The value prop

The Shark IONFlex 2X DuoClean cordless vacuum cleaner is by far one of the most powerful vacuums on the market right now. With a compact design, multiple suction settings, and accessories to target pet messes and fine debris, this vacuum is a great choice for people who desire a machine for everyday cleaning.

Pros
  • It easily converts into a handheld vacuum for better portability.
  • It has MultiFLEX technology, which enables the vacuum to fold over for compact, free-standing storage.
  • It features LED headlights on the cleaning head, allowing you to see fine messes.
Cons
  • It doesn’t come with a HEPA filter.
  • It has a small dust canister.

Shark IONFlex 2X DuoClean design

This stick vacuum is one of the lightest vacuums available and comes in a metallic blue color. It has two LED lights on its head that give you a more precise cleaning experience and MultiFLEX Technology that allows the vacuum to fold for compact storage. This technology also provides flexible reach to get under beds, couches, and tables.

If you’re looking for a two-in-one vacuum, the Shark IONFlex 2X DuoClean is a clear contender. One of our favorite features of this stick vac is that it can convert into a portable vacuum, allowing you to clean your car and other hard-to-reach places. It also has a power button that can be pushed once to activate and power the device—unlike Dyson sticks, no holding down on a trigger is required (this is a huge advantage, especially if you’re cleaning a vehicle).

Some other important design features of the Shark IONFlex 2x DuoClean include:

  • Smart Response Technology—This technology provides a range of performance-enhancing power settings tailored for your cleaning needs on carpets and hard floors.
  • A DuoClean tool—Combining a soft roller bar and a bristle brush into one cleaning head, this hybrid tool enables cleaning of fine dust and debris on both carpets and floors with fewer nozzle passes.

Vacuum assembly

Don’t worry about spending too much time assembling this cordless vacuum. Simply insert the wand into the motorized floor nozzle connector and then insert the handheld vacuum into the top of the wand until you hear a click. Before vacuuming, make sure you insert one of the lithium ion batteries into the handheld vacuum.

How the Shark IONFlex 2X DuoClean cleans

The Shark IONFlex 2X DuoClean vacuum cleaner is by far one of the most powerful vacuums on the market. During our suction tests, we were amazed at its power and ability to pick up substances on hard floors and carpet. With DuoClean Technology, this vacuum cleaner is able to roll over large debris and deep clean carpets to give your floors a more polished look. Even big items like Cheerios were no match for this powerful stick vacuum.

It has two surface settings: carpet and floor. On the carpet setting, both brushrolls spin faster to pick up deeply embedded dirt from carpets. On the floor setting,  the brushroll and Soft Roller both spin together to gently clean the floor. The Soft Roller traps fine dust and larger particles while the brushroll pushes debris to the suction channel.

In addition to the two surface settings, the Shark IONFlex has two suction settings: extended runtime and max power. Extended runtime is the lowest setting and is meant for everyday cleaning while max power is the highest setting meant for heavy duty cleaning and tackling stubborn messes.

This Shark cordless vacuum comes with 25–30 minutes of uninterrupted power, allowing you to clean your entire home or vehicle in one go. And if your battery happens to run out while cleaning, this Shark comes with two battery packs that allow you to charge one battery while using the other. If the battery you’re using dies, simply swap it out with the charged battery and continue your cleaning job.

What to note about the Shark IONFlex 2X DuoClean

When emptying the dust bin, pet hair and other fine particles may get trapped, requiring you to remove some of the contents manually. The dust cup is also quite small, so you’ll have to empty it frequently if you’re planning on vacuuming larger areas of your home. If you’re looking for a stick vacuum with a larger dust cup, we recommend the Dyson V8.

Dimension Measurement
Height 45.98 inches
Length 13.43 inches

Accessories included with the Shark IONFlex

This vacuum cleaner comes with two ION Power Pack batteries, a duster crevice tool, a pet multi-tool, a double charging dock, and a charging cord. If you want to use the DuoClean for cleaning the inside of your vehicle, consider buying the Complete Car Detail Kit, which includes a battery pack, a charger, a precision duster, and an 18-inch crevice tool. 

Batteries

The removable and rechargeable batteries allow you to vacuum with one battery while the other battery charges, so you never have to stop and charge in the middle of your cleaning job.

Duster crevice tool

The duster crevice tool is two cleaning tools in one: the crevice tool gives you extended cleaning reach for small spaces while the dusting brush cleans a multitude of surfaces by agitating dust and other small particles, which are then picked up by the strong air flow into the vacuum cleaner.

Pet multi-tool

The pet multi-tool is designed for cleaning tough pet messes. It also features two tools in one: The stiff bristle brush removes stuck-on debris from surfaces and if you detach the bristles, you’ll reveal an upholstery tool meant for cleaning stubborn pet and human hair from furniture and other surfaces.

Cleaning tests

We performed three different tests that measured suction power, maneuverability, and mobility on hard floors, low-pile carpet, and high-pile carpet. For our suction tests, we used Cheerios, kitty litter, coffee grounds, and pet hair.

Cleaning score: 9.33/10

Test 1—Suction test on hard floors

When testing the Shark IONFlex with DuoClean on hard floors, we gave it a perfect score for removing all substances. It had no problem sucking up Cheerios, kitty litter, coffee grounds, and pet hair in a single pass. When using this vacuum on hard floors, we set it to the floor setting, meant for bare floors and area rugs.

