iRobot Roomba s9+

From the jury's assessment

The Roomba s9+ sets new standards for robot vacuum cleaners. A new progressive 3D sensor scans the area ahead 25 times per second so that the cleaner reaches every corner with its specially designed rubber brushes. The robot uses the Imprint™ Smart Mapping technology to save the floor plan and to pick the most efficient route. On carpets it uses the Power Boost technology and increases its absorbency to reach all the dirt in the carpet fibers. The cleaning process can be controlled via iRobot app, Alexa, or Google Assistant. The robot takes care of the whole process itself and even empties itself automatically into its own waste box so that the user does not have to take care of vacuum cleaning for weeks.
