Blenders aren’t just for smoothies anymore—they’ve become all-in-one kitchen helpers. The Ninja CL401A and Ninja BN401 are two popular options from Ninja that promise fast blending, sleek designs, and enough power to handle anything from frozen fruit to nut butter.
At first glance, they seem similar, but they’re built for very different types of home use. One leans toward full-sized, multi-function blending for families, while the other focuses on quick, personal servings on busy mornings.
To help you choose the one that fits your kitchen best, I’ve gone through their specs, reviews, and real user feedback to see which model actually delivers on its promises.

Ninja CL401A vs BN401: Similarities
Powerful Motors
Both the CL401A and BN401 come with strong motors that can crush ice and blend frozen fruits with ease. The CL401A has a 1100-peak-watt motor while the BN401 is close behind with 1000 watts, so both can handle thick smoothies, nut butters, or sauces without stalling.
Auto-iQ Programs
Each blender features 2 Auto-iQ preset programs that run timed pulsing and pausing patterns. This takes the guesswork out of blending and gives consistent results every time. Just press a button, and the machine does the rest.
Pro Extractor Blades
Both models use Ninja’s Pro Extractor Blades, which are designed to break down whole fruits, vegetables, and seeds. This helps release nutrients from ingredients and creates smooth, even blends without chunks.
To-Go Convenience
Each comes with to-go cups and spout lids so you can blend directly in the cup and head out the door. This makes them ideal for quick breakfast smoothies or post-workout shakes when you’re in a rush.
Compact Design
Both blenders are compact and lightweight, fitting easily on small countertops or even in cabinets. They’re built for personal use, so they won’t take up much space even in small U.S. kitchens or dorms.
Easy to Clean
All parts on both models are dishwasher safe, and the blade assembly removes for a quick rinse. Users often mention how cleanup takes less than a minute, which is a big plus for busy mornings.
Versatile Use
Despite their small size, both blenders handle a variety of tasks beyond smoothies—like sauces, dips, dressings, and frozen drinks. This versatility makes them handy for everyday kitchen prep.
Single-Serve Focus
Both blenders are designed as personal, single-serve systems. They’re not full-size countertop blenders, so they’re perfect for individuals or small households who make one or two drinks at a time.
One-Touch Simplicity
Each has simple, intuitive controls. Whether it’s the Auto-iQ buttons or push-to-blend design, both are built to be quick and foolproof—ideal for early mornings or on-the-go lifestyles.
Recipe Inspiration Guides
Both models come with a 20-recipe inspiration guide. This helps new users get started with smoothies, frozen drinks, sauces, and more without needing to experiment.
Stability During Use
User feedback mentions that both have sturdy bases that don’t wobble while blending. The suction cup feet help keep them steady even during high-speed blending.
Ninja CL401A vs BN401: Differences
Motor Power
The CL401A runs on a slightly stronger 1100-watt motor, while the BN401 has a 1000-watt motor. In daily use both are powerful, but the CL401A has a bit more torque for tougher blends like thick nut butter or frozen fruit.
Cup Capacity
The CL401A comes with larger 32oz single-serve cups, while the BN401 includes 24oz cups. The CL401A is better for big servings like meal replacement shakes, while the BN401 suits smaller portions or lighter smoothies.
Dimensions and Footprint
The CL401A is a bit wider and shorter, while the BN401 is taller and slimmer. The CL401A takes slightly more counter space but holds more, while the BN401 is easier to tuck into tight spots or small cabinets.
Weight
The BN401 is heavier at about 6.3 pounds, while the CL401A is lighter and more portable at around 1.5 pounds. If you move your blender around often, the CL401A is easier to lift.
Branding and Market Focus
The CL401A is sold under a “Generic” listing on some marketplaces and is less widely available, while the BN401 is an official Ninja model with massive popularity and over 50,000 reviews. U.S. buyers will find the BN401 easier to find, replace, or return.
User Feedback Volume
Because the BN401 has been on the U.S. market longer, it has far more user reviews and proven reliability. The CL401A has only a few reviews so far, making it harder to judge long-term durability.
Price and Availability
The CL401A is often listed at a higher price despite its simpler setup, while the BN401 is usually more affordable and widely stocked. For most buyers, the BN401 is easier to get on sale.
Design Details
The CL401A cups have a more basic spout lid design, while the BN401’s lids include a magnetic locking cap and better sealing to prevent leaks. The BN401 base also has stronger suction feet for added stability during Auto-iQ cycles.
Build and Accessories
The CL401A includes two 32oz cups, while the BN401 comes with two 24oz cups. The BN401 package is slightly more refined, with better-quality lids and a sturdier overall build. Users mention the BN401 cups feel thicker and seal tighter.
Noise Levels
Reviews mention the BN401 is loud, but the CL401A hasn’t received much feedback yet. Because of its slightly stronger motor and lighter build, the CL401A may vibrate more and be a bit noisier, though this isn’t widely confirmed due to fewer reviews.
Market Reputation
The BN401 has a strong track record in the U.S. with thousands of positive reviews and Amazon’s Choice badge, while the CL401A is still new and has only a handful of reviews. This makes the BN401 a safer bet for long-term reliability and support.
Cleaning Experience
Some BN401 users noted gunk buildup under the blade gasket if not cleaned deeply, while no such reports exist yet for the CL401A. This may be due to higher user volume for the BN401, but it’s a known point for regular deep cleaning.
Safety & Stability
The BN401 has a heavier base and suction feet that keep it stable during Auto-iQ cycles. The CL401A is much lighter, so it may shift slightly on smooth countertops when blending thick mixtures.

I would personally recommend the Ninja BN401 because it’s a proven, reliable choice with thousands of positive reviews from U.S. users. It blends fast, makes smooth drinks every time, and has sturdy cups with leakproof lids—perfect for daily use or busy mornings.
