Ninja QX401 Stealth IQ Kitchen System

Powerful enough to make nut butters, pestos, crush ice. Easy to clean. Durable, versatile. Love it!

So happy with this machine 10 out of 10 all around...

highly recommend this product i use it many times have not found one product that i can not use in it

Loved this Ninja IQ kitchen system. Just need to push the button and it detects how much it needs to blend. Our smoothie bowls came out the perfect texture and it was so easy to clean.

This is a good blender/ food processor overall, it's not silent, however it is quieter than other blenders. When purchasing a food processor we chose this one as I thought I could use it while the kids were sleeping and not wake them up. This is mostly true. If you have light sleepers, and your kitchen is close to their bedrooms then this might be a problem for you. To get a gauge for how loud this is I'll say that you can have a conversation while the blender is going full ball and only have to slightly raise your voice to be able to hear the other person well. You definitely don't need to shout to be heard. The main thing I have been annoyed with is there's no pause feature in the settings, you start a program for 60 seconds and if you notice that the food is just sticking to the sides, you have to stop the program entirely, wipe the sides and start a new program of 60 seconds again. My other complaint is that when working with the blender it doesn't work well to only have a small amount of food in it, it works much better when there's 50mm or more in the blender attachment. It can be alright with it less full if the contents is watery. The blades are razor sharp, however I have noticed there's little dents forming on the blades of the food processor after the hardest thing we blended was nuts and seeds. So far I haven't noticed this effecting the performance of the blades though. I'll try see if I can get Ninja to look further into this and possibly replace under warranty and update this depending on their response. build quality is good, I would expect these parts to last longer than the warranty period, all the attachments are made from a sturdy, clear plastic. We haven't tried anything in the dishwasher with fears that it may make the parts not last so long. I cannot comment on the longevity of the product as I've only had it one month.

Love the Ninja Stealth IQ kitchen system. It makes for easy cooking by having 3 devices in one. The jug blender easily chops and minces to make amazing salsas. The single service blender with the blend sense mode takes all the effort out of making a smoothie and you end up with the creamiest, smoothest smoothie I’ve ever had. The shield adds a great barrier making it the quietest blender too. The food processor is great for quickly slicing or shedding vegetables and making dough. It shreds in a matter of seconds. However it doesn’t shred completely and leaves behind some large chunks of carrot but overall not bad. This has now become a staple appliance in my household. Love it!

I love this Blender/Processor, it is so easy to use, fairly quiet and something I have needed and wanted for a while! I did use the quiet cover for the blender and didn’t find it made a difference, however this did not bother me at all. I will be buying one of these for my sister in the future as well.

The Ninja Stealth IQ Kitchen System is excellent for everyday use. It handles large chops and blends tomatoes smoothly for homemade sauces, makes iced coffees and drinks with ease, and the grating and slicing functions work very well. It’s also perfect for baby purées. The silent dome significantly reduces noise, making early-morning smoothies possible without waking the house. Easy to assemble and clean, it’s a very practical and versatile kitchen appliance.

Having owned various Shark Ninja products over the years, I always know they try to add some kind of different technology. This time it was the stealth technology. I was sceptical that it could reduce sound by 40% but was pleasantly surprised when trying it out. It will be a game changer when making smoothies first thing in the morning when the family is still sleeping. The system comes with most of what you want, crushing and chopping blades, food processor bowl, a large jug and 3x single serve cups. It is dishwasher safe, perfect for quick cleanups and has blendsense to automatically detect what speed is required. The only thing that is missing is a juicer attachment. Overall it is a great blender and definitely cheaper than alternatives like Kenwood and Breville.

I can’t express enough how much we love this machine, my kids are absolutely into it! The smoothie adapter has been a huge hit in our home. I’ve been making delicious salsa with the food processor and blending up tasty sauces. I'm really impressed with the suction cup bottom and how easy it is to use. This machine has everything you could want, it’s simple, quick, and looks fantastic. Im not the greatest cook in the world but this makes it fun and easy to try new recipes. The only downside is you need a lot of space to store it all. But if that’s not issue this is great!

