Our Verdict

Roborock S8+/S8

Shark PowerDetect RV2820ZE

The Roborock S8+/S8 performs better than the Shark PowerDetect RV2820ZE on almost every floor surface. The upgraded Shark dock has more capabilities than Roborock's dock, yet performance is still lacking in comparison to the Roborock vacuum. As well, the Roborock is much easier to maintain, and Roborock's control app is excellent, much better than the very basic SharkClean app.
