Roborock S4 vs Roborock S5/S5x

Analysis:

The Roborock S4 was loved by reviewers at Wirecutter (NYTimes), a highly trusted source that performs reliable in-depth testing. It did great in its "The Best Vacuum Cleaners" roundup where it was named its "Also great", which, in itself, makes it a product worth considering.

Returning to the Roborock S5/S5x, it managed to impress reviewers from two sources that are considered to be some of the most highly trusted on the internet, thanks to their in-depth hands-on testing - TechGearLab and PCmag. It performed great in their respective Robot Vacuum roundups - it was named "Best Navigational Abilities" by TechGearLab and "Best for Strong Suction" by PCmag. That's quite an endorsement, especially coming from such high-quality sources.

Out of the sources that tested and rated both of these Robot Vacuums, Modern Castle preferred the Roborock S4, whereas reviewers at Smart Robot Reviews, Pocket-lint, and The Ambient liked the Roborock S5/S5x better. TechHive gave them identical review scores.

We also took a look at which sources liked these products best - the highest Roborock S4 rating came from Modern Castle, whereas the Roborock S5/S5x most impressed reviewers at Smart Robot Reviews; they earned scores of 9.6 and 10, respectively.

Lastly, we averaged out all of the reviews scores that we could find on these two products and compared them to other Robot Vacuums on the market. We learned that both of them performed far better than most of their competitors - the overall review average earned by Robot Vacuums being 7.2 out of 10, whereas the Roborock S4 and Roborock S5/S5x managed averages of 8.7 and 8.2 points, respectively.

Due to the difference in their prices, however, it's important to keep in mind that a direct Roborock S4 vs. Roborock S5/S5x 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.
