Vacuuming Performance: Raw Power vs. Intelligent Engineering

eufy OMNI S2: The Suction Beast

The eufy OMNI S2 is unapologetically powerful. Its AeroTurbo 2.0 motor generates a jaw-dropping 30,000 Pa of suction. To put that in perspective, it’s enough to lift a bowling ball. On low-pile carpets and area rugs, this translates to a deep clean that removes embedded pet hair, sand, and fine dust in a single pass. The detangle brush is a marvel of engineering—a hybrid design that uses rubber fins to flick debris into the bin while bristles agitate carpet fibers. In our tests, it handled long human hair and pet fur with zero tangles, a massive win for pet owners.

The extending side brush is another standout feature. When the OMNI S2 detects a wall or corner, it extends its side brush outward by 1.5 inches, sweeping debris from edges directly into the suction path. This eliminates the “dirt line” that most robots leave behind. On hard floors, the 30,000 Pa suction is almost overkill, but it ensures that even the finest particles in grout lines are extracted.

Roborock Qrevo Curv 2 Flow: The DuoDivide Advantage

Roborock takes a different approach with the Qrevo Curv 2 Flow. While its 20,000 Pa suction is significantly lower than the eufy, it compensates with the innovative DuoDivide brush roller. This system features two counter-rotating rubber rollers that work like a conveyor belt. Instead of flinging debris into a bin, they actively pull dirt, hair, and dust into the suction channel. This design drastically reduces hair tangling—even better than the eufy’s detangle brush in some cases—and improves pickup on medium-pile carpets.

However, the lower suction power becomes apparent on thick, high-pile carpets. The Curv 2 Flow struggles to extract deeply embedded dirt from shag or plush carpets, requiring multiple passes. The fixed side brush is competent but leaves a noticeable 1-inch gap along walls, which the eufy’s extending brush would have covered. For homes with predominantly hard floors and low-pile rugs, the Curv 2 Flow performs admirably, but it cedes the crown to the OMNI S2 for deep carpet cleaning.

Winner: eufy OMNI S2 — The 30,000 Pa suction and extending side brush provide a decisive edge for homes with mixed flooring and heavy carpet use.

Mopping Performance: The Roller Revolution

eufy OMNI S2: HydroJet 2.0 Precision

The eufy OMNI S2’s HydroJet 2.0 system is a second-generation roller mop that applies 15 Newtons (N) of downward pressure. This is roughly equivalent to a human pressing firmly with a microfiber cloth. The roller spins at high speed while being continuously wetted with fresh water from an internal reservoir. The key innovation is the self-cleaning mechanism: as the roller rotates, it scrapes against a rigid internal scraper that squeegees out dirty water and debris, depositing it into the base station’s waste tank. This means the mop is always cleaning with fresh water, not spreading dirt around.

In practice, the OMNI S2 obliterates dried-on stains like coffee, ketchup, and mud. The 15N pressure ensures that the roller conforms to uneven tile grout. It also performs edge mopping by extending the roller slightly to reach baseboards. The only downside is that the roller can leave slight streaks on glossy dark floors if the water flow is set too high, but this is easily adjusted via the app.

Roborock Qrevo Curv 2 Flow: A Promising First Attempt

The Roborock Qrevo Curv 2 Flow marks Roborock’s first foray into roller mop technology. Previously, Roborock relied on vibrating mop pads. This new system uses a cylindrical roller that rotates and vibrates simultaneously. It applies less downward pressure than the eufy (estimated around 8-10N), but it compensates with a larger contact area. The roller is self-cleaning in the dock, not on-the-fly like the eufy. After mopping, the robot returns to the base station, where the dock rinses the roller with water jets and hot air dries it to prevent odor.

In testing, the Curv 2 Flow handles everyday spills and light dirt well. It leaves floors feeling clean but not quite as “scrubbed” as the eufy. Stubborn, dried-on messes require the robot to make multiple passes. The lack of an extending mop means it leaves a 2-inch gap along baseboards, which is a noticeable drawback for meticulous cleaners. However, the vibrating action is excellent for lifting sticky residues from kitchen floors.

