iRobot Roomba e5 vs Tenergy Otis

Analysis:

The iRobot Roomba e5 (5150) is a great Robot Vacuum for its $299 asking price.

The Tenergy Otis, on the other hand, is not worth its $165 price tag and should be avoided by most people. We strongly suggest that you take a look at some better alternatives if you're considering spending around $150 on a Robot Vacuum.

The iRobot Roomba e5 (5150) was loved by reviewers at Wirecutter (NYTimes), a highly trusted source that performs reliable in-depth testing. It did great in its "The Best Vacuum Cleaners" roundup where it was named its "Also great", which, in itself, makes it a product worth considering.

As for the Tenergy Otis - Modern Castle, a source that conducts reliable hands-on testing, has featured it in its Tenergy Otis Review roundup. However, it didn't make it to any of the top spots.

When we thoroughly analyzed their review scores, we learned that all of the sources that tested both Robot Vacuums, including Modern Castle, preferred the iRobot Roomba e5 (5150) over the Tenergy Otis.

We also took a look at which sources they managed to impress the most. The iRobot Roomba e5 (5150) was liked best by Modern Castle, which gave it a score of 9.5, while the Tenergy Otis got its highest, 9.3, 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 iRobot Roomba e5 (5150) and Tenergy Otis managed averages of 8.2 and 9.3 points, respectively.

Due to the difference in their prices, however, it's important to keep in mind that a direct iRobot Roomba e5 (5150) vs. Tenergy Otis 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.
