Emptying a bag of frozen strawberries and a handful of kale into a blender only to hear the motor groan and stall is a quick way to ruin a morning routine. I’ve spent years navigating the “Ninja ecosystem,” and two of their heavy hitters always seem to spark a debate: the classic Ninja BL770 Mega Kitchen System and the modern Ninja SS401 Foodi Power Blender Ultimate System.
The BL770 has been a countertop staple for nearly a decade, known for its sheer size and “crush anything” attitude. On the other hand, the SS401 represents the new school of Ninja engineering—focusing on variable speed control, specialized smoothie bowl tools, and a more intelligent motor. After a week of making everything from thick almond butter to shredded carrots and pizza dough, I’ve found that while both carry the “Blender & Food Processor” title, they offer two very different paths to a finished meal.
The Key Difference: smartTORQUE vs. Total Crushing
The fundamental key difference between the Ninja SS401 and the BL770 lies in the motor technology and the specialized attachments. The Ninja SS401 features a 1600-Peak-Watt Power Dense Motor with smartTORQUE, which is specifically engineered to maintain high speeds under heavy loads without stalling—perfect for thick nut butters or smoothie bowls. It also includes an XL Smoothie Bowl Maker with a built-in tamper and a food processor lid with a feed chute and slicing/shredding discs.
The Ninja BL770 utilizes a 1500-Watt motor and relies on the “Total Crushing” stacked blade system. While it is incredibly powerful for turning ice into snow, it lacks a feed chute for the food processor (it uses a closed 8-cup bowl) and does not include slicing or grating discs. Essentially, the SS401 is a precision culinary tool with advanced processing capabilities, while the BL770 is a high-volume “crushing” workhorse.

Detailed Comparative Review: My Experience
To get past the specs and into the real-world utility, I decided to push both systems to their absolute limits. I was looking for the small details that make a big difference: which one rattles the dishes on the counter, which one screams the loudest, and which one actually produces a silky-smooth puree without needing a break. This isn’t just a numbers game—it’s about which machine makes your time in the kitchen feel effortless versus which one makes you work for your results.

Design and Footprint: Sleek vs. Sturdy
The Ninja BL770 is a big machine. It feels like it was built for a high-volume catering kitchen. The base is wide, and the black plastic gives it a very industrial “old-school Ninja” look. It’s taller, too—at over 18 inches, it barely cleared the space under my kitchen cabinets.
The Ninja SS401 feels like the “next generation.” It’s slightly more compact but feels more “dense.” The platinum finish is a nice touch, but the real star is the control panel. Instead of just basic buttons, it has a dial for variable speed control. This allowed me to start my blends slow to incorporate ingredients before cranking it up to full power, something the BL770 just can’t do with its “all or nothing” manual buttons.
Blending Performance: The “Stall” Test
I attempted a “thick” test: a frozen acai bowl with very little liquid.
- The BL770 struggled here. Because it uses a stacked blade system in a wide pitcher, the frozen fruit often got stuck at the top, creating an air pocket around the blades. I had to stop the machine three times to move things around with a spatula.
- The SS401 sailed through. The XL Smoothie Bowl Maker has a built-in tamper—a little handle you twist while it’s blending. It pushes the frozen ingredients back down into the blades constantly. Coupled with the smartTORQUE motor, it never slowed down. If you want that spoon-thick, soft-serve consistency for your bowls, the SS401 is the clear winner.
- ENHANCED FOOD PROCESSING: The enhanced processing lid with feed chute and select-cut processing discs allow for precise shredding, slicing, and grating.
- NEVER STALL AGAIN: Crushing blender with 1600-Peak-Watt Power Dense Motor and smartTORQUE to power through and never stall.
Food Processing: Precision vs. Bulk Chopping
This is where the machines diverge completely.
The BL770 comes with an 8-cup bowl, but it only uses a chopping blade or a dough blade. It’s great for making salsa or pizza dough (it handled a 2lb dough ball easily), but you can’t slice a cucumber or shred a block of cheese in it.
The SS401 actually functions like a high-end standalone food processor. It has a feed chute lid and reversible discs. I was able to shred a block of mozzarella in seconds and slice potatoes for a gratin. The “Select-Cut” processing is a massive leap forward for this combo system. If you want to eliminate an extra appliance from your counter, the SS401 actually replaces a food processor, whereas the BL770 just mimics one.
Noise and Stability
Let’s be honest: both of these are loud. They are Ninja blenders, after all. However, the SS401 has a higher-pitched, more mechanical whine, while the BL770 has a deep, roaring rumble. Because the SS401 has the smartTORQUE motor, it sounds more “consistent.” The BL770 tends to vibrate the counter a bit more when it’s crushing heavy ice, making me want to keep a hand on the lid just in case.
Ninja SS401 Foodi Power System
- ENHANCED FOOD PROCESSING: The enhanced processing lid with feed chute and select-cut processing discs allow for precise shredding, slicing, and grating.
- NEVER STALL AGAIN: Crushing blender with 1600-Peak-Watt Power Dense Motor and smartTORQUE to power through and never stall.
Pros:
- Ultimate Versatility: The slicing/shredding discs and feed chute make it a “real” food processor.
- No-Stall Blending: smartTORQUE is genuinely impressive for nut butters and thick dips.
- Built-in Tamper: The smoothie bowl maker solves the “air pocket” problem forever.
- Variable Speed: More control over textures than the older button-style models.
Cons:
- Complexity: There are a lot of parts and lids to store.
- Price: It is generally more expensive than the legacy BL770 system.

