Introduction
The Mova E40 Ultra and Roborock Qrevo S5V represent two compelling approaches to automated home cleaning in 2025. Whilst the Roborock arrives from the world's leading robot vacuum manufacturer with proven reliability, the Mova—manufactured by Dreame under their secondary brand—offers aggressive specifications at a competitive price point. Both feature multifunctional bases capable of washing and hot-air drying mops, alongside auto-emptying dustbins, making them suitable for households seeking minimal maintenance. The key differences lie in suction power, navigation sensors, and dust capacity, which we'll explore in detail.
Suction Power and Brush Systems
The most striking difference here is raw suction: 19,000 Pa on the Mova E40 Ultra against 12,000 Pa on the Roborock Qrevo S5V. In practice, this translates to more aggressive pickup of embedded dirt in carpets and better performance on textured flooring. Households with pets or high foot traffic will notice the advantage when dealing with ground-in debris.
Where Roborock claws back ground is its DuoDivide anti-tangle brush. This dual-roller design channels hair towards the central suction inlet, dramatically reducing the frequency of manual brush cleaning. The Mova relies on a simpler brush design, though it does feature an anti-tangle side brush to minimise hair wrap around the perimeter sweeper.
Neither model lifts its main or side brush during mopping, so both sweep continuously even when wet-cleaning. The side brushes on each machine are anti-tangle variants, which helps when navigating around chair legs and furniture bases where hair tends to accumulate.
Mopping Performance
Both robots deploy twin rotating mops and lift them when crossing carpets—10.5 mm on the Mova, 10 mm on the Roborock. That extra half-millimetre is negligible in real-world use. What matters more is edge coverage. The Mova E40 Ultra incorporates RoboSwing, a hip-swivelling motion that nudges the mop slightly under furniture overhangs and skirting boards. The Roborock Qrevo S5V extends its mop to reach edges but lacks the lateral swing movement.
The bases on both machines wash mops with cold water and dry them with hot air, preventing bacterial growth and odours between cleaning sessions. Neither offers automatic mop removal for vacuum-only runs, so you'll need to detach the pads manually if you want pure suction without dragging damp cloths across the floor. Neither model detects dirt on mops or floors to trigger re-mopping, so cleaning thoroughness depends on your scheduled passes rather than adaptive intelligence.
One practical edge for the Mova: an optional detergent dispenser that can be purchased separately. The Roborock has no provision for automated detergent dosing, meaning you'd need to add cleaning solution manually to the clean-water tank if desired.
Navigation and Obstacle Avoidance
Both robots navigate using 360-degree LiDAR mounted in the top turret, ensuring accurate room mapping and efficient path planning. The Mova E40 Ultra adds a front-facing 3D laser sensor, which improves close-range object detection and helps avoid low-profile hazards like cables, shoes, and pet toys. The Roborock Qrevo S5V relies on LiDAR alone without supplementary 3D sensing.
Pet owners will appreciate the Mova's dedicated pet-recognition capability, which can identify animals and adjust behaviour accordingly—useful if you have a nervous cat or a dog that likes to follow the robot around. The Roborock does not offer this feature. Neither machine includes an AI camera, LED lighting for night vision, or remote video access, so visual monitoring isn't part of the package.
On the software side, the Mova employs CleanGenius AI for intelligent cleaning routines, whilst the Roborock uses SmartPlan 1.0. Both systems learn room layouts and optimise cleaning sequences, though Roborock's app ecosystem is widely regarded as more polished and responsive, benefiting from years of refinement.
Battery Life and Coverage
Battery capacity is identical at 5,200 mAh, yet the Mova E40 Ultra extracts 210 minutes of runtime compared to 180 minutes on the Roborock Qrevo S5V. The difference likely stems from motor efficiency and suction calibration. An extra half-hour matters in larger homes where the robot needs to cover multiple zones before returning to recharge. For typical two- or three-bedroom properties, either runtime will suffice, but sprawling open-plan layouts or multi-storey cleaning favour the Mova's endurance.
Smart Features
Both robots clear obstacles up to 20 mm high, which handles most door thresholds and low carpet edges without issue. Neither includes a robotic arm for picking up objects or a proprietary voice assistant, though both integrate with Alexa and Google Home for voice control. This is standard fare for 2025, and neither machine pushes boundaries in this department.
Multifunctional Base Station
The base stations handle auto-emptying, mop washing, and hot-air drying—core functions that define a multifunctional dock. The Mova E40 Ultra holds a 3.2-litre dust bag, 4.5 litres of clean water, and 4 litres of dirty water. The Roborock Qrevo S5V offers a 2.7-litre dust bag, 4 litres clean, and 3.5 litres dirty. In practical terms, the Mova requires slightly less frequent bag changes and water refills, which matters if you're running daily cleaning cycles in a busy household.
Neither base self-cleans its washing tray, includes UV disinfection, or supports plumbed water connections out of the box. No optional plumbing kit is available for either model, so manual refilling remains the only option. The Mova's optional detergent dispenser is a nice touch for those who want automated dosing, though it's an additional purchase rather than a standard inclusion.
Physical Dimensions
The robots are nearly identical in size: the Mova measures 350 mm in diameter and 97 mm tall, whilst the Roborock is 353 mm wide and 96.5 mm high. That half-millimetre height difference is irrelevant; both will squeeze under most sofas and bed frames with typical 100 mm clearance. The Mova's base is taller at 590.5 mm versus 521 mm for the Roborock, but narrower in depth (456.7 mm vs 487 mm), so consider your available floor space and whether vertical or horizontal footprint matters more in your intended location.
Real-World Use Scenarios
For homes with multiple pets, the Mova E40 Ultra's higher suction, longer runtime, and pet-recognition sensor make it the more capable choice, though the lack of an anti-tangle main brush means you'll still need to cut away hair periodically. The Roborock Qrevo S5V counters with its DuoDivide brush, which dramatically reduces maintenance if hair wrap is your primary concern.
In large properties, the Mova's 210-minute autonomy and larger water tanks reduce interruptions during extended cleaning sessions. The 3D laser sensor also helps in cluttered spaces with lots of floor-level obstacles. Smaller flats and tidy homes won't notice the runtime difference, and Roborock's refined app experience and brand reputation may carry more weight.
If you value minimal intervention, the Mova's larger dustbag and water reservoirs mean fewer trips to empty and refill. The optional detergent dispenser adds convenience for those who prefer automated dosing. The Roborock's smaller capacities are still generous, but high-frequency users will notice the difference over a month of daily cleaning.
Conclusion: Which Should You Choose?
Choose the Mova E40 Ultra if you need maximum suction power for deep-pile carpets or embedded dirt, have pets that shed heavily and want recognition features, or live in a larger home where extended runtime and bigger water tanks reduce maintenance frequency. The 3D laser sensor and RoboSwing mopping are useful bonuses for cluttered spaces and thorough edge cleaning.
Choose the Roborock Qrevo S5V if you prioritise minimal brush maintenance thanks to the DuoDivide anti-tangle system, prefer a proven brand with a polished app ecosystem, or have a compact home where the smaller base footprint and shorter runtime are perfectly adequate. Roborock's reliability and customer support network make it a safer bet for those who value long-term peace of mind over headline specifications.
