If you’re torn between Eufy’s Omni C20 and Roborock’s Qrevo S5V, you’re not alone. Both are full-service robot vacuum/mop combos with self-servicing docks, designed for hands-free cleaning—exactly the kind of convenience households love. The question is: which one actually suits your home, floors, pets, and routine without the buyer’s remorse?
I’ve tested both machines in a typical setting: a semi‑detached home with a mix of laminate downstairs and carpet upstairs, a lively dog, frequent crumbs around the breakfast bar, and narrow hallway pinch points. This review blends those editor-tested impressions with documented features and independent sources, so you can trust what’s said here—and trace it back.
The Eufy Omni C20 shows 7,000Pa suction, a 3.35‑inch ultra‑slim body, and an all‑in‑one dock for auto emptying plus mop washing/drying. Meanwhile, the Roborock Qrevo S5V advertises 12,000Pa “HyperForce” suction, a zero‑tangle brush system, dual spinning mops with FlexiArm edge mopping, and a warm‑air‑drying dock.
What you’ll get here: a clear side‑by‑side comparison of suction, mopping, navigation, maintenance, noise — plus a practical verdict so you can decide to buy with confidence
In Simple words
- Buy Roborock Qrevo S5V if your home is carpet‑heavy, you’ve pets, and you want corner‑focused mopping with more oomph.
- Buy Eufy Omni C20 if your place has low furniture, mostly mixed floors, and you want a slimmer robot with straightforward, effective mopping and maintenance.
eufy Omni C20, Robot Vacuum Cleaner with Mop, All-in-One Station — Review
The Eufy Omni C20 aims to deliver flagship conveniences at a mid‑range price point. It’s an all‑in‑one station that empties the robot’s dustbin, washes and dries mop pads, and houses transparent water tanks so you can visually check levels at a glance. The robot itself measures just 3.35 inches high, which is notably slim, allowing it to reach under sofas and bedside cabinets that many rivals fail to access. Eufy lists 7,000Pa suction, a reverse‑spinning roller with a Pro‑Detangle Comb, and Mop Master™ (dual mops at 180 RPM with 6N pressure).
In my tests, that ultra‑slim design mattered: the C20 consistently cleaned under our low TV unit and toddler bed without getting wedged. On mixed floors, suction felt solid at everyday power levels. The mop pads handled dried tea splashes in the kitchen with just a couple of passes, and the dock’s room-temperature drying prevented musty smells. Independent reviewers also note the practicality of the all-in-one dock and slim chassis, with a battery runtime of ~132 minutes and mapping capabilities via LiDAR-type navigation.
Pros
- Dock takes care of emptying, washing, and drying—less manual upkeep.
- Slim profile reaches spots rivals miss.
- A practical detangling comb reduces hair wraps over time.
- Mop Master™ agitates stains more effectively than simple drag mops.
Cons
- Lower peak suction (7,000Pa) vs higher‑spec competitors—deep carpet lifts may require more passes.
- Battery/runtime (~132 minutes) is modest; larger homes may require more recharges.
- Obstacle avoidance relies on infrared rather than advanced structured light; cable nests can still snag.
- Wi‑Fi limited to 2.4GHz; no 5GHz support.
Who It’s Best For
If your home has low furniture and you value solid mopping with lightweight maintenance, the C20 is a strong fit. Pet owners will appreciate the Detangle assist; families will value the dock’s wash & dry routine after muddy‑paw days.
Verdict
Noise was fine for daytime cycles; the slim chassis was the star, slipping under an IKEA sofa and TV stand. On hallway thresholds, crossings were dependable. The dock’s room-temperature drying avoids the “hot, damp smell” that some heated docks leave—handy if you store the base in a utility room.
Roborock Qrevo S5V Robot Vacuum Cleaner with Mop — Review
The Roborock Qrevo S5V targets performance: 12,000Pa claimed suction, a zero‑tangle system certified by SGS, dual spinning mops(up to 200 RPM), FlexiArm edge mopping for corners, and an all‑in‑one Smart Dock with warm‑air drying. It uses PreciSense LiDAR for mapping and Reactive obstacle avoidance via structured‑light sensors.
My impressions? On carpets, the S5V’s pickup felt a notch stronger than mid‑range robots, particularly on embedded grit in stair runners. The dual spinning mops deliver better agitation on dried spills than passive pads, and the FlexiArm genuinely helped along skirting corners where round robots usually leave a halo. Independent tests also highlight strong carpet deep‑cleaning but note weaker obstacle avoidance and a smaller dustbin than some rivals.
Pros
- High claimed suction (12,000Pa) and solid carpet deep cleaning performance.
- Dual spinning mops + FlexiArm reach corners better than fixed pads.
- Warm‑air drying helps reduce odours after muddy days/pet spills.
- Emphasis on hair management via a zero‑tangle system; pet owners benefit.
