Introduction
The Mova E40 Ultra, Dreame L10s Ultra Gen 2, and Mova P50 Ultra represent three compelling options in the current robot vacuum landscape. The E40 Ultra and P50 Ultra arrive as 2025 releases from Mova, whilst the Dreame L10s Ultra Gen 2 launched in 2024. All three feature multifunction bases with mop washing and drying capabilities, making them suitable for homes where automated floor maintenance matters.
These models share a similar design philosophy with rotating twin mops and LiDAR navigation. The differences emerge in suction power, advanced features, and how their bases are configured. Understanding these distinctions helps match each model to specific household needs, whether that's dealing with pet hair, maximising edge cleaning, or fitting the base into tighter spaces.
Differences at a Glance
- The Mova E40 Ultra and P50 Ultra deliver 19,000 Pa suction versus 10,000 Pa on the Dreame L10s Ultra Gen 2
- Only the P50 Ultra features an extendable side brush for improved corner cleaning
- The P50 Ultra lifts both its main brush and side brush during mopping, unlike the other two
- Dreame L10s Ultra Gen 2 includes a built-in detergent dispenser; the Mova models offer it as an optional extra
- The P50 Ultra adds third-generation automatic tray cleaning in its base
- Pet recognition works on the E40 Ultra and Dreame model but not the P50 Ultra
- Curtain detection appears exclusively on the P50 Ultra
- The P50 Ultra clears 22 mm obstacles compared to 20 mm on the others
- Base dimensions differ significantly: the P50 Ultra is wider but shorter than the E40 Ultra and Dreame
- A plumbing connection kit can be purchased separately for the Dreame L10s Ultra Gen 2
Suction Power and Brushwork
Suction power separates these models noticeably. The Mova E40 Ultra and P50 Ultra both generate 19,000 Pa, nearly double the 10,000 Pa from the Dreame L10s Ultra Gen 2. In practical terms, this matters when dealing with embedded dirt in carpets or pet hair that's worked itself into textile fibres. The higher figure doesn't guarantee better cleaning in every scenario, but it provides headroom for tougher jobs.
All three use a simplified main brush design, which typically reduces hair tangles compared to traditional bristle rollers. The E40 Ultra and Dreame keep their main brushes fixed during mopping, whilst the P50 Ultra lifts its main roller when the mops are down. This prevents the brush from interfering with the mopping action and avoids dragging a wet roller across floors.
The side brush setup reveals another distinction. The P50 Ultra extends its side brush outward to reach deeper into corners and lifts it during wet cleaning. The E40 Ultra and Dreame models keep their side brushes at a fixed position and height. Both Mova robots feature anti-tangle side brushes, which should help in homes with long hair or pet fur. The Dreame lacks this feature, so occasional manual cleaning of the side brush becomes more likely.
Mopping System
Each robot employs twin rotating mops that extend outward to tackle edges, using a movement Dreame calls Roboswing. This swivelling action helps the mops reach closer to skirting boards and furniture legs. All three lift their mops by 10.5 mm when crossing carpets or rugs, though the P50 Ultra's 10.5 mm figure still applies despite its other upgrades.
Water temperature for floor mopping remains cold across the board. The bases wash the mops with hot water and dry them with warm air, which aids hygiene and prevents musty smells. None of these models automatically detach their mops at the base for vacuum-only sessions, nor do they detect dirt levels on the mops or floor to trigger extra passes.
The mopping experience should feel similar day-to-day, since the core mechanism and lift height match. The P50 Ultra's brush elevation might keep floors slightly drier during mopping, but the fundamental approach to wet cleaning doesn't vary much between the three.
Navigation and Intelligence
LiDAR towers top all three robots, providing room mapping and efficient route planning. Each model supplements this with a front-facing 3D laser sensor for obstacle detection. No cameras appear on any of these robots, so visual object recognition and remote viewing aren't available.
Pet recognition works on the Mova E40 Ultra and Dreame L10s Ultra Gen 2, allowing the robots to identify and navigate around animals. The P50 Ultra drops this feature but adds curtain detection instead, which helps the robot avoid getting tangled in hanging fabric. Neither the E40 Ultra nor the Dreame model recognise curtains.
All three run CleanGenius AI for intelligent cleaning routines, adjusting suction and water flow based on room type or dirt levels detected through other sensors. Without cameras or LED lighting, these robots rely purely on laser-based navigation and proximity sensors to move around. This keeps things straightforward but removes the option to check in via video when away from home.
Battery Life and Coverage
Battery capacity sits at 5,200 mAh for all three models. The Mova E40 Ultra runs for 210 minutes on a single charge, whilst the Dreame L10s Ultra Gen 2 extends that to 240 minutes. Mova hasn't specified runtime for the P50 Ultra, though the identical battery suggests it falls somewhere in that range.
