Overview
- Roborock showed the Saros Rover prototype using wheel‑legs, AI, motion sensors and 3D spatial data to climb stairs and clean each step, perform small jumps and balance without toppling.
- Saros 20 and Saros 20 Sonic were announced with 35,000 Pa suction and an upgraded chassis that can cross single thresholds up to 1.77 inches, with the Sonic’s extendable sonic mop scrubbing edges at up to 4,000 vibrations per minute.
- Roborock’s Qrevo Curv 2 Flow adopts a roller mop that self‑cleans in real time and extends to edges, offers 20,000 Pa suction, and goes on sale Jan. 19 at $849 promotional pricing before rising to $999 on Feb. 1.
- Dreame presented the Cyber X dock concept that ferries existing robot vacuums up and down stairs using tank‑like treads, though it cannot clean steps during transit and has no announced release date.
- Commentators noted that legged designs increase mechanical complexity and potential repair risk, while Roborock also outlined near‑term floor‑care launches such as the F25 Ace Pro on Jan. 19 ($550 intro, $699 MSRP) and confirmed robot mowers for the US market.
