Shark Ion Flex – Cordless Vacuum Review (With Three Alternative of ionflex 2x)


There is more to a vacuum cleaner than it meets the eye. Recently, more and more people started investing in a cordless vacuum, for its obvious and less obvious benefits.

And since I needed a replacement for my old vacuum, I went cordless too!

Did my usual research, minding all vital features and characteristics of a quality cordless vacuum.

The pursuit ended when I stumbled upon the Shark Ion Flex; it looked futuristic, elegant, smooth… Looks aside, it also cleans efficiently and rapidly, which is why we decided to share our comments on this cordless shark vacuum; we hope you’ll enjoy it.

Why A Cordless Vacuum?

The most obvious benefit of having a cordless vacuum is the fact that it is, well, cordless. Cordless vacuums allow more convenient and rapid cleaning because you aren’t dragging a cord alongside you.

This is particularly annoying when you are cleaning the stairs of upholstery.

Cordless vacuums are also generally lighter than the corded vacuums. Furthermore, it is much safer to clean your home with a cordless vacuum because you don’t have to worry about people stumble over the vacuum’s cord.

However, you will have to charge the battery. Many vacuum cleaner manufacturers struggle with making a quality battery system, which is why you need to pay close attention to it if you decide to buy.

On the other hand, it is convenient that you don’t have to worry about electrical sockets.

However, should you buy it; should you buy a cordless vacuum cleaner? Well, that depends on your needs. If you vacuum cluttered spaces, tight areas, upholstery or stairs, then yes, you should probably opt for the cordless vacuum.

Of course, you need to make sure that you buy the right one. While cordless vacuums have their benefits, they have flaws, and you’ll have to recognize those flaws if you want to feel satisfied with your new purchase.

Presenting the Shark ionflex

Shark IONflex vacuum CleanerThe name ionflex implies two things:

  1. The shark ion flex is powered by the lithium-ion rechargeable battery
  2. The shark ion flex features Shark’s MultiFLEX technology that allows you to clean those hard to get spots without hassle and inconvenience

But shark ionflex is much more than that. It also has a DuoClean technology, one that is found in most Shark Rotators and Navigators.

Aside from excellent on-carpet performance, this vacuum was also designed to allow more straightforward above-floor cleaning.

Thanks to its design, it rapidly transforms into a handheld vacuum cleaner, making stair and car cleaning much more convenient.

It also packs some additional accessories; crevice tool for close-to-wall cleaning, an extensive tool for cleaning upholstery, hypoallergenic dust brush and of course, a battery with charger.

Most importantly, Shark ionflex 2x (Check the video to see how it performs) is soo convenient and flexible, allowing you to clean your home rapidly and free of frustration.


  • Value for money.
  • Flexible and lightweight.
  • Excellent for vacuuming pet hair.
  • Features DuoClean technology.
  • MultiFlex design.


  • Can be hard to navigate (especially for those that are new to Shark vacuums).
  • The charger can charge only one battery at a time.
  • Relatively low dustbin capacity.


Shark ion flex 2X Review on the basis of  Design, Durability, Efficiency, Usability

We will approach this vacuum from the inside out. First, we’ll explain its design, the way it moves and feels when you use it. Then we’ll proceed to the way it works and answers questions regarding durability, efficiency, usability, and so forth.

On Design

Shark IONFlex Design

The Shark IONflex DuoClean vacuum is 13.4 x 10.4 x 45.9 inches large and weighs 8.7 lbs (with all attachments and dustbin). The product has a 0.3-quart dustbin and arrives with two batteries (hence the 2X) and a charger.

This vacuum merges two technologies, SmartFlex and DuoClean, and delivers a cord-free vacuuming, simple safekeeping and inexpensive maintenance.

Thanks to the combination of these two technologies, this vacuum can function in three modes:

  • Upright Modethis model implies the use of added-in soft brush roll that not only makes vacuuming more efficient but also allows the vacuum to transition from surface to surface smoothly.
  • Reach Mode – SmartFlex technology delivers a very flexible wand that can bend and make it easier for you to vacuum under furniture.
  • Above-Floor Cleaning Mode – lastly, this vacuum can be used in an above-floor mode to clean the corners, walls, and shelves with convenience and comfort.

