The best robot vacuums are the ones you barely have to think about, and the Roborock Saros 20 fits that description well. It’s why it’s one of our favorite robovac / mop hybrids, and thanks to Prime Day, you can get it on sale at Amazon and Roborock for $1,359.99 ($240 off), a new low price.
In her testing, our smart home reviewer Jennifer Pattison Tuohy said the Saros 20 was the first robot vacuum she truly trusted to clean every room without getting stuck. Its excellent obstacle avoidance and low-profile design help it navigate around clutter and slip under low furniture. What’s more, it’s also the first robot vacuum Tuohy tested that could climb the two-inch transition between her bedroom and bathroom and make it over her thick living room rug. It’s also pretty hands-off in other ways, with Matter compatibility that lets you control it with your voice via any major smart home platform when you don’t feel like reaching for the phone.
The Saros 20 is equally impressive when it comes to mopping. Instead of a roller mop, it uses a pair of spinning mop pads that do a better job scrubbing tile floors and cleaning along grout lines, while also extending further into edges and corners. It supports warm-water mopping, and the pads can automatically detach and reattach when needed, helping keep carpets dry. Plus, its dock automatically empties the dustbin, washes and dries the mop pads, and can go up to 65 days between dustbin changes.
And, of course, vacuuming performance is also top-notch. With 36,000Pa of suction, the Saros 20 excels on hard floors, picking up everything from dust to pet hair. Tuohy found that only our top overall robovac pick, the Matic, did a better job on hard surfaces, while the Saros 20’s DuoDivide brush is designed to resist hair tangles, reducing the amount of maintenance required.
