roborock S8 Pro Ultra Robot Vacuum and Mop, Auto Drying, Auto Mop Washing, Self Emptying, Self Refilling, Liftable Dual Brush Sonic Mop, 6000Pa Suction, Obstacle Avoidance(RockDock Ultra Series) Roborock robot vacuum only supports 2.4G WiFi. However, since most routers support both 2.4G and 5G, to ensure the machine's stability, it is recommended to switch to 2.4G WiFi when using the robot by following the instructions of your router setup. Forget About Cleaning, Really. With Roborock?s all-in-one docking system, S8 Pro Ultra can automatically complete the mop washing and drying process, preventing unpleasant odors. Auto self-emptying with a large dust bag allows holding for up to 7 weeks of dust. The dock even cleans itself and refills the robot water tank for you, extending its mopping range to up to 3230 sqft (300 sqm). Just set it and forget it. Double Brushes, Double Cleaning. Roborock?s newest dual rubber brush system provides a cleaner effect in one go and fewer hair tangles. The more powerful 6000Pa suction drives the robot vacuum to pick up debris, hair, dust, and more from hard floors and carpets more quickly. You can even choose different suction modes in the app based on the degree of dirt, with the highest mode being Max+. Upgraded VibraRise 2.0 Mopping System. The VibraRise 2.0 improves its vibration module from 1 area to 2 areas, providing a wider mopping zone, up to 3000 times/min high-speed scrubbing, and over 6N consistent mopping pressure, stains from soda to dried-on spills and more can be cleaned deeply and more effectively. You can choose different water flows in the app based on the floor material to achieve better mopping effects. For areas with stubborn stains, it is recommended to use the High mode. Liftable Brushes and Mop Offer You More. The liftable brushes and mop can separate vacuuming and mopping in a single clean, maximizes the cleaning effectiveness for different tasks such as carpets cleaning and hard floor cleaning, and avoids leaving stains after a clean. If an entrapping threshold is set in the app, the brushes and mop will both lift automatically and help the robot climb it more easily. Reactive 3D Obstacle Avoidance. With 3D structured light and infrared image technology, Roborock S8 Pro Ultra is smart enough to identify unknown objects on the floor, determine their size and location, and bypass them in both bright and dark environments. Paired with LiDAR navigation and 3D mapping, detailed maps are generated for more accurate and customized cleaning. *Only support 2.4G WiFi.
