Shark IONFlex Duo Clean Review: Duo Clean Now is Cordless!

A few months ago I published a review that talked about the Duo Clean Rocket that featured Shark’s latest technology called the “Duo Clean” that features a roller brush and a bristled brush.

Shark IONFlex DuoClean Review

It was one of their first products that used this feature and had a similar design to the Dyson cordless vacuums.

The only difference is the Rocket has a cord.

Now Shark has a proper cordless vacuum that may rival Dyson in terms of versatility and performance.

Meet the IONFlex Duo Clean – Shark’s latest cordless stick vacuum to hit the market.

And it has several features not even found in the Dyson V8.

It’s probably the only stick vacuum with a trigger design that free-stands. Other vacuum cleaners like the Hoover Cruise, Dyson V8, V6, Shark Rocket, Bissell Multi Reach does not free-stand.

A quick look at the features

  • MultiFlex technology allows this to reach deeper into furniture because of the flexible extension wand
  • Of course, there’s the Duo Clean feature that cleans large and small debris on carpet and bare floor without the need to switch anything
  • It has two removable lithium-ion batteries so that you can charge one battery while still using the other
  • The versatile toolset that includes a duster crevice tool, pet multi-tool, anti-allergen dust brush, and a flexible extension wand
  • LED Headlights
  • Smart Response Technology that has different settings tailored for carpets or bare floor
  • Comes with a 5-year limited warranty

Pros

  • Versatile stick vacuum that morphs into a hand vac
  • Duo Clean feature is a game changer in how well it cleans bare floor and carpet
  • Extended 5-year warranty – 3 years longer than the Dyson V8
  • The flexible wand allows it more maneuverability and reaches under furniture
  • Removable battery means batteries can be replaced just in case it breaks
  • LED headlights give it better visibility

Cons

  • Small capacity dust cup
  • It takes around 3.5 hours to recharge
  • Not as maneuverable as the V8

What to expect from the IONFlex Duo Clean cordless?

This vacuum is similar to the Rocket Duo Clean minus the cord. In typical Shark fashion, they’ve added lots of goodies and features that make this stand out from its peers.

Before I go on babbling, please watch this video from Shark to see what this product is all about…

The features shown in the video is quite impressive from the Duo Clean system to the LED headlights.

There are two versions of this vacuum in Amazon – the IF251 and IF201. Both have the same features; the most significant difference would be that the IF215 (blue) has two batteries while the IF201 only has one.


Both will have the same Duo Clean tool with LED headlights and the flexible wand.

Duo Clean

Shark was the first and perhaps the only manufacturer that utilizes counter-rotating brushes. Instead of using two bristled brushes, the front part utilizes a soft roller brush that does a great job of pulling up dirt.

The second beater bar has a traditional bristled design to agitate dirt on the carpet.

Using this design allows Shark to raise the clearance and prevent snow plowing large particles of dirt.

It’s a fixture in all their new products that includes the Rocket and Rotator series vacuums.

Lithium-Ion Battery

The IONFlex comes equipped with a lithium ion battery that will give you around 20 to 30 minutes of run time depending on the power mode you use.

If you opt for the more expensive IF252, you’ll get not one but two batteries. Take note that this vacuum has an external charger so you can still use it while the other battery charging.

You can also plug it directly on the vacuum itself to charge when not in use.

Self-Standing feature

One thing that limits the Dyson V8, Hoover Cruise, Shark Rocket and other similar vacuums would be their inability to stand without a wall mounted bracket.

In my home with concrete walls, I don’t want to drill holes, but that’s just my preference. It isn’t a big issue for folks who don’t mind a little DIY work, but if you don’t want to drill any holes, this is a big plus.

Small footprint

Because the wand folds, it’ll take less real estate to store this vacuum. You’ll be able to stow this vacuum away easily.

MULTIFLEX technology

Before the IONFlex came out all of the vacuum cleaners in the Dyson mold used an extension wand that did not bend. While there’s nothing wrong with this setup, you’ll have to crouch down to reach deep under furniture.

Shark brings another innovative feature called the MULTIFLEX where a part of the extension wand flexes. It gives it better maneuverability when it comes to cleaning areas under tables or sofas.

LED Headlights

Another feature not found in other cordless stick vacuums is the LED headlights. You’d have to purchase a high-end upright to enjoy this feature.

Now it’s available in this vacuum.

It his helps in terms of visibility and tracking down dust.

