Our Verdict
Roborock S4
Roborock S6
The Roborock S6 is a better robot vacuum than the Roborock S4. The S6 cleans all surface types much better, especially because it can climb onto high-pile carpets, and it has a mopping feature, although we don't currently test for this. It also has slightly better maneuverability and build quality. That being said, the battery life of both vacuums is very similar, so if you don't have carpet in your home, the S4 could be a good alternative.
