iLife A4s vs Roborock S4

Analysis:

The iLife A4s is an example of a great Robot Vacuum at its $190 budget.

In the case of the Roborock S4, however, we weren't able to find enough data to come to any reliable conclusions.

The iLife A4s was loved by reviewers at PCmag, a highly trusted source that performs reliable in-depth testing. It did great in its "The Best Robot Vacuums for 2020" roundup where it was named its "Best for Budget-Friendly Vacuuming", which, in itself, makes it a product worth considering.

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 "Upgrade pick" in its "The Best Robot Vacuums" 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 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 iLife A4s managed to earn a rating of 9.1 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 iLife A4s 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 iLife A4s 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.
