What Interesting About The Nutribullet Rx?

First of all, the Nutribullet RX has a heating function for soups and sauces. You load the “souperblast” pitcher with your ingredients, screw it onto the base, and press the “g” button until it turns red. The 7-minute cycle will begin, blending and heating the soup, before automatically turning off.

It doesn’t have a heating mechanism per se, the heat comes from the speed and duration of the spinning blades.

Note: you never put hot liquids into the RX, you start with cool or lukewarm liquids/ingredients and the blender will heat it for you. I add that because I personally would probably make the silly mistake of thinking that if the RX is safe to heat things, it’s safe to blend already-hot ingredients.

Second interesting factor to note, the RX has a super-high wattage of 1700. This is pretty colossal compared to other Nutribullets, such as the Pro 900 which has, well, 900 watts of power. At 1700 watts, you’d hope for the smoothest smoothie ever, with not a chunk in sight. We’ll assess this factor further below.

Lastly, the RX comes with a little tool to tighten or loosen the blades. Sure, this isn’t riveting information, but it does seem important considering the fact that hot soup is going to be coming out of the machine. For this reason, the tightening tool is handy to ensure the blade assembly is tightly screwed onto the Souperblast pitcher to prevent leakage.

It also helps for when the blade assembly expands due to the heat, and becomes too hard to unscrew by hand.

It’s interesting and useful to note that many reviewers have urged existing and future RX owners to always use the blade tightening/loosening tool when removing the blade housing from the vessel. They say that this ensures that the rubber gasket stays put, and doesn’t slip out, like many customers have experienced.

What do other customers and reviews say?

As of now, the reviews are very varied. The 5-star section has 62% of the votes, and the 1-star section has 14%. This tells us that yes, there are some stellar features to behold, but there are also some pitfalls to be aware of before handing the cash over. Let’s see what has thrilled and disappointed customers.

Positive

Easy to use: many customers who left happy reviews noted how easy the RX is to use. They like the one-touch button, hands-off blending, and easy clean up.

Powerful: the powerful, 1700-watt motor is a popular feature in the positive comment sections. Customers mention the smoothness of their smoothies, with no chunks or gritty texture, and they attribute this to the powerful motor.

Easy to clean: thrilled customers rave about how easy the RX is to clean. Either rinse it out and leave to dry, or pop into the dishwasher for a more thorough clean.

Negative

No pulse feature: some people have found the lack of a pulse feature disappointing. This isn’t a biggie, just a matter of preference.

Loud: the loudness of the RX has come under fire in negative reviews, but I think it’s just something you have to accept when using a super powerful blender. You could buy a blender cover to muffle the sound.

Leaks: quite a few unhappy customers have found that the RX leaks from the bottom, through the blade housing and into the base. Others have found that a greasy, dark substance leaks from the blade housing into the cup, contaminating the smoothie/soup.

Gasket ring comes loose: this is by far the most common complaint in the negative review sections. It’s quite a problem for many people, as they find the rubber gasket pops out of the blade housing, and even gets stuck or chopped up as the blender blends.

Others have stated that this can be completely avoided if you use the blade tightener tool each time you secure and remove the blade housing to the cups or pitcher. This is a common complaint across the board of Nutribullet models. Some suggest to keep the blade out of the dishwasher as the heat can cause the gasket to slip.

How Does The Nutribullet Rx Measure Up To The Vitamix in Terms Of Absorbing Nutrients?

It’s tough to say. The RX does have a higher wattage than all Vitamix blenders, at 1700 watts. We could assume that this extra power means that the foods are broken down to a smaller level, thus increasing nutrient absorption in the body. However, different foods require different levels of breakdown to release the most nutrients, so it’s difficult to make a good comparison between blenders in terms of nutrient absorption.

The short answer would be: they both blend foods very thoroughly, and the difference between nutrient absorption is most likely pretty minimal, if any.

Also note: when it comes to hot soups made with the Nutribullet RX, some nutrients may be lost. Enzymes which are heated to a certain point are destroyed. (This is why masticating juicers are more popular than centrifugal juicers when it comes to nutrients, as they don’t heat the produce…but that’s a totally different tangent).

How do you use it?

For the “Nutriblast” cycle, which is basically just the normal smoothie function of the RX, you simply place the filled and secured vessel onto the base and press the power button. The button will glow green and the blender will run for one minute before turning off.

The power button glows red during the “Souperblast” cycle, and runs for seven minutes, heating the ingredients as they blend.

Can I Put Ice In My Nutribullet Rx?

