Roborock S10 MaxV Ultra Steam: Robot Vacuum With 110°C Steam

Roborock has a new flagship. On October 12, the company officially launched the S10 MaxV Ultra Steam in South Korea, a robot vacuum and mop built around one of the hottest technologies in the 2026 cleaning market: high-temperature steam.

The headline numbers are aggressive: up to 110°C (230°F) steam cleaning for the mopping system and 36,000 Pa of suction power. According to the company, the new model was developed with the cleaning and hygiene standards of Korean consumers in mind, and it automates not just vacuuming and mopping, but also the maintenance of the mop and dock after the job is done.

What’s new in the S10 MaxV Ultra Steam

110°C steam for mopping hygiene

The centerpiece of the new model is its hygiene management system. The mop is first cleaned with hot water at up to 100°C, then treated with steam at 110°C to lift and remove dirt. After a cleaning session, hot air at 63°C dries both the mop and the dust discharge path, while the dock itself is self-cleaned with 100°C hot water.

The mopping hardware gets Roborock’s VibraRise 5.0 system, which applies 14N of downward pressure with ultrasonic vibrations of up to 4,000 times per minute to scrub out floor contaminants. An expandable mop head reaches along walls and into corners — areas where round robot vacuums have traditionally struggled.

36,000 Pa suction and an anti-tangle system

On the vacuum side, the S10 MaxV Ultra Steam delivers up to 36,000 Pa of suction, putting it at the very top of the 2026 market alongside other flagship models. It is paired with an anti-tangle system designed to minimize hair wrapping, with Roborock claiming it can handle hair up to 40 cm in length without tangling — welcome news for pet owners and long-haired households.

AdaptLift Chassis 3.0 and Reactive AI 3.0

Driving performance gets a notable upgrade. The AdaptLift Chassis 3.0 can climb dual thresholds of up to 8.8 cm, while the robot’s height has been reduced to just 7.95 cm so it can slide under more furniture. For navigation, Reactive AI 3.0 uses triple structured light combined with an RGB camera to recognize over 300 types of objects — the kind of obstacle avoidance that lets a robot tell the difference between a charging cable and a pet accident.

Background: the industry’s pivot to steam

The S10 MaxV Ultra Steam did not arrive in a vacuum (pun intended). Steam has become Roborock’s signature battleground this fall. On October 8, the company’s F25 Ultra Steam Gen 2 stick-style floor washer launched at $699.99 (down from $799.99), built around VaporFlow 2.0 steam at 356°F and 187°F hot-water washing. Now the same hygiene-first philosophy has landed on its flagship robot line.

The suction numbers tell another story about how fast the top end has moved. Roborock’s S8 MaxV Ultra, reviewed in 2024 at $1,800, topped out at 10,000 Pa. Two years later, 36,000 Pa is becoming the flagship standard: Roborock’s own Saros 20 Flow also lists 36,000 Pa, and Xiaomi’s new Robot Vacuum 6 Series advertises 35,000 Pa. With raw suction hitting diminishing returns, steam cleaning and self-maintenance have become the new differentiators — exactly the shift the Korean launch emphasizes, moving from a suction-power race to post-cleaning hygiene management and maintenance convenience.

Steam’s appeal is straightforward: hot water and vapor break down sticky stains and grease that room-temperature mopping leaves behind, while high temperatures help sanitize the mop itself. Roborock has been pushing this message across its lineup. The Saros 20 Flow, the company’s other 2026 flagship, already pairs 36,000 Pa of suction with a pressurized self-cleaning mop system promising a “spa-like finish” on hard floors, plus AdaptiLift hardware that crosses thresholds up to 3.46 inches — at a retail price of $1,699.99. The S10 MaxV Ultra Steam takes that self-maintenance story one step further by adding genuine steam at 110°C.

What it means: who it’s for, and what to watch

For buyers, the S10 MaxV Ultra Steam’s proposition is clear: a robot that not only cleans floors but also keeps its own mops and dock sanitary with minimal intervention. The 110°C steam system, combined with hot-air drying of the mop and dust path, targets the lingering problem of odor and bacteria in self-washing docks — one of the most common complaints about all-in-one stations.

There are still open questions. Roborock has not announced pricing or availability outside South Korea, and there is no word yet on when — or whether — the S10 MaxV Ultra Steam will reach North America or Europe. Roborock frequently launches first in Asia before expanding, so a wider rollout is plausible but unconfirmed. As always with launch claims, the real test will be independent reviews of the steam system’s effect on stubborn stains and the anti-tangle brush’s durability over time.

Competitors are unlikely to sit still. Xiaomi’s Robot Vacuum 6 Series, launched earlier this month, counters with 35,000 Pa of suction and a robotic-leg design for climbing, while Dreame, Ecovacs and Narwal have all spent 2026 trading blows on mop-washing temperatures and self-maintenance features. With Roborock now staking out 110°C steam as its flagship headline, the next round of flagship announcements may well be measured in degrees, not just Pascals.

Either way, the message from the 2026 flagship race is unmistakable: the future of robot vacuums is not just about how hard they suck, but about how cleanly they take care of themselves.