This Ninja Blender + Processor Set has been useful in so many ways! First of all with the blenders, it comes with a single serve cup as well as a jug so you can use them according to the serving sizes you’re planning to have. The blenders have been true its name and is really quiet compared to other blenders I have had. The processor jug can be more noisier but it’s not something I would complain about. The disc attachment for the processor jug is reversible, with both a slicer side and a shredder side. I tried 3 vegetables; beetroots, red cabbage and carrots. Beetroots came out beautifully sliced with the slicer. Red cabbage was a bit confusing cause I used the shredder side thinking it would grate it, but it turned out more minced than shredded. Carrots came out grated using the shredder so I was pleased with that but I think that using a high speed is better than using the slow speed on manual mode. Overall, it’s a versatile set from Ninja and I’m very pleased with it!

I was impressed with the intelligent technology which automatically senses the ingredients and adjusts the settings to deliver consistent results. It’s incredibly easy to use with a one touch smart mode that does the thinking for you. The automatic sensing saves valuable time by eliminating guesswork and producing faster, consistent and reliable results. The system is so versatile and handles blending smoothies, chopping vegetables, crushing frozen fruit and making dough. The attachments are simple to use and proved to be strong and reliable while chopping tough vegetables and kneading pizza dough. I also appreciate the thoughtful design, the all in 1 machine makes options endless options and the individual cups allows the family to enjoy personalised drinks. I was pleasantly surprised by how quiet and peaceful it is to use. The dome attachment is genius making it ideal to use early mornings or late evening. It’s transformed my meal prep making it quick, easy, enjoyable. I love it!

I’ve been using the Ninja Stealth IQ Kitchen System for a week and it has exceeded my expectations. The blending power is excellent — smoothies with frozen fruit and ice come out consistently smooth, and the processor attachment handles chopping and slicing with ease. The BlendSense Technology is very convenient, automatically adjusting speed and time, which takes the guesswork out of blending. What really stands out is how quiet this blender is compared to other high-powered blenders. The noise-dampening design makes it comfortable to use even early in the morning. The controls are intuitive, assembly is easy, and switching between attachments is quick. Cleaning is simple, with most parts rinsing clean or being dishwasher safe. Overall, it’s a powerful, quiet, and versatile kitchen system that makes daily meal prep faster and more enjoyable.

I was stoked to try the Ninja Stealth IQ Kitchen System - Power Blender + Processor Pro. I don’t love blenders because they are always so loud… not this one, I can almost blend at any time of the day! I love the different functionalities as well that make it the perfect kitchen companion! I’m looking forward to trying it to make dough :)

After using the Ninja Stealth IQ Kitchen System for couple of weeks, I was extremely impressed! With three different attachments such as food processor, blender and single serve cup, it helps immensely in the kitchen, especially when you are short on time. What I found really impressive was when I was blending my smoothies, it would sense what was frozen or fresh and would adjust time and speed so all ingredients was perfectly blended. The noise is quieter compared to other blenders and I quite enjoyed the Stealth Shield which absorbed a lot of the sound. All the blades for each attachment are quite sharp (be careful when cleaning) but it ensures all ingredients are perfectly chopped. The food processor has different modes and speeds to ensure your ingredients are chopped to your desire or if you would like full control you could just push the manual button. The dough mode is also a handy feature for cakes. The Ninja has made meal preparation a whole lot easier!

ninja stealth iq kitchen system - power blender + processor is life saver for me from this product doing cooking is so much quicker and easier for me the blend scence tecnology is amazing i’m so much in love with this product and i definitely recommend this product to others

I’ve been really happy with this food processor so far. It’s definitely quieter than others I’ve used, and it blends incredibly smoothly. I also love that it comes with multiple smoothie jars, a processor bowl, and a large blender — super versatile for different kitchen tasks. One thing to be careful about: the blades are extremely sharp. I’ve accidentally cut myself while washing them, so handle them with care. Overall, it’s been a great addition to my kitchen and has made meal prep much easier.