Yes, you can. You can use it like a regular blender for smoothies, shakes and frozen drinks. The 1700-watt motor smashes through ice really thoroughly. Many happy customers have left reviews raving about how their RX blends ice into a lovely slush.

How Does The Nutribullet Rx Heat And Cook Food?

The Nutribullet RX comes with a special pitcher and vented lid to make what Nutribullet marketing calls “souperblasts” (yes, you can just called it soup). Once you’ve loaded the pitcher with soup (or sauce) ingredients and screwed the vented lid on top, you screw it into the base. Press the “g” button on the Magic Bullet symbol at the bottom of the base until it turns red, this will turn on the heating function.

The RX will then begin a 7-minute cycle of blending which creates heat due to the rapid speed of the blades. There’s no actual heating mechanism in the base, the heat simply comes from the friction created from 7 minutes of 1700-watt blending. The soup reaches up to 150 degrees Fahrenheit.

How Loud is it?

It’s pretty loud, as you might expect from such a high-powered blender. There are blender covers on the market, designed to muffle super-loud blenders.

How do you clean it? Is it easy to clean?

Yup, it’s easy to clean and the cups and lids are dishwasher safe too. You just need to remember to rinse the blades immediately after use, to ensure smoothie and soup residue doesn’t dry and stick onto the blades. The blades shouldn’t be put into the dishwasher, as it can damage the gaskets. It’s best to give the blades a rinse and a quick scrub with a brush, then leave to dry.

What are the most common Problems With the Nutribullet Rx?

The rubber gasket can come out: by far, the most common complaint, as we learnt earlier. Many people have found that the rubber gasket pops out of the housing, and sometimes even finds it’s way into the blades. Others are adamant that this is completely avoidable if the blade remover is used to remove the blades.

Some reviewers have explained that by removing the blade with your hands, you are squeezing the housing from the outside, therefore creating a large enough gap for the gasket to slip out of. Whereas, when using the blade remover, the housing remains unchanged.

Leakages: leakages are also a reasonably common issue with the RX. Some people experience leakages from the blades and into the motor, while others find that an odd substance leaks from the blade housing and into the vessel itself.

The blade remover comes into play again here too, as reviewers have said if you use it to tighten the blades sufficiently, you won’t get leakages. Don’t take this as gospel though, as others have found the RX leaks even with the tightest blade application.

How Does It  Compare to other models?

Nutribullet Rx Vs 1200

  • Similar in construction, design, hands-free usage
  • The 1200 series doesn’t have a pitcher, it only has bullet-style cups
  • The 1200 series has 1200 watts, as opposed to the RX’s 1700 watts
  • The 1200 series doesn’t have a heating cycle which the RX does have
  • The 1200 series comes with an insulated stainless steel cup, which the RX doesn’t have

Bottom Line

Depends on whether or not you want or need the heating function, or just require a powerful blender for smoothies and drinks. If you need the heating, go for the RX.

Nutribullet Rx Vs Blendtec Total Classic Original Blender 

  • The Blendtec is a traditional blender with a base and a pitcher which loads from the top, and pours with a spout into a drinking vessel. It does not have bullet-style cups. The RX has a pitcher which is only for heating soups, and bullet-style cups which can double as portable drinking cups
  • The Blendtec has pre-programmed function buttons and “+/-” buttons for manually choosing speeds. The RX only has one button, the power button which is used for choosing the Nutriblast function or the Souperblast function
  • The Blendtec has a wattage of 1560, the RX has 1700 watts
  • The Blendtec does not have a heating function
  • The Blendtec is almost double the price of the RX

Bottom Line

If you need a solid blender with good power, lots of functions and manual speeds, and you don’t need heating functions or portable cups, then go for the Blendtec.

Nutribullet Rx Vs Breville Boss To Go Sport Blender 

  • The Breville and the RX are both bullet blenders with a base and bullet cups which can double as portable drinking cups
  • The Breville has a 1000-watt motor, the RX has 1700 watts
  • The Breville does not have a heating function
  • The Breville has a 23 oz cup and a 15 oz insulated cup. The RX cups are larger (30 and 45 oz), and are not insulated
  • The Breville has a pulse function, the RX does not
  • They are both similar in price

Bottom Line

Again, it depends on your needs and preferences.The Breville is simpler, has smaller cups, a smaller wattage, and doesn’t have a heating function.

