Shark IONFlex 2X DuoClean Cordless Ultra-Light Vacuum IF251 Review

Cordless vacuums are convenient. They give you the freedom of movement that upright vacuums simply can’t provide. Nonetheless, some cordless vacs are stick-only vacuums without a handheld function while others are handhelds that don’t have a floor nozzle. Those limited to floor use are often geared toward either carpets or bare floors, and many can’t reach under furniture. Plus, every cordless vacuum runs off battery power, so you aren’t able to use the vacuum when the battery is charging. However, there is one cordless vac that eliminates all these problems – the Shark IONFlex 2x DuoClean Cordless Vacuum.

Shark IONFlex 2x DuoClean Cordless Vacuum IF251 Review

The IONFlex 2x DuoClean Cordless Vacuum gives you the ability to clean your floors, car, shelves and more with its ability to convert from a stick vac to a handheld vacuum and its addition of several helpful attachment tools.

It also has two types of brush rolls that work together to clean carpets and hard floors, and you can even customize the surface and suction settings to meet your specific cleaning needs. With its bendable wand, you can vacuum underneath furniture and easily store the appliance. This cordless vac comes with two batteries, so your stick vacuum will always be charged and ready to go at a moment’s notice.

Easy Versatility and Maintenance

With just one touch of the release button, you can detach the handle and canister from the wand and floor nozzle, instantly turning the floor vacuum into a handheld vac. This allows you to clean everywhere around your house, including ceiling fans, door frames, cabinets and mantles.

Plus, the handheld feature works great for automobile detailing. With the wand attached, the vacuum only weighs 8.6 pounds, making it light enough for you to maneuver without straining yourself.

The dust cup is just as easy to open. After pressing the wand-release button, you can carry the cup to the garbage can and open the bottom lid with the cup-empty button. To cut down on the dust particles floating through the air, the IONFlex is even equipped with washable pre-motor and post-motor filters.

DuoClean Brush Technology

On this cordless stick vacuum, there are two brushes. A strong-bristled brush is able to reach deep into carpet fibers in order to bring dirt and debris to the surface, so the vacuum’s suction nozzle can pick them up. There is also a soft-textured brush that not only draws in large debris but also lightly polishes hard floors. Since they operate in unison, you get the benefits that both brush rolls provide no matter what type of floor you’re cleaning.

The IONFlex also has a brush roll indicator light that glows green when the brushes are in working order and red when they are jammed, so you know right away if they need to be cleaned, saving you the time that you would have spent on troubleshooting. Removing the brush rolls is an easy task. Simply slide the two door-access buttons and pull the tab to release the brushes.

Smart Response Performance

Every floor material requires a different level of care. Therefore, Shark integrated its Smart Response technology in order to give you the ability to adjust the vacuum’s power settings. From the display panel, you can choose from among two surface settings and two suction settings. Make the brush rolls spin faster for high-pile carpeting with the carpet setting or slower for hard surfaces with the hard floor setting.

You can also control the suction strength. The extended run-time feature is perfect for daily cleaning, and it doubles the battery life between charges.

On the other hand, the max power function is suitable for situations when heavy-duty vacuuming is necessary. In extended runtime mode, you can get about 23 minutes’ worth of vacuuming time before the battery must be recharged.

MultiFLEX Wand

The MultiFLEX wand is a feature that is unique to the IONFlex cordless vacuum. This technology allows the wand to bend in the middle. With just a single press of the unlock button, the hinged cover opens up and reveals a bendable hose.

You can utilize the flexible wand to extend your reach when you clean underneath furniture. It can also fold in half, allowing you to store the freestanding vacuum in small areas.

When you are ready to return the wand to its upright position, pull the handle until the hinge locks into place.

ION Power Pack Battery System

One of the most frustrating aspects of using a cordless vacuum is having to stop a cleaning session to wait for the battery to recharge. With the two ION Power Packs, you get twice the length of vacuuming time without battery-life restrictions as well as a 2-year warranty if one of them fails prematurely.

Both of the power packs come with a rechargeable 25.2-volt lithium-ion battery and a charging dock. You can charge both batteries at the same time or use your vacuum while the other battery is waiting to be swapped.

Each power pack is equipped with a battery light indicator, so you check its status at a glance. For a 100-percent depleted battery, the charge time is 3.5 hours.

Attachment Tools

Only the best cordless vacs come with attachments, and Shark vacuums are definitely top-notch products. With the IONFlex 2x DuoClean, you are given three attachment tools to make cleaning easier and more efficient.

There is a duster-crevice tool. This 8-inch combo attachment features soft bristles to help you dust and a tapered nozzle made to fit in narrow spaces. To go from brush to crevice, simply slide the duster head.

In addition, the vacuum comes with an anti-allergen dust brush, which works well for removing fine dust from decor objects.

If you’re a pet owner, you’ll appreciate the multi-tool that can not only lift piles of debris but also remove hair from fabric.
