Introduction
The Dreame L50 Ultra AE, the Roborock Qrevo Edge 2 and the Roborock Qrevo Edge S5A represent three distinct approaches within the robot vacuum segment with multifunction base. The Dreame model, launched in 2026, focuses on raw power with 28,000 Pa of suction and a mop washing system at 100°C. The Qrevo Edge 2, also from 2026, stands out for its advanced navigation technology with AI camera and a mopping system with warm water. The Qrevo Edge S5A, from the previous year, offers a more accessible solution whilst maintaining solid mopping and battery performance.
We're talking about devices designed for users seeking complete automation of floor maintenance, with bases that not only empty dust, but also wash and dry the mops after each use. The choice between them will depend on the weight you give to suction power, artificial intelligence or the relationship between features and price.
Power and Suction
Suction power marks notable differences. The Dreame L50 Ultra AE leads with 28,000 Pa, a figure that exceeds the Qrevo Edge 2 by 3,000 Pa and almost doubles the S5A's 18,500 Pa. In practice, this translates into better performance on carpets and in picking up particles embedded in tile joints.
The brushing system shows different philosophies. The Dreame mounts a TriCut 3.0 brush that combines bristles with blades to cut tangled hair, whilst both Roborock models use the DuoDivide Antienredos, which pushes hair towards the central gap to facilitate suction. Both approaches work well with pets, although the DuoDivide design tends to require less manual maintenance.
All three devices incorporate an extendable, anti-tangle side brush. An exclusive advantage of the Dreame L50 Ultra AE and the Qrevo Edge 2 is the lifting of the main brush during mopping, preventing it from getting wet and facilitating the cleaning of hard floors without dragging wet residue.
Mopping
The mopping system presents important variations. The Qrevo Edge 2 spins its mops at 230 RPM with a pressure of 8N, exceeding the S5A's 200 RPM and the Dreame's 180 RPM. However, the Dreame model compensates with its RoboSwing system, which performs a lateral movement to introduce the mops under protrusions and low furniture.
Mop lifting reaches 12 mm on the Qrevo Edge 2, allowing it to travel over medium-pile carpets without wetting them. The Dreame stays at 10.5 mm and the S5A at 10 mm, differences that may matter if you have thick carpets at home.
The Qrevo Edge 2's warm water mopping improves the dissolution of grease and adhered dirt, something the other two models don't offer as they use cold water. Additionally, the Edge 2 and the S5A detect dirt both on the mops and on the floor, automatically going over particularly dirty areas. The Dreame lacks these intelligent detection functions.
Automatic mop removal at the base appears on the Dreame and the Qrevo Edge 2, allowing the robot to vacuum without dragging the mops through areas that only need vacuuming. The S5A doesn't have this function, which means you have to remove the mops manually if you want to vacuum without mopping.
Navigation System
The Qrevo Edge 2 differs radically with its retractable LiDAR and front AI camera. This system recognises up to 280 different obstacles, identifies pets to avoid them carefully, detects curtains to avoid getting tangled and allows remote access to the camera from the app. The night vision LED facilitates navigation in dark rooms without needing to turn on lights.
The Dreame L50 Ultra AE mounts a conventional LiDAR turret with front 3D laser sensor, sufficient for precise mapping and avoiding basic obstacles, but without the visual recognition capability of the Edge 2. The Qrevo Edge S5A also uses a LiDAR turret but without a front 3D sensor or camera, relying on the laser and traditional sensors.
Artificial intelligence marks another gap. The Qrevo Edge 2 runs SmartPlan 3.0, which optimises routes according to the type of dirt detected and recognises stains for automatic re-mopping. The S5A has SmartPlan 2.0, less advanced but functional. The Dreame lacks these AI-based intelligent cleaning functions.
Autonomy and Battery
All three robots mount 5,200 mAh batteries. The Qrevo Edge 2 declares 188 minutes of autonomy, barely superior to the S5A's 180 minutes. The Dreame doesn't specify duration, although with the same battery capacity it should operate at similar figures.
