Ninja TB401 vs SS401
Ninja TB401
BlendSense sensor tech, 1800 peak watts, and a dedicated 8-cup food processor bowl.
Ninja SS401
7 Auto-iQ functions, an XL smoothie bowl maker, and slicing/shredding/grating discs in one pitcher.
The main difference between the Ninja TB401 and SS401 is how each system handles food processing. The TB401 pairs its pitcher with a separate 8-cup food processor bowl for chopping, purees, and dough. The SS401 skips the second bowl entirely — it processes everything inside one 72-oz pitcher using a feed-chute lid and interchangeable slicing, shredding, and grating discs.
Power differs too: the TB401 runs on an 1800-peak-watt motor with BlendSense sensing, while the SS401 runs on a 1600-peak-watt motor with smartTORQUE and 7 preset Auto-iQ programs. The SS401 also adds two things the TB401 doesn't include out of the box — an XL smoothie bowl maker with a built-in tamper, and a 24-oz nutrient extraction cup.

Under The Hood
Smart Technology: BlendSense vs 7-Function Auto-iQ
The TB401's BlendSense reads the pitcher's contents in real time — Torque Detect adjusts for fresh versus frozen ingredients, Portion Detect factors in load size, and Liquid Detect flags when a blend needs more liquid. It's largely hands-off once you press the dial.
The SS401 takes a program-based approach instead: 7 preset Auto-iQ functions cover smoothies, extractions, bowls, spreads, chopping, food processing, and dough, backed by smartTORQUE to keep the motor from stalling on dense loads. Rather than sensing what's inside, it runs a tuned sequence for whichever function you select.
The practical difference is where the "smart" work happens — automatically in the TB401, or through a wider menu of purpose-built programs in the SS401.
Room To Cook
Capacity & Batch Size
Both systems center on a 72-oz pitcher, so smoothie and frozen drink batches land in similar territory. Where they diverge is processing capacity: the TB401's 8-cup bowl is a separate, dedicated container, while the SS401 processes inside the same 72-oz pitcher used for blending, which means fewer parts to buy but one container doing double duty.
The SS401's 18-oz XL smoothie bowl maker and 24-oz nutrient extraction cup add batch options the TB401 doesn't offer out of the box, particularly for single-serving smoothie bowls.
Look & Feel
Design & Build Quality
The TB401 keeps its control panel to a single dial with a clean black finish. The SS401 leans into its multi-function identity with more visible controls for its 7 programs, finished in silver, and its feed-chute lid with a two-part pusher is built specifically around disc-based processing.
Both use dishwasher-safe components and a comparable footprint, so the choice comes down more to how you want to process food than to overall build quality.
In The Kitchen
Real-World Performance
With 200 more peak watts, the TB401 has a slight edge on raw crushing power, and BlendSense's auto-adjustment reduces the need to guess at settings. The SS401 counters with smartTORQUE to resist stalling and a broader spread of 7 dedicated programs, plus hardware — the smoothie bowl maker and extraction cup — purpose-built for tasks the TB401 doesn't specifically target.
For slicing, shredding, and grating, the SS401 is the clear choice since the TB401 doesn't include disc attachments at all. For heavy chopping and dough in a separate bowl, the TB401's dedicated processor bowl tends to feel more purpose-built.
Match It To Your Routine
Best Use Cases
Daily Smoothies
Both handle everyday smoothies well; the TB401 needs less trial and error to nail consistency.
Smoothie Bowls
The SS401's XL smoothie bowl maker with tamper is purpose-built for this; the TB401 isn't.
Cookie Dough
The TB401's separate processor bowl handles dough with less setup than switching discs.
Slicing & Shredding
Only the SS401 includes reversible slicing/shredding and grating discs.
Nutrient Extraction
The SS401's dedicated extraction cup targets smooth, nutrient-dense single servings.
Chopping & Salsa
The TB401's 8-cup bowl offers more dedicated chopping room per batch.
