Our Verdict

Roborock S7

Roborock S8+/S8

The Roborock S8 is better than the Roborock S7. The S8 has a more powerful suction motor and a more effective twin roll cleaning head, resulting in much better pet hair pick-up. The S8 also features a separate front-facing optical sensor that allows it to spot, identify, and react to obstacles placed in its way. That said, the S7 uses the same mopping feature and is still a good way of getting a well-rounded robot vacuum for a more affordable price.
