Soup and Smoothies: Nutribullet RX Review

The Nutribullet Rx is Nutribullet’s latest blender offering. It features a more powerful motor than the Nutribullet or the Nutribullet 900 and it adds a heating function for making hot soup. The soup feature is something that people have been asking for, so that addition makes the Rx a rather attractive option. Nutribullet Rx reviews, however, have been a bit mixed because of complaints about the rubber gasket on the blade housing coming loose. There have also been reports of the soup pitcher leaking. Curious about that, I went out an purchased one, even though the last thing I need is yet another blender! So, here is my Nutribullet Rx review. I give it an overall rating of a B. It is a good blender, and I like it better than my 900 model, but it is not without some faults.

Bring on the Power: The Nutribullet RX Motor

The best feature of the Rx is that it has a 1700 watt motor, which is a significant step up from the 900 model. This allows for excellent blending, especially for greens. No more little chunks of spinach or kale in your smoothies with this baby!  While I have been happy with the performance of the Nutribullet 900 in that regard, the Nutribullet Rx is definitelys a step up. It also takes care of greens better than my Vitazmix. One small complaint though: With the bigger motor, also comes greater noise. I don’t really expect a blender to be quiet, but if you want a bit less racket and don’t intend to make soup, get the 900 instead. Also, if you make soup be prepared to listen to this noisy thing for 7 minutes!

Design Changes

The Nutribullet Rx features some design changes that make blending a bit more efficient. Frozen items do not get stuck in the blades as easily, and it comes with nicely large cup sizes of 30 and 45 ounces (the previous Nutribullet model cups are not compatible with the Rx). The unit crushes ice wonderfully, and it is no surprise that it makes excellent smoothies and pulpy juices. That is what the brand is known for after all. I also found using it that it was a bit more forgiving of accidentally overfilling it. Things would still blend without having to remove the bullet and shake it or tap it get things unstuck from the blades.

Also new is how the unit turns on and off. To turn it on, you simply place the bullet in the motor and it starts automatically.  No more pushing and turning, which is nice since my 900 would sometimes stick doing that. The Rx turns itself off after an appropriate amount of time. If you push the button on the front within the first minute, it goes into heated soup mode. It also does a cool little decrease in motor speed in the middle of the cycle, which helps dislodge anything that might be stuck around the blades. However, the gasket now comes dislodged easier as well, which is a problem, although not an insurmountable one. More on that gasket in a bit.

Heating Fnction:  Nutribullet Soup

For many, the biggest and happiest new feature of the Nutribullet Rx is the heating finction and one liter pitcher, which allows you to make hot soup and sauces. I had  previously considered using my Nutribullet 900 for soup and then heating it separately, but even the colossal cup size for that was a bit on the small side, and I already have a Vitamix that I could use for heating (the Vitamix heats by energy emitted from the blades, without a set timer function and it does a pretty good job at it). With the Nutribullet RX, soup is easily done in one step, and the entire unit is much more portable and compact than the Vitamix. Given my love of soup, you can expect to see Nutribullet soup recipes on the site pretty soon.

Soup making is quite simple, but there is a big caution that must be taken. Don’t overfill the pitcher! Like the cups, the pitcher has a max line. I interpreted it to be like the cups, where you can fill the cup quite full and then add liquid to the line. With soup, that overfills it and, as it blends, soup rises up through the lid vent and leaks out all over the sides of the pitcher. I made quite a gooey green mess making my first batch of Nutribullet broccoli soup! Luckily I snapped my photo just before it made a mess! I have read a fair number of Nutribullet Rx reviews that mention leaking when making soup, and I am guessing they had the same issue. The fix, of course, is to be quite conservative when filling the pitcher. Although that in turn makes it hard to get two full bowls of soup out it. Ideally, I think the pitcher needs to be a bit larger for making soup for two people.

By the way, you can also fill it fuller and deal with leaks by wrapping a paper towel around the top. That actually worked very well for me, although it is annoying to have to take that step.

One final note on soup making: Soup in the Nutribullet Rx can come out a bit frothy. Or at least my broccoli soup did. This was likely partially because I put some skim milk in it and all that heating and blending foamed it a bit. It wasn’t unpleasant, but it was a bit unusual! I jokingly referred to it as broccoli latte.

Clean Up

Given the mess I made the first time I made soup, I learned quickly about cleaning the Nutribullet Rx. It really is quite simple. The unit has drain holes, so when you drip green broccoli goo into the base, you can just pour a bit of warm water in there and clean it up. It was very easy! The cups and soup pitcher are dishwasher safe, but the blade unit should be washed by hand and the motor unit should not be submerged in water.

About That Pesky Nutribullet Rx Gasket

Now for the biggest complaint. In general, Nutribullert Rx reviews have been quite positive. Simply take a look at the customer reviews on Kohls or Amazon to get an idea. But one complaint jumps out repeatedly. It seems that a fair number of people have trouble with the gasket on the blade housing coming loose or falling off completely. That in turn causes leaks and performance issues. For some, the gasket came off while blending and got mangled in the blades.

