The Blendtec Stealth is, without question, the quietest blender I have ever reviewed. For the past week, I’ve had the pleasure of testing it out in my kitchen and am simply amazed by what it can do, and how quiet it can do it.
The Stealth was originally designed for use in commercial settings like restaurants and coffee or smoothie shops, where a low noise level is important. But, Blendtec has recently released it for sale to the general public, and if you’re looking for the same blender the pros use, this is it!
The Blendtec Stealth is incredibly powerful. Inside the specially engineered black plastic base is a 3.8 peak horsepower motor. A clear plastic sound enclosure is attached to the base which, when closed, dramatically reduces the noise.
The difference is amazing! Hear for yourself in this short video.
It measures 17.3″ tall, 8.3″ wide, and 9″ deep, making it just a bit shorter than even the shortest Vitamix blender. The Stealth weighs 16.2 lbs meaning that it is also the heaviest blender we’ve ever reviewed.
The cord is 6’8″ (80″) long, but unfortunately, there is no place to store it if don’t need to use much of it. You’ll be left to coil it up and hide it behind the base.
Included in the Stealth package are two jars, the WildSide and the Twister, a user guide, and a Twister Jar recipe book.
The WildSide Jar
The WildSide jar included with the Stealth has a capacity of nearly 90 fluid ounces and the jar has very clear markings on the side for up to 36 ounces which makes measuring very easy.
The WildSide has a unique, five-sided design that helps to create a vortex, which will pull ingredients down towards the blades. The flat-sided, square designs make it much easier to scrape out thicker mixtures and extremely easy to clean, unlike the standard Vitamix containers that are much more narrow.
One important thing to note about this and all Blendtec containers is that the blade used is a two-pronged, wingtip design. The wingtips do an excellent job of breaking up larger ingredients allowing them to be blended quickly, and the two-pronged design makes it easier to scrape out the final mixture.
It comes with a vented Gripper® lid that allows pressure and steam to escape when blending hot soups or sauces and the opening in the middle lets you add ingredients while blending.
The Twister Jar
Blendtec’s newest jar, the Twister Jar is also included as part of the Stealth package. It is specially designed for thick mixtures like hummus, nut butter, or dough and comes with a two lids, one of which has blades that extend down the walls of the container.
When this lid is twisted, it will scrape ingredients away from the sides and force them back down into the blades. It also comes with a Spectacula Spatula which really helps to scrape the finished mixtures from the jar when finished.
I tested out the Twister Jar by making pesto, almond butter, and spinach pasta, shown here. Each time, it did an excellent job, and the special twister lid was excellent at moving ingredients away from the walls of the jar and back down into the blades.
One thing to note about the Twister jar is that the Twister lid does not make a tight seal with the container. This is important because it is possible for the ingredients to come out through the gaps between the lid and the container as shown by this image that was the result of my first attempt at making almond butter.
It is important when using the Twister jar and lid, to make sure that the blender is started at a very slow speed, and then gradually ramped up to full speed.
As mentioned previously, the Blendtec Stealth is the most powerful blender we’ve ever reviewed. It comes with a 3.8 peak horsepower motor, which is more than enough to take on anything that you can throw at it. The motor is rated at 1800 watts making it nearly 2.5 times more powerful than any standard blender.
The motor is extremely quiet considering how powerful it is. At high speed, it makes very little noise. All of this power means that the Stealth makes quick work of heating up a soup. The friction created by the liquid and the blades is impressive. In my tests, I was able to heat up soup in only 3 minutes! I mistakenly ran the automatic soup cycle (which lasts for only 90 seconds) twice, and the soup was hot enough to burn my tongue!

The controls on the Blendtec Stealth are very advanced. It comes with an Illuminated capacitive touch control surface with a manual speed slider, and it is very customizable. The blender comes with 42 preprogrammed blend cycles and even has a USB port that allow you to create custom blend cycles using their Blend Wizard™ tool.
The preprogrammed blend cycles include: small slushy/milkshake, granita/medium milkshake, small milkshake, milkshake with frozen fruit, small margarita/ice cappuccino, medium smoothie (4 different variation), large ice cappuccino, salsa, large smoothie (6 variations), large milkshake (3 variations), 50 seconds @ speed (1, 2, 3, 5, 7, or 9), pulse @ speed (1, 2, 3, 5, 7, 9), batter, ice crush/milkshake, ice cream, whole juice, soup, or ultrathick smoothie (4 variations).
It is very easy to reprogram any of the six main presets with these settings.
If you’d prefer to control the Stealth manually, it also has that option. To access this control mode, you need to tap the setting toggle button on the left below the power button, and it will reveal a slider control. The slider allows you to select and change to any speed. It will then continue to run until the cycle is canceled by tapping the red X on the right side of the control panel. You can also pulse the motor by tapping the button with the pulse icon, located below the cancel button.
The Blendtec Stealth is truly a commercial-grade blender and it has a price to match. Priced at $1,499, this is the priciest blender we’ve ever reviewed, but it is well-worth the money. It is amazing how quiet this blender is when compared to other high-performance blenders.
The innovative sound dampening features, incredibly powerful motor and ability to customize the blend cycles is something you would normally expect to find in premium smoothie shops or restaurants, but now, you can have it in your kitchen.
