Introduction
Roborock presents three high-end models that share a surname but differ in approach and features. The Roborock Qrevo Curv 2 Flow arrives in February 2026 with an innovative proposal based on a mopping roller, whilst the Roborock Qrevo Curv 2 Pro and the Roborock Qrevo CurvX, both from 2025, opt for the traditional twin rotating mop system. This robot vacuum comparison analyses three units designed for demanding users seeking total automation in medium and large homes.
All three models integrate a multifunctional base with mop washing and drying, advanced navigation systems and obstacle-crossing capability. However, differences in power, battery life and mopping system define clearly differentiated usage profiles.
Power and Suction
Suction power draws clear hierarchies amongst these Roborock robot vacuums. The Qrevo Curv 2 Pro dominates with 25,000 Pa, a figure that exceeds the Flow by 5,000 Pa and the CurvX by 3,000 Pa. This difference translates into greater capacity to extract ingrained dirt from carpets and tile joints.
All three are equipped with Roborock's DuoDivide anti-tangle brush, a design that pushes hair and strands towards the central suction gap, significantly reducing tangles. All lift the main brush during mopping to avoid dispersing wet dirt.
The side brush system marks important differences. The Flow incorporates a twin anti-tangle side brush with automatic lifting during mopping, a useful combination to prevent the brush from touching the wet mops. In contrast, the Pro and CurvX opt for an extendable side brush that better reaches corners, although without lifting capability. For homes with many corners, the extension proves more practical; if there are carpets and vacuum-only zones, the Flow's lifting provides versatility.
Mopping
Here we find the most radical difference. The Roborock Qrevo Curv 2 Flow debuts a 270 mm mopping roller that rotates continuously, a system reminiscent of rotary mops and which, in practice, offers greater pressure and constant friction on the floor. The Pro and CurvX maintain the twin rotating mop system, proven and effective in the Qrevo range.
All three models extend their mopping systems to reach edges and skirting boards, detect dirt both on the mops and on the floor to re-clean problematic areas, and lift the system to cross carpets without wetting them. However, the lifting figures differ: the Flow raises 15 mm plus additional chassis elevation, whilst Pro and CurvX offer between 7 and 17 mm. For medium-pile carpets, the Flow provides a greater safety margin.
The Qrevo Curv 2 Pro incorporates an exclusive function: automatic mop detachment at the base when only vacuuming is needed. This avoids dragging the mops dry and simplifies maintenance. Neither the Flow nor the CurvX offer this possibility.
All three wash the mops with hot water at the base and dry them with hot air, guaranteeing hygiene and absence of odours. The Flow has a basic tray self-cleaning system, whilst Pro and CurvX integrate self-cleaning 3.0, more complete and efficient.
Navigation System
The Roborock Qrevo Curv 2 Flow features a traditional LiDAR turret, which explains its greater height of 119 mm. The Pro and CurvX incorporate retractable LiDAR that hides after use, allowing height reduction to 79.8 mm and facilitating access under low furniture, beds and sofas.
All three are equipped with a front 3D laser sensor, LED for night vision and remote camera access. The difference lies in the number of AI cameras: the Flow features just one, whilst Pro and CurvX integrate twin cameras for more precise environment recognition.
Flow and Pro recognise up to 200 different types of obstacles, from cables and slippers to toys and pet excrement. The CurvX identifies 108 objects, more than sufficient for a standard home but lower than its siblings. All three detect pets and allow remote viewing via the integrated camera.
All incorporate intelligent cleaning via SmartPlan, which adjusts power and strategy according to floor type and dirt level. Flow and Pro add specific stain recognition via AI; the CurvX lacks this function.
Battery Life and Battery
The Roborock Qrevo Curv 2 Pro leads with a 6,400 mAh battery that provides 290 minutes of battery life, sufficient to clean homes of over 250 m² in a single cycle. The CurvX features the same battery but offers 220 minutes, probably due to higher consumption from other components. The Flow is equipped with 5,200 mAh with 242 minutes of battery life, balanced for its configuration.
In practice, these differences matter especially in large houses with multiple floors or complex layouts where the robot needs to travel long distances between areas. For flats up to 120 m², any of the three completes cleaning without intermediate recharges.
Smart Functions
All three models overcome obstacles, albeit with nuances. The Flow clears steps up to 20 mm, whilst Pro and CurvX are described as capable of overcoming "single step" without specifying exact height. In homes with transitions between rooms or small level changes, the Flow provides greater documented capability.
All integrate Roborock's own voice assistant and compatibility with Alexa and Google Home, allowing complete voice control without needing to open the app.
Multifunctional Cleaning Base
All three bases auto-empty the dust bin, wash the mops with hot water and dry them with hot air. The Flow has a 2.7-litre dust bag, slightly larger than the 2.5 litres of the Pro and CurvX. This difference barely affects maintenance: all require bag changes every two to three months with intensive use.
The clean water tank is identical in all three: 4 litres. However, the Flow offers 3.5 litres of dirty water capacity versus 3 litres for the Pro and CurvX. With an additional 500 ml, the Flow allows somewhat longer mopping sessions before emptying the tray.
None include an integrated detergent tank or connection to water pipes, features reserved for higher models. The tray self-cleaning 3.0 of the Pro and CurvX surpasses the Flow's basic system, reducing the need for manual base cleaning.
Dimensions
The Roborock Qrevo Curv 2 Flow measures 353 mm in diameter and 119 mm in height due to its LiDAR turret. The Pro and CurvX share 352 mm diameter but just 79.8 mm height thanks to retractable LiDAR. This difference of almost 4 centimetres proves decisive for accessing under low furniture, trundle beds or sofas with little clearance from the floor.
All three bases measure exactly 450 x 450 x 450 mm, occupying the same space in the home. The practically identical diameter of the robots does not affect passage through doors or narrow spaces.
Real-world experience
The Roborock Qrevo Curv 2 Pro emerges as the best robot vacuum 2025 for large homes. Its 290-minute battery life, 25,000 Pa power and ability to automatically detach mops make it the most complete option for those seeking maximum automation. The reduced height of 79.8 mm allows cleaning under most furniture without manual intervention.
The Flow stands out for its innovative mopping roller system, ideal for users who prioritise results on hard floors and seek something different from the traditional mop system. Its greater lifting capacity (15 mm plus chassis elevation) and liftable side brush provide versatility in homes with carpets and frequent transitions between surfaces. The greater height limits access under some furniture.
The CurvX offers balance between features and price within this range. With 22,000 Pa suction, 220 minutes of battery life and reduced height, it covers the needs of medium-sized homes without pets that generate large amounts of hair. It recognises fewer obstacles than its siblings and lacks specific stain recognition, but maintains the essential navigation and intelligent cleaning functions.
For homes with pets, all three are equipped with the DuoDivide anti-tangle brush, although the Pro's greater power and the Flow's twin side brush configuration offer advantages in hair collection. Dirt detection on mops and floor proves especially useful when there are animals that dirty certain areas more.
