Roborock Qrevo S5V vs CurvX: Roborock Mid-Range Lineup Explained

Cleaning Performance

The suction gap here is massive: 22,000Pa (CurvX) vs 12,000Pa (S5V). That’s 83% more suction, and the difference is immediately apparent on carpet. The CurvX pulls embedded dirt, fine dust, and pet hair from medium-pile carpet that the S5V simply can’t reach. On independent testing, the CurvX scores significantly higher on carpet debris removal.

On hard floors, the gap narrows — both robots handle surface debris well, and the S5V’s 12,000Pa is more than adequate for dust, crumbs, and hair on smooth surfaces. Daily hard-floor maintenance cleaning is comparable.

Both share Roborock’s DuoDivide anti-tangle main brush and FlexiArm extending side brush. The FlexiArm on both models extends to sweep along walls and into corners, which is a genuine advantage over competitors without extending brushes.

The CurvX adds warm water on-robot mopping — heating water before it hits the floor for better stain removal during the cleaning pass. The S5V uses room-temperature water. For mopping, this gives the CurvX an edge on anything beyond light dust.

Winner: Roborock Qrevo CurvX — 83% more suction is not a marginal upgrade. It’s a different tier of cleaning capability.

Design & Mobility

The CurvX’s 3.14-inch ultra-slim profile is one of its defining features. Most robot vacuums sit at 3.5-4+ inches tall, which means they can’t clean under many bed frames, sofas, and entertainment centers. The CurvX slides under furniture that blocks the S5V entirely.

The CurvX also adds AdaptiLift chassis technology, which adjusts the robot’s ground clearance to climb over door thresholds and carpet transitions up to 4cm. The S5V has standard threshold climbing that handles smaller transitions but struggles with taller door tracks.

Both robots use LiDAR navigation for accurate mapping and efficient cleaning paths. The CurvX upgrades to Reactive AI 3.0 with structured light for obstacle avoidance, while the S5V uses LiDAR-based Smart Obstacle Avoidance. In practice, both navigate well and avoid most household obstacles, but the CurvX is more consistent with small objects like cables and shoes.

Build quality is comparable — both feel solid and well-made, which is typical of Roborock’s lineup.

Winner: Roborock Qrevo CurvX — Ultra-slim profile and AdaptiLift provide meaningfully better mobility.

Dock Features

The CurvX ships with the Multifunctional Dock 3.0 Thermo+: 176°F hot water mop washing, 113°F warm air drying, auto-emptying, and auto water refilling. The hot water washing provides genuine bacterial reduction and more effective mop pad cleaning.

The S5V’s dock is simpler: auto-emptying (2.7L E12 dust bag lasting ~7 weeks), mop washing with a slow pre-wash and high-speed spin dry, warm-air drying, auto water refilling, and fast/off-peak charging. Notably, the S5V’s dock doesn’t use hot water for mop washing — it relies on mechanical washing and drying.

The S5V’s dock does support fast charging and off-peak charging scheduling, which is a nice energy-management feature. But the hot water washing on the CurvX dock is a more impactful upgrade for hygiene and mop pad cleanliness.

Both docks are full all-in-one stations that handle emptying, washing, and drying automatically. The CurvX dock simply does it with hotter water.

Winner: Roborock Qrevo CurvX — 176°F hot water mop washing is a meaningful hygiene upgrade.

Battery & Runtime

The S5V runs up to 180 minutes on its battery. The CurvX’s 5,200mAh battery delivers around 150 minutes — about 30 minutes less. This is one area where the S5V has a clear advantage.

For homes under 1,500 sq ft, both complete a full clean on one charge. For larger homes or homes with heavy carpet (which demands higher suction and more power), the S5V’s extra runtime provides more cushion.

The CurvX’s higher suction draws more power, which partially explains the shorter runtime despite being a newer model. This is a trade-off inherent to its design: more cleaning power per minute, but fewer total minutes.

If your home is over 2,000 sq ft and you run max suction, the S5V may complete the job without recharging where the CurvX might need a mid-clean dock visit. For most homes, though, 150 minutes is still sufficient.

Winner: Roborock Qrevo S5V — 30 minutes more runtime is relevant for larger homes.

Value & Price

The S5V typically sells for $499-549. The CurvX typically sells for $799-899. That’s a $300-350 price gap.

For that $300-350, the CurvX upgrades: suction from 12,000Pa to 22,000Pa (+83%), height from standard to 3.14 inches, threshold crossing with AdaptiLift, warm water on-robot mopping, and hot water dock washing. It trades: 30 minutes of battery life.

This is one of the most clear-cut upgrade decisions in the robot vacuum market. The CurvX doesn’t just improve on the S5V — it transforms the experience. The suction and slim design alone justify the price difference, and the dock and mopping upgrades make it even more compelling.

The S5V is still a good robot vacuum. If $500 is your firm budget, it delivers solid daily cleaning with FlexiArm edge coverage and a capable all-in-one dock. But if you can stretch to $800-900, the CurvX is the significantly better investment.

Winner: Roborock Qrevo CurvX — The upgrades comprehensively justify the $300 premium.
