The Two-Robot Story
The Roborock Qrevo Curv S5X and the Roborock Qrevo Edge S5A are essentially the same robot. Same chassis, same scores across every test category, same no-camera privacy design, same Roborock ecosystem. The brief is direct on this: this unit is essentially the Edge S5A with the Curv dock design — same chassis, same privacy-friendly no-camera setup, same scores. The two meaningful differences are the dock aesthetic (Curv's curved look vs. Edge's traditional rectangular look) and one functional dust bag fit issue on the Curv dock.
If you've read the Edge S5A review, 90% of what's true there is true here. The differences are limited and specific: the Curv dock design and the dust bag fit quirk. Everything else is identical. Both versions earned the 2025 Pick of the Year in the mid-range category on the same merits.
What's in the Box and First Setup
Setup runs about 15 minutes — standard Roborock onboarding, no surprises. The Roborock app handles Wi-Fi pairing (2.4 GHz only) and LiDAR mapping. The curved Multifunctional Dock 3.0 takes more floor space than a compact dock but the curved aesthetic is the visual draw.
What's in the box: the robot, the curved Multifunctional Dock 3.0, spinning mop pads, FlexiArm Arc Side Brush, the split pressure dual roller (DuoDivide, pre-installed), starter dust bag, cleaning brush, and the charging cable.
Cleaning Performance: What It Actually Picks Up
Hard Floor & Tile Performance
18,500 Pa HyperForce suction delivers cleanly on hardwood and tile. The DuoDivide split-pressure dual roller grabs debris without flinging it, and the brushless motors keep mop-only operation as quiet as 55 dB. Mature mid-range cleaning that holds up against current-year robots.
Carpet and Pet Hair
The split pressure dual roller is designed specifically to handle long pet hair without wrapping — and it works. The brief uses the same language for both robots: vacuums up long hair and pet hair beautifully. For long-haired pet households, this is one of the better mid-range picks in the current market, on either dock variant.
Mopping Performance
Despite the dust bag fit issue, the Curv dock's other features are the same as the Edge dock. Hot water washes the mop pads. Hot air dries them. Optical dirt detect sensor auto-triggers re-cleans when wash water comes back too dirty. The dock functional feature set is the full Roborock advanced-dock package at a mid-range price.
Edge and Corner Cleaning
FlexiArm Arc Side Brush (asymmetric arc design that extends toward corners) + extendable right-side mop pad cover edges and corners along walls cleanly. Same approach as the Edge S5A — and stronger edge coverage than the Curv 2 Flow, which doesn't have FlexiArm.
Obstacle Avoidance — The No-Camera Trade-Off
Without the camera, the robot has more trouble avoiding clutter and will run over cables and small items. The Ad vs Reality obstacle claim failed in formal testing. The fix is the same as the Edge S5A: pick up the floor before sending the robot out. If your floors stay reasonably clear, the trade-off is manageable. If not, this isn't the right robot — look at the standard Qrevo Edge (with camera) or the MOVA P10 Pro Ultra Gen2 instead.
The Curv Dock — Design Choice with a Trade-Off
The Curv dock has the eye-catching curved base station design that defines Roborock's Curv product line. For buyers who care about how the dock looks in their home — and a non-trivial number do — the Curv aesthetic is the reason to pick this version over the Edge S5A. The functional feature set is identical: hot water mop washing, hot air drying, optical dirt detection sensor, tray removal, fast charging. Same workflow, different shape.
The dust bag fit quirk is the one real functional difference. The Curv dock has a known design flaw where the dust bag is too big for the cavity it sits in. The bag can't physically expand to its full capacity before it hits the cavity walls. The practical result: dust bags need to be changed sooner than the bag's stated capacity would suggest. Not a deal-breaker — most buyers will swap a bag every few months anyway — but a real ongoing maintenance frequency increase. The Edge S5A has a different dock design and doesn't have this issue.
Cost to Own
Cost to Own lands in the LOW tier — approximately $306/year OEM internal, same as the Edge S5A on the shared Roborock parts ecosystem. One real-world caveat: the Curv dock's dust bag fit issue means buyers will likely change bags more often than the projected 6/year, which would push the bag cost slightly higher in actual use. Even with that real-world bump, the total stays comfortably in the LOW tier.
Roborock Qrevo Curv S5X vs the Competition
Roborock Qrevo Curv S5X vs Roborock Qrevo Edge S5A
Same robot, two docks. If you don't have a strong preference on dock design, get the Roborock Edge S5A — same chassis, same scores, same award, no dust bag fit quirk. The Roborock Curv S5X is the right answer specifically when you prefer the Curv aesthetic or find it on a deeper sale than the Roborock Edge S5A.
Roborock Qrevo Curv S5X vs Roborock Qrevo Edge (standard, with camera)
If the no-camera obstacle weakness concerns you, the standard Roborock Qrevo Edge has a camera for stronger obstacle avoidance. Same Edge dock (no dust bag quirk), better clutter handling. The right pick for cluttered homes where you can't pre-clear the floor every run.
Roborock Qrevo Curv S5X vs MOVA P10 Pro Ultra Gen 2
Cross-brand camera-free comparison. Both are privacy-friendly picks at similar discounted price tiers. The MOVA has stronger mopping (12N + 212°F PTC) and a more mature parts ecosystem with Gen 1 part interchange. The Curv S5X has the Roborock app ecosystem and 18,500 Pa with FlexiArm corner reach.