On Cleaning Performances

Shark IONFlex 2x Features for Cleaning

The Shark IONflex is potent and durable. It derives its power from the included Lithium-Ion battery. You receive two batteries, both of which are removable and rechargeable.

The fact that you get two batteries also means that you’ll have one fully charged battery at your disposal. Should you run out of power during your cleaning crusade, you can swap them with ease and without any hassle.

When it comes to cleaning, this vacuum uses the already mentioned DuoClean technology. What this means is that the vacuum uses two brushes while cleaning:

  • An extensive bristle brush for cleaning carpets and extracting stubborn debris, including pet hair
  • A soft brush roll that is in direct contact with the floor. The vacuum uses this brush not only to vacuum floors and large particles but also to collect give it a fresh look and a sense of cleanliness.

Of course, cleaning performance is also significantly affected by the use of attachments. They are all quality made and serve a unique purpose, and you should use them appropriately.

For instance, the crevice tool made it so much to clean tight spots, corners, and wall.

We also commend the integrated LED lights, which make it easier to vacuum in dark spots and areas. They also affect the vacuum’s appeal, making it look very stylish and futuristic.

On Power Supply And Vacuuming Function

Shark IONFlex Power Supply and Battery

As you already know, Shark IonFlex is a cordless vacuum. It uses the battery as its primary and only source of power.

You also receive a compatible Shark charge, which you use to charge the included batteries. The battery’s performance is significantly affected by the mode you use. These mods are:

Max Function: this is the most potent option during which the vacuums uses its maximum power, resulting in more effective cleaning. However, it will drain the battery in roughly 11 minutes. If you use two batteries, 22-

Extended Runtime: in this mode, the vacuum will use less power but also clean less efficiently. In this mode, the battery usually lasts 20 minutes.

Now keep in mind that the runtime is much affected by the modes we already mentioned (Upright, Reach and Above-Floor Cleaning.) For example, if you use this vacuum as a handheld vacuum in combination with Extended Runtime, it can vacuum 20 minutes.

However, if you use it in an Upright Mode in conjunction with Extended Runtime function, it can vacuum for 15 minutes.

You can switch between these power functions via the at-fingertip control board (see the video) which is built in the vacuum’s handle. On the handle, you’ll also find the switch for floor or carpet cleaning.

Other Notable Features

Shark IONFlex reviewAside from being cordless, Shark ionflex is also free-standing. Thanks to the SmartFlex technology, the vacuum can stand on its own without the support of other objects.

Now all these benefits (cordless, rapid battery exchange, fast charging, and SmarFlex technology) are implemented to take vacuuming on another level.

This vacuum feels like no others because of its smooth and easy-to-navigate design.

It crosses from the surface to the surface without any issues, and more importantly, you can adapt to floors and carpets with a single push of a button.

While it is suitable for floors and carpets, we have to say that it performs amazingly on carpets; it is suitable for cleaning floors but fantastic for cleaning carpets.

It is also an excellent option for pet owners, thanks to DuoClean technology.

Add in the fact that this vacuum is light and flexible and you’ll get a more uncomplicated and hassle-free cleaning of carpets, pet cages, and pillows. Plus you’ll be able to clean your vehicle in no time!

For more info regarding the difference between these two vacuums, refer to the Shark 201 vs 251 articles.

Shark Rocket HV382 almost Similar to Ionflex

Shark Rocket HV382 reviewThe Shark Rocket HV382 is similar to IONflex. It features the same DuoClean technology, it has LED lights and is excellent for pet owners.

It is also very lightweight and convenient to use.

However, it doesn’t feature SmarFlex technology and is less flexible in that regard. It is also corded, so it doesn’t bring with it all the benefits of cordless vacuums.

Dyson V7 – Ionflex Alternative but Expensive

It does transform rapidly into a hand vacuum and is very comfortable to use.

While it does perform better on floors, it isn’t an ideal pick for pet owners. It does arrive with cool attachments, but so does the IONflex.