Nutribullet Rx Vs Magic Bullet

  • The Magic Bullet is a lot cheaper than the RX
  • The Magic bullet has a wattage of 250 watts as opposed to the RX’s 1700 watts
  • The Magic Bullet has much smaller cups than the RX (the RX max capacity is 45 oz)
  • The Magic Bullet can grind dry ingredients such as spices, whereas the RX has to have liquid
  • The Magic Bullet doesn’t have a heating function

Bottom Line

The Magic Bullet is a good blender for making smaller batches of smoothies, shakes, dips, salsas, and grinding dry foods. But the RX has a lot more power, and larger vessels.

Nutribullet Rx Vs Ninja 1000 BL455

  • The Ninja 1000 is a bullet blender with a base and bullet cups, similar to the RX, but the Ninja doesn’t have a pitcher
  • The Ninja 1000 has smaller cups than the RX
  • The Ninja 1000 doesn’t have a heating function
  • The Ninja 1000 is much cheaper than the RX
  • The Ninja 1000 has 1000 watts, whereas the RX has 1700
  • The Ninja 1000 doesn’t have a manual on/off button, it’s totally hands-free, operated by twisting the vessel onto the base

Bottom Line

I think the Ninja 1000 is more solid than the RX, and has less risk for issues (i.e. leaking and gasket troubles). It depends on whether or not the heating function is what you’re after, or if you just need a powerful blender for smoothies and drinks.

Nutribullet Rx Vs Ninja Mega Kitchen System

  • The Ninja Mega Kitchen is a personal bullet blender, food processor, and pitcher blender all in one
  • The NMK has a 1500-watt motor, while the RX has 1700 watts
  • The NMK motor has 5 buttons: pulse, power, 1-dough, 2-blend, 3-crush, Nutri Ninja (for the bullet blender), the RX doesn’t have function buttons except the Souperblast button
  • The NMK doesn’t have a heating function
  • They are basically the same price, give or take

Bottom Line

If you need a personal blender, pitcher blender, and a food processor all with one base, then the Mega Kitchen System could be great for you. If you need a bullet blender for smoothies and the occasional soup, and you’ve already got a food processor, then the RX would be better.

Nutribullet Rx Vs Ninja Pro 900

  • The Pro 900 has 900 watts, the RX has 1700 watts
  • The Pro 900 doesn’t have a heating function, the RX does
  • The Pro 900 is cheaper than the RX, by around $80 give or take
  • The Pro 900 has 18, 24, and 32-oz cups, the RX has a 30-oz cup, a 45-oz cup, and a pitcher for soups

Bottom Line

If you need an affordable bullet blender for personal smoothies and shakes, then I’d go for the Pro 900. If you need multiple smoothie servings and hot soups, the RX is better. Also, the RX has more power, so if you tend to blend tough ingredients such as frozen fruit and kale, the RX might be a smarter choice.

Nutribullet Rx Vs Ninja Ultima

  • The Ninja Ultima has been discontinued, the RX is still with us
  • The Ultima is a bullet blender and pitcher blender in one, with different blades for each vessel (pro extractor blades for the bullet cups and the Total Crushing Blades for the pitcher)
  • The Ninja Ultima doesn’t have a heating function, the RX does
  • The Ninja Ultima has a 10-speed dial and a pulse switch, the RX only has one button (for the Souperblast), and uses an auto-cycle for blending
  • The Ninja Ultima has a 1500-watt motor, the RX has 1700 watts

Bottom Line

The Ultima is pretty good, but since it’s discontinued you’ll have to get a refurbished one, if at all. If you need a pitcher as well as bullet cups, take another look at the Ninja Mega Kitchen System.

Nutribullet Rx Vs Nutri Ninja Auto Iq

  • The NN Auto iQ has 1000 watts, the RX has 1700
  • The NN Auto iQ has 18, 24, and 32-oz cups, the RX has 30 and 45-oz cups
  • The NN Auto iQ doesn’t have a heating cycle, the RX does
  • The NN Auto iQ has auto-cycle buttons (blend and ultra blend), as well as a start button and a pulse button for more control. The RX has no buttons except the Souperblast button, otherwise it runs by a hands-free auto cycle
  • The NN Auto iQ blades are more angular than the RX blades
  • The NN Auto iQ is around $60 cheaper, give or take

Bottom Line

The Auto iQ is a great blender, with more options for the user to control the blending duration. It doesn’t have a heating function, but it’s powerful and pretty affordable. Both great options depending on your needs.

