Quick Verdict
The Qrevo Curv is the better robot vacuum, and right now it is also the cheaper one. Roborock's US store lists the Curv at $849.99 — a 47%-off sale against its $1,599.99 list price — while the newer Qrevo S5V sits at $899.99 with no discount (both checked October 21, 2026). For $50 less than the S5V, the Curv gives you 18,500Pa suction against 12,000Pa, 167°F hot-water mop washing (the S5V dock does not heat its wash water), a liftable AdaptiLift chassis that climbs up to 4cm thresholds, and AI obstacle recognition. TechRadar's hands-on review scored it 4.5/5 for performance and 5/5 for design, calling it the model many consider Roborock's flagship.
The Qrevo S5V is the newer mid-range pick, and it only wins on value when discounted. It shares the Curv's DuoDivide zero-tangle brush system (SGS-certified 0% tangling), and Vacuum Wars' independent lab tests measured genuinely strong results: 0% hair tangles, 92% carpet deep-clean pickup (their 4th-best score of 205+ robots) and 92% pet-hair removal. But its obstacle avoidance scored 6 out of 24 in the same tests — one of the worst results on record — and at full $899.99 it costs more than the discounted flagship. Vacuum Wars' own conclusion matches: a great value robot vacuum, but only if you can find it at a discounted price.
Current Verified Prices
Roborock's own US store listed these prices on October 21, 2026: Qrevo S5V at $899.99, shown with no sale discount; Qrevo Curv at $849.99, displayed as a sale at 47% off the $1,599.99 list price. That puts the higher-tier Curv $50 below the S5V today — an inversion caused entirely by the Curv's temporary sale. If the Curv sale ends and it returns toward $1,599.99, the value math flips and the S5V becomes the cheaper option by a wide margin.

Exact Models and Official Specifications
This comparison covers the US Roborock Qrevo S5V and the US Roborock Qrevo Curv (the 2024 flagship, not the newer CurvX or Curv 2 Flow — those are separate models). Both are vacuum-and-mop combos with all-in-one docks sold through Roborock's US store. The figures below come from Roborock's official Qrevo S5V page and official Qrevo Curv page, checked October 21, 2026.
Scroll horizontally to compare all columns →
| Official specification | Qrevo S5V | Qrevo Curv | What changes the decision |
|---|---|---|---|
| Suction | 12,000Pa HyperForce | 18,500Pa HyperForce | The Curv's rated suction is 54% higher; the gap shows most on carpet and in crevices. |
| Main brush | DuoDivide brush, Triple Anti-Tangle System, SGS-certified 0% tangling | DuoDivide brush, Dual Anti-Tangle System, SGS- and TÜV-certified 0% tangling | Both use the same tangle-free brush concept; independent tests confirm the S5V side lives up to it. |
| Side brush | FlexiArm side brush (fixed, anti-tangle) | FlexiArm Arc side brush (extends past the edge) | The Curv's extending side brush cleans along walls and furniture legs more aggressively. |
| Mopping | Dual spinning mops up to 200 RPM, FlexiArm edge mopping, 10mm mop lift | Dual spinning mops, FlexiArm edge mopping, liftable mops | Both cover edges; the difference is in how the dock treats the mops (next row). |
| Mop washing | Self-washing with warm-air drying (no heated wash water) | 167°F (75°C) hot-water mop washing with three temperature settings, warm-air drying | Hot water dissolves grease and kills over 99.99% of mop bacteria per Roborock; the S5V's dock skips it. This is the Curv's biggest practical advantage. |
| Chassis | Fixed chassis, crosses thresholds up to 2cm | AdaptiLift chassis: lifts 10mm, crosses standard thresholds up to 3cm and double-layer thresholds up to 4cm | The Curv handles sunken floors, high door bars and medium-pile carpet transitions the S5V cannot. |
| Obstacle avoidance | Reactive Tech (structured light, no camera) | Reactive AI Obstacle Recognition | Vacuum Wars measured the S5V avoiding only 6 of 24 test obstacles — a genuine weakness. The Curv's AI recognition is the safer bet in cluttered rooms. |
| Navigation | PreciSense LiDAR, multi-floor mapping up to 4 floors | PreciSense LiDAR, Roborock SmartPlan | Both map with LiDAR; the Curv adds SmartPlan automated scheduling. |
| Dock | Multifunctional Dock: auto-empty (2.7L bag, ~7 weeks), auto tank refill, 30% faster charging, off-peak charging | Multifunctional Dock 3.0: auto-empty, auto tank refill, hot-water mop wash, intelligent dirt detection (re-wash/re-mop), dock self-cleaning | Dock 3.0 washes itself and re-cleans dirty mops automatically; the S5V dock is capable but more manual. |
| Voice and extras | Alexa, Google Assistant, Siri Shortcuts | "Hello Rocky" voice assistant, video call and cruise, pet snaps, Alexa/Google | The Curv doubles as a mobile pet camera; the S5V sticks to cleaning. |
| Wi-Fi | 2.4GHz only (5GHz not supported) | 2.4GHz only (5GHz not supported) | Identical limitation — enable the 2.4GHz band on the router for either model. |
Pros and Cons from Published Reviews
The observations below come from Vacuum Wars' purchased, independently tested review of the Qrevo S5V, TechGearLab's hands-on S5V review, and TechRadar's hands-on review of the Qrevo Curv. They describe tested samples, not guaranteed results for every unit.
