Shark is making a big splash in the cordless vacuum cleaner market in 2020 with the IONFlex 2X Duoclean Ultra-Light stick vacuum. This model has many great features that you’d expect to find on a more expensive cleaner, but it’s still one of the best-priced cordless vacuums available on Amazon today.

This Shark vacuum will last longer on a single charge than most cordless vacuums in its class and the 2X in its name will give you an idea why. It’s equipped with 2 lithium-ion batteries and that means it will run twice as long as the average cordless stick vacuum cleaner on one charge. It’s just one of the many great features of the IONFlex 2X, which we’ll explore further in our review below.

An Overview of the Shark IONFlex 2X

The Shark IONFlex 2X is a cordless stick vacuum that comes with many of the impressive features you’ll find on corded Shark vacuums such as the Shark AZ1002 that we’ve also reviewed at Spotless Mag. You can remove the canister from the main stick to use it as a handhold vacuum on stairs, curtains, and upholstery. It also comes with Shark’s impressive DuoClean brush system which is designed to pick up just about anything. 

It’s important to keep in mind that this is a cordless vacuum – it’s just that Shark has managed to remove the charge limitations usually associated with these vacuums with its 2X system. The machine comes with two separate lithium-ion batteries so that you can be “always charging” as you clean. They easily slot into place and Shark provides a standalone charger that the spare battery can charge on as you clean.

The IONFlex 2X is Designed with the User In Mind


In our review of the SharkIonFlex 2X, we found it ticked just about every box when it comes to user-friendly design. You can easily change the modes of this machine for every cleaning situation. The suction speed and power can be changed to match the surface you’re cleaning and you can take advantage of Shark’s MultiFLEX technology to reach under furniture without bending. The IONFlex 2X can also be transformed into a handheld device when you need to. 

The brush head on this Shark vacuum swivels and pivots to bend around chair legs and tables. In the vacuums we’ve reviewed, we always rate a product higher when it has this kind of flexibility. The IONFlex 2x is one of Shark’s most versatile products.

We don’t have many complaints with the 2X, but the MultiFLEX feature can take some getting used to – it may feel a little awkward at first. Once you get the hang of it though, it’s hard to imagine living without it. It helps that it weighs in at just 8.7 pounds.

The other advantage of the MultiFLEX mode we found in our Shark IONFlex 2X cordless vacuum review was that it makes the product easier to store. You can use this feature to fold the vacuum in two for storage in any small closet.

Like most Shark products, the 2X comes with a range of standard attachments. The main DuoClean brush system is probably the one you’ll use the most, but it also comes with a crevice tool, pet multi-tool, an under appliance wand, an anti-allergen dust wand and of course 2 lithium-ion batteries. It’s easily one of the most complete cordless vacuum cleaner systems we’ve reviewed at Spotless Mag.


Performance Features of the Shark IonFlex 2X

Powerful Suction – The IONFlex 2X may have the best suction of any cordless vacuum cleaner on the market in 2020. It can maintain its powerful suction for up to 50 minutes of continuous cleaning with just a short break to swap batteries. You can also adjust the suction to match the surface you’re cleaning with a flip of a switch – speed up the suction for carpet and slow it down for hard surfaces. It’s important to remember to have the back-up battery charging as you go through, as it does take 3.5 hours to charge a drained battery.

Pet Hair and Large Particles – The DuoClean brush turns the IonFlex 2X into a versatile cleaner that’s just as good at picking up fine particles and hair as it is at collecting large particles. The only thing that will slow you down is the relatively small dust bin capacity of this machine at 0.3 quarts.

HEPA Filter and Complete Seal Protection – In our Shark DuoClean IONFlex 2X reviews we were impressed with the filtering technology built-in to this machine. It uses a HEPA filter with Complete Seal protection that not only collects up to 99.9% of all dust and allergens, it also makes sure it remains sealed in the vacuum and doesn’t get pushed back out into the air. 

MultiFLEX Technology – The flexibility of the IONFlex 2X was one of our favorite features of this vacuum. The MultiFLEX technology makes it easy to reach under objects to clean without bending and it makes it easier to store the machine when not in use in compact storage areas.

Noise Reduction – In our Shark IONFlex 2X DuoClean cordless vacuum review we were surprised at how quiet this vacuum was. It operates at slightly more than 76 decibels, which is quieter than most standard vacuum cleaners. 

Durability of Design of the Shark 2X

For a flexible and versatile vacuum cleaner, we were impressed with its durability in our Shark IONFlex 2X review. The hose bends easily, but it doesn’t feel flimsy or fragile to the touch. All components of the body are made from injection-molded plastic and the brushes are designed to last through many uses. If you do need replacement parts they’re easy to find at some of the best prices on Amazon as well.