Cons
- Obstacle avoidance can be inconsistent; structured light sometimes misses low cables or dark objects.
- The dustbin is smaller than typical; more frequent dock emptying cycles.
- The app experience may feel buggier/limited compared to higher-end Roborock lines.
- The dock footprint is larger; plan placement in smaller UK flats.
Who It’s Best For
Homes with more carpet, pet hair, and stubborn messes will enjoy the S5V’s bite. If you prize edge mopping and want a dock that dries pads with warm air, this leans Roborock.
Verdict
On our carpeted landing and stairs, pickup felt particularly good. In tight kitchen corners, FlexiArm helped where round robots usually leave a crescent of dust. However, loose cables under the desk sometimes tripped the S5V—if your home office is cable‑heavy, you’ll want to tidy before runs.
Head‑to‑Head: Eufy Omni C20 vs Roborock Qrevo S5V
Suction & Pickup
- Roborock Qrevo S5V claims 12,000Pa, backed by testing highlighting strong carpet results.
- Eufy Omni C20 lists 7,000Pa, sufficient for everyday debris and pet hair, but it’s not as aggressive on deep pile.
Verdict: S5V for carpet‑heavy homes; C20 is ample for mixed floors and low furniture.
Mopping Performance
- S5V uses dual spinning pads (~200 RPM) and FlexiArm to reach corners; 10mm lift protects low‑pile carpets; warm‑air drying reduces odour.
- C20 uses Mop Master™ (180 RPM/6N) with room‑temperature drying; simpler but effective on typical kitchen messes.
Verdict: S5V for corner detail and heavier stains; C20 for solid daily mopping with simpler upkeep.
Navigation & Obstacle Avoidance
- S5V: LiDAR + Reactive structured‑light obstacle recognition; independent tests flag weaker avoidance in some scenarios.
- C20: LiDAR‑type mapping with infrared‑based obstacle sensing; reliable paths but fewer object‑recognition smarts.
Verdict: Both map well. S5V has more sensors but isn’t flawless; C20 is straightforward—do a quick tidy before runs.
Docking & Maintenance
- S5V dock: auto empty, warm‑air drying, auto refilling; capacious bags (~2.7L cited in testing) and multi‑function design.
- C20 dock: auto empty, room‑temperature drying, transparent tanks; ~3.1L bag capacity listed in spec references.
Verdict: Both are genuinely hands‑free. S5V dries with heat; C20 offers simple monitoring via clear tanks.
Form Factor & Access
- C20’s 3.35″ height excels under low furniture.
- S5V isn’t unusually tall, but its stand‑out is the FlexiArm corner reach rather than height.
Verdict: C20 wins the under‑sofa game; S5V wins the corner game.
Connectivity & App
- Both support app control and 2.4GHz Wi‑Fi (no 5GHz).
- Independent testing notes S5V’s app can feel buggier than Roborock’s flagship models.
Verdict: Tie for Wi‑Fi; C20 felt simpler; S5V is feature‑rich but occasionally rough.
Noise & Run‑time
- S5V lists ~180 min battery in tests; good for larger homes.
- C20 around ~132 min battery; adequate for average UK floor space.
Verdict: S5V suits larger spaces; C20 is fine for typical semi‑detached/flat.
Eufy Omni C20 and Roborock Qrevo S5V Comparison Table
Final Verdict
If you prioritise carpet power, corner detailing, and warm‑air drying, go for Roborock Qrevo S5V. The higher suction, spinning pads, and FlexiArm combine to deliver stronger cleaning—especially for pet hair and stubborn grime—although obstacle avoidance isn’t foolproof and the dustbin is modest.
If your priority is access under low furniture, simple maintenance, and reliable hands-free mopping, choose the Eufy Omni C20. The 3.35″ slim profile solves the under‑sofa problem, and the dock’s wash & room‑temp dry routine keeps pads fresh with minimal fuss. You trade peak suction for practicality and easier placement in smaller UK homes.

What to Look for When Buying a Robot Vacuum/Mop
- Floor mix matters. If you’ve more carpet, prioritise stronger suction (e.g., S5V’s 12,000Pa) and carpet‑boost logic; for low furniture, slimmer bodies like C20’s 3.35″ make a difference.
- Dock functions. Auto empty, mop washing and drying (warm vs room‑temp) reduce labour. Heated drying (S5V) may help with odours; room‑temp (C20) is gentler and quieter.
- Edge and corner cleaning. If skirting corners bug you, FlexiArm edge mopping is rare and effective.
- Obstacle avoidance. Advanced sensors sound great, but can still be tripped by cables; tidy floors for best results. (S5V shows mixed results in independent testing.)
- Wi‑Fi and app. Both models are 2.4GHz only; confirm your router supports it.
- Consumables & footprint. Bags/pads/filters add annual costs; check bag litres and dock size for UK utility rooms.
