What you can expect from the Roborock Saros 20
What testers say about the Roborock Saros 20
The Roborock Saros 20 is a flagship with an embedded lidar and no turret, keeping it under 3.1 inches tall, a lifting chassis that carries the robot over thresholds of more than 1.6 inches and adapts to thick carpet, two spinning mop pads that detach automatically, and a station that washes in boiling-hot water, dries with hot air and doses detergent. TechRadar names it the best robot for carpet, Tom's Guide the best for pet hair, and Vacuum Wars ranks it 11th of 20.
All three testers see the same strength: embedded pet hair and sand in carpet. Tom's Guide measured the effect of the 36,000 Pa of suction, the highest in their guide, and saw the twin anti-tangle brush stay clean even after heavy runs; Vacuum Wars lifted 89 percent of the sand out of carpet and 88 percent of the pressed-in pet hair, with a perfect score in the long-hair test. Obstacle recognition dodged toys and bowls reliably, and the low build takes it under furniture a turret cannot. The pads press with adaptive force and use less water than average, which limits streaks.
The criticism targets mopping and price: Tom's Guide saw patches missed and visible streaks in the lab, TechRadar still finds sticky spills a job for a cloth, and both call it more machine than many homes need, at a price to match. TechRadar also saw the odd strange behavior on certain tasks. For homes with plenty of carpet, thick rugs, high thresholds and shedding pets it is one of the best choices; if mopping is the priority, look at a roller-mop model.
