Mueller Ultra-Stick vs Vitamix 5-Speed Side-by-Side Comparison

Pureeing hot soup wasn't challenging the Vitamix thanks to its powerful motor and razor-sharp blades. Although it wasn’t any faster than its counterparts in pureeing time, it warranted the higher cost by providing us with a nutrient-dense purée of silky smooth texture. It also stood out from the rest with a non-suction performance that helped keep splashing to minimal.  

Indeed, the Vitamix is the most suitable hand blender for preparing restaurant-quality soup at home. It’s a great bargain for any recipes that involve fibrous food, too. If you’re now looking for a tool that can consistently ensure the smoothest blends, we particularly love and recommend this blender.

Despite being a low-priced blender, the Mueller Ultra-Stick wasn’t any slower than the others we tested. It took about 30 seconds to yield two servings of pureed soup packed with carrots, pumpkin, and parsley.

That said, it wasn’t so good at drawing ingredients toward its blades, so we needed to move it around for an even blend. Moreover, it sucked tightly to the pot’s bottom, which didn’t cause as much spatter as the Cuisinart, but did cause small scratch marks on our cookware’s surface. It also made it very challenging for us to stir with the blending wand.

Our Mueller soup’s texture was acceptable but not the silkiest; there were still several large chunks of veggies left behind.

The Vitamix took only 1 minute and 5 seconds to complete this test. By comparison, its counterparts such as the UTALENT 5-in-1 and the Hamilton Beach 2-speed required nearly double the time. 

Regarding the smoothie’s texture, of all the blenders we tested, only the Vitamix could churn out a thick, creamy smoothie with almost no solids left behind. Plus, despite being longer and heavier, it operated well in our 24-oz blending jar while the BPA-free plastic bell guard helped prevent scratches on the jar’s surfaces.

To ensure this portable machine can do the work of a full-sized blender for making smoothies, we designed this specific test for it. We would award it corresponding points if it could create a homogeneous mixture of just kale and frozen fruit. Disappointingly, we found that the Mueller Ultra-Stick isn’t great at blending solid fruit and leafy vegetables. 

In this task, it had a very hard time breaking up the ingredients. This caused it to demand up to 1 min 15 secs to finish the test. 

And although the Turbo mode is intended to give the blender ​​an extra boost at max speed, we noticed the speed increment wasn’t enough to make any difference. Our smoothie came out pretty smooth, but there were many unprocessed chunks of mango. It was also a bit grainy due to a mass of tiny leafy bits. For about $35 more, you can upgrade to the better Braun MultiQuick-5.

As this blender shouldn’t run for longer than 60 seconds at the time to avoid damage, we took a break after 30 seconds. In the meantime, we used a spatula to dislodge the food that lodged in the blade guard.

In this test, most of the blenders produced acceptable outcomes and only our culinary expert could tell the differences between them. However, the Vitamix didn’t have the fastest performance, requiring about one minute and forty seconds to incorporate all the ingredients. This was around 30 seconds slower than the winners, including the Cuisinart Smart Stick, KOIOS 4-in-1, BELL 10-speed, and Chefman cordless. 

This is because when the mayonnaise emulsified and started to thicken, the blending wand generated a suction force, pulling itself against the container’s bottom. That made movement more difficult and slowed the whole process down. We don’t necessarily consider the time to be a deal-breaker. Since the blender itself is quite heavy, though, the longer the process takes, the more it will fatigue your hands. 

In conclusion, despite this drawback, the Vitamix is an acceptable alternative to a hand mixer for preparing mayonnaise or other emulsified sauces. Still, it is not the best hand blender for this job and ideal results may require extra effort.

Although the Mueller’s whisk attachment has thin, floppy wires, it got the job done in less than two minutes. That was 10 seconds faster than the Braun, whose whisk is more sturdy and springy. It was nearly as fast as the high-end Vitamix and handily beat the cordless KitchenAid by a full minute.

It was also easier to clean. For the most part, its mayonnaise tailings rinsed off easily under our running tap. Using the blending shafts, on the other hand, caused the food to get clogged in the blade housing. As such, it was very challenging for us to scrub off the residuals on the blade’s backsides.

The Vitamix took just 40 seconds to yield one serving of drinkable almond milk.  

That said, from start to finish, its crushing process didn’t go very well. The almond skins, along with peeled chunks, became lodged in the blade guard. We had to stop the blender temporarily and use a spatula to dislodge the food, which we didn’t have to do with other models, such as the Braun MultiQuick-5.

Not only that, but because the Vitamix couldn’t create a consistent vortex, everything got close to overflowing when we increased the speed. 

Suction was a problem again as well. As a result, we got some almond spatter when we tried to lift up the wand. Most of the splatter-related issues could probably be avoided, though, if we blended it in a taller or larger jar.

Grinding raw nuts shouldn’t be a challenging task for any hand blender. However, our Mueller couldn’t perform any worse, though part of the reason is due to our blending jar — its small size caused the liquid to overflow all over the countertop every single time we moved the blender. So if you intend to use this blender to prepare watery drinks, it’s best to use a bigger container. 

None of the blenders we tested could avoid suction, but the Mueller’s was so strong that it was hard to stir or withdraw the wand, and when we lifted it up the container came with it. These things caused the liquid to easily overflow.

Not only that, but this blender didn’t grind finely enough for a creamy drink. Our almond milk was drinkable, but quite watery and not as sweet as others.

The Vitamix could be a great all-around blender if it included a whisk attachment. This is because, in our test, there was no way the immersion blender could beat egg-white with its ordinary blending shaft. Unlike a whisk attachment, the blending shaft can’t force air into the egg whites, which is the way to create an even, bubbly foam. Consequently, the result was a cloudy liquid with two separate layers of bubble film and eggy water. We awarded it no points for this test.

Before we began this test, we presumed that all the whisk attachments would perform well at  beating egg-whites, though some may be more efficient than others. Surprisingly, Mueller's performance proved us wrong.

First, it had an advantage over the blending wand in incorporating enough air into the egg whites, allowing the egg-protein to form a stiff, airy foam. What was until its motor seriously overheated several times, requiring us to let it stop and cool down. This issue didn’t regularly occur with the other blenders, and spending so long with the Mueller was tiring.

Even worse, after this test the whisk attachment had lost its original bulbous shape. The strands of looped wire were all out of their initial order, which would impair its performance in the next emulsifying and beating tasks.
