Mopping style is the real fork in the road here. The eufy Omni S1 Pro uses a roller mop, the newest and most effective wet-cleaning approach, backed by 9.8 N of downward pressure and a larger onboard water tank, so it's the pick for homes that are mostly hard floors and need real scrubbing. The Roborock S8 MaxV Ultra counters with dual rubber brushes, 10,000 Pa of suction, 3D structured light obstacle detection and a much larger single-run coverage area, making it the stronger all-rounder for big, mixed-flooring homes with pets and clutter.
One of these robots scrubs your floors with a rotating roller, the other vibrates a flat pad thousands of times a minute and adds a small spinning pad for edges. That single design choice shapes almost everything else about how they clean. The eufy Omni S1 Pro leans into hard-floor performance with a roller mop system and a bigger onboard water supply. The Roborock S8 MaxV Ultra goes wide instead, covering more square footage per run, seeing obstacles with 3D structured light, and pulling 10,000 Pa through twin rubber brushes. Both are heavily automated, both handle multi-level maps, and they land close in rating.

out of 10Roborock S8 MaxV Ultra
The gap here is small. Roborock takes the overall rating 8.0 versus 7.6, with its biggest edge in cleaning at 7.3 versus 6.8, thanks to dual rubber brushes and stronger suction. Navigation is closer at 7.8 versus 7.5, where the 3D structured light and AI obstacle system give Roborock the nod. Features land dead even at 9.6 apiece, and value ties at 5.5. Both are premium machines, so this comes down to which cleaning style fits your floors.
Start with the mop. eufy's roller system spins at 170 RPM with 9.8 N of pressure and constant contact, which is the more capable approach for dried-on messes, and it carries a larger onboard water tank so it refills the dock less often. Roborock's vibrating pad buzzes at 4,000 vibrations per minute with a small rotating edge pad for baseboards, plus a 20 mm mop lift versus eufy's 12 mm. On the vacuuming side, Roborock runs dual rubber brushes and 10,000 Pa against eufy's single rubber brush and 8,000 Pa, and it covers 3,229 sq ft per run compared to 1,976 sq ft. eufy answers with two side brushes instead of one and a robot that weighs less than half as much at 11.3 lbs.
Roborock's dual rubber brushes and 10,000 Pa give it the advantage on carpet and embedded debris, versus eufy's single rubber brush at 8,000 Pa. eufy does counter with two side brushes to Roborock's one, though Roborock's single brush extends outward to reach corners.
eufy's roller mop is the more advanced wet-cleaning design, applying 9.8 N of pressure and continuous rotation for genuine scrubbing, backed by a larger onboard water tank. Roborock's vibrating pad runs at 4,000 vibrations per minute with a small rotating edge pad and lifts a taller 20 mm to clear carpets.
Roborock is the better pet home choice with 10,000 Pa and Smart Dirt Detection, which ramps up power automatically when it rolls over a heavily soiled patch. eufy's 8,000 Pa handles surface fur fine but works the same regardless of how dirty the spot is.
Both use LiDAR mapping and dodge obstacles, but Roborock combines AI, a camera and 3D structured light with a front light for dark rooms, so it identifies cords and socks more reliably than eufy's camera-only system. Roborock also stores up to 4 floor maps versus eufy's 3.
This one's a wash. Both docks empty the dustbin automatically and handle mop maintenance, so daily upkeep looks about the same either way.
Roborock covers 3,229 sq ft in a single run against eufy's 1,976 sq ft, a real difference in a large single-story home. Its 5,200 mAh battery also outsizes eufy's 4,600 mAh.
Both offer voice control, no-go zones, multi-level maps and smart obstacle avoidance. Roborock adds Apple and built-in voice control alongside Amazon and Google, plus Smart Dirt Detection, so it fits more households and reacts to messes on its own.
