Roborock E4 vs iLife A4s

Analysis:

The Roborock E4 is a great Robot Vacuum for its $269 asking price.

The iLife A4s, however, while a reasonable product for $119, doesn't stack up against its competitors quite as well. If you're considering Robot Vacuums in the $200 range, you might want to check out some better options.

The Roborock E4 has managed to impress reviewers from some of the most highly trusted sources on the internet, including Rtings and TechGearLab. It performed great in their in-depth hands-on roundups - it was awarded the "Best Budget" title by Android Central and "Best Budget Robot Vacuum Cleaner For Bare Floors" by Rtings in their respective Robot Vacuum roundups. That's high praise, especially when coming from such high-quality sources.

As for the iLife A4s, it was really well-received by reviewers at reviewgeek.com, a reliable source that's known for conducting its own, high-quality, in-depth testing. It performed great in its "The 6 Best Robot Vacuums" roundup and was named its "Best Budget Option", which, on its own, makes it a product that warrants a closer look.

When we thoroughly analyzed their review scores, we learned that all of the sources that tested both Robot Vacuums, including Modern Castle and TechGearLab, preferred the Roborock E4 over the iLife A4s.

We also took a look at which sources they managed to impress the most. The Roborock E4 was liked best by Modern Castle, which gave it a score of 9.6, while the iLife A4s got its highest, 9.1, score 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 Roborock E4 and iLife A4s managed averages of 9.3 and 8.0 points, respectively.

Due to the difference in their prices, however, it's important to keep in mind that a direct Roborock E4 vs. iLife A4s 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.
