Shark IONFlex 2X DuoClean Design
The Shark IONFlex 2X DuoClean has a basic stick vacuum design with a few extra design points.
What’s the main breakdown?
The Shark IONFlex vacuum includes the following components
- Handheld body
- Cleaning head
- Removable battery
While the design of this vacuum may seem more complex, it is actually quite simple:
As a stick vacuum, the Shark IONFlex simply snaps together. As a result, it has a standard stick vacuum configuration.
For example, you can remove the wand and main cleaning head, converting the Shark vacuum into a handheld. Once in handheld mode there are a variety of different attachments (see below).
The IONFlex is one of the coolest looking vacuums we have seen to date. The blue color scheme is sharp and gives this vacuum quite the sleek appeal when combined with the gray pops of color that Shark dropped into the vacuum.
How does the Shark IONFlex DuoClean vacuum work?
The Shark IONFlex vacuum works through a simple process. Two brushrolls are located within the main cleaning head and are used to agitate, lift, and remove dirt and debris from your floors.
Depending on the cleaning mode selected by the user, the IONFlex will change its suction power and brushroll speed. For example, on hardwoods the suction power is not as strong as on a carpeted surface, but the softer brushroll plays a large role.
That said, when placed in carpet cleaning mode, the multi-surface brushroll is the more important of the two brushrolls, as it works to dig deeper with a stronger level of agitation.
Size & Dimensions
The Shark IONFlex DuoClean vacuum is a bit taller than most other stick vacuums we have tested.
How big is the vacuum?
- 46” tall
- 13.4” wide
- 8.7 lbs.
Accessories and Parts
The Shark IONFlex DuoClean includes a few extra parts and accessories:
CREVICE TOOL | The Shark IONFlex includes a crevice tool which allows users to dig into the deeper corners and crevices of the home.
DUSTING BRUSH | A small dusting brush is also included, giving users the opportunity to dust and vacuum more delicate surfaces.
DUSTING WAND | Similar to the dusting brush, the dusting wand is good for capturing dust around your home. This tool is actually slimmer than the dusting brush, allowing users to dust harder to reach places.
CHARGER | A charging base is also included with the Shark. Remove the battery from the vacuum and attach it to the charging base as needed.
UPHOLSTERY TOOL | The upholstery tool is a combo tool that comes with firmer bristles and a removable face for a more versatile cleaning tool.
Shark IONFlex Features
The Shark IONFlex 2x Duoclean stick vacuum has a slightly different set of features than most stick vacuums.
Although a stick vacuum, this Shark does have the ability to switch into bare floor (hardwoods, tile, etc.) and carpet cleaning modes. By doing so, this vacuum is able to adjust its cleaning power and brushroll spin automatically when placed on the surface.
Additionally, the Shark IONFlex has two power modes, standard and MAX suction mode. As the name suggests, the MAX suction mode adds power to the degree of suction, offering a deeper level of cleaning.

