Introduction
This robot vacuum comparison pits three models representing the most advanced options on the current market. The Mova P50s Ultra arrives in 2025 as an innovative proposition from Dreame's second brand, with features that compete directly with sector benchmarks. Facing it, two options from the world's leading manufacturer: the Roborock Qrevo CurvX, also launched in 2025, and the Roborock Qrevo Edge S5A, from the previous year but still highly competitive.
All three incorporate complete multifunction bases that wash and dry the mops automatically, ensuring efficient mopping with minimal manual intervention. They're designed for medium-to-large homes seeking total autonomy, with special attention to pet-owning households thanks to their anti-tangle brush systems and intelligent navigation.
Power and Suction
The Mova P50s Ultra sets itself apart with its 24,000 Pa suction power, a figure that exceeds the Roborock Qrevo CurvX's 22,000 Pa and the Qrevo Edge S5A's 18,500 Pa. In practice, this difference is particularly noticeable on medium or long-pile carpets, where the Mova model extracts more embedded dirt.
The brushing system shows different philosophies. The P50s Ultra features Dreame's Doble Cepillo HyperStream, with two brushes anchored at one end that minimise long hair tangles. Both Roborock models mount the DuoDivide Antienredos, which pushes hairs towards the central gap to facilitate direct suction. Both approaches work well with pets, although the HyperStream design proves somewhat more effective when there's accumulated hair.
An exclusive advantage of the P50s Ultra is that both the main and side brushes can be raised during mopping. The Qrevo CurvX only raises the main brush, whilst the Qrevo Edge S5A doesn't lift either. This matters because it prevents the brushes from dragging wet dirt or staining already-mopped areas. All three models incorporate an extendable, anti-tangle side brush, useful for better capturing dirt in corners and along skirting boards.
Mopping
All feature a dual rotating mop system, but differences appear in the details. The Mova P50s Ultra includes mop extension with Roboswing movement, a lateral swing that allows better cleaning under furniture overhangs and edges. The Qrevo CurvX and Edge S5A also extend the mops, though without this additional movement.
Mop lift varies: the P50s Ultra reaches 10.5 mm, the Qrevo CurvX offers an adjustable range from 7 to 17 mm depending on the surface, and the Edge S5A remains at a fixed 10 mm. The CurvX's variable system provides versatility for carpets of different thicknesses.
A function only the P50s Ultra has is automatic mop removal at the base. When you only want to vacuum without mopping, the robot leaves the mops at the station and departs clean. The Roborock models keep the mops permanently installed, though they raise them to maximum height to avoid contact with the floor.
All three wash the mops with hot water at the base, a fundamental aspect for eliminating grease and bacteria. They also dry with hot air, reducing times and preventing bad odours. All detect dirt both on the mops and on the floor to re-clean areas that need it.
Navigation System
Here the differences are notable. The Mova P50s Ultra mounts the FlashPulse system with dual AI camera, front 3D laser sensor and LED for night vision. It recognises up to 200 different obstacle types, including pets and curtains, the latter a novelty that prevents the robot from tangling in hanging fabrics. It allows remote camera access to monitor the home from your mobile.
The Roborock Qrevo CurvX also integrates dual AI camera, 3D laser sensor and night LED, with remote camera access. Its database identifies 108 objects, sufficient for most homes though inferior to the P50s Ultra. It uses the RR Mason 11.0 algorithm, highly refined after years of development. The CurvX's great advantage is its retractable LiDAR, which hides when not navigating, allowing a height of just 79.8 mm.
The Roborock Qrevo Edge S5A dispenses with AI camera, 3D laser sensor and night LED. It also doesn't offer remote camera access because it simply doesn't have one. It maintains a traditional LiDAR turret, which explains its 98 mm height. For homes without pets or complicated objects, its navigation remains effective and precise.
Autonomy and Battery
The Mova P50s Ultra and Roborock Qrevo CurvX share a 6,400 mAh battery. The CurvX declares 220 minutes of autonomy, though the P50s Ultra doesn't specify this data in the table. The Qrevo Edge S5A mounts a 5,200 mAh battery with 180 minutes of autonomy.
In homes up to 250 m², any of the three completes cleaning without needing an intermediate recharge. For larger surfaces, the models with greater battery capacity offer an extra safety margin, especially if maximum power modes are activated that consume more energy.
Smart Functions
All three overcome simple thresholds, though with different capabilities. The P50s Ultra and Qrevo CurvX are prepared for simple thresholds without specifying exact height, whilst the Edge S5A clearly indicates 20 mm. This allows negotiating thick carpets, door guides or small level changes between rooms.
The Mova P50s Ultra and Roborock Qrevo CurvX incorporate their own voice assistant, in addition to compatibility with Alexa and Google Home. The Qrevo Edge S5A only supports external assistants. Having an integrated assistant makes it easier to give direct commands to the robot without depending on other devices, something practical when you're near the base.
Multifunction Cleaning Base
All three bases auto-empty the dust bin, wash the mops with hot water and dry them with hot air. Differences appear in additional functions and capacities.
The Mova P50s Ultra stands out with UV disinfection of the washing tray, unique amongst the three models. It also includes an integrated detergent tank, which dispenses product during mop washing to improve cleaning. Its tray self-cleaning system is third generation, the same as the Qrevo CurvX, whilst the Edge S5A mounts version 2.0, somewhat less advanced.
Regarding capacities, the P50s Ultra features the largest dust bag at 3.2 litres, compared to the CurvX's 2.5 litres and Edge S5A's 2.7 litres. All three share a 4-litre clean water tank, but the P50s Ultra and Edge S5A offer 3.5 litres of dirty water, half a litre more than the CurvX. For large homes, these differences can translate into fewer manual emptying and refilling operations.
Dimensions
The Roborock Qrevo CurvX is the lowest at 79.8 mm height thanks to its retractable LiDAR. This allows it to slip under low furniture where the other two cannot reach. The Mova P50s Ultra measures 82.5 mm, barely 3 mm more, whilst the Qrevo Edge S5A reaches 98 mm due to its traditional LiDAR turret.
In diameter all are around 350 mm, without relevant differences. The weight and base dimensions vary: the P50s Ultra's measures 420x470x458 mm, the CurvX's 450x450x450 mm (the most compact in cube form), and the Edge S5A's 340x521x487 mm (the narrowest but also the tallest). It's worth measuring the available space before deciding, especially if you're planning to install it under furniture or in a cupboard.
Real-World Usage Experience
For pet-owning homes, the Mova P50s Ultra offers the most complete combination: maximum suction power, specific animal recognition, HyperStream anti-tangle brush and UV tray disinfection. The Qrevo CurvX also works very well with pets thanks to its dual camera and DuoDivide system, though without UV disinfection.
If you have low furniture or sofas with little clearance, the Qrevo CurvX is the best option. Its 79.8 mm allows it to access spaces that remain out of reach for the other two. The Edge S5A, at 98 mm, is the least suitable for this scenario.
In large homes over 200 m², the greater battery capacity of the P50s Ultra and CurvX provides peace of mind. The P50s Ultra's 3.2-litre dust bag also reduces maintenance frequency. For smaller flats, the Edge S5A performs perfectly without paying for features you won't use.
The P50s Ultra's automatic mop removal function proves very practical if you alternate vacuum-only days with complete mopping days. The Roborock models require carrying the mops permanently attached, though raised.
Conclusion: Which to Choose?
