The Saros 10R takes nearly twice the suction, dual spinning mop pads that actively scrub, and automatic mop pad detachment before carpet, all at a lower price than the older S8 MaxV Ultra. The S8 MaxV Ultra holds onto a couple of real advantages: a 20 mm mop lift versus 10 mm and 3,229 sq ft of coverage in a single run, which suits large single-level homes with thick rugs. For most buyers, though, the Saros 10R is the stronger cleaner and the better buy.
Here's an unusual situation: the newer Roborock in this matchup is also the cheaper one. The Saros 10R arrived after the S8 MaxV Ultra and brings 19,000 Pa of suction, dual spinning mop pads, and pads that pop off automatically before the robot rolls onto carpet. The S8 MaxV Ultra was built around a different idea, a vibrating mop pad that lifts a full 20 mm out of the way plus an edge mop for baseboards, paired with the longest single run coverage of the two. Both use LiDAR with AI camera and 3D structured light obstacle detection. The deciding factors come down to floor type, home size, and how much scrubbing you actually need.

The gap shows up most in value, 5.5 for the S8 MaxV Ultra against 8.6 for the Saros 10R, and that's mostly about price: the Saros 10R costs roughly 40% less. Cleaning lands at 7.3 versus 7.7 and navigation at 7.8 versus 8.4, both leaning to the Saros 10R. Features are basically a wash at 9.6 versus 9.5. Overall it's an 8.0 against an 8.7, a clear win for the newer model.
Suction is the headline: 10,000 Pa against 19,000 Pa, and the Saros 10R backs that up with a mixed rubber and bristle dual brush that grabs more from carpet pile than rubber alone. Mopping splits in two directions. The Saros 10R uses dual spinning pads, which press down and scrub rather than just wipe, and it detaches them automatically before hitting carpet. The S8 MaxV Ultra counters with a 20 mm mop lift versus 10 mm and a larger onboard water tank, so it can run longer between refills. Coverage flips the script too: 3,229 sq ft per run for the S8 MaxV Ultra against 2,150 sq ft. And the Saros 10R clears 40 mm obstacles, double the S8 MaxV Ultra's 20 mm.
At 19,000 Pa versus 10,000 Pa, the Saros 10R nearly doubles the pull, and its dual brush pairs rubber with bristles to dig debris out of carpet fibers. The S8 MaxV Ultra's all-rubber dual brush tangles less with long hair but doesn't agitate pile as aggressively.
The Saros 10R's dual spinning pads apply real scrubbing pressure, which handles dried spills better than the S8 MaxV Ultra's vibrating pad running at 4,000 vibrations per minute, though that pad plus the rotating edge mop does get closer to baseboards. Where the S8 MaxV Ultra clearly wins is the 20 mm mop lift against 10 mm, keeping pads well clear of thicker rugs, and a larger onboard water tank.
For homes with a heavy shedder, the Saros 10R's 19,000 Pa and slightly larger dust bag mean fewer missed clumps and less frequent bag changes. The S8 MaxV Ultra's 10,000 Pa and 2.5 L bag still handle daily hair fine, just with less headroom.
Both run LiDAR with AI, camera, and 3D structured light obstacle detection, so they identify and dodge socks and cords about equally well. The Saros 10R pulls ahead by climbing 40 mm thresholds versus 20 mm and lifting its side brush 22 mm, which means fewer stuck-robot rescue missions.
Both docks empty the dustbin automatically, so this is close. The Saros 10R's 2.7 L bag edges out the 2.5 L bag, stretching the time between swaps slightly.
This one splits. The Saros 10R carries the bigger 6,400 mAh battery, but the S8 MaxV Ultra covers 3,229 sq ft in a single run against 2,150 sq ft, which matters if you have a large open floor plan and don't want mid-clean recharge breaks.
Dead even here. Both offer built-in voice control plus Alexa, Google Assistant, and Apple, along with no-go zones, multi-level mapping, and smart obstacle avoidance.

The Saros 10R is the easier call for most homes: more suction, better scrubbing, higher obstacle clearance, and a lower price. Reach for the S8 MaxV Ultra only if your square footage is big enough that single-run coverage matters more, or if thick rugs make the taller mop lift essential.
