Climbing artist: AdaptiLift Chassis 3.0
Was at Saros 10 (our TestWhile the previous Saros 20 models had a limit of approximately 4 cm in height (which was already a top value), the new Saros 20 models significantly surpass this limit. Both the Saros 20 and the Saros 20 Sonic are equipped with the new AdaptiLift Chassis 3.0.
The new mechanism, consisting of the main drive, auxiliary wheel, and climbing arm, overcomes double thresholds up to 8,5 cm (4,5 + 4 cm) and improves cleaning performance on carpets. Instead of just lifting the mops, the Saros 20 now lifts the entire chassis when driving onto high-pile carpets (up to 3 cm). The housing no longer scrapes against the carpet pile, which, according to Roborock, optimizes airflow for 30% better dust pickup.

Roborock Saros 20 Sonic as successor to the Saros 10
The Saros 10 scored well in our test with its retractable LiDAR tower, but had a slight weakness when mopping. The vibrating plate was rigid; a separate mini-mop on the side was needed for the edges.
With the new VibraRise 5.0, Roborock is doing away with the side-mounted auxiliary mop. Instead, the main mopping module now extends mechanically to clean flush against the baseboard. The vibration area has also been increased by 27%, the contact pressure increased 1,75 times (up to 14 N), and the vibration frequency boosted to 4.000 movements per minute (previous models often reached 3.000).

Like the Saros 10, the Saros 20 Sonic also uses LDS LiDAR technology, which retracts into the housing when used with low furniture. The overall height remains an ultra-slim 7,98 cm.
Roborock Saros 20 as successor to the Saros 10R
The Saros 10R, released in 2025, relied solely on camera-based navigation (StarSight) and rotating mops. The new Saros 20 continues this concept and addresses the navigation criticisms.
During testing of the 10R, it was noticed that very thin cables were occasionally missed. The new StarSight Autonomous System 2.0 is designed to remedy this. According to Roborock, the scanning frequency is 21 times higher than that of conventional lasers, enabling the AI to detect over 200 object types as small as 2 x 2 cm.
Lateral distance measurement with VertiBeam has been improved to navigate even closer to chair legs without touching them.
The mopping system with two rotating mops has been retained but refined. The contact pressure is now variable (8 N to 13 N). If the robot detects stubborn stains (StainTarget AI), it automatically increases the pressure and water volume. The FlexiArm extends one of the mops for edge cleaning.
Performance leap: 35.000 Pascal suction power
This is where the biggest leap occurs. While the difference between the Saros 10R (19.000 Pa) and the Saros 10 (22.000 Pa) was still noticeable, Roborock has made both 20 series models significantly more powerful. With 35.000 Pa HyperForce suction power, these devices take their place at the absolute top of the market.

In combination with the DuoDivide brush (which already worked excellently against hair tangling in the test of the predecessor), the cleaning performance on carpets should be noticeably better.
The station: Now it's time to cook
The RockDock has also received a significant upgrade. The water temperature for mop washing has been increased from 80°C (Saros 10 series) to 100°C, and the 55°C hot air drying now also dries the entire air duct.
For easier maintenance, the cleaning tray is now a single piece, which should simplify manual cleaning. The dust bag is designed to last up to 65 days.
Prices and availability
The new models are planned for the second quarter of 2026. The product page for the Saros 20 is already online. here. online.
Roborock has not yet announced prices, but given the performance improvements, they are likely to be slightly higher than the starting prices of the predecessors (€1.399 - €1.499).
