Introduction
The Dreame X50 Ultra Blanca and the Mova Z50 Ultra arrive on the market in 2025 as two high-end proposals designed for those seeking to fully automate home cleaning. Both devices belong to manufacturers linked to each other, as Mova is a second brand of Dreame, which explains why they share design philosophy and numerous technical features.
These robots are not simple vacuum cleaners: they integrate advanced mopping systems with multifunctional bases that wash and dry the mops automatically, intelligent navigation with dual-lens cameras and 3D laser sensors, plus capabilities to overcome obstacles that go beyond the usual. The difference lies in the technical details that can make a difference to the daily user experience.
Power and Suction
Suction power marks a first difference: the Dreame X50 Ultra Blanca develops 20000 Pa in Turbo mode, whilst the Mova Z50 Ultra reaches 19000 Pa. In practice, this difference may be noticeable when vacuuming long-pile carpets or when ingrained dirt accumulates in tile joints.
The main brushing system presents different philosophies. The Dreame opts for a dual anti-tangle brush, designed to prevent long hairs and fibres from wrapping around the mechanism. The Mova integrates the TriCut 3.0 system, which combines bristles with blades that cut tangled hairs. Both brushes are liftable during mopping to prevent them from getting unnecessarily wet.
As for the side brush, both models coincide: they are extendable to better reach corners, liftable during mopping and feature anti-tangle design. This configuration is especially useful in homes with long-haired pets.
Mopping
Here we find the most substantial difference between both robots. The Dreame X50 Ultra Blanca uses two rotating mops with the 3.0 extension system and Roboswing technology, which allows the robot to perform a lateral movement to introduce the mop under furniture and overhangs. The Mova Z50 Ultra mounts a Track roller with 18N pressure and a mini side mop for edges.
Mop lifting also varies significantly. The Dreame manages to lift them up to 10.5 mm, which allows it to travel over medium-thickness carpets without wetting them. The Mova reaches 7 mm, sufficient for thin carpets but more limited on thick carpets.
Mop washing at the base is carried out with hot water in both cases: 80°C on the Dreame X50 Ultra Blanca and 75°C on the Mova Z50 Ultra. Those five additional degrees can help eliminate more difficult stains and better disinfect the mops. Drying is carried out at 45°C on both models, with hot air that accelerates the process and prevents bad odours.
An exclusive advantage of the Dreame is the possibility of leaving the mops at the base when you only want to vacuum. The Mova does not offer this function, which requires manually removing the mops if you prefer a vacuum-only session. Both detect dirt on the mops and on the floor to automatically adjust the cleaning process.
Navigation System
The Dreame X50 Ultra Blanca mounts a retractable LIDAR system that hides when not in use, contributing to its lower overall height. The Mova Z50 Ultra uses a visible LIDAR 3.0 turret, which partly explains its 111 mm height compared to the 89 mm of the Dreame.
Both devices integrate dual-lens cameras with artificial intelligence and front 3D laser sensor to detect obstacles in real time. The Dreame recognises up to 200 different objects, whilst the Mova identifies 160. This difference can translate into more precise navigation by the Dreame in complex environments with many small objects on the floor.
Both recognise pets, detect curtains to avoid tangling and allow remote access to the camera from the app. They also include night vision LED for cleaning in low-light conditions. The Dreame specifies that it uses the AI Sage 13.0 Octa-core processor, whilst the Mova does not detail its CPU in the available documentation.
Autonomy and Battery
Battery capacity is identical: 6400 mAh on both models. The Dreame X50 Ultra Blanca specifies an autonomy of 180 minutes, data that the Mova Z50 Ultra does not detail in its specifications. With that autonomy, the Dreame can cover large homes in a single session without the need for intermediate recharges.
In practice, this battery capacity is more than sufficient for flats of up to 200 square metres, even performing combined vacuuming and mopping sessions that consume more energy.
Smart Functions
The ability to overcome obstacles marks a very relevant difference. The Dreame X50 Ultra Blanca can overcome obstacles between 42 and 60 mm in height, an exceptional figure that allows it to pass over thick carpets, sliding door guides or pronounced level changes. The Mova Z50 Ultra is limited to 22 mm, sufficient for usual transitions but much more restrictive.