Multiple Battery Packs
The Shark 2X IONFlex DuoClean vacuum includes not one, but two battery packs.
Therefore, users can be charging one of the battery packs while the other is being used. This is a major bonus as you shouldn’t have to worry about not having a fully charged battery during a clean.
That said, you should note that not all models include 2 batteries. The IF251 includes 2 battery packs. If you don’t want to pay extra for the 2nd battery you can get the IF205 model, which is the same vacuum, but only 1 battery.
While this vacuum is primarily used as a stick vacuum, it does have the ability to be turned into a handheld as well. Users can remove the main cleaning wand and cleaning head and attach a smaller cleaning tool, making it a handheld.
This is great for those users who are in need of a vacuum that can clean well on the floor, as well as spot clean around the home. With quite a few extra cleaning tools, the variety of cleaning styles is a really nice extra.
The cleaning performance of the Shark IONFlex DuoClean vacuum was incredibly strong on all cleaning surfaces.
Hardwood Floor Cleaning
The Shark IONFlex DuoClean performed well on the hardwood floor tests, but we did see a slight struggle with the sugar test.
Rice, kitty litter, and cereal were simply no match for the Shark IONFlex on our hardwood floor tests.
That said, the sugar test was a bit of a surprise. As we pushed the vacuum over the sugar the softer brushroll had a tendency to fling the sugar up on top of the vacuum’s cleaning head. This resulted in less of the sugar being cleaned up, but it was not a dramatic difference from the rest of the field.
Low Pile Carpet Cleaning
The low pile carpet test was similar to the hardwood, with similar issues for the sugar test.
How much of a change was this test?
Once again, rice and cereal were no match for the IONFlex vacuum.
Sugar dropped off a bit as compared to the hardwood floor test, going from 93% cleaned up to 90% removed. The difference was not huge, but it does mean 10% of the total sugar placed on the carpet did remain within the pile.
High Pile Carpet Cleaning
As we moved onto the high pile carpet, we saw the best cleaning performance yet.
What was the final outcome?
The Shark IONFlex was nearly perfect on the high pile carpet test. Rice, kitty litter, and cereal all hit 100% and sugar reached a level of 98% cleaned up.
This was a bit of a surprise after the hardwood floor and low pile carpet test.
That said, as we were working through the high pile carpet test, we noticed that this Shark vacuum increased its suction power on its own. Therefore, as we were pushing the vacuum across the carpet, the four debris types were not able to beat the Shark IONFlex as it increased its power and sucked up nearly every piece of debris sprinkled across the lane.
In the end, these were all results of the Shark IONFlex DuoClean 2x being used in stick mode. We did test this vacuum in handheld mode as well and found that as a handheld, the Shark was able to dominate our cleaning tests and pick up the remaining debris from the testing lane.
Usability & Maneuverability
Usability and maneuverability on the Shark IONFlex stick vacuum are fantastic.
Using this stick vacuum is fairly straightforward:
- Charge the vacuum’s battery packs
- Choose stick or handheld cleaning modes
- Insert the battery
- Turn on and select cleaning mode at the back of the vacuum’s main body
The setup is quick and painless. Once everything is removed from the box you will need to snap in the cleaning head and wand into the handheld portion of the vacuum.
After completing these steps, you can jump into 1-4 listed above and begin using the vacuum.
How’s the IONFlex maneuverability?
The Shark IONFlex vacuum is one of the most impressive stick vacuums we have tested to date, with regard to maneuverability.
As stated in the name, this Shark vacuum is flexible. At the middle of the main wand, there is a release button that allows the vacuum to bend at 90°, making it much easier to clean under and around furniture and other obstacles.
This is the first vacuum we have seen that contains the ability to do this, so it was neat to see the ways in which this vacuum can move around.

Lastly, the Shark IONFlex is a 2-in-1 vacuum. The vacuum can be convereted to handheld mode, making it perfect for spot cleaning, cleaning cars, or cleaning anywhere else that a stick vacuum doesn’t quite go.
Shark IONFlex Maintenance
There are a few tasks required by the user in order to maintain this Shark stick vacuum.
The following tasks need to be completed in order to properly maintain this vacuum:
- Replace the filter
- Clear both brushrolls from tangles
- Empty dustbin
Is the Shark IONFlex a good value?
The value of the Shark IONFlex 2x is excellent. It is a bit more spendy than some other stick vacuums we have tested, but it is also versatile, a strong performer, and includes two batteries.
With regard to cleaning performance, the overall score was great. There were some issues with our sugar test, but these issues were fairly minor and easily resolved by the handheld mode.
Maneuverability is certainly a strong suit of the IONFlex.
With the ability to bend 90° in the middle of the main wand (while in stick mode) and turn into a handheld vacuum is nothing shy of impressive.
This gives users tons of options when cleaning around their home.
In the end, this Shark stick vacuum is hard to beat. If you’re looking for a versatile stick vacuum with multiple battery packs, a strong cleaning performance, and a well rounded level of versatility, the IONFlex DuoClean 2x could be a nice addition to your home.

The Shark IONFlex DuoClean 2x vacuum could be a great fit for a wide variety of users. This vacuum can be used as both a handheld and stick vacuum and has a strong cleaning performance.

Instead of having a single battery and having to wait for it to charge, users can charge the second battery while using the first one and continue to swap back and forth.

Why did the Shark IONFlex stick vacuum score the way it did?
- Design – 2-in-1 design, flexible pivot of the handle, lots of accessories. The IONFlex does a lot right. One notably complaint is the way the cleaning head flings sugar.
- Performance – Not flawless, but pretty close.
- Quality – Easily the best Shark vacuum we’ve tested to date in terms of quality. Compares similarly to the feel of Dyson.
- Usability – again, 2-in-1 design and pivot handle are really nice. Lots of accessories and attachements also.
- Value – at about half the price of the Dyson V10, but only a little worse in terms of performance, the Shark IONFlex is an exceptionally good value.
