The direct answer to the question What is the difference between the Shark IonFlex vs. IonFlex 2x is that both Shark cordless stick vacuums are the same in terms of design and performance, except that the IonFlex 2X has one more battery pack.

The Shark® IONFlex 2X DuoClean® Cordless Stick Vacuum can run up to 60 minutes when using 2 battery units as compared to the Shark® IONFlex DuoClean® Cordless Vacuum.

Introducing the Shark® IONFlex™ Cordless Ultra-Light Vacuum.

When shopping for either of these vacuums, you may come across a variety of model numbers such as IF252, IC205, IC205CCO, IF200, IF200C, IF200W, IF201, IF202, IF203Q, IF205, IF251 and IF251C which are different vendor identification numbers and/or newer variations.

Both of these are older Shark stick vacuums, but you can still find them on sites like Amazon new, used and certified renewed. Before making a purchase, we do recommend taking a look to see if there are any sales on newer models. This may get you a vacuum with better technologies for the same or similar price.


Pros and cons of Shark IONflex

What We Like…

  • 2 battery packs. You can run up to 60 minutes and do not need to wait for the charging time.
  • Duoclean brush roller. This brush roller is the best design for picking both larger particles and finer dust. The Duoclean is one of the greatest advantage of Shark over other competitors.
  • Strong suction, comparable to the Dyson V8 model.
  • You can use as a stick vacuum a handheld vacuum for cleaning from top to bottom. The under-appliance wand is useful for reaching under table, bed, sofa.
  • A lot of attachments: Duster crevice tool, Anti-allergen dusting brush, Pet multi-tool, MultiFLEX under appliance wand.
  • Pet hair cleaning capacity
  • 5 years warranty

What Could Be Better…

  • A bit heavy. The whole unit is 8.7 lbs, which is much higher than Dyson (5.85 lb typically). When using as a floor vacuum cleaner, it does not have any issues. However, when transforming into a hand-vac, Shark IONflex is top-heavy and can cause fatigue.
  • No HEPA filters. If you have asthma, we highly recommend you to pick Dyson V8 to ensure the air quality.
