Features Of The Shark IONFlex Cordless Vacuum

Duo Clean

This is one of the exclusive innovations you get to enjoy just because you are using a Shark vacuum.

The powerful brush head on the Shark IONFlex Cordless has two brush rolls.

The one in front is a big soft brush that sort of trample on a pile of dirt while the stiff brush at the back sweeps it in.

The result of this is an exceptional deep clean on carpets, rugs, or hard floors.

Some other vacuums will require quite a number of passes to completely clean a pile of debris. That is not the case with the Duo Clean brush head on the Shark IONFlex. It offers  ”Triple Particle Cleaning” as Shark calls it.

This brush head design does not have a front wall. That way, it cannot snowplow a pile of debris which will spread it around. This makes it easy for the Shark IONFlex to clean up large debris, small particles, and even stuck-on dust.

While other vacuums will clean your hard floors of dirt and leave the dust behind, the Duo Clean will clean it all. The large and soft brush roll in front will wipe stuck-in dust of your floors leaving a polished surface behind.


Multi-Mode Usage

This advanced cordless vacuum can go from hard floors to carpets without you having to make many adjustments. The brush roll needed for both floor types are already active and on duty.

By default, the vacuum works in the upright mode so you can clean and move with ease from floor to floor.

It is also lightweight so you won’t be having any problems with steering it or even carry if need be.

There are furniture with floor space under them that needs to be cleaned too. Instead of moving the furniture around, you can just switch to the reach mode.

This brings us to the Multi-Flex feature. Between the handle and the brush head, you can adjust the wand such that it bends.

This action allows you to reach under furniture to clean properly. This feature can also let you reach into areas you wouldn’t if it could not bend.



Further, on the Multi-Flex technology, you can bend the Shark IONFlex all the way so it stands on its own. Quick question, how many other cordless vacuums can do that?

With this, you can park the vacuum anywhere you want. Just leave it where you stop if you want to take a quick break from vacuuming.

This also makes the Shark IONFlex easy to store as you will have only about half its true height to deal with.



This vacuum will go from a stick vacuum to a handheld in a jiffy. This transformation lets you do many other types of cleaning.

Now you can go from floors to the ceiling. You can dust your drapes, furniture, and even vents. All you have to do is install the right accessory.

With this transformer, you are not limited to indoor vacuuming anymore. You can take your vacuuming outside into your car. In the handheld mode, you can clean up the interior of your car and even wipe off some dust.


Washable Filters

One advantage of a washable filter is because it lasts longer than the one-time use variants. This saves you a lot of money especially if you use your vacuum often.

All you have to do is to clean the filter under running water and let it air dry. Just fix it back into the vacuum and you are ready to go again, and again.


Double Battery Option

It can be pretty annoying if the battery on your cordless vacuum runs out when you are just halfway into your cleaning. You have to wait for hours for the battery to charge back up.

Shark, being so proactive, came up with a variant of the Shark IONFlex that has 2 batteries. That way, you can keep one battery in charge while you work with the other.

All you have to do is swap batteries and continue vacuuming. Even with just one battery, you will still get up to 30 minutes of vacuuming time. That is about enough time for some decent cleaning.



Shark is quite generous to include some practical accessories along with the package. The crevice tool lets you clean into corners and baseboards. You can also get rid of cobwebs and dirt from floor gaps with this.

It also comes with a pet multi-tool which helps you get rid of pet hairs from floors and upholstery. The anti-allergen brush tool deep cleans any surface to get rid of dust and allergens to keep your sensitive occupants safe.



The User-friendliness Of The Shark IONFlex Cordless Vacuum

This cordless vacuum is lightweight making it easy for almost anyone to wield it around the floor. There is also nothing complicated about the controls as well.

To use the Flex function is as easy as pulling a lever and you can bend it like you want. You also just need to push a button to convert it into a handheld.

With the technology it features, vacuuming is fast as you won’t need too many passes to get the deep clean you want. And that is for any floor type.

This is not a vacuum you need to get used to. Everything you need to do on it is quite convenient and straightforward.
