The Saros 10R nearly doubles the suction of the S8 MaxV Ultra, adds dual spinning mop pads that actively scrub instead of vibrate, and clears taller obstacles, all for less money. The S8 MaxV Ultra holds onto a couple of real advantages: it covers over 1,000 more square feet in a single run and lifts its mop a full 20 mm off the floor, which matters for thick carpet. Big homes with deep pile favor the S8 MaxV Ultra, but most buyers get more cleaning for less with the Saros 10R.
Here's an unusual situation: the newer Roborock in this pairing is also the cheaper one. The Saros 10R arrived with 19,000 Pa of suction, dual spinning mop pads, and a 40 mm obstacle clearance, and it sits below the S8 MaxV Ultra on price. That flips the usual logic of buying an older premium model to save money. So the real question isn't which robot costs less, it's whether the S8 MaxV Ultra's larger single-run coverage and taller mop lift are worth paying extra for. For a lot of homes, they aren't. For some, they absolutely are.

out of 10Roborock Saros 10R
The Saros 10R takes this one with an 8.9 overall rating against 8.1 for the S8 MaxV Ultra. The biggest gap is navigation, where the Saros 10R earns 9.3 to the S8 MaxV Ultra's 7.9. In practice that means fewer stuck moments, smarter obstacle dodging, and less rescuing on your part. Cleaning follows the same pattern at 8.8 versus 8.1, so the Saros 10R picks up more on a single pass. Features tie at 8.6, so both give you the same app control, mopping tricks, and dock conveniences.
Suction is the headline: 19,000 Pa on the Saros 10R against 10,000 Pa on the S8 MaxV Ultra, paired with a mixed rubber and bristle dual brush instead of all-rubber. Mopping takes different approaches too. The S8 MaxV Ultra uses a vibrating pad running at 4,000 vibrations per minute plus a small rotating edge mop, whereas the Saros 10R runs dual spinning pads that press and scrub the floor. Coverage swings the other way, with the S8 MaxV Ultra handling 3,229 sq ft per run compared to 2,150 sq ft. And the Saros 10R climbs 40 mm obstacles versus 20 mm, lifts its side brush 22 mm to avoid tangles, and can detach its mop pads automatically before hitting carpet.
The Saros 10R's 19,000 Pa nearly doubles the S8 MaxV Ultra's 10,000 Pa, and its dual brush mixes rubber with bristles to agitate carpet fibers rather than just skim them. Both are strong on hard floors, but the Saros 10R pulls more out of medium and high pile.
The Saros 10R's dual spinning pads apply active scrubbing pressure, which handles dried spills better than the S8 MaxV Ultra's vibrating pad, and it offers 30 moisture levels plus a hotter 176 °F pad wash. The S8 MaxV Ultra counters with a 20 mm mop lift (double the Saros 10R's 10 mm) and a larger onboard water tank, so it keeps thick carpet drier and refills less often mid-run.
Pet homes lean toward the Saros 10R here thanks to 19,000 Pa pulling embedded hair from rugs, a slightly larger dock dust bag, and a side brush that lifts 22 mm to reduce tangling. The S8 MaxV Ultra still handles daily shedding fine, it just works harder on carpet.
Both robots run the same combination of LiDAR, camera, AI, and 3D structured light for spotting objects on the floor. The Saros 10R separates itself by climbing 40 mm thresholds and obstacles versus 20 mm, so it crosses transition strips and thicker rug edges the S8 MaxV Ultra has to route around.
Both docks empty the bin, wash the pads, and dry them with heat, so this one is close to even. The Saros 10R washes pads at 176 °F for a deeper clean, and the S8 MaxV Ultra dries at 140 °F with a slightly larger dirty water tank in the dock.
The S8 MaxV Ultra covers 3,229 sq ft in a single run against 2,150 sq ft for the Saros 10R, which matters in large open layouts where fewer recharge breaks means faster finishes. The Saros 10R carries the bigger 6,400 mAh cell but spends more of it on higher suction.
This is a genuine tie. Both work with Amazon Alexa, Google Assistant, Apple, and Roborock's built-in voice control, and both handle no-go zones, multi-level maps, smart carpet detection, and AI obstacle avoidance through the same app.

For most homes, the Saros 10R is the easier call: more suction, better scrubbing, taller obstacle clearance, and a lower price. The S8 MaxV Ultra earns its place in big houses with plush carpet, where 3,229 sq ft of single-run coverage and a 20 mm mop lift genuinely change the daily routine.
