The S8 MaxV Ultra adds the pieces the S8 Pro Ultra leaves out: an RGB camera with AI obstacle avoidance, hot water mop washing and hot air drying, auto detergent dispensing, and nearly double the suction. The S8 Pro Ultra keeps the same LiDAR navigation, dual rubber brushes, and self-emptying dock at a much lower cost, making it the practical pick for hard-floor homes with fewer obstacles. Go MaxV if pet hair, cluttered floors, and a truly hands-off dock matter most.
Same family, same shape, very different capability. Both of these Roborocks use vibrating mop pads, dual rubber main brushes, and LiDAR mapping, so the floor plan drawing and the basic cleaning approach feel nearly identical in the app. The split shows up in the hardware bolted around that shared foundation. One gets a camera, a light, hot water mop washing, and an extendable side brush. The other keeps things simpler and costs a lot less. So the real question isn't which one cleans your kitchen floor. It's how much automation and obstacle smarts your household actually needs.

The overall ratings land at 8.1 for the MaxV Ultra and 7.6 for the Pro Ultra, and most of that gap comes from one category. Features rate 8.6 versus 6.2, which is a wide spread driven by the camera, hot water washing, detergent dispensing, and dirt detection. Cleaning sits closer at 8.1 versus 7.8, and navigation at 7.9 versus 7.6. So the two clean similarly well. The MaxV Ultra simply does more around that cleaning.
Suction is the headline number: 10,000 Pa on the MaxV Ultra against 6,000 Pa on the Pro Ultra, backed on both by dual rubber brushes that resist hair tangles. Obstacle handling separates them next. The Pro Ultra relies on 3D structured light alone, whereas the MaxV Ultra layers an RGB camera, a light for dark rooms, and AI recognition on top of that same structured light, which helps around cords, shoes, and pet messes. Dock behavior differs too. The MaxV Ultra washes its mop pad at 140°F, dries at 140°F, and doses detergent automatically for cleaner pads. And the mop lifts 20 mm on the MaxV Ultra versus 5 mm on the Pro Ultra, which matters on thicker rugs.
The MaxV Ultra pulls 10,000 Pa against the Pro Ultra's 6,000 Pa and adds an extendable side brush that reaches into corners the body can't. The Pro Ultra counters with a larger onboard dustbin, so it goes further between dock trips on big open floors.
Both use vibrating mop pads, but the MaxV Ultra vibrates at 4,000 per minute versus 3,000, adds a rotating edge mop for baseboards, offers four moisture levels instead of three, and lifts the pad 20 mm rather than 5 mm to keep carpets dry. The Pro Ultra applies 6 N of downward mop pressure and carries a larger onboard water tank for longer mopping runs between refills.
Higher suction at 10,000 Pa plus smart dirt detection lets the MaxV Ultra recognize heavily soiled spots and go back over them, which helps in shedding season. Both share the same dual rubber brush design that handles long hair without wrapping.
LiDAR mapping and 3D structured light are common to both, so room mapping and multi-level maps behave the same. The MaxV Ultra adds an RGB camera, AI object recognition, and an onboard light, giving it better judgment around socks, charging cables, and dim hallways.
The MaxV Ultra's dock washes the mop pad with 140°F water, dries it with 140°F air, adds detergent automatically for cleaner pads, and holds a larger clean water tank at 4 L versus 2.5 L. Both docks empty the dustbin on their own.
Runtime and range are effectively the same between these two, so battery life isn't a deciding factor here. Pick based on cleaning and dock features instead.
Both support Amazon Alexa, Google Assistant, Apple integration, no-go zones, multi-level maps, and smart carpet cleaning. The MaxV Ultra adds built-in voice control (no phone or speaker needed) and smart dirt detection for automatic re-cleaning of messy areas.

Both robots share the same navigation backbone, brush design, and self-emptying dock, so neither is a downgrade in the fundamentals. The MaxV Ultra earns its higher cost through camera-based obstacle avoidance, stronger suction, and a dock that fully maintains its mop. The Pro Ultra delivers most of the daily experience for far less.