Nutribullet Rx Vs Nutribullet Balance

  • NB Balance has bluetooth capabilities and connects to the Balance app so you can calculate the nutritional info of your smoothie
  • The NB Balance has 1200 watts, the RX has 1700
  • The largest cup size with the NB Balance is 32 oz, the largest with the RX is 45 oz
  • The NB Balance doesn’t have a heating function, the RX does
  • The NB Balance is a little pricier depending on where and when you buy it, and if a sale is on

Bottom Line

If you want to track your macros and calories, then the Balance could be a good choice. It’s less powerful than the RX, but still very powerful with 1200 watts. However, you do pay more for the smart technology so it’s best to decide if you really need it, otherwise go for a simpler model like the Pro 900. If you need the heating function then of course, the RX is better.

Nutribullet Rx Vs Nutribullet Lean

  • The NB Lean has been designed to fit in with a weight loss program. It comes with portion-control plates, spoons, and the cups have markings to ensure the right ingredients are being portioned correctly. It comes with a 7-day weight loss plan
  • The largest cup capacity with the NB Lean is 32 oz, the largest with the RX is 45 oz
  • The NB Lean has a wattage of 1200, the RX has a wattage of 1700
  • The NB Lean doesn’t have a heating function, the RX does
  • The NB Lean is activated by a one-touch button which starts the 60-second auto blend, this is similar to the RX which has a one-touch button to activate the Nutriblast (smoothie) or the Souperblast (heating) functions which run on automatic timers
  • The NB Lean is slightly cheaper, depending on where and when you purchase it

Bottom Line

If you want all of the weight loss accessories such as the portioned plate, 7-day plan, access to the LEAN app, and portion-controlled cups, then the Lean is a good choice. Otherwise, you’re just getting a bunch of accessories you don’t really need. You may as well get the RX instead, as you’re getting more power, and the option of heating soups and sauces as well as making smoothies.

Nutribullet Rx Vs Nutribullet Prime

  • The NB Prime has 1000 watts, the RX has 1700 watts
  • The NB Prime comes with a 28-oz insulated, stainless steel vessel, the RX does not
  • The NB Prime does not have a heating function, the RX does

  • The NB Prime comes with flip-top lids for portable drinking, the RX doesn’t come with flip-top lids
  • The NB Prime comes with vessel grips, the RX does not
  • The NB Prime is slightly cheaper than the RX
  • The both run on auto-timed cycles with no buttons to press

Bottom Line

I like the accessories that come with the Prime, especially the flip-top lids and the stainless steel cup. If you just need a good blender for smoothies and shakes, I’d go for the Prime.

Nutribullet Rx Vs Nutribullet Select

  • The NB Select has 950 watts, the RX has 1700 watts
  • The NB Select has a control dial with 5 speeds, and “crush”, “pulse”, and “blend” functions, the RX does not have dials or manual functions, it runs on an auto-cycle
  • The NB Select does not have a heating function, the RX does
  • The NB Select comes with 10, 28 and 32 oz vessels, the RX comes with 30 and 45 oz vessels
  • The NB Select is slightly cheaper than the RX, depending on where and when you buy it

Bottom Line

The RX has more power, but the Select has the option of selecting the speed and function. If you prefer to have more control over your blending, and you don’t care about the heating function, then the Select might be better for you.

Nutribullet Rx Vs Vitamix 5300

  • The Vitamix 5300 is a comprehensive pitcher blender, whereas the RX is a bullet blender with cups as opposed to a large pitcher
  • The Vitamix 5300 has 1380 watts, the RX has 1700
  • The Vitamix 5300 can mix dough, the RX is not designed for this
  • The Vitamix 5300 can heat soups and sauces, just like the RX
  • The Vitamix 5300 is far pricier than the RX
  • The Vitamix 5300 has a 10-speed dial and a pulse button, the RX does not have manual functions, but runs on an auto cycle
  • The Vitamix 5300 has a capacity of 64 oz, the RX has a capacity of 45 oz

Bottom Line

If you’re in the market for a solid, long-lasting, pitcher blender to sit on your counter and be used for a wide range of tasks, then I would absolutely go for the Vitamix if your budget allows. It offers more versatility and control, and a much larger capacity.

Verdict: Is This Blender For You?

The Nutribullet RX is a great blender, if you take the leaking and the slipping gaskets out of consideration. The wattage is awesome, the heating function is handy, and the blending power for smoothies is fabulous. Personally, I wouldn’t use a blender for making soups, as I’m just a more traditional cook.

However, if you’re short of time and need a quick way to prepare hot, healthy soups then by all means, consider the RX. For something a little simpler, (i.e. for daily personal smoothies) and without the risk of gasket-slippage, something like the Nutribullet Pro 900 will serve you well.
