As part of CES 2021, Roborock presented a new vacuum robot for the global market. The new Roborock S7 vacuum robot is based on last year's Roborock T7, which was intended exclusively for the Chinese market.
New features of the Roborock S7 include an improved "Sonic Mopping" function, carpet detection by ultrasound and a floating solid rubber main brush that catches dirt better and ensures more contact with the ground. More on this in the following article.
The Xiaomi vacuum robot was one of the hottest Xiaomi products this year. About a year after the release of the first model, the Roborock S5 series, which is traded with the Roborock S50 and S55 as the "Xiaomi Suction Robot Generation 2", is not directly attributable to the Xiaomi product line.
