasks.