Scroll horizontally to compare all columns →
| Trade-off | Qrevo S5V | Qrevo Curv |
|---|---|---|
| Pro 1: cleaning performance | Vacuum Wars measured 92% carpet deep-clean pickup — their 4th-best score across 205+ robots — plus 92% pet-hair removal and a 217-point overall mopping score (average: 188). | TechRadar awarded full marks for vacuuming: it “sucks like a limpet,” with excellent pickup on all flooring types and remarkably well-behaved performance on loose rugs. |
| Pro 2: hair management | 0% hair tangles in Vacuum Wars' 7-inch hair test (average robot: 38% wrapped), matching Roborock's SGS-certified 0% claim. | Same DuoDivide brush concept with SGS and TÜV certification; TechRadar praised the pop-out FlexiArm side brush for edge work. |
| Pro 3: mopping and hygiene | Dual 200-RPM spinning mops with FlexiArm edge extension; TechGearLab found it mopped up a dried-on coffee spill completely. | 167°F hot-water mop washing with intelligent dirt detection that re-washes dirty mops and re-mops dirty floors — a full hygiene tier above the S5V. |
| Pro 4: value right now | A strong mid-range package when discounted — Vacuum Wars calls it one of the best value robots in its class at a discount. | At $849.99 on sale it undercuts the S5V by $50 while offering flagship hardware; TechRadar scored it 4/5 for value even before considering the sale. |
| Con 1: obstacle avoidance | Only 6 of 24 obstacles avoided in Vacuum Wars' tests — one of the worst scores on record — and owner reports of pet-waste encounters. The structured-light system without a camera is the weak link. | No equivalent lab failure on record, but AI obstacle recognition still misses small flat objects occasionally; keep floors reasonably clear. |
| Con 2: suction vs rating | Bench-tested suction (0.47 kPa) came in well below the 16-robot average (0.83 kPa) despite the 12,000Pa rating — the rating does not fully translate to measured airflow. | No such discrepancy reported; the 18,500Pa rating is backed by TechRadar's full-marks vacuuming assessment. |
| Con 3: app and refinement | Vacuum Wars found the app buggier and more limited than on Roborock's higher-end models, and the dock lacks hot-water washing. | The app is extremely comprehensive (5/5) but takes time to learn; the premium hardware comes with a premium list price when the sale ends. |
The Price Inversion Is the Real Story
Normally this comparison would be simple: the Curv is the flagship at $1,599.99, the S5V is the mid-range at $899.99, and you pay $700 for the upgrade. Today the Curv's 47%-off sale collapses that gap to negative $50 — the flagship costs less than the mid-range. That makes the Curv the obvious pick while the sale lasts, but it also makes the decision fragile: if the sale ends, the S5V at $899.99 becomes the value choice by $700. Do not buy on today's prices alone; check both listings on the day you order and re-run the math.
Suction and Carpet: Do You Need 18,500 Pa?
