Welcome

Thank you for choosing a Roborock S4 robot vacuum.

This robot vacuum features a precision laser mapping system able to quickly and accurately create maps of your home. Adaptive routing algorithms then allow it to plan the most effective cleaning route for each room based on the shape of the room and the obstacles within. Suction is generated by a powerful fan and advanced airflow management. A floating main brush keeps close to the ground, flicking dust and hair into the suction flow for a more thorough clean.

Through the Roborock app, you can see a map of your home, the location of the robot, and its cleaning path in real-time, set cleaning schedules and specific cleaning areas, and more, for full remote control. When at home, you can also control your robot with your voice through a voice assistant.

Roborock S4 was designed to make your life simpler through technology.

Now you can step away from vacuuming and focus on spending time with the people you love. We hope you enjoy your robot.
