2026 verdict
Buyers who want the longest runtime and the lower price should pick the Roborock Qrevo Curv 2 Flow over the eufy Omni S2.
It is rated for 242 minutes against 179, carries a larger 4 L clean-water tank, and washes and dries its roller mop at the dock. The eufy Omni S2 is the stronger performer on paper, with 30,000 Pa against 20,000 Pa, a two-year warranty against one, and a dock that also doses detergent on its own, plus Matter and Apple Home support. Pick the Roborock Qrevo Curv 2 Flow for value and endurance, and the eufy Omni S2 for suction, detergent dosing and platform reach.

What the differences mean
Suction power
The eufy Omni S2 is rated at 30,000 Pa against 20,000 Pa for the Roborock Qrevo Curv 2 Flow, a gap the eufy's owners back up when they say its bin keeps airflow up instead of caking the filter.
Battery and water
The Roborock Qrevo Curv 2 Flow wins endurance: 242 minutes against 179, and a 4 L clean-water tank against the 3 L of the eufy Omni S2, so it mops more floor between fills and charges.
Detergent dosing
The eufy Omni S2 dock dispenses cleaning solution on its own as part of its routine. The Roborock Qrevo Curv 2 Flow is detergent compatible but has no automatic dispenser, so solution is measured in by hand.
Warranty
eufy covers the Omni S2 for two years and Roborock covers the Qrevo Curv 2 Flow for one, which matters on a machine with a washing dock and moving parts.
Slimness
The Roborock Qrevo Curv 2 Flow stands 119 mm tall and the eufy Omni S2 98 mm, both too tall for the lowest furniture but the eufy reaches under sofas the Roborock cannot.
Which one to buy if
- you want the longest runtime and the lower price
The Roborock Qrevo Curv 2 Flow is rated for 242 minutes with a 4 L tank and costs less.
- maximum suction and mop strength matter most
The eufy Omni S2 is rated at 30,000 Pa and its owners rate the roller mop above pad systems.
- you want detergent dosed automatically
The eufy Omni S2 dock dispenses cleaning solution on its own, which the Roborock does not.
- your home has low furniture
At 98 mm the eufy Omni S2 is the shorter of the two, so it reaches under more sofas and beds.

What owners say
Owners of both rollers report floors that stay visibly cleaner with less intervention, then point to different strengths. Roborock Qrevo Curv 2 Flow owners praise how little attention it needs: LiDAR mapping that holds up, obstacle recognition that avoids cables, and anti-tangle brushes that keep hair off the roller, all run daily for weeks without a rescue. Their honest weak spot is edge cleaning, which stops short of baseboards and low cabinet kicks, with a minority reporting streaking on hardwood. eufy Omni S2 owners put the mop first, saying the roller lifts ingrained mud and sticky marks better than pad mops, and rate the obstacle avoidance among the best in class. Their frustrations are software that loses its way on complex layouts, a tall body, a very large dock and uneven reliability.
