Compared with the previous generation S6, the biggest change of S7 is the use of Sonic Mopping. The official said that the mop can vibrate at a frequency of 50Hz, which can vibrate 3000 times per minute, which can effectively mop the floor and remove dry stains. After cleaning, the mop can also lift itself 5 mm to prevent dirty streaks from appearing on the floor.
Another big improvement is the ultrasonic carpet recognition technology, which is equipped with a special carpet recognition sensor. When the sweeping robot touches the carpet, it will automatically lift the mop to prevent the carpet from getting wet.
In other respects, the Roborock S7 has a maximum suction power of 2500 Pa and uses lidar for navigation; the trash can has a capacity of 470 ml, and the water tank can hold up to 300 ml; the battery power is 5200mAh, which is the most in the “quiet” mode and low water flow mop settings. Can be used for 3 hours; all controls can be done through Roborock or Mi Home apps.
