Dyson V8 cordless stick vacuum cleaners vs Shark IonFlex 2X DuoClean (IF25x & IF26xUK)

Analysis:

The Dyson V8 Absolute makes for an outstanding Stick Vacuum Cleaner at $499. The Shark IonFlex 2X DuoClean (IF251), however, while overall a good product for its asking price, doesn't quite manage to stand out from its competition - there are better Stick Vacuum Cleaners that can be found for around $300 available here.

Two highly trusted sources that perform well-thought-out in-depth testing consider the Dyson V8 Absolute to be a great product - it earned the "Top Pick" title from Wirecutter (NYTimes) and "Ranked 3 out of 12" from TechGearLab in their respective Stick Vacuum Cleaner roundups, which is a good indication of it being a notable product.

Moving on to the Shark IonFlex 2X DuoClean (IF251): it was loved by Reviewed and Techradar - two reliable sources that conduct their own in-depth testing. In fact, it was named "Ranked 3 out of 6" and "Ranked 3 out of 8" in their respective roundups, which points to it being a product worthy of consideration.

To get a better idea of how they fare when compared directly to each other, we analyzed review scores of sources that tested both. Expert Reviews and TrustedReviews, for example, preferred the Dyson V8 Absolute, while Modern Castle rated both of them the same.

We also took a look at which sources had the best things to say about them. We learned that the Dyson V8 Absolute got reviewed the highest by T3 - it gave it a rating of 10, while the Shark IonFlex 2X DuoClean (IF251) most impressed reviewers at Modern Castle, which gave it a score of 9.6.

Lastly, we averaged out all of the reviews scores that we could find on these two products and compared them to other Stick Vacuum Cleaners on the market. We learned that both of them performed far better than most of their competitors - the overall review average earned by Stick Vacuum Cleaners being 8.0 out of 10, whereas the Dyson V8 Absolute and Shark IonFlex 2X DuoClean (IF251) managed averages of 8.9 and 8.9 points, respectively.

Due to the difference in their prices, however, it's important to keep in mind that a direct Dyson V8 Absolute vs. Shark IonFlex 2X DuoClean (IF251) comparison might not be entirely fair - some sources don't take value for money into account when assigning their scores and therefore have a tendency to rate more premium products better.
