Editor's Note (2026): The Roborock Qrevo S and QV 35A were popular mid-range robot vacuums, but both models have become increasingly difficult to find. If you're shopping for a new Roborock today, newer Qrevo models typically offer better value and longer software support.
Instead of focusing solely on these older models, we recommend considering the latest Qrevo lineup and comparing them against Roborock's current flagship robots.

Verdict
If you can find either model at a substantial discount, the Qrevo S remains the stronger choice. However, most buyers should skip both models and purchase a newer Qrevo Curv, Qrevo Edge, or Saros robot instead.
