TL;DR
Roborock unveiled the Saros 20 and Saros 20 Sonic at CES 2026 with an upgraded AdaptiLift Chassis 3.0 that lets the robots scale thresholds up to 3.3 inches. The Sonic model adds a VibraRise 5.0 sonic mop that reaches baseboards and offers app-controlled water flow and vibration.
What happened
At CES 2026 Roborock introduced two new flagship robot vacuums, the Saros 20 and Saros 20 Sonic, featuring an improved AdaptiLift Chassis 3.0. The refreshed chassis enables the robots to surmount thresholds up to 3.3 inches in total height, including handling double-layer thresholds with individual step heights of about 1.7 and 1.57 inches. The chassis also uses dynamic elevation to raise the vacuum for more effective cleaning on carpet with pile as tall as 1.2 inches, and the adjustable height can help the machines free themselves when they encounter obstacles. The Sonic variant incorporates an updated VibraRise 5.0 sonic mop that extends to clean close to baseboards; users can tailor water output and mop vibration from Roborock’s app. Both models are slated to arrive later this year; Roborock has not disclosed pricing.
Why it matters
- Higher threshold clearance means fewer manual interventions when robots encounter doorways and raised transitions.
- Adjustable chassis elevation can improve cleaning on thicker carpets that prior models might struggle with.
- A mop that reaches baseboards could reduce the need for follow-up manual mopping along edges.
- App-controlled mop settings let users tune cleaning for different floor types without hardware changes.

Quick glossary
- AdaptiLift Chassis: A movable robot vacuum chassis that can raise or lower the machine to handle obstacles and adjust to different floor heights.
- Carpet pile: The height or thickness of the carpet fibers; higher pile indicates thicker, longer fibers.
- Sonic mop: A mopping system that uses high-frequency vibrations to loosen dirt and improve cleaning performance.
- Threshold: A raised strip at a doorway or room transition that can impede small-wheeled devices.
- CES: An annual trade show (Consumer Electronics Show) where companies often announce new consumer technology products.
