Shark IONFLEX 2x DuoClean Vital Statistics

  • Weight: 3.8 lbs 
  • Dust Cup Capacity: 0.3 dry quarts
  • Battery Run Time: 11 minutes on Max Power mode, 23 minutes on Extended Runtime.

Impressive runtime 

The 2X in the product’s name is referring to its special battery component - one of the major advantages of this cordless Shark vacuum is indeed the two ion battery packs. These lithium-ion batteries are the latest technology and provide a long run time considering the strong suction power.

Also, because you can swap the batteries out for the spare you can get more cleaning done in one go compared to other cordless models with a single battery. If you forget to charge the battery the night before you have guests, you can make sure there is always one on the charging station. 

This feature may make the Shark IONFlex 2X more attractive than the Dyson V8 to some, which only has a single battery that cannot be removed.

Cordless and convertible 

In addition to this vacuum being a power house, it also comes without the hassle of cords. That means that you can maneuver around the house without having to worry about your vacuum cord snagging on the couch or dinner table. You also won’t have to worry about plugging it into a new outlet when you’re ready to move on to the next room. The product as a whole is lightweight, so if you need to get in a space that is high up, you won’t strain your back in the process.

Additionally, the Shark IONFlex 2X can be converted into a handheld vacuum. It is easily detachable from its body if you want in between the couch cushions or on individual steps. Since it runs on batteries, you can also bring this vacuum outside to clean the inside of your car.


This vacuum is designed to clean a variety of flooring, from hardwood to carpet. It is equipped with different features to tackle particles on multiple surfaces without the need for additional attachments.

Whether you want to give your carpets a deep clean or give your hard floor a polished look the DuoClean Technology was designed for either surface. There are two brush rolls in the IONFlex 2X DuoClean head unit: a bristle brush for carpets and an additional soft brushroll to pull in larger particles and directly engage floors to give a polished appearance.


Thanks to the flexible design of this product, you can get into tight spaces that might otherwise require you to move furniture.

It comes equipped with a bonus Under-Appliance Wand, allowing you to reach underneath your stubborn kitchen appliances. It has been said to “turn on a dime,” letting you pivot around the area you are cleaning with minimal effort.

The Shark IONFlex 2X DuoClean can also be folded over when you’re finished cleaning. Comparable products take up more space and don’t have freestanding capability.

Duster crevice tool

Larger vacuums typically don’t have the reach or ability to clean in tight, awkward crevices. You’ll no longer have to get down on your hands and knees when you want to dust the baseboards in your home – this Shark has got you covered. Its dual-purpose will also allow you to clean the blinds without leaving lines of dust behind.

Pet and Allergy Friendly

The Shark IONFlex 2X DuoClean comes equipped with special tools for pet owners and allergy sufferers. There are two features of this vacuum meant to tackle animal hair, depending on your pet’s level of shedding: a bristle brush and an extra upholstery tool. The bristle brush can be easily detached to access the upholstery tool.

Additionally, you can upgrade your package to include the anti-allergen dust brush. Although this option is a bit more expensive, it will keep remove unhealthy particles from your home that could trigger an allergic reaction.


The dust bin is located on the top of the handle near the battery pack. Although it is fairly small (0.3 quarts), it does not require a lot of effort to empty out. No vacuum bags are required to use this product, saving you from a reoccurring cost in the future.

  • Individual battery life is limited on high speed: Some consumers have noticed that having this vacuum on the highest speed for too long drains the battery quickly. This shouldn’t be an issue if you always remember to keep your spare battery charging. If this doesn't provide enough runtime for you then a corded lightweight vacuum might be more suitable for your needs. We like the lightweight Shark Rocket DeluxePro, which we reviewed in our Best Lightweight Vacuum Reviews.

    Batteries can take approximately half an hour to cool down prior to charging after use. The charger indicates via a double blue light warning if the batteries are too hot. However, if you simply leave the batteries in the charger it will start charging them once they are cool enough.
  • Potential clogging: The handle of the vacuum may get clogged if you are trying to pick up too many small pieces at once – especially hard materials like plastic.
  • Top heavy: Although this vacuum is freestanding, this feature is only possible when it is folded over. Keep this in mind if you take a break during cleaning.
  • Small dust bin: Since this model is so lightweight, the dust bin on the top of the handle isn’t very large. On the plus side, it is very easy to detach and empty out. Just make sure you keep a bag or trash can nearby if you’re planning on cleaning a particularly large space.
