Our Verdict
Samsung POWERbot R7040
Roborock S4
The Roborock S4 is a better vacuum for use on bare floors while the Samsung POWERbot R7040 is a bit better on carpets, although it's still not good on that surface. The Roborock cleans up almost all debris on bare floors, it has a much better battery, the dirt compartment is bigger, and it has a better build quality. However, the Samsung is easier to maintain, and it has no recurring costs.
