Roborock S4 vs Eufy RoboVac 11S

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 Eufy RoboVac 11S, it managed to impress reviewers from some of the internet's most highly trusted sources, PCmag and Wirecutter (NYTimes). It performed great in their hands-on roundups - it was named "Best for Low-Clearance Furniture" by PCmag and "Budget pick" by Wirecutter (NYTimes). That's quite an achievement, especially coming from such high-quality sources.

To get a better idea of how they fare when compared directly to each other, we analyzed review scores of sources that tested both. Modern Castle and Smart Robot Reviews, for example, preferred the Roborock S4, while TechHive 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 Roborock S4 got reviewed the highest by Modern Castle - it gave it a rating of 9.6, while the Eufy RoboVac 11S most impressed reviewers at Modern Castle, which gave it a score of 9.4.

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 Eufy RoboVac 11S managed averages of 8.7 and 7.8 points, respectively.

Due to the difference in their prices, however, it's important to keep in mind that a direct Roborock S4 vs. Eufy RoboVac 11S 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.
