Introduction
The Dreame X50 Ultra Blanca and the Mova E40 Ultra represent two robot vacuum proposals launched in 2025 that share a common denominator: both belong to the same parent company's ecosystem, although aimed at slightly different segments. The X50 Ultra is positioned as Dreame's flagship, whilst the E40 Ultra under the Mova brand offers solid performance with some technical simplifications.
Both models feature a complete multifunction base, capable of vacuuming and mopping with rotating mops that wash and dry automatically. They're designed for homes seeking total automation of the cleaning process, although with important nuances in terms of navigation technology, battery capacity and intelligent functions that mark notable differences in daily use.
Power and Suction
The 1,000 Pa difference in suction power favours the Dreame X50 Ultra Blanca with its 20,000 Pa, compared to the 19,000 Pa of the Mova E40 Ultra. In practice, this advantage can be particularly noticeable on medium-pile carpets or when there's accumulated ingrained dirt.
More relevant is the brushing system. The X50 Ultra integrates the dual HyperStream brush, a design that drastically reduces hair tangles by featuring two brushes anchored at one end. The E40 Ultra mounts a traditional single brush, which means a greater likelihood of tangles if there are pets at home or people with long hair.
The Dreame's main brush can be lifted during mopping, preventing it from getting unnecessarily wet and improving results on hard floors. This function isn't present on the Mova. The same applies to the side brush: the X50 Ultra lifts it when mopping and also features extension to better reach corners, whilst the E40 Ultra maintains a fixed side brush without extension capability.
Both models include an anti-tangle side brush, which helps reduce maintenance in this critical area.
Mopping
Both robots mop with two rotating mops and feature edge extension through the lateral movement system that improves coverage in areas close to skirting boards. Mop lifting reaches 10.5 mm in both cases, sufficient to traverse medium-thickness carpets without wetting them.
Substantial differences appear here. The Dreame X50 Ultra Blanca washes the mops with hot water, which notably improves the removal of grease and adhered dirt. The Mova E40 Ultra uses cold water for mop washing, less effective against difficult stains. Both dry with hot air, which helps prevent bad odours.
The X50 Ultra can automatically remove the mops at the base when only vacuuming is desired, avoiding unnecessarily carrying dry mops dragging along. This capability doesn't exist on the E40 Ultra, which requires manual intervention to remove the mops if we only want to vacuum.
Dirt detection marks another important difference. The Dreame model detects both dirt on the mops themselves and on the floor, adjusting the washing and scrubbing process according to need. The Mova lacks these functions, always performing the same standard cycle without intelligent adaptation.
Navigation System
The Dreame X50 Ultra Blanca incorporates a retractable LiDAR system combined with dual AI camera, capable of recognising up to 200 different types of obstacles. This includes curtain detection, pet recognition and remote access to the camera for home surveillance. It also features LED night vision for correct navigation in low-light conditions.
The Mova E40 Ultra mounts a traditional 3D LiDAR turret and front 3D laser sensor, but doesn't integrate a camera. It recognises pets and obstacles through sensors, although without specifying the exact number of identifiable objects. It doesn't offer curtain detection, remote camera access or front LED lighting.
The processor also differs: the X50 Ultra equips the AI Sage 13.0 Octa-core, whilst the E40 Ultra doesn't specify its CPU. Both include the CleanGenius AI system for intelligent cleaning, although the Dreame adds specific stain recognition through AI to intensify cleaning in specific areas.
Autonomy and Battery
Battery capacity clearly favours the Dreame X50 Ultra Blanca with 6,400 mAh compared to the 5,200 mAh of the Mova E40 Ultra. However, the declared autonomy is curiously superior on the E40 Ultra: 210 minutes against 180 minutes of the X50 Ultra.
This apparent contradiction is explained by the higher energy consumption of the Dreame model, derived from its superior suction power, dual brush, AI cameras and more powerful processor. In large homes, the X50 Ultra's greater battery capacity can translate into more complete cleaning cycles without the need for intermediate recharges, especially when intense vacuuming is combined with mopping.
Intelligent Functions
The Dreame X50 Ultra Blanca can overcome simple steps thanks to its lifting system, although the exact height isn't specified. The Mova E40 Ultra overcomes obstacles up to 20 mm, a useful capability for moving between rooms with small level changes or thick carpets.
Only the X50 Ultra integrates a proprietary voice assistant, allowing control through commands without depending exclusively on external assistants. Both models are compatible with Alexa and Google Home for integration into home automation ecosystems.
Multifunction Cleaning Base
Both bases feature auto-emptying of the dust container into 3.2-litre bags and clean water tanks of 4.5 litres and dirty water of 4 litres. The base dimensions are identical: 340 mm wide, 590.5 mm high and 456.7 mm deep.
Differences appear in advanced functions. The Dreame X50 Ultra Blanca incorporates third-generation washing tray self-cleaning, which keeps the base itself hygienic without manual intervention. The E40 Ultra lacks this function, requiring periodic manual cleaning of the tray.
UV disinfection is only present on the X50 Ultra, adding an extra layer of hygiene during the mop washing and drying process. The detergent tank comes integrated on the Dreame, whilst on the Mova E40 Ultra it's optional and must be purchased separately.
The X50 Ultra offers a plumbing connection kit that's purchased separately, allowing continuous water supply and automatic drainage for those seeking absolute automation. This option doesn't exist for the E40 Ultra.
Dimensions
The diameter is identical on both: 350 mm. The difference is in height: the Dreame X50 Ultra Blanca measures 89 mm, whilst the Mova E40 Ultra reaches 97 mm. Those 8 mm of difference can be decisive for passing under low furniture, sofas or beds with little ground clearance.
The weight and exact measurements of the bases coincide, occupying the same space in the home. The reduced height of the X50 Ultra favours its access to more areas of the home without getting blocked.
Real-World Usage Experience
For homes with pets, the Dreame X50 Ultra's dual HyperStream brush marks a notable difference in daily maintenance. The ability to lift brushes during mopping and automatically remove the mops simplifies everyday use, especially in homes that alternate between vacuuming only and mopping according to need.
The X50 Ultra's hot water mop washing and dirt detection are particularly useful in kitchens or high-traffic areas where difficult stains accumulate. The E40 Ultra, with cold water, requires greater frequency of manual mop cleaning to maintain optimal results.
The Dreame's dual AI camera provides peace of mind in homes with children or pets, allowing remote supervision and more precise navigation around delicate objects. The Mova E40 Ultra relies exclusively on sensors, sufficient for basic navigation but less adaptable to complex environments.
In homes with low furniture, the X50 Ultra's 89 mm height allows access to spaces where the E40 Ultra with its 97 mm would be blocked. This difference can mean cleaning or not under beds, sofas or certain types of furniture.
Conclusion: Which to Choose?
Choose the Dreame X50 Ultra Blanca if: You're seeking maximum automation with automatic mop removal, hot water washing and complete base self-cleaning. If you have pets and need a superior anti-tangle brushing system. For homes with low furniture where the 89 mm height makes the difference. If you value remote camera access, advanced obstacle detection and intelligent dirt recognition. In large homes where the 6,400 mAh battery guarantees complete cycles without intermediate recharges.
Choose the Mova E40 Ultra if: You prioritise a complete vacuuming and mopping solution with multifunction base at a more contained cost. For homes without height restrictions under furniture. If you don't need an integrated camera or advanced AI functions. In homes where the 210-minute autonomy perfectly covers the surface without requiring extreme power. When cold water mop washing is sufficient for your usual type of dirt and you don't mind performing some additional manual maintenance tasks on the base.
