The Saros 20 Flow is Roborock's ultra-slim robot vacuum and roller mop for mixed-floor homes with pets and tricky room transitions. It pairs 36,000 Pa HyperForce suction with a SpiraFlow 2.0 roller mop that is continuously rinsed with fresh water through 16 outlets while spinning at 240 RPM. Dual anti-tangle brushes and up to 3.5 in threshold crossing help it move between hard floors, rugs and carpeted rooms. The RockDock handles hot-water mop washing, warm-air drying, detergent dispensing, refilling and dust emptying, so the routine upkeep is mostly hands-off. Against rivals, it leans on very high suction and a self-refreshing roller instead of spinning pads, which suits sticky marks and pet hair but is a bigger investment than mid-range bots.

The Roborock Saros 20 Flow is an ultra-slim robot vacuum and roller mop for homes with hard floors, carpets and pets. It has 36,000 Pa HyperForce suction and a 10.6 in (270 mm) roller mop that rotates at 240 RPM. Its SpiraFlow 2.0 system feeds fresh water through 16 pressurized outlets while it mops. AI RGB recognition identifies the floor type and adjusts water flow, and on wood floors it optimizes water use to help reduce streaking.
The DuoDivide main brush and dual lifting side brushes are designed to resist hair wrapping. AdaptiLift Traverse 3.0 uses a climbing arm to cross double-layer thresholds up to 3.5 in (8.8 cm) combined. The robot is 3.54 in (8.98 cm) tall, and its LiDAR retracts so it can clean under furniture with at least that much clearance. The reversible side brush extends corner coverage, and the roller mop can clean within 0.4 in (10 mm) of an edge.
Carpet settings in the Roborock app let you choose how the robot treats rugs. It can boost suction with the roller mop lifted, or follow paths that avoid rugs to help keep them dry. The RockDock washes the mop with water up to 212°F (100°C), dries the mop and dock base with 145°F (63°C) warm air, dispenses detergent, refills the robot with warm water and empties dust automatically. Intelligent dirt detection can extend mop washing and add a mopping pass where dirt is heavier.
