iLife A9 vs iLife A4s

Analysis:

The iLife A9 and iLife A4s make for good, if unremarkable, Robot Vacuums at their respective budgets.

With that said, while they both should serve reasonably well, you might want to look into other options at the $250 and $140 price points - it's likely that there are some better alternatives available.

If you want to learn more about the iLife A9 and the iLife A4s, however, we prepared a summary of the information that we have:

The iLife A9 was loved by reviewers at PCmag, a highly trusted source that performs reliable in-depth testing. It did great in its "The Best Cheap Robot Vacuums for 2020" roundup where it was named its "Best for Efficient Navigation", which, in itself, makes it a product worth considering.

Returning to the iLife A4s, PCmag, 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 "Best for Budget-Friendly Vacuuming" in its "The Best Robot Vacuums for 2020" roundup, which is quite a feat.

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, for example, preferred the iLife A9, while PCmag 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 iLife A9 got reviewed the highest by Modern Castle - it gave it a rating of 9.4, while the iLife A4s most impressed reviewers at Modern Castle, which gave it a score of 9.1.

Lastly, we averaged out all of their review ratings and observed that the iLife A9, with its 8.2 average, performed considerably better than most Robot Vacuums - the mean score for the product category being 7.2 out of 10 - while the iLife A4s managed an average of 7.1.

There's one caveat here - it might not be entirely justifiable to do a direct iLife A9 vs. iLife A4s review average comparison since they aren't priced the same and more expensive products tend to get higher review scores from some sources.
