Introduction
The Mova E40 Ultra represents the latest 2025 entry from Dreame's secondary brand, whilst the Roborock Qrevo Edge S5A arrived in 2024 as part of Roborock's well-established premium range. Both models feature multifunctional bases that handle self-emptying, mop washing, and hot air drying, making them suitable for users seeking a largely hands-off cleaning experience. The E40 Ultra pushes suction power slightly higher at 19,000 Pa compared to the Qrevo Edge's 18,500 Pa, and offers longer runtime. The Roborock counters with its DuoDivide anti-tangle brush system and hot water mop washing, plus dirt detection technology that can trigger automatic re-cleaning. These are comprehensive solutions designed for medium to large homes where both vacuuming and mopping need to happen with minimal intervention.
Power and Vacuuming
Suction performance sits very close, with the Mova E40 Ultra rated at 19,000 Pa and the Roborock Qrevo Edge S5A at 18,500 Pa. In everyday use, that 500 Pa difference is unlikely to be perceptible, though the slight edge might help on high-pile rugs or when dealing with ground-in debris.
The main brush design is where things diverge more noticeably. Roborock equips the Qrevo Edge with its DuoDivide system, which channels hair towards the central suction inlet to reduce tangling. Mova opts for a simpler anti-tangle brush without the dual-roller configuration. Both approaches aim to minimise hair wrap, but the DuoDivide has proven particularly effective in homes with long-haired occupants or shedding pets.
Neither model raises its main roller during mopping, so carpets need to be flagged in the app to avoid wetting them. The side brushes are both anti-tangle designs, yet only the Roborock extends outward to sweep closer into corners. This extendable arm can make a tangible difference along skirting boards and in room edges where dust accumulates. Mova's side brush remains fixed, which is perfectly adequate for general cleaning but less thorough in tight spots. Neither side brush lifts when mopping commences.
Mopping
Both robots deploy twin rotating mop pads that spin to scrub floors rather than simply dragging a damp cloth. The Mova E40 Ultra extends its mops using a Roboswing motion, a hip-swivel movement that nudges the pad slightly under furniture overhangs and along edges. The Roborock Qrevo Edge S5A also extends its mops but without the swivel action, relying instead on straightforward lateral reach.
Mop lift is almost identical: 10.5 mm on the E40 Ultra and 10 mm on the Qrevo Edge. That half-millimetre won't matter in practice; both clear short-pile rugs and raised thresholds comfortably. What does matter is how the base treats those mops once they return. Roborock washes them with hot water, which helps dissolve grease and sanitise the fabric more effectively than cold. Mova uses cold water only. After washing, both bases dry the pads with hot air to prevent mildew and odours.
The Qrevo Edge S5A adds a self-cleaning cycle for its own wash tray, version 2.0 of Roborock's system, so the basin that rinses the mops also gets rinsed automatically. The Mova E40 Ultra lacks this feature, meaning the tray may need occasional manual attention to avoid residue build-up. Neither robot can detach its mops automatically at the base to switch into vacuum-only mode; you'll need to remove them by hand if you want pure suction on carpets.
Dirt detection is exclusive to the Roborock. Sensors monitor both the mop pads and the floor surface, triggering additional passes or re-washing when grime levels are high. This adaptive behaviour can be especially useful in kitchens or high-traffic hallways. The Mova follows its programmed routine without adjusting for visible dirt.
Navigation System
Both models navigate using a 360-degree LiDAR turret that maps rooms accurately and plans efficient routes. Obstacle avoidance is standard on each, preventing collisions with furniture legs and stray objects.
The Mova E40 Ultra includes a frontal 3D laser sensor, which adds another layer of precision when detecting low-lying or unusual obstacles. It also recognises pets specifically, allowing the robot to avoid startling animals or getting tangled in leads and toys. The Roborock Qrevo Edge S5A omits the 3D laser and pet recognition, relying on its LiDAR and general obstacle logic instead.
Neither machine carries a front-facing camera, so remote video access and AI-based object identification are absent. There's no LED illumination for night vision either. Intelligent cleaning routines are present on both: Mova calls its system CleanGenius, whilst Roborock uses SmartPlan 2.0. The Qrevo Edge runs on Roborock's RR Mason 11.0 algorithm; Mova's processor details aren't specified. In practical terms, both apps will suggest room-by-room schedules and adjust suction or water flow based on floor type, provided you've labelled surfaces correctly.
Battery and Runtime
Battery capacity is identical at 5,200 mAh, yet runtime diverges. The Mova E40 Ultra manages 210 minutes on a single charge, whilst the Roborock Qrevo Edge S5A lasts 180 minutes. That extra half-hour can be the difference between completing a large flat in one go or needing a mid-clean recharge, especially when mopping consumes more power than vacuuming alone.
