iRobot Roomba 675 vs Roborock S4

Analysis:

Two highly trusted sources that perform well-thought-out in-depth testing consider the iRobot Roomba 675 to be a great product - it earned the "Top Pick" title from Wirecutter (NYTimes) and "Best for Most Affordable Roomba With Wi-Fi" from PCmag in their respective Robot Vacuum roundups, which is a good indication of it being a notable product.

Returning to the Roborock S4, Wirecutter (NYTimes), a source that's known for its high-quality in-depth testing, has great things to say about it. In fact, it was named its "Also great" in its "The Best Vacuum Cleaners" roundup, which is quite a feat.

We conducted an analysis of all of the review data that we could find on these two products. First, we focused on sources that tested and rated both of them, like Modern Castle and Smart Robot Reviews, and learned that they all showed a preference for the Roborock S4.

Then we took a look at the highest review scores that these two Robot Vacuums received. We found that the iRobot Roomba 675 managed to earn a rating of 9.4 from Modern Castle, whereas the Roborock S4 got its highest, 9.6, score from reviewers at 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 iRobot Roomba 675 and Roborock S4 managed averages of 8.4 and 8.7 points, respectively.

Due to the difference in their prices, however, it's important to keep in mind that a direct iRobot Roomba 675 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.
