Xiaomi Robot Vacuum 6 Max vs. Roborock S9 MaxV Ultra: A Detailed Comparison

Choosing a premium robot vacuum is no longer solely about suction power. The Xiaomi Robot Vacuum 6 Max and the Roborock S9 MaxV Ultra both offer AI features, advanced mopping systems, and automatic functions, but they take distinctly different approaches. Xiaomi prioritizes raw cleaning performance with aggressive hardware and a lower price point, while Roborock focuses on automation, refined navigation, and a user-friendly experience for busy households.

Power and Cleaning Performance

The Xiaomi Robot Vacuum 6 Max boasts a suction power of 35,000Pa [Gizmochina], exceeding the Roborock S9 MaxV Ultra’s 22,000Pa [Gizmochina]. This higher suction makes the Xiaomi more effective at lifting thick dust, large debris, and firmly embedded dirt. Its cleaning system simultaneously mops, scrapes, and washes, resulting in a more aggressive cleaning action.

Roborock, however, emphasizes precision. The S9 MaxV Ultra combines vacuuming with sonic mopping, utilizing vibration technology reaching 4,000 vibrations per minute to scrub stains effectively [Gizmochina].

Navigation and AI Intelligence

Xiaomi equips the 6 Max with AI panoramic obstacle avoidance and the ability to recognize 280 objects and 47 types of dirt [Daily Kiran]. This extensive recognition capability allows the robot to adapt its cleaning approach based on its surroundings. It too features a triple-camera system for detailed visual identification.

The Roborock S9 MaxV Ultra utilizes Reactive AI 3.0 and LiDAR, considered more reliable for navigation, particularly in homes with complex layouts, narrow passages, or frequent activity [Gizmochina]. Roborock also employs RGB cameras and structured light for real-time environmental awareness, minimizing collisions and getting stuck.

Mopping Systems: Aggression vs. Precision

Xiaomi’s mopping system relies on continuous water circulation through a 16-hole system, providing consistent wet mopping during operation. Roborock excels in precision and automation with its VibraRise 4.0 technology, lifting the mop up to 18mm to seamlessly transition from hard floors to carpets without wetting them [Gizmochina].

The Roborock S9 MaxV Ultra’s RockDock Ultra 2.0 further enhances convenience by washing the mop with 80°C hot water, drying it with 60°C hot air, refilling water, adding detergent, and self-cleaning [Gizmochina], approaching a “zero maintenance” system. Xiaomi’s dock lacks this level of automation.

Brush Systems and Obstacle Handling

For homes with pets or long-haired individuals, the Xiaomi 6 Max is better equipped with a hair-cutting brush and anti-tangle systems on both the main and side brushes [Daily Kiran]. Xiaomi also features triple robotic arms and can climb obstacles up to 6cm, with a minimum clearance of 9.3cm for cleaning under furniture [Daily Kiran].

Smart Features and Ecosystem Integration

Roborock offers broader voice control compatibility, supporting Alexa, Siri, Google, and Matter 2.0 [Gizmochina], while Xiaomi primarily relies on Xiao Ai. Both models offer video features for remote monitoring, with Roborock adding Pet Snap and cruise functionalities.

Key Differences Summarized

• Xiaomi: Excels in suction power, hardware, and price.
• Roborock: Excels in navigation, dock automation, and smart home integration.
• Xiaomi: More suitable for heavy cleaning and hair-prone environments.
• Roborock: Better suited for busy homes with carpets, children, and pets.

Pricing

The Xiaomi Robot Vacuum 6 Max is priced at ¥4,899, while the Roborock S9 MaxV Ultra costs around ¥11,700 [Daily Kiran]. This price difference positions Xiaomi as a high-value option for those prioritizing cleaning performance and hardware, while the Roborock S9 MaxV Ultra offers a more comprehensive and automated experience for intensive daily use.
