Traditionally, robotic vacuum cleaners (and manual vacuum cleaners, for that matter) tend to have a difficult time cleaning thick carpets and rugs. High fibers, combined with upward suction, are a recipe for getting stuck. It’s a little ironic, because that’s exactly the type of floor that would really benefit from a full vacuum.

In two of its new releases, Saros 20 and Saros 20 Sonic, Roborock has found a solution. And cleverly, it uses a feature that was originally designed to solve a completely different type of problem.
Let me back up a little. Like several of last year’s best robot vacuums, the new Saros 20 robots have small feet that extend to help lift them over small steps or high room thresholds. They’re a little less flashy than the long stilts that appear on the Roborock Rover, but they serve a useful purpose.
In this version 3.0 of the ‘AdaptiLift’ feature, you can boost the Saros 20 on single steps up to 1.77 inches/4.5 cm high, or a double step with a total of 3.34 inches/8.5 cm.
The new Saros 20 robots feature version 3.0 of the AdaptiLift Chassis, and this iteration has one more trick up its sleeve. You can also raise the robot vacuum to one of eight different preset heights and keep it there, level, while you clean. That means that if you find your bedroom carpet too thick, it can float to the right height to clean it, without getting stuck in the fibers.
In the demo area, I watched the Saros 20 Sonic stop at the edge of a thick carpet and then meticulously rise to the right height to traverse it. When the floor changed to a deeper pile, it rose a little higher in response. The movements were smooth and precise, and the robot remained level throughout the cleaning portion of the process. Impressive stuff.
A little less impressive, in my opinion, was the climbing stairs part. Roborock says that version 3.0 of Adaptilift has added stability, to raise and lower the robot smoothly so as not to risk damaging it, but in the demo space it went up and down quite loudly.
In the robot’s defense, the steps were at the maximum height it can handle, and on the higher side than you might normally find in someone’s house.
I’m excited to see how they perform in practice; A full review will be done when I get my hands on one to test it properly.