Winner: eufy OMNI S2 — Higher pressure, on-the-fly self-cleaning, and edge mopping make it the superior mopping machine.

eufy OMNI S2: AI Obstacle Avoidance with RGB Vision

The eufy OMNI S2 uses a combination of LiDAR for mapping and an RGB camera for obstacle recognition. The AI has been trained to identify over 100 objects, including cables, shoes, pet waste, and socks. In our tests, it successfully avoided a USB cable lying on a dark rug—a notoriously difficult scenario. The robot creates detailed maps with up to four floors, and you can set no-go zones, virtual walls, and carpet boost zones. The app is intuitive, allowing you to schedule cleanings, adjust suction and water flow per room, and view the camera feed (with privacy filters).

The only minor issue is that the RGB camera requires adequate lighting. In pitch-black rooms, the robot relies solely on LiDAR, which can’t identify objects like cables. However, for most homes, the navigation is near-flawless, with efficient path planning and minimal re-visits.

Roborock Qrevo Curv 2 Flow: 3D Structured Light Precision

Roborock employs LiDAR paired with 3D Structured Light technology. This is a step up from standard infrared sensors. The structured light projects a grid of invisible dots to create a 3D map of the environment in real-time. This allows the Curv 2 Flow to identify objects as small as a coin or a pet toy, even in complete darkness. It’s slightly better than the eufy’s camera in low-light conditions. The robot also uses Roborock’s Reactive AI 2.0, which can recognize and avoid pet waste, cables, and shoes with high accuracy.

The mapping speed is impressive—the Curv 2 Flow can scan a 1,000 sq ft home in under 10 minutes. The app is feature-rich, with support for multi-floor maps, furniture labeling, and even a “3D Map” view that renders your furniture in a virtual space. The navigation is slightly more conservative than the eufy, meaning it takes wider berths around obstacles, which can leave slightly larger uncleaned areas near furniture legs.

Winner: Tie — The eufy excels in bright conditions with its RGB camera, while the Roborock has the edge in dark environments with structured light. Both are top-tier.

Base Station & Maintenance: The Self-Cleaning Showdown

Both robots come with full-featured base stations that empty dust, wash mops, and dry them. However, there are key differences.

eufy OMNI S2 Base Station: The station uses a hot air drying system that blows 140°F air onto the mop roller for 2-3 hours. It also automatically mixes cleaning solution from a built-in reservoir. The dust bag holds 60 days of debris, and the water tanks (4L clean, 4L dirty) are generous. The self-cleaning mechanism for the mop is unique—the roller is scrubbed internally every time it rotates, meaning the base station only needs to rinse and dry.
Roborock Qrevo Curv 2 Flow Base Station: The station also offers hot air drying (130°F) and auto-refilling. It uses a dual-tank system (3.5L clean, 3.5L dirty) and a dust bag that lasts up to 7 weeks. The mop cleaning process is passive: the robot parks over a washboard, and water jets spray the roller while it rotates. This is effective but uses more water than the eufy’s internal scraper method. The station is slightly more compact than the eufy’s.

Both stations are excellent, but the eufy’s internal self-cleaning mop mechanism reduces water usage and ensures the roller is always clean during the mopping run, not just at the end.

Winner: eufy OMNI S2 — More efficient mop cleaning and larger tanks give it a slight advantage.

Price & Value: Which One Is Worth Your Money?

The eufy OMNI S2 retails for $1,199, while the Roborock Qrevo Curv 2 Flow comes in at $1,099. The $100 price difference is negligible given the features. However, value depends on your home’s needs.

If you have thick carpets, pets, or frequent spills, the eufy OMNI S2’s superior suction and mopping pressure justify the extra cost. The extending side brush and detangle brush also save you time on maintenance.
If you have a predominantly hard-floor home with low-pile rugs and want the best low-light navigation, the Roborock Qrevo Curv 2 Flow offers excellent performance for $100 less. Its DuoDivide brush is also slightly better at preventing hair tangles on the brush itself.

Winner: eufy OMNI S2 (for carpet-heavy homes) / Roborock Qrevo Curv 2 Flow (for hard-floor-focused homes).
