Roborock Unveils Sleek New Robot Vacuum and Mopping System

Key Takeaways

The Roborock Saros 20 Sonic features a unique D-shaped mop pad that vibrates and applies downward pressure for effective cleaning.
An upgraded RockDock base automates maintenance, cleaning, and drying of the mop pad to prevent odors and mold.
The Saros 20 Sonic will launch alongside a sister model, the Saros 20, which uses a dual spinning mop pad system.

Innovative Design and Technology

The Roborock Saros 20 Sonic stands out at CES 2026 with its impressive new mopping system. Unlike traditional robovacs that utilize spinning discs or rollers, the Saros 20 Sonic employs a wide D-shaped mop pad that extends nearly edge-to-edge, allowing for expansive cleaning coverage. This distinctive design enables it to kick out to the side when detecting the edge of a room, ensuring no corners are missed—a feature not commonly found in other robotic vacuums with similar pad designs.

Equipped with its motor, the mop pad produces 4,000 sonic vibrations per minute while exerting 14N of downward pressure, a significant increase compared to previous models. This enhanced pressure helps eliminate stubborn, dried-on dirt effectively. Additionally, an automatic dispenser ensures the cleaning solution is evenly diluted, providing precise control over the mopping process—especially beneficial for households with delicate surfaces.

Smart Maintenance with RockDock Technology

The upgraded RockDock base boosts convenience by handling most maintenance tasks. It can clean the mop pad with steaming hot water (212F / 100C) to eradicate bacteria and grease, followed by drying it with hot air (131F / 55C), consequently minimizing the risk of mold and foul odors. Notably, the dock can also clean the mop pad independently while the Saros 20 Sonic vacuums, thus optimizing operational efficiency.

Alongside the Saros 20 Sonic, Roborock will introduce the Saros 20, which boasts a different navigation system and uses a dual spinning mop pad design. While similar in many aspects, these two models showcase distinct cleaning technologies tailored to various user preferences, particularly for handling thick carpets.

Alternative Options in the Lineup

In addition to the Saros series, Roborock has unveiled the Qrevo Curv 2 Flow, featuring a roller mop that continuously dispenses clean water, ensuring a more hygienic cleaning process. This model effectively eliminates dirt during cleaning, contrasting with conventional methods that only clean upon returning to the dock.

The self-cleaning cycle of the Qrevo Curv 2 Flow stands out, employing a thorough soaking and scrubbing technique to keep the roller clean. While the water temperature used for this cleaning process (167F / 75C) is not as high as the Saros 20 Sonic’s, it remains effective for breaking down grease.

Roborock plans to release the Saros 20 Sonic, Saros 20, and Qrevo Curv 2 Flow in international markets this year, with pricing details forthcoming. Consumers can expect the Qrevo Curv 2 Flow to be slightly more affordable than the flagship Saros models. With innovative designs and efficient cleaning technology, these new robot vacuums aim to enhance the home cleaning experience significantly.
