SIDE NOTE – If you have a question about a specific Ninja blender model then visit our HUGE guide to finding the best Ninja blender which is continually updated. In that guide we review every single Ninja blender on the market. Please leave specific blender model questions in the comment section of that post.

The list of Ninja questions is getting long so I added a Table of Contents below. Click on a specific question to be taken to it or continue scrolling down to read through all the questions.

How does Ninja compare to Nutribullet ?

Both Ninja and Nutribullet make similar looking personal blenders which are commonly referred to as “Bullet” blenders because of their shape.

In general, both are good but we have a preference for Nutribullet blenders. Visit our detailed Ninja vs Nutribullet comparison for more specifics.

Who sells Ninja Blenders ?

Ninja sells some of their models directly through their own website and through infomercials. The also sell through a lot of retailers. In fact, it can be very confusing when comparing Ninja blender models because Ninja will make specific model #’s for each big retailer.

Typically Ninja blenders are exactly the same among the different retailers but the model #’s are different because they make a slight change in accessories so that each retailer is the exclusive seller of that exact model.

Typically we prefer buying through Amazon because the price is competitive and Amazon now directly sells many of the bestselling Ninja blender models (Meaning that Amazon cut a deal with Ninja to sell directly). Also, when buying on Amazon you can get inexpensive extended warranties for appliances.

Where to Buy Ninja Blenders ?

As mentioned in the question above, Ninja blenders are widely available but Amazon has the largest selection of models. If you are trying to research a specific Ninja model # that you saw at a retailer then check out our Ninja blender comparison guide which lists every model and explains the differences.

Which Ninja Blender is Best ?

We have a huge Best Ninja Blender buyer guide that is continually updated and reviews every Ninja blender to help you decide on which Ninja blender to buy (At the top of that article is a table listing our top choices).

If you have questions that aren’t answered in that post to feel free to leave a comment and we will answer them.

Which Ninja Blender is Best for Juicing ?

Ninja blenders are NOT juicers. Juicing means you remove all pulp and leave only juice. You can sort of use a blender as a juicer by pureeing the ingredients and then pouring that through a fine mesh sieve to get the juice.

Keep in mind that a high horsepower blender will typically create a finer blend for straining out the juice compared to a low cost blender. It also really depends on the ingredients you blend to determine how finely it blends.

Consumers can often get confused about Ninja juicers because Ninja markets their products as creating “complete juicing” which simply means it is the entire fruit or vegetable with the pulp (which is not juicing).

See related articles: juicer blender combo review and Juicing vs Blending comparison.

Which Ninja Blender is Best for Smoothies ?

All of the Ninja models with the total extraction blade(which work with the Nutri Ninja personal size cups) work well for smoothies. If you want a full-size blender then two good Ninja blender for smoothies are BL660 (Low price) & BL642 (Mid Price)

What is the Newest Ninja blender ?

Ninja has so many different models that they introduce and discontinue and the models will differ among the retailers that sell them. We continually update our Ninja comparison guide with the new models.

Can I use Hot Liquids in Ninja Blenders ?

We wouldn’t suggest using hot liquid in Ninja blenders. Definitely don’t use them in the Nutri Ninja cups because they can build up pressure from the heat and cause harm when opened.

Ninja does say you can use some warm liquids in some of the large blender pitcher but read the instructions for the specific model you choose. Ninja won’t turn cold liquids into hot just from blending like Vitamix blenders do.

What is Nutri Ninja ?

Nutri Ninja is just a marketing term for their personal blender blade and cups.

Is a Ninja blender the same as a Food Processor ?

Yes and No. Ninja makes blenders but they have added food processor components to those blenders. Ninja has a lot of models and different blades and pitchers and some of their blenders will work as food processors.

For blending/pureeing ingredients, Ninja has the “total crushing blade” and “Nutri Ninja extraction blade”. You can chop or dice with those blades by pulsing the blender but they can be limited in their food processing capabilities.

For food processing, you can get one of the Ninja blender models that comes with separate food processing blades and bowls for added food prep capability. The food processing bowls and containers will have a wide bottom with special blades that work better for food processing. Whereas a blending blade is designed to pull the ingredients down into a vortex for pureeing.

Are Ninja Blenders Dishwasher Safe ?

Yes, you can put the containers into the dishwasher but we prefer to rinse with some warm soapy water right after using for longevity rather than put them in the dishwasher.

How to Clean a Ninja Blender ?

As mentioned above, Ninja blender parts are dishwasher safe but we prefer to rinse with warm soapy water. You can blend or pulse with the soapy water in it for quick cleaning.

Why is Ninja Blender Power Light Blinking ?

The Ninja power light will blink if you don’t have the pitcher and lid on securely. Ninja has this as a programmed safety feature. Also, if you are using Ninja Auto IQ or pre-set programs then make sure you are using the proper container for that program.

What is Ninja warranty on their blenders ?

