Vacuuming is not nearly enough to get rid of dry, stubborn dirt. The dirt has to be scraped of the floor. Roborock S7 uses innovative sound vibration technology that makes its wet cloth rub the surface 3000 times a minute, thus removing dirt and sucking it into the vacuum cleaner’s tank with the power of 2500 Pa. The washing cloth is supplied with liquid by 300 ml water tank and is equipped with a smart mechanism that lifts the washing system as the robot encounters a carpet, thus facilitating the movement of the device. S7 automatically recognizes floor and carpets, using ultrasound, and marks them accordingly in your home layout so that next time you can choose, which part of the room to clean. The robot is designed both for small apartments and spacious offices, since one charge ensures up to 3 hours of work and its water tank reserves are sufficient for cleaning a 200 square meter room.