In large homes, this autonomy allows covering between 200 and 250 m² in a single vacuuming cycle, sufficient for most households without needing intermediate recharges. Intelligent battery management means all three models return to the base when they detect low level and resume cleaning after recharging.
Smart Functions
The ability to overcome obstacles is identical: 20 mm in all three cases. This allows crossing door thresholds, thick carpets and small level changes without getting stuck.
The Qrevo Edge 2 incorporates its own voice assistant, allowing you to give it orders directly without going through Alexa or Google Home. All three models are compatible with external assistants, facilitating integration into home automation ecosystems.
Multifunction Cleaning Base
Mop washing clearly differentiates the models. The Dreame reaches 100°C, a temperature that eliminates bacteria and disinfects the mops more effectively. The Qrevo Edge 2 reaches 80°C and the S5A 75°C, equally effective temperatures but with lower sanitising capacity.
Hot air drying varies: 55°C on the Edge 2 compared to 45°C on the Dreame and the S5A. Faster drying reduces the risk of bad odours and bacteria proliferation on the mops.
Self-cleaning of the washing tray is third generation on the Dreame, compared to version 2.0 on the Roborock models. This means more complete cleaning cycles that reduce manual maintenance of the base.
The detergent tank appears only on the Dreame, dispensing product during mop washing to improve hygiene. The Roborock models do without this function. The Dreame's plumbing connection kit is sold separately, allowing automation of water filling and emptying, although it doesn't come as standard.
Dust bag capacity reaches 3.2 litres on the Dreame, superior to the Roborock models' 2.7 litres. Clean water tanks also favour the Dreame with 4.5 litres compared to 4 litres, and dirty water with 4 litres compared to 3.5 litres. These differences translate into lower frequency of manual emptying and filling.
Dimensions
The robot's height marks an important functional difference. The Qrevo Edge 2 measures only 79.8 mm, allowing it to slide under sofas, beds and low furniture where the other two can't reach. The Dreame reaches 97 mm and the S5A 98 mm, dimensions that may limit access to confined spaces.
Diameter varies minimally: 350 mm on the Dreame compared to 352 mm on the Roborock models. The Dreame's base is taller (590 mm compared to 521 mm) but less deep (457 mm compared to 487 mm), aspects to consider depending on the available space at home.
Real-world user experience
In homes with pets, the Qrevo Edge 2 offers clear advantages thanks to specific animal recognition and greater mopping power with warm water. The Dreame compensates with greater suction and mop washing temperature, useful for removing adhered hair and disinfecting. The S5A performs well but without the intelligent detection functions.
For large houses, all three models offer sufficient autonomy. The Dreame stands out for its larger tanks, reducing trips to the base to refill water or empty waste. The Edge 2 balances with its dirt detection system, which optimises water and battery consumption.
In homes with lots of low furniture, the Qrevo Edge 2's reduced height makes the difference. Its ability to slip under sofas and beds of 8 cm height expands the cleaned surface without manual intervention.
Daily maintenance is simpler with the Dreame thanks to its third-generation self-cleaning system and automatic mop removal. The Edge 2 compensates with dirt detection, which avoids wasting water and energy on already clean areas.
Conclusion: Which one to choose?
Choose the Dreame L50 Ultra AE if you're looking for maximum suction power and prioritise hygiene with mop washing at 100°C. It's ideal for large homes where the ample tanks reduce maintenance, and for users who value the detergent tank and the possibility of plumbing connection. The RoboSwing system improves mopping on edges, although it lacks the AI functions of the Edge 2.
Choose the Roborock Qrevo Edge 2 if you need the most advanced navigation on the market with visual recognition of 280 obstacles, pet detection and remote camera access. Its height of 79.8 mm allows cleaning under furniture inaccessible to other robots. Mopping with warm water and automatic dirt detection intelligently automate cleaning, although suction power falls below the Dreame.
Choose the Roborock Qrevo Edge S5A if you want solid vacuuming and mopping performance without needing the most advanced AI functions. It offers a good balance between price and performance, with mop washing at 75°C and SmartPlan 2.0. It's suitable for medium-sized homes without pets or very low furniture, where traditional navigation is sufficient and you don't need automatic mop removal.
