New powerful Roborock Saros 20 Sonic robot vacuum revealed

Roborock has unveiled the Saros 20 Sonic robot vacuum and mop at CES 2026. This new flagship model builds on the Saros 10 model, which launched at the same event in 2025, with several upgrades.

The Roborock Saros 20 Sonic is a particularly powerful model, with up to 35,000 Pa suction power, a significant increase on the 22,000 Pa suction of the 10R. It features the DuoDivide Main Brush and FlexiArm Arc Side Brush with anti-tangle designs. Like its predecessor, it has a vibrational mopping system, though this is said to offer 1.75x more pressure; there is 14N of downward pressure with 4,0000 vibrations/min. Plus, according to Roborock, the extendable mop delivers improved corner cleaning. Depending on the cleaning mode, the mops can be detached and the main brush lifted for optimized cleaning performance.

Another new feature with the Roborock Saros 20 Sonic is the AdaptiLift Chassis 3.0, which can lift the robot over a double-layer threshold measuring 4.5+4 cm (1.8+1.6 inches). It has the same slim 7.98 cm (~3.1 inch) body as its predecessor with a retractable LDS sensor, used for navigation. On top of this, it comes with an upgraded RockDock, which offers detached mop washing with 100°C (~212°F) hot water, dock self-cleaning and emptying of the robot’s onboard dustbin.

Roborock is expecting to release the Saros 20 Sonic robot vacuum and mop between April and June 2026. It will be available in black or white, with standalone and Refill and Drainage System options to choose between. While the company has yet to announce the pricing of its new model, as a guide, the Roborock Saros 10 robot vacuum and mop launched with a $1,599.99 RRP (curr. $1,299.99 at Amazon).