Test 2—Suction test on high-pile carpet

For cleaning high-pile carpets, we recommend leaving this cordless vacuum on the carpet setting. Both brushrolls spin faster, working together to pick up debris from carpets. On this setting, the Shark did an amazing job at picking up all four substances. It sucked up the Cheerios and pet hair in one pass and removed the kitty litter and coffee grounds in three passes.

Test 3—Suction test on low-pile carpet

When testing the Shark IONFlex 2X DuoClean on low-pile carpet, we set it to the floor setting. On this setting, the vacuum removed the Cheerios in one pass, the pet hair in three passes, and the kitty litter in five passes. It took more than seven passes to completely remove the coffee grounds. However, when we changed the suction power setting to max power, the vacuum did a much better job at removing the substances and sucked everything up in two passes or less.

Which is better: the Shark IONFlex 2X or the Dyson V8?

Shark and Dyson are some of the most trusted vacuum brands in the industry. Both provide exceptional stick vacuums with similar design features and price points. Here’s a side-by-side comparison at both of these vacuum cleaners. The biggest differences to note are that the Shark IONFlex has a shorter run time, larger dust bin capacity, and wider cleaning path.

Maneuverability

Compared to other cordless vacuums, the Shark IONFlex with DuoClean is easy to maneuver and allows you to vacuum without having to worry about your cord snagging on furniture. When we tested its swivel steering around a couch and underneath a coffee table, it received a perfect score.

Usability

Not only is the maneuverability fantastic on this vacuum, but its mobility is also just as great. It never got stuck on either type carpet and moved effortlessly on hard floors. It’s also incredibly easy to transform into a handheld vacuum.

Noise

This vacuum cleaner measured 76.2 decibels, which is less than the average noise level of a standard vacuum. Compared to other stick vacuums, this Shark vacuum is just as quiet, if not quieter.

Shark IONFlex 2x DuoClean maintenance

The Shark IONFlex 2X DuoClean is very easy to empty. We recommend emptying the dust cup when debris reaches the MAX fill line.

  1. Press the Wand Release button on the top of the wand to disconnect the handheld vacuum from the wand.
  2. Hold the dust cup over a trash bin and press the Empty button. The bottom lid will open, allowing the debris to fall out.
  3. Once the dust cup is empty, close the bottom lid and insert the handheld vacuum back into the wand.

Note: Pet hair and dust can get stuck in the vacuum cup and may have to be removed with your hands.

Filtration

The Shark IONFlex 2X DuoClean comes with a pre-motor (foam and felt) filter kit and a post-motor exhaust filter. The pre-motor foam and felt filters should be cleaned once a month with cold water and dried for 24 hours before being inserted into the vacuum. The post-motor exhaust filter should be rinsed and air dried once every nine months. Between washings, the filters can be tapped clean to remove excess dust and particles.

Note: This Shark doesn’t come with HEPA filtration, so if you have allergies and don’t want to inhale allergens or dust, we recommend going with the Dyson V8.

Warranty

The Shark IONFlex 2X with DuoClean vacuum offers a five-year limited manufacturer’s warranty and a two-year limited battery warranty. Under the five-year manufacturer’s warranty, the original unit and/or non-wearable components deemed defective will be repaired or replaced for up to five years from the original purchase date.

Under the two-year battery warranty, the original ION Power Pack, deemed defective, will be replaced for up to two years from the original purchase date. To initiate a warranty claim, you can call 1-800-798-7398 and speak with a customer service associate for assistance.

Is the Shark IONFlex 2X DuoClean a good value?

You can’t go wrong with the Shark IONFlex—with incredible versatility, powerful suction, an array of helpful cleaning tools, and a competitive warranty, this vacuum is a great choice for daily home and vehicle cleaning. Though this portable vacuum comes with a higher price tag than other Shark vacuum cleaners, you get what you pay for. With its modern technology, the Shark IONFlex 2X makes cleaning your house and vehicle less stressful and is worth every penny.

Who should buy the Shark IONFlex 2X?

We recommend the Shark IONFlex 2X DuoClean if you’re looking for the following:

  • A compact vacuum—With MultiFLEX technology, this Shark cordless vacuum can fold over for compact, free-standing storage, requiring minimal space. This makes it a great option for those who live in small homes and apartments.
  • A range of power settings—With two surface and suction settings, you can get a more precise clean on various surfaces like carpets, rugs, bare floors, and upholstery.
  • A long battery life—Two batteries mean double the run time. Charge one battery while using the other to ensure that your entire home gets clean in one go-around.

Customer reviews

I am SO excited about this little vacuum! I was really skeptical at first—it was a lot of money, but the reviews appeared to be good. I just received mine yesterday and had it set up by myself and both batteries charged before I went to sleep. Today I’ve used it around the house and it was perfect! [It was] light and picked up all the little pieces of dirt and lint. I bought it specifically for my hardwood floors. I needed something that would not scratch the floor (they are brand new) and would pick up the little crumbs, dirt, lint, etc. that show up on the floor. Something quick and easy. And this definitely was quick and easy! It maneuvers well on the hardwood and my area rugs. I am SO happy! Highly recommend 🙂” — Amazon review

After only 6 months of ownership, the model I purchased from here had the motor dying out and wouldn’t clean anymore. I happened to talk to a Shark rep through a Facebook post and was able to send it straight to Shark and get a brand new one. That one works great so far.” — Amazon review