Ninja typically has 1 year warranty on all their blenders. We suggest getting an inexpensive extended appliance warranty like this one since blenders overall have more potential for breaking versus other kitchen appliances. You can read warranty details on their website. Read more about our thoughts on Ninja blender warranties in our Ninja FAQ section.

Can Ninja cups go in the freezer ?

Yes the Ninja jars and lids are freezer-safe.

Can Ninja Blender make nut butter ?

Yes. Ninja blenders can make nut butters. The Ninja Mega blender is a good choice for making nut butters. The only downside with Ninja blenders is no tampers which are really useful for certain tasks like making nut butter.

If you plan on making a lot of nut butters then Vitamix is worth considering because they excel at that task. Also, the brand new Ninja Chef might be worth considering because it has a tamper and even a nut butter program setting.

Can Ninja blender crush ice ?

It depends on which model you have. Full size models can crush ice especially the models that come with the total crushing blade. The single serve models with Nutri Ninja cups are not designed for crushing ice but they can do so with liquid added.

How to Open Ninja Blender ?

Some Ninja models have a locking lid to prevent the sharp Ninja total crushing blade from falling out when you pour. Just follow the instructions in your manual. The locking lids just have a push button and you line up the arrows to lock in the lid.

How to Sharpen Ninja blender blades ?

We would generally suggest not sharpening your blender blades as you can potentially void the warranty or cause injury. Typically if a blade is not serrated then you can use a standard knife sharpening rod like this one.

Do Ninja blenders leak?

Typically no but if you overfill the pitcher or jar past the recommended levels then you risk the chance of leaking or spilling.

Do Ninja blenders have an exact fill line ?

Yes, there are line markings on the 40oz bowl & 48oz pitcher to indicate the amount of ingredients that can be placed in the bowl or cups. Also there is a max fill line on the single serve cups.

Are Ninja blenders noisy ?

Yes, Ninja blenders can be noisy but they are typical for the market. There are certain blenders that are created for generating less noise but Ninja does not make any specific models for that need.

If noise is a serious concern then check out our quiet blender review for specific models.

Can I grind nuts, seeds, or coffee beans with Ninja blenders ?

Yes. Ideally the single serve Nutri Ninja cups are great for grinding but the full-size pitchers work fine too.

Can I make flour with Ninja blenders ?


Are Ninja blender attachments interchangeable ?

NO. Many of the attachments are not interchangeable. Make sure you understand the exact accessories you are getting with the model that you choose. For example, the dough blade, cookie dough paddle, and slicer/shredder attachment will only work with 40-oz processor bowl.

This is one of the biggest issues with Ninja blenders is the lack of uniform accessories across blender models especially since they frequently introduce and eliminate blender models from the market. You can reference their support section of their website if you are trying to get a specific accessory.

I bought a Ninja Power kitchen 1100 a few years ago but did not take it out of the box until about 2 years ago. it has the tall 72 oz and 48 oz pitchers. the blender never worked. so I bought the Ninja 1000 BL610 model. can I use the pitcher from the first blender with the Ninja 1000?

    Anna Powell

    Hi, I would assume no as Ninja does continually change their design which makes it difficult for past models accessories to be compatible with newer models. I am not completely sure though so I would ask Ninja about that. Support # is 866-826-6941


Hi! I have a ninja professional blender 1500 for past three years! Since yesterday i am only able to use my single serve option as the other buttons are not working and there is a constant green light on the single serve option! Please help!

    Anna Powell

    Hi, I am not sure. Try unplugging and replugging in to potentially reset it. It sounds like the power light is working and typically people only have issues with the red light blinking(meaning the container isn’t on the base correctly or the lid isn’t clicked down securely) Did something happen to your pitcher that caused the blender base to not recognize it suddenly ? Try contacting Ninja 866-826-6941 for your issue as I don’t have an answer.

Joy Somero

My single serve cup leaks some when on the blender base. Is the gasket supposed to be replaced when this happens? I am NOT overfilling it and it sprays out a bit and leaks down the sides when I set it back straight up.

    Anna Powell

    Hi Joy, Does it leak at the edges of the cup or underneath blade where the blade spins ? If it leaks at the edges of the cup and the gasket isn’t broken then the leaks are either caused by not tightening the cup enough or overfilling. If it leaks through the bottom of the blade then replace it as it is defective.

Deborah Hewitt

I just need the small black piece that goes on top where I attach blade. Can I purchase just taht piece?

    Anna Powell

    Which model are you talking about ? Not clear which part you are speaking of.

Gary Oda

Hi Anna,
I just bought an Ninja Auto-iQ blender, model# BL490. I used the Smooth Boost w/Blend to make a smoothie. Then I tried to use the Smooth Boost w/Extract to make a juice but it didn’t work. All I got was the Extract indicator light blinks and the timer shows two dashes. All of the other buttons work except for this one.

    Anna Powell

    Hi Gary, Each preprogram is designed specifically for the jar attached to the base. Certain programs will only work when certain jars are attached. If the program light does not illuminate when the jar is attached, that program will not run and you will get an “- – ” message on the display.