The extra half-hour on the Dreame model could matter in larger homes where the robot needs to cover more ground before returning to recharge. In most typical properties, either figure provides enough stamina to complete a full clean without interruption. None of the manufacturers list a maximum recommended floor area, so gauging coverage relies on these runtime figures and the efficiency of the navigation system.
Smart Features
Obstacle-climbing ability varies slightly. The Mova E40 Ultra and Dreame L10s Ultra Gen 2 manage 20 mm thresholds, whilst the P50 Ultra handles 22 mm. That extra couple of millimetres can make the difference between smoothly crossing a door strip or getting stuck, though most standard thresholds fall within the 20 mm range anyway.
None of these robots include a robotic arm or proprietary voice assistant. They do integrate with Alexa and Google Home, allowing voice commands through existing smart home setups. This keeps the design simpler and avoids adding another voice platform into the mix.
Multifunction Base
All three bases handle auto-emptying of the dust bin, mop washing with hot water, and warm-air mop drying. The dust bags hold 3.2 litres, which typically lasts several weeks before needing replacement. Clean water tanks measure 4.5 litres on the E40 Ultra and Dreame, dropping to 4 litres on the P50 Ultra. Dirty water capacity is 4 litres for the first two and 3.5 litres for the P50 Ultra.
The P50 Ultra introduces third-generation automatic tray cleaning, which keeps the washing area inside the base fresher without manual scrubbing. The E40 Ultra and Dreame lack this self-cleaning tray function, so occasional maintenance of the base interior becomes necessary.
Detergent dispensing comes built into the Dreame L10s Ultra Gen 2, adding cleaning solution during mop washing. The Mova E40 Ultra and P50 Ultra list this as an optional extra, meaning it's available but requires purchasing separately. For those who prefer just water, this distinction won't matter much.
A plumbing connection kit exists for the Dreame L10s Ultra Gen 2, allowing direct water supply and drainage. This removes the need to refill and empty tanks manually, though it does require installation and isn't included as standard. Neither Mova model offers this option, even as an add-on.
Physical Dimensions
The robots themselves measure identically: 350 mm diameter and 97 mm tall. This height allows them to slip under most furniture, though anything lower than 10 cm will remain out of reach.
Base dimensions tell a different story. The Mova E40 Ultra and Dreame L10s Ultra Gen 2 share the same footprint at 340 mm wide, 590.5 mm tall, and 456.7 mm deep. The P50 Ultra's base spreads wider to 420 mm but stands shorter at 470 mm, with a depth of 458 mm. The taller, narrower profile of the E40 Ultra and Dreame might suit corners or alcoves better, whilst the P50 Ultra's squatter stance could fit under shelving or counters where vertical space is limited.
Real-World Use
For homes with pets, the higher suction on the E40 Ultra and P50 Ultra helps pull embedded fur from carpets and rugs. The anti-tangle side brushes on both Mova models reduce the frequency of manual cleaning, which matters when dealing with long hair. The Dreame's lower suction and lack of anti-tangle side brush might struggle more in these situations, though its longer runtime could compensate in larger spaces.
The P50 Ultra's extendable side brush and brush elevation during mopping make it particularly effective for thorough edge cleaning and keeping floors drier during wet passes. Homes with lots of skirting board or furniture edges benefit from that extra reach. The automatic tray cleaning in its base also reduces maintenance effort, appealing to anyone who wants minimal hands-on involvement.
The Dreame L10s Ultra Gen 2 suits those who value runtime and the option to add plumbing connectivity. Its built-in detergent dispenser saves purchasing an optional accessory, and the longer battery life handles expansive floor plans more comfortably. The lower suction might not matter much on hard floors, where pickup demands are less intense.
All three handle hard floors, parquet, and low-pile carpets effectively. The mop lift height prevents soaking rugs during cleaning cycles, and the multifunction bases ensure mops stay fresh between uses. None of these models feel limited to small flats; the combination of decent battery capacity and efficient navigation makes them viable for medium to large homes.
Conclusion: Which One to Choose?
Choose the Mova E40 Ultra if you want strong suction and anti-tangle side brushes without needing the extra features of the P50 Ultra. It delivers solid performance at what's likely a more accessible price point, making it a sensible choice for homes with pets or mixed flooring where power matters but advanced edge cleaning isn't a priority.
Choose the Dreame L10s Ultra Gen 2 if extended runtime and the option for plumbing connectivity appeal to you. The built-in detergent dispenser and longer battery life make it practical for larger properties, and the available plumbing kit removes tank-filling chores entirely if you're willing to set it up. Lower suction won't be a dealbreaker on predominantly hard floors.
Choose the Mova P50 Ultra if you want the most advanced feature set Mova offers. The extendable side brush, brush elevation during mopping, automatic base tray cleaning, and slightly better obstacle clearance make it the top-tier option for anyone seeking thorough edge performance and reduced maintenance. The wider but shorter base also fits different spaces compared to the other two models.