There also is a reported fix that I have mixed thoughts on. The Nutribullet RX comes with a blade removal tool. The instructions are not particularly upfront about the use of it. In fact they never really tell you to use it at all and the instruction discuss hand tightening. But there are reports that those who use it every time have not had gasket problems. OK, that would good, and I like the tool since I used to have problems with my 900 getting stuck on too tight at times. But, I have been using the tool and I too have had the gasket fall off.

Here is the handy dandy blade removal tool:

Nutribullet Rx Blade Removal Tool

I find that the gasket seems to come off most often when blending using frozen fruit. I have never had it fall off while blending, but it has sometimes popped off when I removed the blades, even using the blade removal tool religiously. This hasn’t really been a big deal to me. The gasket sometimes came off with my 900 as well and it isn’t all that hard to pop back on. I have seen some people say that they had difficulties with that, but I haven’t. I think it goes back on very easily and much easier than the 900 one. Now, if it comes off during blending and gets mangled, I will change my view of it, but so far that has not happened to me.

One final note, and another way to prevents this: You can always make smoothies in the soup pitcher and just hand wash the whole thing, leaving the blade unit on. This is what I have taken to doing simply because I never use the Nutribullet cups as drinking cups and I can just leave the whole thing on my counter like a normal blender that way. So for me, that soup pitcher is a big bonus when it comes to making smoothies!

Nutribullet Rx

Final Conclusions

Overall, the Nutribullet Rx is a step up from the Nutribullet 900 Pro. The larger motor is awesome, and the ability to make soup is a welcome addition. However, it can leak out the top when making soup and the gasket can come dislodged. If Nutribullet would alter the design to include a bit larger soup pitcher and figure out how to fix the gasket issue, I would give it an A, but because of those two problems, I rate it a B. That said, I would rate my Vitamix the same and I like the Rx better than the 900.  So if you are trying to decide between Nutribullet v Nutribullet Rx, I recommend the Rx. When it comes to Nutribullet v. Vitamix, it gets tougher to choose. I’ll write a whole post up on that one soon!

You can buy the Nutribullet Rx at Kohls or Amazon, plus quite a few other department stores and big box stores carry it. I picked mine up in person at Target.

  1. Hi! This is my first time trying out Nutribullet Rx. It is a very powerful machine but I have a question. When I put all fruit ingredients in the cup and let Nutribullet’s smart technology decide how long the machine should run. When it stopped, the liquid in the cup was warm. Why? Is there a way not to make warm smoothie? Thanks.

    • Hi! Are you pushing the button that turns on green by any chance? If so, that puts it in soup mode and will heat the ingredients. You should just put the cup on and let it go. If you are not pushing that button, it really shouldn’t be heating your ingredients much. All blenders do generate some heat, so if all of the ingredients are at room temperature perhaps they could get slightly warmed. I have had dressings get warm that way before. The solution is to use chilled ingredients or add a few ice cubes (which I like for texture too). Other solutions are to lift the cup off before it is done. I do that a lot because honestly, it rarely needs to go as long as it does. You can also use froze fruit which makes a very nicely chilled smoothie.

    • I use frozen fruits! it keeps it cooler 😉

  2. My husband recently bought the Rx and I have noticed that it doesn’t blend my frozen strawberries. So, instead of making my smoothies in the almost $200 machine I have resorted to using the blender that I already had. I use frozen fruits for smoothies and I am disappointed that it’s not working for me. Solutions or Answers to what could be the issue.

    • Hi Arlene! I regularly make smoothies in my Rx with frozen fruit, including huge frozen strawberries from Costco (those tend to be particularly large) and I have never had a problem. I have even made ice cream from frozen fruit using less liquid, although that requires stopping and stirring sometimes. You shouldn’t have a problem with a standard smoothie using frozen fruit as long as you are using enough liquid. I suggest that you try filling the cup not quite as full so that you have a bit more extra liquid when you add your liquid to the fill line and see if that helps you. Frozen fruit smoothies definitely do need the right amount of liquid. If you find the blender getting stuck, you probably don’t have enough liquid. Another thing you can try is making your smoothies using the soup pitcher. I do that all the time simply because I never use the Nutribullet cup as an actual cup. Using the pitcher allows you to “cheat” on the liquid better by adding a bit extra. With the cups, you definitely don’t want to go over the fill line or you can get leaks. If you still have issues, I would start to suspect that you got a defective machine with a motor that is not running strong enough. At that point I suggest contacting the manufacturer. The Rx definitely should handle frozen fruit just fine.

      • That’s interesting because mine also doesn’t blend frozen fruit. I use a cup of liquid to half a frozen banana and i always still have frozen banana and a warm smoothie which drives me crazy. I don’t press the green button and after getting a warm smoothie the first day double checked it was green the next day.

        I was also disappointed in the soup function. I think it is exaggerated. As someone else said you still need to cook before putting it in. I could do that with my stick blender.

