Two different mopping philosophies are on the table here: eufy's roller mop, which rinses itself continuously as it cleans, versus Roborock's dual spinning pads that scrub with an extendable arm and get washed in 176°F water back at the dock. The Qrevo CurvX pulls ahead on coverage (4,305 sq ft in a single run), obstacle avoidance hardware, and dock capacity, making it the pick for larger, cluttered, multi-story homes. The Omni E28 counters with two side brushes, a bigger onboard dustbin, automatic detergent dispensing, and a lower price, which suits smaller homes where thorough edge pickup matters more than marathon range.
Roller mops are the newest thing in robot mopping, and the eufy Omni E28 is one of the models betting on them. Roborock's Qrevo CurvX takes the proven route instead: two spinning pads pressed against the floor, one of which extends past the chassis to reach baseboards. That single design choice ripples through the whole comparison, affecting how each robot handles edges, how the dock maintains the mop, and how much water each one carries. Add a wide gap in single-run coverage and different obstacle sensing setups, and the decision comes down to home size and floor type more than anything else.
eufy Omni E28
out of 10Roborock Qrevo CurvX
The Roborock Qrevo CurvX takes the overall rating at 8.9 against the eufy Omni E28's 8. Most of that gap comes from features, where Roborock rates 7.9 to eufy's 6.6, meaning more mopping and self-cleaning extras built in. Roborock also cleans better, 8.7 to 8, so it picks up more on the first pass. The eufy fights back on navigation with an 8.9 to Roborock's 8.1, so it maps rooms and dodges obstacles more reliably. Both offer good value for what you pay.
Range is where the split is widest. The Qrevo CurvX covers 4,305 sq ft in one run off a 6,400 mAh battery, versus 1,600 sq ft and 5,200 mAh for the Omni E28, so big open floor plans finish in a single pass with the Roborock. Mop maintenance differs too: Roborock washes its pads in 176°F water and cleans its own dock tray, and eufy answers with automatic detergent dispensing plus warmer 122°F pad drying. On the floor, the E28 sweeps with two side brushes and holds more debris in a 300 mL onboard bin against Roborock's 258 mL. Obstacle handling favors Roborock, which pairs AI, a camera, and 3D structured light, and climbs 40 mm thresholds against the eufy's 21 mm.
Roborock edges the suction number at 22,000 Pa versus 20,000 Pa, but the eufy uses two side brushes to Roborock's one and carries a larger 300 mL onboard dustbin, which helps it sweep corners and go longer between dock trips. Both run the same dual rubber-and-bristle main brush, so day-to-day pickup on carpet and hard floors is close.
The Omni E28's roller mop is the newer approach and presses harder at 14.7 N, but Roborock's dual spinning pads spin at 200 RPM, extend outward to reach baseboards, lift a full 17 mm to clear carpet (against 10.5 mm), and get washed in 176°F water back at the dock. Roborock also offers freely adjustable water levels rather than three fixed settings.
Roborock's 22,000 Pa gives it a slight pull advantage on embedded fur, and its liftable main brush helps when tangles build up. The eufy's larger 3 L dust bag means fewer bag changes during heavy shedding season.
Both use LiDAR plus a camera, but Roborock layers AI and 3D structured light on top of its camera and LED setup and climbs 40 mm obstacles versus 21 mm, so cords and thresholds cause fewer stalls. The eufy answers with accurate mapping across up to 5 stored floor levels, one more than Roborock supports.
Roborock's dock holds more of everything (a larger clean water tank and a larger dirty water tank), washes pads with hot water, and cleans its own tray. The eufy dock adds detergent automatically when washing the mop for a cleaner rinse, holds a bigger dust bag, and dries pads at a warmer 122°F.
Runtimes are nearly identical at 220 minutes for Roborock and 216 for eufy, but the Qrevo CurvX covers 4,305 sq ft in a single run against 1,600 sq ft for the Omni E28. That difference matters most in large single-level homes where you want the job done in one pass.
Both work with Amazon Alexa, Google Assistant, and Apple, and both support no-go zones, multi-level maps, smart carpet cleaning, and obstacle avoidance. Roborock adds built-in voice control, so you can issue commands directly to the robot without going through a smart speaker.

Big house with lots of hard flooring and clutter? The Qrevo CurvX handles it with more coverage, better obstacle sensing, and a stronger mopping setup. Smaller home, tighter budget, and a focus on tidy edges and easy dock upkeep? The Omni E28 delivers most of the automation for noticeably less.
