Introduction
The Dreame L10s Ultra Gen 2 and the Roborock Qrevo Curv represent two high-end propositions launched in 2024, designed for users seeking robot vacuum cleaners with a complete multifunctional base. Both units integrate mop washing and drying systems, advanced laser navigation and mopping capabilities with side extension, but their technical approaches differ notably in aspects such as suction power, artificial intelligence and obstacle-climbing ability.
The Dreame model positions itself as a balanced option with a more competitive price, whilst the Roborock Qrevo Curv opts for more advanced technology in navigation and environment recognition. For homes with thick carpets, steps or multiple obstacles, these differences can prove decisive.
Power and Suction
The power difference between these models is considerable. The Roborock Qrevo Curv reaches 18500 Pa, almost double the 10000 Pa of the Dreame L10s Ultra Gen 2. This advantage translates into greater capacity to extract ingrained dirt from long-pile carpets or to vacuum heavy debris such as sand or compacted soil.
Regarding the main brush, the Dreame features a HyperStream system that can be fitted with an optional anti-tangle brush, although it doesn't come installed as standard. The Roborock incorporates the DuoDivide system, specifically designed to prevent hair tangles and which can also be raised during mopping. This main brush elevation is only present on the Roborock model, allowing more efficient mopping without the brush interfering with the mops.
The side brush also marks differences. The Qrevo Curv features an extendable and anti-tangle side brush, characteristics absent on the L10s Ultra Gen 2. The side extension allows the Roborock to clean corners and edges better, reaching areas that would normally be out of the robot's reach.
Mopping
Both units integrate rotating mops with side extension capability. The Dreame uses its Roboswing 3.0 system, whilst the Roborock opts for FlexiArm. Mop lift reaches 10.5 mm on the Dreame and between 10-20 mm on the Roborock, sufficient in both cases to travel over thin carpets without wetting them.
Where the difference becomes notable is in mop washing. The Dreame L10s Ultra Gen 2 washes the mops with cold water, an effective system for most everyday situations. The Roborock Qrevo Curv, however, heats the water up to 75°C during mop washing, which improves the removal of grease and stubborn stains. Drying in both cases is carried out with hot air at 45°C.
The Roborock adds dirt detection both on the mops and on the floor, automatically adjusting mopping intensity or repeating passes when it detects dirtier areas. This function is not available on the Dreame. Neither model allows leaving the mops on the base to perform vacuum-only tasks without having to remove them manually.
Navigation System
Both robots feature LIDAR 3D laser turret and front sensors to avoid obstacles. The main difference lies in the presence of an AI camera. The Dreame L10s Ultra Gen 2 doesn't incorporate a camera, whilst the Roborock Qrevo Curv integrates a dual camera system with LED for night vision and remote access.
This camera allows the Roborock to recognise up to 62 different types of obstacles and offers the possibility of connecting remotely to monitor the home. The Dreame relies solely on 3D laser sensors for object detection, an effective system but less precise in the specific recognition of items such as shoes, cables or toys.
Both models feature pet recognition and intelligent cleaning systems: CleanGenius on the Dreame and SmartPlan 2.0 on the Roborock. The Qrevo Curv's algorithm runs on RR Mason 11.0, although the Dreame doesn't specify its processing platform.
Autonomy and Battery
The Roborock Qrevo Curv is equipped with a 6400 mAh battery versus the 5200 mAh of the Dreame L10s Ultra Gen 2. Despite this difference, both robots declare the same autonomy of 240 minutes. The Roborock's greater battery capacity compensates for its superior suction power, maintaining equivalent working times.
For large homes, this autonomy is sufficient to complete full cleans without the need for intermediate recharges. Neither manufacturer specifies the full charging time nor the maximum recommended surface area.
Smart Functions
Obstacle-climbing ability varies significantly. The Dreame L10s Ultra Gen 2 can overcome up to 20 mm in height, whilst the Roborock Qrevo Curv reaches between 30 and 40 mm. In practice, this means the Roborock can climb higher steps, travel over thick carpets more easily and navigate obstacles such as cables or furniture bases that could stop the Dreame.
The Roborock includes a basic built-in voice assistant, a function absent on the Dreame. Neither model incorporates a robotic arm.
Multifunctional Cleaning Base
The bases of both robots offer auto-emptying, mop washing and drying, but with differences in some details. The Dreame L10s Ultra Gen 2 integrates a detergent tank to dispense product during mop washing, a feature that the Roborock Qrevo Curv doesn't include.
The wash tray self-cleaning works differently. The Dreame features a second-generation system that requires some manual maintenance, whilst the Roborock incorporates more advanced 2.0 self-cleaning, reducing user maintenance tasks.
The dust bag capacity is greater on the Dreame, with 3.2 litres versus the 2.5 litres of the Roborock. The clean water tanks also favour the L10s Ultra Gen 2: 4.5 litres against 4 litres. Dirty water is stored in 4 litres on the Dreame and 3 litres on the Roborock. These differences can translate into fewer emptyings and refills on the Dreame model.
The Dreame offers an optional kit for connection to plumbing, although it must be purchased separately. The Roborock doesn't have this option. Neither includes UV disinfection nor integrated plumbing connection as standard.
Dimensions
The Dreame L10s Ultra Gen 2 measures 97 mm in height, 6 mm less than the 103 mm of the Roborock Qrevo Curv. For homes with low furniture or beds with little clearance, these millimetres can determine whether the robot accesses certain areas or not. The diameter is practically identical: 350 mm on the Dreame and 352 mm on the Roborock.
The robot's dust bin is slightly larger on the Roborock (325 ml versus 300 ml), although the difference is of little relevance given that both self-empty into the base. The robot's water tank is identical on both: 80 ml.
The base dimensions differ notably. The Dreame base is taller (590.5 mm) and narrower (340 mm), with a depth of 456.7 mm. The Roborock's forms a more compact cube of 450 mm in all its dimensions. This can influence the available location in the home.
Real-world experience
For large homes with multiple rooms, both robots offer sufficient autonomy. The Roborock excels in houses with thick carpets or uneven floors thanks to its greater obstacle-climbing ability and its almost double suction power. The extendable side brush also improves cleaning in corners and edges.
In homes with pets, the Roborock's DuoDivide system, which comes installed as standard with anti-tangle technology, represents an advantage over the Dreame, which requires the optional purchase of the anti-tangle brush. The Qrevo Curv's greater power is also more effective at extracting hairs embedded in textiles.
The Roborock's hot water mop washing offers better results in kitchens or areas with grease, whilst the Dreame incorporates a detergent tank to enhance washing. The Roborock's dirt detection adds a superior level of automation.
For those seeking to access under low furniture, the Dreame with its 97 mm height has an advantage. The Roborock's camera with remote access may prove attractive for those who value home monitoring in addition to cleaning.
Conclusion: Which to choose?
Choose the Dreame L10s Ultra Gen 2 if you're looking for a complete solution at a more competitive price, you value having an integrated detergent tank and greater capacities in the base tanks. Also if you need the robot to access under low-height furniture or if you prefer the option of connecting the base to plumbing in the future via an optional kit.
Choose the Roborock Qrevo Curv if you need maximum suction power for carpets or pet hair, want hot water mop washing and advanced wash tray self-cleaning. It's the best option for homes with significant uneven floors, multiple obstacles or if you value intelligent recognition via dual camera and remote access. The extendable side brush and standard anti-tangle system make it a superior option for homes with pets and demanding edge cleaning.