        • Frozen fruit should blend just fine. I use frozen bananas all the time in mine, along with other frozen fruit. Try cutting up your banana before you freeze it, a whole one might be a bit much for the machine, and make sure that you are filling with liquid to the fill line.

  3. I just received my RX, and must admit, I am disappointed in the soup recipes. It calls for cooking ingredients in a pot, BEFORE putting them in the RX. I want soup recipes that use the RX only.

    • As long as you are not adding meat, you can make quite a few soup recipes without precooking. I normally just put in my ingredients and run them for the full soup cycle. Everything gets sufficiently heated. I tend to make broccoli soup and tomato soup quite a bit. I do like to precook my broccoli if it is fresh to soften it up more or use frozen broccoli that has been thawed (that is always already pretty soft). I have been meaning to put more soup recipes up on the site. I’ll make that priority after the first of the year!

  4. What happen to the superfood to add to soups?

  5. I TOO HAVE A GREAT BLENDER I USE FOR SMOOTHIES AS I USE ICE CUBES AND IT CRUSHES ICE JUST GREAT..CAN I REPLACE WITH NUTRIBULLET RX..CANT FIND ANY INFO IN INSTRUCTIONS.

  6. Hello Carleen, I have the original nutribullet system which I love and just received the Rx system. The soupblaster attracted me because I have very little time in my work schedule and was surprised to find the soup recipes requiring cooking them first. I was hoping to throw carrots, squash or any of the vegetables into the soupblaster and have it extract them like my old system but with the heated function. Is this possible and will there be recipes posted soon that doesn’t require precooking?

    • Hi Dawn! I have noticed too that many Nutribullet Rx recipes for soup require precooking. In many cases that is to assure that the soup is creamy or to otherwise improve consistency, but a lot of those recipes can be done without precooking. For example, a blend with a decent amount of softer veggies, such as zucchini, tomatoes, cucumber etc. mixed with some harder veggies such as broccoli, carrots, peppers etc. could come out just fine blended raw in the soup mode. I did once try to make broccoli soup without pre-steaming it though and I was not a fan of the consistency. On the other hand, I have made tomato soup without precooking anything (I plan to get that recipe up soon). I also have been experimenting with a cream of mushroom soup without precooking. One of my plans for the next year is to include a lot more soup recipes, and I hope to include more that don’t require cooking items first. You are not the first to request that, so it seems like it is something that people are looking for!

  7. Hi Carleen

    I just bought an Rx to give to my mom in the Phils. but our voltage there is 220. Is it ok if just use a transformer since the machine runs in 110?

    thanks

    Carleen – great blog.
    I am new to the “NutriNation”, so forgive what may seem like a dumb question. Do the solid measurements (e.g. 1 cup of cucumber) use solid measures, or liquid? I have assumed the liquid, but with those measurements, I’m finding that the recipes in the Rx book, which generally say to use the short cup, barely fit in the large cup. And the servings are pretty big. If you could shed a little light…

    Thanks,

    • Hi! Solids are measured as solids. The problem tends to come up because people rarely actually measure things for their recipes, So when a person sends me a recipe, often they have “guestimated” the amount. I would think the official Nutribullet recipes books would be better on that, but I can see how it can get off. If you find that a recipe is off, I suggest taking the measurements as suggestions and just fill your Nutribullet cup with a mix of the ingredients that the recipe calls for. The beauty of blending is that there isn’t really a right or wrong when it comes to proportions of the solid items. You do always need to be sure that you add liquid to the fill line though.

  9. I got 5 nutribullet rx and every one I give it to as gifts complains about how worm fruits. Or veg how warm it was and they did not have it on soup..I’m saying the same thing I’m drinking my fruits warm.

    • To get ice cold drinks try using frozen fruit or add ice to the Nutribullet. You can also make smoothies ahead of time and refrigerate them.

  10. I received my Nutribullet Rx a few months ago and stopped using it because I every time I would make smoothies I didn’t want it to go for a minute and if I pulled it up off the base like the instructions said, I would get liquid everywhere. But then sometimes it didn’t leak. Then on top of that, if I left it on the base for the entire minute so I wouldn’t have a leak, then my smoothies would be warm, and all of my ingredients where either from the fridge or the freezer. Any suggestions as to what I am doing wrong. I resorted to using my old 600 watt Nutribullet, but i want the Rx to work so desperately because I am past the time to take it back and get the 900 watt and because I like the Rx has a larger capacity cup. Please help me out thanks

    • I usually pull mine off the base early. I don’t have leak issues, but people who do often report that using the blade tool to tighten the blade helps. Also, be sure that you are not going over the fill line. You can also try using the soup pitcher instead, which makes it work more like a regular blender. I do that quite a bit for smoothies. I also often make my smoothies with frozen ingredients, which keeps things nice and cold.

    Can you explain how to separate the soup lid so it can be thoroughly cleaned? I have tried to pull the clear plastic vent lid off the rubber lid and cannot do it. It concerns me that I cannot properly clean this lid.

    • Somehow I missed your comment until now! Sorry to reply so late. The plastic piece on the lid should easily come off. It is removable on mine. Are you still having problems with it?