Floor to ceiling versatility

Perhaps the greatest strength of this product is the versatility that it brings to the table. When you combine all the tools, you have a vacuum capable of cleaning every part of your home and even your vehicle.

It comes with: dusting brush, crevice tool and a pet multi-tool that will help you clean every nook and cranny of your home.

The pet multi-tool is handy when cleaning fabric sofa and mattresses. If you have children suffering from eczema, this is a handy tool that’ll help you clean bed bugs.

Bare floor cleaning

The most significant benefit you’ll get from the Duo Clean system would be how it cleans bare floor.

The Duo Clean design will funnel dirt towards the inlet.

Using this allowed Shark to raise the clearance thus preventing it from pushing larger bits of dirt forward- a phenomenon known as the snow plowing effect.

In a way, the soft roller part of the Duo-Clean system is similar to Dyson’s soft-roller but not as thick.

It will work great on most bare floor surfaces such as hardwood, tile, and linoleum. Even if it has crevices, there’s enough suction and agitation to pick up dirt trapped in those areas.

Carpet cleaning

If you’ve read my reviews about the Shark Rocket with Duo Clean and Rotator Powered Lift-Away, you’ll notice that I shared videos on how the Duo-Clean brushes perform and it performs well.

Take note the vacuum cleaners with a cord has more power.

But it’ll still have better performance when you compare it to other underpowered stick vacuums in the market. Dare I say that this will go head to head with the Dyson V8 in terms of how it cleans dirt and it’ll last more than 8 minutes even with the max power engaged.

Upholstery cleaning

This vacuum comes with a pet turbo brush; this vacuum is capable of cleaning debris like crumbs of chips or pet hair off fabric upholstery like sofa and mattresses.

If I could nitpick though, this tool does not pivot so it’ll put a bit of strain on your wrist.

Nooks and crannies

It also comes with a crevice tool so cleaning nooks and crannies should not be an issue.

See it in action

Here’s a real-world demonstration of how the Shark IONFlex works.

Take note that these may not be the same variant you’ll see in Amazon, but it’ll have the same motor and Duo Clean head.

What do consumers say?

Looking at reviews, consumers like how this product performs.

One review said that this vacuum has a “self-propelled” feeling on carpet.

It is good in my opinion because you know that suction is good and bad because it makes it harder to maneuver.

In terms of performance, it seems that this vacuum outperforms the Dyson V6 thanks in large part to the Duo-Clean system that has very good agitation in bare floor and carpet.

One thing to note is that Shark weighs more than the Dyson V6 or V8 because of the bigger motor and wider cleaning head.

It won’t be as easy to maneuver, but it still has the swivel steering.

Run time based on reviews is between 20 and 30 minutes depending on the cleaning mode. If you use the carpet mode, run time will be closer to 20 minutes.

The self-standing feature also got a lot of thumbs up, and since you can fold the wand, this lessens the footprint and requires less space to store.

Complaints include the dirt bin being small and some complaints about the long charge time that’s around 3 to 3.5 hours. Recharge time is pretty standard – take note that the Dyson takes the same time to charge fully.

Where can I buy this?

You can buy the Shark IONFlex from Amazon, and it currently has two variants – the IF201 and IF250. The IF201 only comes with one battery while the IF250 comes with two.

It’s also available from SharkClean.com if you want to buy it directly from the manufacturer.

One reason I like buying appliances from Amazon will be the availability of the extended warranty if you want extra peace of mind.

To wrap up

Shark does it again with the IONFlex Duo Clean. Think of this vacuum as a Shark Rocket without the cord.

Again, Shark has its eye set on challenging Dyson as the market leader in the cordless vacuum niche with never before seen features in a cordless stick like the MULTIFLEX technology, LED headlights and self-standing storage that does not require any brackets.

It’s a bit pricier than the corded Rocket but it does not have any cords, so this is a great versatile cleaner that’ll clean anywhere inside your home and vehicle.

  1. HOW DO I REMOVE ThE DUST CUP/? CAN I DOWNLOAD A COPY OF THE MANUAL?

  2. My vac will not stay on. It turns on and then the carpet and floor lights flash on and on then goes off. The battery is full. I clean the brushes and the vac is cleaned.

  3. I have this vac, and first thing I did was use it as a hand held to clean my car. It didn’t have much suction and both batteries combined use was less than 10 minute on full charges, . A friend bought this and used it on her hardwood floor and it didn’t work well for her so she gave it to me to try, I (we) are not happy with this product. Do you hve any suggestions on what we might be doing wrong, or is this defective?
