This is the plumbed configuration of Roborock's flagship-class Saros 10: the same 22,000 Pa HyperForce® robot, paired with a RockDock® Ultra that connects directly to your home's water supply and drain. The dock refills its clean water automatically and sends dirty mop water down the drain, so you never carry tanks to a sink - Roborock quotes up to 7 weeks of hands-free operation across dust emptying, warm water tank refilling, 176 F hot water self-cleaning, and automatic detergent dispensing.
The robot itself is the slimmest in Roborock's flagship line: the RetractSense™ Navigation System lowers the LDS turret into the body for a 3.14-inch (7.98 cm) profile that fits under low sofas and beds. ReactiveAI 3.0 obstacle recognition combines front triple structured light, an RGB camera, and VertiBeam™ lateral structured light, while the VibraRise® 4.0 mopping system scrubs with dual sonic vibration zones at up to 8N of pressure. The DuoDivide™ main brush and FlexiArm™ Riser side brush keep hair from tangling either brush.
Choose this version if your laundry room, kitchen, or bathroom has a water line and drain within reach of the dock. If you would rather skip plumbing entirely, the same robot is sold as the Saros 10 with Dual Anti-tangle System, whose RockDock® Ultra 2.0 uses onboard tanks.