Neither manufacturer lists charging times or maximum coverage area in the data provided, so direct comparisons on those fronts aren't possible. The longer runtime does suggest the E40 Ultra may suit sprawling layouts or multi-storey homes where the robot needs to travel further between rooms.
Smart Features
Both robots climb obstacles up to 20 mm, enough to mount typical door thresholds and transition strips without getting stuck. Neither includes a robotic arm for reaching into very tight spaces or manipulating objects, nor do they feature a built-in voice assistant. External voice control via Amazon Alexa or Google Home is supported on both, so you can start, stop, or dock the robot using voice commands through your existing smart speaker.
Multifunctional Base
Each base empties the robot's dust bin automatically into a larger bag: 3.2 litres on the Mova E40 Ultra and 2.7 litres on the Roborock Qrevo Edge S5A. The half-litre difference means slightly fewer bag changes over the course of a year, though in practice both will last several weeks in an average household before needing replacement.
Water reservoirs are similarly generous. The E40 Ultra holds 4.5 litres of clean water and 4 litres of dirty, whilst the Qrevo Edge stores 4 litres clean and 3.5 litres dirty. Larger tanks reduce refill frequency, particularly useful if you're mopping multiple rooms in one session.
Mova offers an optional detergent dispenser that you purchase separately, allowing the base to add cleaning solution during mop washing. Roborock does not provide a detergent tank at all, so you'd need to add solution manually to the clean-water reservoir if desired. Neither base includes UV disinfection, nor can either connect to household plumbing for continuous water supply, though no optional kit exists for that purpose either.
Dimensions
The robots themselves are nearly twins in size. The Mova E40 Ultra measures 350 mm in diameter and stands 97 mm tall; the Roborock Qrevo Edge S5A is 352 mm wide and 98 mm high. That single millimetre in height and two in diameter are functionally irrelevant. Both will slip under most sofas and beds with typical clearance.
Base footprints differ more noticeably. The E40 Ultra's dock is 340 mm wide, 590.5 mm tall, and 456.7 mm deep. The Qrevo Edge base shares the same 340 mm width but is shorter at 521 mm and deeper at 487 mm. Mova's taller, shallower profile may fit better against a wall in a narrow hallway, whilst Roborock's squatter, deeper design might tuck more easily under a countertop overhang. Consider your available floor space and any overhead obstructions when choosing where to site the dock.
Real-World Use
For homes with pets, the Roborock Qrevo Edge S5A's DuoDivide brush offers a clear advantage in managing hair, though the Mova E40 Ultra's longer runtime and dedicated pet recognition can help avoid disturbing animals during cleaning. If you have a large floor area, the E40 Ultra's extra 30 minutes of battery life and bigger dust bag reduce interruptions and maintenance frequency.
The Qrevo Edge's hot-water mop washing and dirt detection make it better suited to kitchens and high-traffic zones where sticky spills and ground-in grime are common. The automatic base-tray cleaning also means less hands-on maintenance over time. Mova's cold-water wash is adequate for light mopping on hard floors, and the Roboswing extension can help along skirting boards, but you may need to manually rinse the wash tray periodically.
Both robots handle hard floors, tiles, and sealed wood without issue. The 20 mm climb capability means standard thresholds pose no problem. If you want to add detergent to the mopping process, Mova's optional tank offers that convenience, though you'll need to purchase it separately. Roborock users would add solution directly to the clean-water reservoir instead.
In terms of navigation precision, the E40 Ultra's 3D laser sensor may prove helpful in cluttered rooms with low furniture or scattered toys, whilst the Qrevo Edge relies on its LiDAR and general obstacle logic, which works well in most scenarios but lacks the extra depth perception.
Conclusion: Which to Choose?
Choose the Mova E40 Ultra if you have a larger home that benefits from the extended 210-minute runtime, or if you want the option to add a detergent dispenser for automated cleaning-solution dosing. The 3D laser sensor and pet recognition are useful if you share your space with animals or have lots of low obstacles. The larger dust bag and water tanks mean fewer trips to empty and refill, which suits busy households.
Choose the Roborock Qrevo Edge S5A if you prioritise thorough mopping with hot-water mop washing and automatic base-tray self-cleaning, or if you deal with sticky kitchen spills that benefit from dirt detection and adaptive re-cleaning. The DuoDivide brush is particularly effective for long hair, and the extendable side brush improves corner coverage. Roborock's reputation for reliable hardware and polished app experience also counts in its favour, especially if you value brand track record.
Households with pets and large floor plans might lean towards the Mova for runtime and pet-specific features, whilst those prioritising mopping performance and low-maintenance operation will find the Roborock's hot-water wash, self-cleaning tray, and dirt sensors more compelling. Both represent capable, high-end solutions in the 2025 robot-vacuum landscape; the final choice hinges on whether you value extended autonomy and optional detergent dispensing, or superior mopping technology and adaptive cleaning intelligence.
