EcoVacs Deebot N79S vs Roborock S4

Analysis:

The EcoVacs Deebot N79S is one of the very best Robot Vacuums that one can get for around $150. The Roborock S4, however, while a very good choice at its $330 price point, falls just short of being remarkable.

The EcoVacs Deebot N79S has impressed reviewers from two sources that are among the most highly trusted on the internet, namely PCmag and TechGearLab. It did great in their objective hands-on roundups - it earned the "Best for Most Features for the Price" and "Best on a Tight Budget" awards from PCmag and TechGearLab, respectively. That's high praise from such reputable sources.

As for the Roborock S4, it was really well-received by reviewers at Wirecutter, a reliable source that's known for conducting its own, high-quality, in-depth testing. It performed great in its "The Best Vacuum Cleaners" roundup and was named its "Also great", which, on its own, makes it a product that warrants a closer look.

We examined all of the review data that we could find and first took a look at sources that reviewed both of them, like TechHive, and found that they haven't shown a preference for either product.

Then we checked which sources liked these two Robot Vacuums best and found that the EcoVacs Deebot N79S got its highest, 9, review score from reviewers at Smart Robot Reviews, whereas the Roborock S4 earned its best score of 9.6 from Modern Castle.

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 EcoVacs Deebot N79S and Roborock S4 managed averages of 7.5 and 8.7 points, respectively.

Due to the difference in their prices, however, it's important to keep in mind that a direct EcoVacs Deebot N79S vs. Roborock S4 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.
