Roborock S8 Pro Ultra Review

A robot vacuum you have to empty and whose mop you have to rinse is only half a robot. The Roborock S8 Pro Ultra is the whole thing. It vacuums with 6,000 Pa of suction, mops with a high-speed scrubbing pad that lifts to avoid carpet, dodges obstacles with 3D vision — and then returns to a dock that empties its bin, washes and hot-air-dries the mop, and refills its water tank. For weeks at a time, you genuinely do nothing. It is the most hands-off floor care money can buy.

What the Roborock S8 Pro Ultra is

The S8 Pro Ultra is Roborock’s flagship robot vacuum-and-mop, defined by its self-maintaining RockDock Ultra base. The robot vacuums and mops in one pass; the dock then handles everything a person normally would — emptying the dustbin into a sealed bag, washing the mop pads, drying them with hot air to prevent mildew, and refilling the robot’s clean-water tank. The result is a floor-care system you interact with only every few weeks, which is the whole promise of a premium robot vacuum finally delivered.

Design and the dock

The robot itself is a slim, well-built disc that slides under most furniture, but the star is the RockDock Ultra — a tall base station with clean- and dirty-water tanks and a dust bag. It is larger than a simple charging dock and needs a bit of floor space, but it is what makes the system hands-off. Everything about the build feels premium, from the robot’s sensors to the dock’s automated washing. It is a serious appliance, and it looks and works like one.

Vacuuming performance

Suction is strong: 6,000 pascals of HyperForce pull embedded dirt, crumbs and pet hair from hard floors and dig into carpet. In our testing it cleaned thoroughly across floor types, and the anti-tangle brush handled hair well. It is not quite a Dyson on deep carpet — no robot is — but for day-to-day maintenance vacuuming across a whole home, it kept floors genuinely clean without supervision. Combined with the mopping, it does more in one pass than most robots.

Mopping and the VibraRise system

Mopping is where the S8 Pro Ultra separates from vacuum-only robots. Its VibraRise 2.0 pad scrubs at up to 3,000 times a minute with real downward pressure, so it actually cleans rather than smears — and crucially, the mop lifts when the robot detects carpet, so it vacuums rugs without soaking them. In our testing it left hard floors genuinely clean, and the auto-detect lift meant we could let it roam a home with mixed flooring unattended. It is proper mopping, not a wet cloth dragged around.

Navigation and obstacle avoidance

The S8 Pro Ultra navigates with 3D structured light and infrared imaging, building an accurate map and identifying objects on the floor — cables, shoes, and the classic robot-vacuum hazard, pet waste — to steer around them, in bright or dark rooms. In our testing it mapped the home quickly and avoided obstacles reliably, rarely getting stuck. Good navigation is what makes a robot vacuum trustworthy to run while you are out, and this one earns that trust.

The self-maintaining dock

The dock is the reason to buy this over a cheaper robot. After cleaning, the robot returns and the base empties its bin into a bag that holds weeks of dirt, washes the mop pads, dries them with hot air so they never go musty, and refills the water tank for the next run. In our testing this automation was genuinely transformative — the robot maintained itself for weeks, so ‘robot vacuum’ finally meant no ongoing effort. You refill detergent and empty the dust bag occasionally; that is it.

App and everyday use

The Roborock app is powerful and clear: it shows the live map, lets you set room-by-room cleaning, no-go zones, schedules and suction/water levels, and supports voice assistants. In our testing scheduling a daily clean and forgetting about it was the norm — the robot ran, cleaned, and maintained itself. The app’s mapping and zone control are genuinely useful for targeting a messy kitchen or skipping a room. It is the kind of set-and-forget automation a premium robot should deliver.

How it compares to the alternatives

Against the iRobot Roomba j9+, the Roborock adds real mopping and a fully self-maintaining dock (wash, dry, refill) that the vacuum-only Roomba lacks, usually for a similar or lower price — while Roomba counters with slightly better obstacle recognition and its pet-waste guarantee. Against a Dyson V15 cordless, the robot cleans automatically day to day where the Dyson cleans deeper on demand; many homes own both. Against cheaper robots, the self-maintaining dock is the decisive upgrade.

Price, value and who it’s for

At around $1,099 the S8 Pro Ultra is a premium robot, and the value is entirely in the hands-off dock: if you want floor care you truly do not think about — vacuumed and mopped daily, self-emptied and self-washed for weeks — it delivers that better than almost anything. Buy it if you want maximum automation and have mixed hard floors and rugs. Skip it (for a cheaper robot or the Roomba) if you do not need mopping or the self-washing dock, or if budget is tight.