Absolutely love the Ninja Blender and Processor Stealth IQ Kitchen System. The blender and processor combo is incredibly convenient, and it handled my test run -a mango shake - absolutely beautifully. All the different parts feel very durable, love the layered blades and I was surprised by how quietly it runs. My kid, who usually gets scared of loud blenders, didn’t even notice it was on! This system has definitely earned a permanent spot on my kitchen counter for daily smoothies and meal prep. My family cannot wait to try all the delicious recipes our previous blenders couldn’t handle.

My family and I absolutely love this versatile new addition to our home. Its ease of use even allows my 9 year old to carefully create her own smoothies. It’s easy, quiet, attractive looking. We love it!

I have been obsessed with this system since it arrived at my home. I have used it to make pasta sauce, curry sauce, milkshakes and other meals. I found it so easy to use, especially the blend sensor, which allows me to place one of the vessel's and press the sense blend button and I get perfect meals/drinks each time. The cover for the smoothie cup really cuts down the noise and my husband now uses it daily and I do not hear him anymore. I love that it is multiple vessels so I have been able to replace multiple equipment pieces with this one.

The Ninja Stealth IQ Kitchen System is honestly the best and most versatile piece of equipment I’ve ever had in my kitchen. I’ve already made blended soups, hummus, pasta sauce, grated cheese, and fresh mango–banana smoothies, and it crushed everything. I even processed nearly half a pumpkin’s worth of soup in one go, and it handled it easily. The power is amazing; smooth, consistent results every time. It’s also fast and saves a ton of prep time. The controls are simple, everything clicks together easily, and cleaning the jars and blades is quick. All the attachments feel solid and genuinely useful, not just extras you forget about. It works well for both big batches and small jobs. One thing that surprised me is how quiet it is for its size and power—more of a low hum than a roar. Overall, this thing has genuinely upgraded my whole kitchen routine.

Love this blender! It mixes everything silky smooth so quickly, and the Stealth cover is such a game changer, the noise level is so much lower than I expected. I can actually make smoothies in the morning without waking up the whole house. Super powerful, super quiet, and honestly just really easy to use and easy to clean.

The machine is quite low decibal so although you can obviously hear it running it isn't too loud. It's a decent size for cooking a good quantity of food. We fit 500g of mince and some veg in with loads of room to spare. Super easy to pull apart and clean and some parts can even go inthe dishwasher. Storage wise, even with all the pieces it fits into quite a small amount of space in the cupboard. Would definitely recommend to anyone looking for a blender and food processor.

This blender and processor combo is perfect for all needs, it has so many attachments suitable for all your tasks. From blending smoothies to mincing and shredding vegetables in the processor. The motor is very powerful and never skipped a beat and never sounded like it was ever struggling, whether that was slicing through frozen vegetables, ice and chunky vegetables. The settings programmed into it are very helpful. I thoroughly enjoyed being able to set the food processor to chop into 3 different sizes, it has a smart sense to spin and pause in the right timings to achieve this. All pieces are easy to assemble and disassemble for easy cleaning in the dishwasher or hand washing in the sink.

I received this product a week ago, I tried almost everything with the processor, blender. Best thing about this the Auto Sense system. It sense automatically the speed and time. I tried dough making it only took 1.5 minute to make a dough . On my other dough maker, it was taking 7-8 minutes. Such a time saver. And best thing there is no chunks left when it comes to blend pury for pasta etc. Pulse system works efficiently. I am really very happy that Ninja become a part of my kitchen. Also, I have 3 years old toddler at home. Before, I skipped using blender while she is sleeping because of nice. Ninja comes with extra layer of pitcher fir blending to reduce noise. Now i can blend while she is sleeping. So happy.

This is the ultimate holy grail of a product!! Honestly!!! What an amazing, game changing blender and food processor. So insanely easy to use, easy to clean, and sooooo versatile.. this product will be in high use in my household!!! Literally you cannot go wrong, the product has a lot more intelligence than me when it comes to picking the right setting and determines how long it needs to blend and what setting to have it on. With 2 small kids this product will have your smoothie and juice game going strong!!!! Couldn’t be more excited about a blender that just does it all! I actually cannot fault this product, it is incredible!
