Top 5 Reasons Why Roborock S9 MaxV Ultra Is the Best
The Roborock S9 MaxV Ultra stands out because of its perfect combination of 22,000Pa suction + 7.98cm lifting LDS + 9-in-1 all-in-one dock.
- 22,000Pa Industry-Leading Suction Power. The first robot vacuum to deliver an overwhelming 22,000Pa suction. DirTect AI detects floor dirt levels and automatically increases suction for dusty areas, smoothly switching to mopping mode when liquids are detected. Powerfully picks up everything from fine carpet dust to pet hair.
- 7.98cm Lifting LDS Eliminates Blind Spots. When low clearance is detected, the LDS sensor automatically lowers to clean under furniture as low as 8cm. RetractSense LDS maintains wide-angle vision even while lifted, ensuring obstacle avoidance performance isn't compromised. Cleans under beds, sofas, and storage units without missing a spot.
- 9-in-1 All-in-One Dock for Complete Automation. 80-degree hot water mop washing removes 99.99% of Staphylococcus aureus and E. coli (TUV Rheinland certified), 60-degree hot air drying prevents odors, 2.5L auto dust emptying, and 70-degree hot water auto-fill. A truly all-in-one system requiring minimal post-cleaning maintenance.
- Reactive AI 3.0 Recognizes 108 Object Types. Front triple structured light, RGB camera, and VertiBeam side sensors combine to minimize blind spots. Detects and naturally avoids floor cables, socks, and even pet waste. Accurately senses tilted furniture for collision-free cleaning.
- DuoDivide Triple Anti-Tangle System. DuoDivide main brush rotates bidirectionally to gather hair centrally for suction, FlexiArm arc side brush uses centrifugal force for tangle-free cleaning. Even the wheel brush automatically sheds dust, eliminating post-cleaning tangle frustration.
