Main trade-off
Ninja Detect Duo Power Blender Pro
No dedicated tamper bowl or dough blade is included.
Head-to-head
Choose Ninja TB301 for two travel cups and BlendSense automatic adjustment. Choose SS351 for its hand-tampered 14-ounce bowl and dough blade when thick spoonable blends or dough are regular tasks. Their main pitchers share the same nominal and maximum liquid capacities, so the smaller attachments should drive this choice.
Before you choose
Both list a 64-ounce maximum liquid fill in a 72-ounce pitcher. A recipe requiring more than that needs batches on either system, regardless of the extra SS351 bowl.
What this is based on
Both specify 72 ounces nominal and 64 ounces maximum liquid. 64 - 64 = 0 ounces of liquid-capacity gain.
Main trade-off
No dedicated tamper bowl or dough blade is included.
Main trade-off
Only one travel cup is supplied alongside the small bowl.

Winner by situation

What matters in practice

Both specify 72 ounces nominal and 64 ounces maximum liquid. 64 - 64 = 0 ounces of liquid-capacity gain.
SS351 lets your hand move ingredients inside its small bowl. TB301 adjusts speed and time electronically. If a thick recipe needs active ingredient movement, an adaptive program does not provide the missing tamper hardware.
SS351 includes a 14-ounce built-in tamper bowl. TB301 lists BlendSense but no dedicated tamper bowl.
TB301's second 24-ounce cup is another travel-drink container. SS351's second small vessel is a 14-ounce bowl with a storage lid. These pieces are useful for different meals and should not be treated as equivalent cups.
TB301 contains two cups with spout lids. SS351 contains one cup plus one tamper bowl. Nominal vessel counts are equal but their purposes differ.

Meaningful differences
| What changes | Ninja Detect Duo Power Blender Pro | Ninja Foodi Power Blender and Processor System | Why it matters |
|---|---|---|---|
| Main pitcher and liquid limit | 72 ounces nominal, 64 ounces liquid maximum | 72 ounces nominal, 64 ounces liquid maximum | Neither package increases the documented liquid batch ceiling. |
| Travel cups | 2 x 24 ounces | 1 x 24 ounces | TB301 is the fuller package for two independent take-away drinks. |
| Thick-blend vessel | No dedicated tamper bowl | 14-ounce bowl with built-in hand-turned tamper | SS351 gives you a way to move thick ingredients toward the blades in the small vessel. |
| Dough tool | No dough blade included | Dough blade included | SS351 adds a dedicated mixing attachment to its main pitcher. |
| Automatic controls | BlendSense load adjustment | 6 Auto-iQ programs | These are different control approaches, without a demonstrated texture advantage here. |
| Disc slicing and shredding | No included disc | No included disc | Neither package replaces a processor equipped for uniform disc slicing. |
What you give up
Recommendation switch
Choose Ninja Detect Duo Power Blender Pro. TB301 includes two 24-ounce cups.
Choose Ninja Foodi Power Blender and Processor System. SS351 supplies the 14-ounce bowl and its built-in tamper.
Choose neither. Neither selected package contains that disc setup.
What matters in practice
The main pitchers have identical stated capacity limits, so they do little to separate these bundles. Two travel drinks point toward TB301. A spoonable frozen bowl and one drink point toward SS351 because the supplied containers match those different tasks.
SS351's processor work happens inside the main pitcher with its chopping and dough blades. It is useful for those operations, but it does not include the feed chute and disc needed for repeated slices or shreds. Check the recipe task rather than relying on the word processor.
TB301 can adjust its blending cycle to the load. SS351 provides preset Auto-iQ cycles and manual control. Ingredient preparation, liquid quantity and vessel loading still matter. The published controls alone cannot tell us which will make a smoother drink in your recipes.
