iRobot Roomba 980 vs Dser RoboGeek 20T & 21T

The iRobot Roomba 980 is a great Robot Vacuum for its $545 asking price.

The Dser RoboGeek 21T, however, while a reasonable product for $155, doesn't stack up against its competitors quite as well. If you're considering Robot Vacuums in the $150 range, you might want to check out some better options.

While the iRobot Roomba 980 wasn't able to make it to the very top of any roundups from sources that perform quality hands-on testing, it still got featured in a large number of them. Android Central, TechGearLab, goodgearguide.com.au, Modern Castle, Techradar, CNET, Tech Advisor, PCmag, Tom's Guide, inews.co.uk, The Independent, and Smart Robot Reviews have all deemed it worthy of a place on their respective shortlists.

Moving on to the Dser RoboGeek 21T: no sources that perform reliable and objective hands-on testing have included it in their Robot Vacuum roundups, which usually means that a product doesn't make for a good purchase.

We couldn't find any sources that tested both of these Robot Vacuums, so we only analyzed how they performed in reviews from different sites.

We first examined which sources rated each of these best and found that the iRobot Roomba 980 got its highest, 10, rating from Gadget Review, while the Dser RoboGeek 21T earned its best, 7, score from KnowTechie.

Lastly, we averaged out all of their review ratings and observed that the iRobot Roomba 980, with its 8.3 average, performed considerably better than most Robot Vacuums - the mean score for the product category being 7.2 out of 10 - while the Dser RoboGeek 21T managed an average of 7.0.

There's one caveat here - it might not be entirely justifiable to do a direct iRobot Roomba 980 vs. Dser RoboGeek 21T review average comparison since they aren't priced the same and more expensive products tend to get higher review scores from some sources.