Hi, is there an attachment for the Nutri Ninja with Auto-IQ that can be bought for blending hot liquids?

    Anna Powell

    The answer is yes and no. None of the standard “Bullet” upside cups where you screw the cup on the blade are for hot liquids simply because the pressure builds up inside the cups from the heat and can cause safety issues. You can only do hot liquids in jars that have a venting lid for the heat/pressure to escape. Technically the only jar I know of for Nutri Ninja Auto IQ with a removable lid is the 48oz multi serve jar. You could technically let heat out manually while blending to do hot liquids. Here is the jar or call Ninja customer support directly to confirm. 866-826-6941


My Ninja BL680REF started to smell like burning rubber and making a strange sound so I turned it off and turned it around to look at the back. My hubby uses it mostly and he had not been wiping it off properly and/or tightening the lid because their was dried product on the back. I haven’t turned it on since. what can I do to clean it from the inside?

    Anna Powell

    It is really hard to clean from the inside. You can risk taking it apart but there are no guarantees it would work properly. I wish I could be more helpful with your problem.


I have a Ninja professional with 1000 watts. I put the blade into the cup, put it on the base and pushed on it. Nothing happened so picked up the cup. It came off the blade dumping the contents all in the base around the blade. Obviously I didn’t have it screwed on correctly. How can I clean it? I tried qui tips, a toothbrush and a little water. Have I ruined my blender? 😳

    Anna Powell

    Hello Carole, it is hard to say as it really depends on the specific spill. I would try a hairdryer. Sorry I couldn’t be more helpful.

Debi Yocca

I love my Ninja 1000 Watt Professional blender with single serve cups but a small, black, rubber piece came off and now every time I use it on single serve fluid leaks out. The piece that came out looks like a “plug” of some sort. I can’t find my manual to see where it came from. Any assistance you can offer would be greatly appreciated!!! My morning Bulletproof coffee is a mess!!!
Thank you!!!

    Anna Powell

    Hi Debi, I am having a hard time picturing what the piece looks like. For nutri ninja blade there is a little rubber gasket on top that surrounds the blade but it would have to be ripped open in order to come off. Otherwise it must be under the blade. Does it leak when you just fill up the cup and screw on the blade without running the blender ? I assume you probably have the popular BL660 model so here is a link to their manual to download. Otherwise I would contact Ninja support and see if they have advice. Also, you can just buy a new Nutri Ninja blade from Ninja.


My ninja 1000 goes on, but the blade hardly spins.

    Anna Powell

    Hi Joelle, Does the blade spin when you try to turn it manually by hand ? Trying to understand if it is a problem with the blender motor or the actual blade/container. If you can’t get it working I would call Ninja support 866-826-6941


My ninja is stuck on single serve only. When I put large pitcher on base, it wont work.

    Anna Powell

    Hi Scott, try unplugging it and see it if resets. Otherwise call Ninja Support 866-826-6941


I have the Nutri Ninja professional 1500 watt system which consists of the blender, food processor and smoothie maker. I put the blade in the dish washer (bad move) and it fell down and the plastic casement on the blade melted. I have tried to buy the correct replacement but don’t know which to order. Nowhere on the box does it indicate the model number (B…). Received one blade, approx 4″ diameter, but it was too large to fit the base. Do you know specific replacement blade I should order?

    Anna Powell

    Hi Nancy, Check out Ninja available accessories for sale for the Ninja Pro 1500 kitchen system that Ninja sells direct. Here is a link (just click “View More” on the page to see all the accessories). I am not sure which blade you are referring to? I am assuming it is the total crushing blade.

    For finding a model # typically on all Ninja blenders it will be on the bottom of the blender base listed on a “Rating Label” sticker or on the bottom of the body. If you still can’t figure it out, you can try calling Ninja 866-826-6941

Misty Hughes

We got our Ninja Chef Blender last December 2017 and use it every day. Recently it started making a high pitched squeaking noise. What should I do to fix this?

Thank you.

    Anna Powell

    Hi Misty, I would definitely contact Ninja about that. It sounds like something you should make a warranty claim about. Ninja support # is 866-826-6941

Dolly Konz

Hi, Anna. I put my Ninja 32 oz cup on the base thinking the kid was screwed on but it wasn’t! Oops!!!! My smoothie ingredients spilled all over it and the rest of my kitchen. I desperately wiped it down and hosed it off with my sink sprayed. After drying it off, I was able to blend my new smoothie for about 40 seconds. Then it stopped and the red light now blinks every time I try it again. I cleaned it more with a dry toothbrush. It clicks into place but still blinks.
I am trying to give it a rest in hopes that it will fully dry and revive.
Do you have any advice? Thank you!

    Anna Powell

    Hello Dolly, sorry for delayed reply(I was on vacation). Which Ninja blender model do you have ? Typically liquids inside the motor will he hard to fix. I know putting submerging a cellphone in dry rice will really help absorb any remaining moisture and could help with a blender . Typically with a blender I turn it upside down and use a hairdryer right after any spill.