This can be especially noticeable in homes with high-pile carpets or with small steps between rooms. The Dreame will transit without problems through areas where the Mova could get stuck or give up entering.
Both robots integrate a simple voice assistant for control by basic commands, although neither mounts a robotic arm to manipulate objects.
Multifunctional Cleaning Base
The Dreame X50 Ultra Blanca base incorporates third-generation tray self-cleaning, a system that automatically washes the tray where the mops are cleaned to prevent dirt accumulation and bad odours. The Mova Z50 Ultra does not include this function, which will require periodic manual cleaning of the tray.
The Dreame adds UV disinfection at the base, absent on the Mova. This function complements hot water washing to eliminate bacteria from the mops. Both bases include detergent tank that is automatically dispensed during washing.
The dust bag has greater capacity on the Mova: 4 litres compared to 3.2 litres on the Dreame. The clean and dirty water tanks are identical: 4.5 litres and 4 litres respectively, sufficient for multiple mopping sessions without refilling.
The Dreame offers an optional plumbing connection kit that can be purchased separately, allowing the base to be connected directly to the water supply and drainage. The Mova does not have this option. It should be considered that this kit is an additional accessory, not included as standard.
Dimensions
The robot's height is determining for passing under furniture. The Dreame X50 Ultra Blanca measures 89 mm, whilst the Mova Z50 Ultra reaches 111 mm. Those 22 mm of difference can determine whether the robot accesses or not under sofas, low beds or kitchen furniture with little separation from the floor.
The diameter is identical on both: 350 mm, standard on high-end robots. The robot's dust container is larger on the Dreame (395 ml compared to 300 ml), although the Mova's water tank is superior: 160 ml with hot water compared to 80 ml on the Dreame.
The base dimensions vary slightly. The Dreame's measures 340 mm wide, 590.5 mm high and 456.7 mm deep. The Mova's is wider (390.4 mm) but less tall (545 mm), with a similar depth of 463.3 mm. This can influence the available location for the base in your home.
Real-World Experience
For large homes, the Dreame X50 Ultra Blanca offers clear advantages: greater specified autonomy (180 minutes), better ability to overcome obstacles and a mopping system with extension and Roboswing that better reaches corners and under furniture. Its lower height allows it to access areas where the Mova would be blocked.
In homes with pets, both robots are well equipped. The Dreame's dual anti-tangle brush may prove more effective with long hairs than the Mova's TriCut 3.0 system, although the latter also offers good performance. The Dreame's greater suction power (20000 Pa) helps extract hairs embedded in carpets.
Maintenance is more convenient with the Dreame thanks to tray self-cleaning and UV disinfection, which reduce manual tasks. The possibility of leaving the mops at the base for vacuum-only sessions adds flexibility to daily use.
The Mova Z50 Ultra stands out for its mopping system with roller and 18N pressure, effective for ingrained stains, and for a larger dust bag capacity that will space out changes. Its larger water tank on the robot can be advantageous in long mopping sessions without returning to the base.
Conclusion: Which to Choose?
Choose the Dreame X50 Ultra Blanca if you're looking for the most complete and versatile robot, especially for large homes or with complex layouts. Its ability to overcome obstacles up to 60 mm, the lower height that allows it to pass under low furniture, the mopping system with extension and Roboswing, tray self-cleaning and UV disinfection make it the most advanced option. It's ideal if you have long-haired pets, thick carpets or want to minimise manual maintenance. The possibility of purchasing the plumbing connection kit adds potential for total automation in the long term.
Choose the Mova Z50 Ultra if you prefer a mopping system with roller and 18N pressure, especially effective on very dirty floors or with difficult stains. Its greater dust bag capacity (4 litres) and water tank on the robot (160 ml) can be advantageous if you want to space out maintenance tasks. It's a solid option for homes without complicated obstacles or very low furniture, where its greater height does not pose a problem. It offers high-end features at a price that is usually more competitive than the Dreame, maintaining essential characteristics such as mop washing at 75°C, dual AI camera and detection of 160 objects.
