At CES 2026, Roborock unveiled a concept of a robot vacuum with legs, but also its latest flagship, the Saros 20. The spiritual successor of the Saros 10R, Roborock is stepping up its game by building upon the technologies we've seen on its products over the past few years. Having launched back in April, this robot vacuum redefines what the company believes is its best. Over the past few months, I've been relentlessly testing Roborock's Saros 20 robot vacuum, and after relying on the company's handheld vacuum, the F25 Ace Pro, for a while, it's a nice change of pace to have a robot doing all the hard work, while I can just chill. Here's everything you need to know about the company's best robot vacuum, what's improved from the previous generation, and what Roborock still needs to do to offer the best experience possible to customers.