- POWERFUL 1500-WATT MOTOR: Crush ice, blend frozen fruit, and power through tough ingredients with the 2-horsepower motor, designed for professional results.
- TOTAL CRUSHING TECHNOLOGY: The XL 72-oz.* pitcher, ideal for large batches and entertaining, features Total Crushing Blades that crush ice to snow in seconds and...
Pros:
- Ice Crushing King: The stacked blades are still the best for “snow” consistency ice.
- Simplicity: Very few parts to keep track of; straightforward manual buttons.
- Proven Durability: This model is known for lasting years under heavy use.
- Value: Often the most power you can get for the price in a combo set.
Cons:
- Limited Processing: No slicing or shredding; you can only “pulse” chop.
- No Tamper: Requires frequent stopping and scraping for thick recipes.
- Height: Too tall for some cabinet setups.
The Final Recommendation: Which System Wins?
I recommend the Ninja SS401 if you are looking for a true “all-in-one” kitchen replacement. If you bake, make smoothie bowls, and need to slice or shred vegetables for salads and stir-fries, this machine is lightyears ahead of the older models. The variable speed and the smartTORQUE motor make it a more sophisticated culinary tool.
I recommend the Ninja BL770 if your needs are simpler. If you want a beast of a machine that can make a massive pitcher of margaritas for a party, crush ice for snow cones, and occasionally mix a batch of cookie dough, the BL770 is a reliable, powerful classic that won’t let you down.
In my kitchen, the Ninja SS401 is the undisputed champion. The addition of the slicing discs and the built-in tamper for smoothie bowls fixed every frustration I had with the older BL770 design.

Frequently Asked Questions (FAQs)
Q: Can I use the SS401 discs in the BL770?
A: No. The motor bases and the bowl designs are completely different. The BL770 does not have a drive shaft designed to support slicing discs.
Q: Which one is better for making hot soup?
A: Neither. Like most Ninja blenders, these use friction and high speed, but they do not have a heating element. Also, you should never blend hot liquids in Ninja pitchers as the pressure can cause the lid to fly off.
Q: Is 1600 watts much more powerful than 1500 watts?
A: On paper, no. But the “smartTORQUE” technology in the 1600W SS401 manages that power better, meaning it feels much stronger when the blades are being slowed down by thick ingredients.
Q: Are all parts dishwasher safe?
A: Yes, both models feature BPA-free, dishwasher-safe pitchers, bowls, and blades. I always recommend the top rack for the lids and blade assemblies to preserve the seals.