Probably not for the number alone — but the measured results behind it matter. Vacuum Wars' carpet deep-clean test is the great equalizer: the S5V's 92% pickup beat robots with much higher ratings, proving that brush design and airflow management outweigh the headline Pascal figure. Still, the Curv pairs its higher rating with TechRadar's full-marks vacuuming verdict, while the S5V's bench suction tested below average. For homes with mostly carpet and pets, the Curv's combination of rating plus measured performance is the safer bet; for mixed floors where the S5V already scores 92%, the suction gap is less decisive than the price gap.
Mopping: Hot Water vs Warm Air
This is the clearest functional divide. The Curv's dock heats wash water to 167°F, which dissolves greasy kitchen messes and eliminates over 99.99% of mop bacteria according to Roborock, then checks whether the mops are actually clean and re-washes them if not. The S5V's dock washes with unheated water and dries with warm air — fine for maintenance mopping, as TechGearLab's dried-coffee-spill test showed, but a step down for hygiene. If mopping is a primary job (kitchens, dining areas, pets), the Curv's hot-water system is worth real money. If you mostly vacuum and mop lightly, the S5V's system is adequate.
Thresholds, Furniture and Clutter
The Curv's AdaptiLift chassis is genuinely different hardware: it lifts the whole body 10mm and climbs double-layer thresholds up to 4cm — the highest Roborock claims in the industry — where the S5V manages 2cm. Sunken living rooms, high door bars and thick rug edges are Curv territory. On obstacle avoidance the gap is even starker: the S5V's 6-of-24 result is a documented weakness, while the Curv's AI recognition is the more capable system. Homes with kids, pets and cluttered floors should weight this section heavily toward the Curv.
Which Should You Buy?
- Buy the Qrevo Curv while it is $849.99 on sale: stronger suction, hot-water mop washing, liftable chassis and better obstacle avoidance for $50 less than the S5V. This is the best value in Roborock's lineup at today's prices.
- Buy the Qrevo S5V if the Curv sale ends: at $899.99 against a full-price Curv, the S5V's Vacuum Wars test scores (92% carpet pickup, 0% tangles) make it the rational mid-range pick.
- Pet-heavy homes: lean Curv — stronger suction plus the better obstacle-avoidance system matters when pet waste is a risk.
- Kitchens and dining areas: Curv — hot-water mop washing is the decisive hygiene feature.
- Simple apartments with mixed floors: the S5V is enough, but only buy it discounted; Vacuum Wars' own verdict ties its value to finding it on sale.
- Low furniture and high thresholds: Curv — AdaptiLift's 4cm climbing has no equivalent on the S5V.

FAQ
Is the Roborock Qrevo Curv better than the Qrevo S5V?
On hardware, yes: the Curv has 18,500Pa suction (vs 12,000Pa), 167°F hot-water mop washing, a liftable AdaptiLift chassis and AI obstacle recognition. It is also currently $50 cheaper on sale ($849.99 vs $899.99, checked October 21, 2026). The S5V's strengths are its newer mid-range positioning and strong Vacuum Wars test scores — but only at a discount.
Why is the Qrevo Curv cheaper than the Qrevo S5V right now?
The Curv is Roborock's 2024 flagship on a temporary 47%-off sale ($849.99 vs the $1,599.99 list price), while the newer S5V sits at its full $899.99 price. Sale prices end without notice — if the Curv returns to full price, the S5V becomes the cheaper option by about $700.
Which is better for pet hair, the S5V or the Curv?
Both use Roborock's DuoDivide brush with a certified 0% hair-tangling rate, and Vacuum Wars measured 0% tangles and 92% pet-hair pickup on the S5V. The Curv adds stronger suction for embedded hair. Either handles pet hair well; the Curv's better obstacle avoidance is the tiebreaker in homes where pet waste is a risk.
Which mops better, the Qrevo S5V or Qrevo Curv?
The Curv: its dock washes mops with 167°F hot water, checks cleanliness and re-washes automatically. The S5V's dock washes with unheated water and warm-air dries. Both have FlexiArm edge mopping, and the S5V mopped up a dried-on coffee spill completely in TechGearLab's test — but for hygiene the Curv is a tier above.
Do the Qrevo S5V and Qrevo Curv support 5GHz Wi-Fi?
No. Roborock's official pages state 2.4GHz only for both models. Enable the 2.4GHz band on your router before setup.
