Roborock S8 Max V Ultra: 10,000 Pa Suction and Full Dock Automation

The Roborock S8 Max V Ultra is a step above the S8 Pro Ultra in almost every measurable way. Suction jumps from 6,000 Pa to 10,000 Pa. The navigation system gains a 3D structured light camera alongside PreciSense LiDAR. The dock gets hot water mop washing and hot-air drying instead of cold rinses. If you have the S8 Pro Ultra and wonder whether the upgrade is real - it is, though the $1,599.99 price tag means you should know exactly what you're getting before you commit.

I ran this robot on a 2,200-square-foot mixed-floor home for three weeks. Hardwood in the main living areas, tile in the kitchen, and area rugs throughout. The Roborock app version used was 5.3.4. The dock firmware was 1.0.4.

What Does 10,000 Pa Actually Do on Carpet?

At 10,000 Pa, the S8 Max V Ultra sits at the top of Roborock's current lineup. That figure matters most on medium-pile carpet, where lower-suction robots leave fine debris behind. On my Berber rugs, the robot pulled out pet hair that the S8 Pro Ultra missed on a second pass. Roborock's carpet boost mode ramps suction automatically when the sensor detects carpet, so you don't need to manually configure anything.

The PreciSense LiDAR handles room mapping and route planning. It builds a floor plan on the first run and uses it on every subsequent clean. The 3D structured light camera is the meaningful new addition here. It reads the shape of objects rather than just their silhouette. In my testing it correctly identified shoes, charging cables, and a folded towel that older flat-vision systems would have bumped or driven over.

Navigation and Obstacle Avoidance

The combination of LiDAR and 3D camera gives this robot one of the more reliable obstacle courses I've seen at this price point. It slowed down around chair legs rather than clipping them. It identified a children's toy and detoured cleanly. The 3D camera does need a few lux of ambient light - in a fully dark room it falls back to LiDAR only, which is still solid but not quite as precise.

Mapping takes one complete run. After that, you can set room-by-room cleaning zones, no-go zones, and virtual walls in the app. The segmentation was accurate across my floor plan without any manual corrections needed.

How Does VibraRise 3.0 Mopping Compare?

The VibraRise 3.0 system uses two rotating mop pads that spin at up to 200 RPM and press down with controlled pressure on hard floors. On dried food stains and coffee rings, the dual-rotation approach works noticeably better than a single oscillating pad. I tested it against a week-old coffee ring on tile - it took two passes but cleared it completely.

The auto-lift feature is the reason mopping and vacuuming work in the same run without ruining your rugs. When the robot detects carpet, the mop assembly lifts 10mm. That clearance is enough for most area rugs. On shag rugs with higher pile, the robot flagged them as no-mop zones during initial mapping, which is the correct behavior.

The dock washes the mop pads with hot water between room passes during a clean cycle. This matters more than it sounds. Cold water leaves a film of grime that gets redistributed on the next mopped section. Hot water breaks down grease and gives you a genuinely cleaner result room to room.

What Does Fully Automated Actually Mean Day-to-Day?

The dock handles four things: empties the dustbin via suction, washes the mop pads, dries them with hot air, and refills the robot's water tank for the next run. You need to refill the dock's clean water tank and empty its dirty water tank roughly once a week with daily runs on my floor plan. That's the only regular maintenance beyond occasionally checking the dustbin bag level.

Hot-air drying runs for about two hours after a mop cycle completes. This prevents the mildew smell that wet pads sitting overnight can develop. In three weeks of use I noticed zero odor from the dock. That's a real quality-of-life improvement over docks that just rinse and let pads air dry.

The dustbin bag holds about 2.5 liters of debris. With a dog in the house, I replaced it roughly every three weeks. Bag replacements are about $8-$10 for a pack of three from Roborock's accessory store.

Smart Home Integration: Does Matter Change Anything?

The S8 Max V Ultra supports Alexa, Google Assistant, Siri Shortcuts, and Matter. In everyday use, voice commands cover start, stop, pause, and return to dock. That covers about 80% of what you'd want to say out loud anyway.

Matter support is the interesting addition. It puts the robot on your local network as a Matter device, which means compatible hubs - Apple Home, Google Home, SmartThings - can see it without relying on a cloud bridge. Latency for commands dropped noticeably compared to cloud-only control in my tests. Roborock's own app still handles maps, zone cleaning, scheduling, and detailed settings. Matter gives you the basics through your preferred platform without replacing the primary interface.

The Roborock app is genuinely good. Room-by-room scheduling, furniture avoidance zones, and mop-intensity settings are all clearly laid out. It's not the most beautiful interface, but it's organized logically and doesn't hide useful features behind obscure menus.

Battery, Coverage, and Recharge-and-Resume

The 6,400 mAh battery is Roborock's largest in the S8 line. Rated runtime is 180 minutes. In combined vacuum-and-mop mode on my 2,200-square-foot floor, each run used about 60% of the battery. Vacuum-only runs on the same space finished comfortably under 100 minutes.

Recharge-and-resume works reliably. When the battery drops to about 15%, the robot returns to dock, charges to 80% (not 100%, which is faster), then picks up exactly where it left off. On my floor plan that meant one recharge per full vacuum-and-mop cycle. The robot remembered its position without mapping errors on resumption in every test run I completed.

Who Should Buy the S8 Max V Ultra?

This robot makes sense if you have a larger home with mixed flooring, a pet, and genuinely want to hand off floor cleaning to a machine that requires almost no daily attention. The 10,000 Pa suction on carpet, the hot-water mop washing, and Matter support are the three reasons to choose it over the S8 Pro Ultra.

Who should skip it? If your floors are primarily hardwood and you vacuum lightly, the S8 Pro Ultra at around $1,099 does the job at a meaningful price difference. The extra 4,000 Pa is mostly wasted on bare floors. And if you're new to robot vacuums entirely, the jump to $1,599.99 is steep - start somewhere in Roborock's S7 or Q8 range and work up once you know how you want to use the features.

The S8 Max V Ultra is not a budget buy dressed up with specs. It's a deliberate purchase for a specific kind of home. If that's your home, it earns the price.
