Choosing between these two flagship robot vacuums isn’t just about specs; it’s about how intelligently and consistently they clean in real homes. One focuses on extreme raw power and advanced AI recognition, while the other delivers a polished, fully automated cleaning experience. If you want deeper cleaning vs effortless maintenance, this comparison makes the difference clear.

Major Features:

Design and Cleaning System

Xiaomi Robot Vacuum 6 Max

Xiaomi takes an aggressive, next-gen approach with triple robotic arms and a simultaneous mop–scrape–wash system. The 16-hole water system ensures continuous mop cleaning, which helps maintain consistent results across larger areas. It’s designed to actively “work” on dirt rather than just glide over surfaces.

Roborock S9 MaxV Ultra

Roborock focuses on refinement with VibraRise 4.0 and sonic scrubbing at 4,000 vibrations per minute. The auto-lifting mop intelligently avoids carpets, while hot water washing ensures better hygiene. The system feels more optimized for real homes rather than experimental hardware.

Verdict

Xiaomi is more aggressive and innovative, but Roborock feels more refined and reliable in daily use.

Suction Power and Cleaning Performance

Xiaomi Robot Vacuum 6 Max

With a massive 35,000Pa suction and hair-cutting brush system, Xiaomi clearly targets deep cleaning, especially in homes with pets or heavy debris. It’s built to handle tougher dirt scenarios without clogging.

Roborock S9 MaxV Ultra

Roborock’s 22,000Pa suction is lower on paper, but paired with sonic mopping, it delivers more precise cleaning. It’s less about brute force and more about balanced efficiency.

Verdict

Xiaomi wins on raw cleaning power, but Roborock offers a more balanced and controlled cleaning experience.

Navigation and AI Intelligence

Xiaomi Robot Vacuum 6 Max

The AI system recognizes 280 object types and 47 dirt categories using a triple-camera setup. This allows highly adaptive cleaning, especially in cluttered spaces.

Roborock S9 MaxV Ultra

Roborock combines Reactive AI 3.0 with LiDAR, structured light, and RGB cameras. This hybrid approach improves accuracy, especially in low-light and complex layouts.

Verdict

Xiaomi is more ambitious with AI, but Roborock is more consistent and dependable.

Smart Features and Automation

Xiaomi Robot Vacuum 6 Max

It includes Mi Home app control, Xiao Ai voice assistant, and unique features like pet monitoring and video calls. However, it lacks a fully automated dock system.

Roborock S9 MaxV Ultra

Roborock dominates here with RockDock Ultra 2.0, offering self-washing, drying, detergent dispensing, and auto-refill. It also supports Alexa, Siri, Google Home, and Matter 2.0.

Verdict

Roborock clearly wins with a near hands-free experience.

Hardware and Real-World Usage

Xiaomi Robot Vacuum 6 Max

With 6 cm obstacle crossing and triple-arm hardware, it’s better suited for uneven surfaces and challenging layouts. It’s built for physical adaptability.

Roborock S9 MaxV Ultra

Roborock focuses on convenience, faster charging, off-peak scheduling, and minimal manual intervention thanks to its advanced dock.

Verdict

Xiaomi handles tough environments better, but Roborock is far easier to live with daily.

Pricing and Value

Xiaomi Robot Vacuum 6 Max

Priced at ¥4,899 (~$680), it delivers flagship-level features at a much lower cost, making it highly value-focused.

Roborock S9 MaxV Ultra

At ≈ ¥11,700 (~$1,630), it’s significantly more expensive but justifies it with premium automation and convenience.

Verdict

Xiaomi is the better value pick, while Roborock is a premium, convenience-first investment.

Final Verdict

Xiaomi Robot Vacuum 6 Max is built for power users who want maximum suction, advanced AI recognition, and aggressive cleaning performance at a lower price. But the Roborock S9 MaxV Ultra delivers a more complete experience, with smarter automation, better mopping precision, and almost zero maintenance. 

If you want cleaning power at an affordable price, then choose Xiaomi; if effortless daily use matters more, Roborock is the smarter but pricier choice.
