The reviewer concluded that the Roborock Saros 20 earned a high spot on their top 20 robot vacuum list, citing its strong mopping and capable vacuuming performance, along with the high-end automations expected at its price tier.
This review by Vacuum Wars covers the Roborock Saros 20 robot vacuum, testing its mopping, vacuuming, obstacle avoidance, and threshold climbing capabilities. It also examines the features of its base station and app controls. The review provides detailed test results and observations on its performance in various household scenarios.
The Roborock Saros 20 is a strong contender for a premium all-in-one robot vacuum due to its advanced cleaning capabilities. Its mopping performance significantly improved, achieving above-average stain removal in tests with a low water penalty. Vacuuming also excelled, removing 89% of embedded sand in deep clean tests and 88% of flattened pet hair, while the anti-tangle brush performed perfectly with 7-inch hair. However, its dustbin is on the smaller side, which might necessitate more frequent emptying for pet owners or homes with significant debris. If you need an advanced robot vacuum with superior mopping, effective vacuuming, and impressive threshold climbing, this model is highly recommended. If your primary concern is minimal dustbin interaction on very large floor plans or with excessive pet hair, consider adjusting settings or be prepared for more frequent manual emptying.

The Roborock Saros 20, a premium robot vacuum, was put through several tests by Vacuum Wars. Its dual mop system with adaptive pressure and an extending pad delivered above-average stain removal and a low water penalty. Vacuuming performance was strong on both hard floors and carpets, with high scores in deep carpet cleaning and pet hair removal, and a tangle-free brush. The robot also demonstrated above-average obstacle avoidance and record-breaking threshold climbing. The advanced RockDock base station, offering hot water mop washing and auto-emptying, along with the detailed Roborock app, were highlighted as pros. Navigation, battery efficiency, and airflow bench tests were found to be average, and the dust bin was noted as being on the smaller side.
