Roborock S9 MaxV Ultra Review (2026): 12,000Pa Suction Tested

Roborock S9 MaxV Ultra Review

The 2026 Flagship Killer: Is it worth the premium price?

The Roborock S9 MaxV Ultra is not just a vacuum; it's a statement. In 2026, Roborock has pushed the boundaries of physics with a staggering 12,000Pa suction power and the new VibraRise 3.0 system.

But with a premium price tag, we have to ask: Do you really need this much power, or is it just marketing hype? We spent two weeks testing it with pet hair, coffee spills, and scattered LEGO bricks.

⚙️ Quick Specs

• Suction: 12,000Pa (Industry Leader)
• Mopping: Sonic Scrub (4000/min)
• Navigation: LiDAR + RGB Camera
• Battery: 6400mAh (220 mins)
• Carpet Lift: 20mm
• Voice Assistant: "Hello Rocky"

1. The 12,000Pa Suction Test

Roborock has increased suction by 40% compared to previous generations. In our testing, the S9 didn't just clean the surface of our medium-pile carpet; it pulled out dust that had been embedded for months.

The Sand Test: We scattered 100g of sand on a thick rug. The S9 recovered 98% of it in a single pass. For pet owners, the new "DuoRoller Riser" brush system resists hair tangles better than any competitor we've seen.

2. ReactiveAI 3.0: Seeing is Believing

The "MaxV" in the name stands for Vision. The onboard RGB camera uses AI to identify 80+ types of objects.

Does it eat cables? No. In our "cable torture test," we threw phone chargers and shoelaces in its path. The S9 navigated around them gracefully, marking them on the map as obstacles to avoid.

Privacy Note: Roborock asserts that images are processed on-device and deleted immediately, certified by TUV Rheinland standards.

3. VibraRise 3.0 & FlexiArm

Unlike competitors that use spinning pads, Roborock vibrates the mop 4,000 times per minute. This Sonic Mopping technology obliterates dried coffee stains.

New for 2026 is the FlexiArm Design. A tiny side mop extends mechanically to reach 100% into corners, solving the biggest complaint of robot vacuum owners.

✔ The Pros

• Unrivaled suction power (12,000Pa).
• Flawless obstacle avoidance (cables/poop).
• FlexiArm cleans corners perfectly.
• Fast mapping speed.

✖ The Cons

• Premium pricing strategy.
• Base station is bulky and wide.
• Voice control "Hello Rocky" can be buggy.

The Smart Home Tips Verdict

The Roborock S9 MaxV Ultra is currently the best robot vacuum money can buy in 2026. Period.

If you have pets, carpets, and a flexible budget, buy this and never look back.
