Introduction
The Mova P50 Pro Ultra, the Dreame X40 Ultra and the Dreame X50 Ultra Blanca represent three generations of high-end robot vacuum cleaners with multifunctional base stations. The first arrived in 2025 as Mova's response to the competition, whilst the X40 Ultra debuted in 2024 and the X50 Ultra Blanca closed 2025 as Dreame's most advanced offering. All three share design philosophy and similar features, but the technical differences mark out distinct usage profiles.
These models are designed for users seeking complete automation of mopping and vacuuming, with base stations that wash and dry the mops without manual intervention. Suction power varies notably between them, which directly affects performance on carpets and in homes with pets.
Power and Suction
Suction power draws a clear hierarchy. The Dreame X50 Ultra Blanca leads with 20,000 Pa, followed very closely by the Mova P50 Pro Ultra with 19,000 Pa. The Dreame X40 Ultra remains at 12,000 Pa, a figure that may prove insufficient for high-pile carpets or significant dirt accumulation. In practice, that 8,000 Pa difference between the X40 Ultra and the X50 Ultra is particularly noticeable on textile surfaces and when there's tangled pet hair.
The brushing system presents interesting variations. The P50 Pro Ultra features a TriCut 3.0, a design that combines bristles with blades to reduce hair tangles. The X40 Ultra is equipped with a simple brush, whilst the X50 Ultra opts for a dual brush that promises better debris capture. All three models raise the main brush during mopping, preventing it from getting wet and losing effectiveness.
All feature an extendable and liftable side brush, a characteristic that improves corner cleaning and protects the brush when only mopping. The anti-tangle system is present on all three, facilitating maintenance.
Mopping
The mopping system is practically identical on all three robots. They use two rotating mops with edge extension and Roboswing movement, which allows the robot to perform a slight turn to get the mop under furniture and overhangs. Mop lift reaches 10.5 mm in all cases, sufficient to pass over thin carpets without wetting them.
None incorporates hot water for mopping the floor, maintaining cold water during the process. All three will automatically remove the mops at the base station when only vacuuming is programmed, and detect dirt both on the mops and on the floor to adjust cleaning intensity.
The base stations wash the mops with hot water and dry them with hot air, accelerating the process and reducing the appearance of bad odours. The Mova P50 Pro Ultra and the Dreame X50 Ultra Blanca incorporate third-generation tray self-cleaning, whilst the X40 Ultra features the second generation. This difference implies greater efficiency in cleaning the washing tray itself.
Navigation System
The Dreame X50 Ultra Blanca introduces a retractable LiDAR that reduces the robot's total height to 89 mm, allowing it to slip under furniture where the other two cannot enter. The Mova P50 Pro Ultra and the Dreame X40 Ultra maintain fixed LiDAR turret, raising their height to 103.8 mm and 97 mm respectively.
Object recognition capability scales considerably. The X50 Ultra identifies up to 200 different obstacles, the P50 Pro Ultra reaches 160 and the X40 Ultra remains at 120. This translates to better avoidance of cables, toys, socks and other everyday objects. All three recognise pets, detect curtains to avoid tangles and feature LED for night vision.
The processor and algorithm also evolve. The X40 Ultra runs on AI Sage 11.0, whilst the X50 Ultra jumps to AI Sage 13.0. The P50 Pro Ultra does not specify the exact processor. All allow remote access to the camera for home surveillance.
Autonomy and Battery
The Dreame X40 Ultra and the X50 Ultra share a 6,400 mAh battery, compared to the Mova P50 Pro Ultra's 5,200 mAh. However, the declared autonomy does not follow that proportion: the P50 Pro Ultra reaches 210 minutes, the X40 Ultra 194 minutes and the X50 Ultra 180 minutes. The X50 Ultra's greater suction power explains why, despite having more battery, it offers less autonomy.
For medium or large-sized homes, any of the three completes cleaning without problems. In very large houses, the P50 Pro Ultra may require fewer intermediate recharges thanks to those 30 extra minutes of autonomy compared to the X50 Ultra.
Smart Functions
All three robots overcome obstacles of 22 mm in height, except the Dreame X50 Ultra Blanca which can handle single steps, a superior capability that allows it to negotiate more pronounced level changes between rooms. None incorporates a robotic arm.
The built-in voice assistant is present on the Mova P50 Pro Ultra and the Dreame X50 Ultra Blanca, allowing commands to be given directly to the robot without going through Alexa or Google Home. The X40 Ultra lacks this function, although it does support external assistants.
Multifunctional Cleaning Base Station
All three base stations auto-empty the dust bin, wash and dry the mops, and include a detergent tank. The dust bag has a capacity of 3.2 litres on all models. Differences appear in the water tanks: the P50 Pro Ultra features 4 litres of clean water and 3.5 of dirty water, whilst the X40 Ultra and X50 Ultra increase to 4.5 litres of clean water and 4 of dirty water.
The Dreame X50 Ultra Blanca is the only one that incorporates UV disinfection in the base station, adding an extra sanitisation step after washing the mops. This function may prove interesting in homes with young children or allergy sufferers.
The Dreame X40 Ultra and the X50 Ultra support a plumbing connection kit, which is purchased separately and allows the base station to be fed directly from the water supply. The P50 Pro Ultra does not offer this option.
Dimensions
The robot's height is crucial for accessing under furniture. The Dreame X50 Ultra Blanca, at 89 mm, slips under beds and sofas where the X40 Ultra (97 mm) and especially the P50 Pro Ultra (103.8 mm) cannot reach. All three share a diameter of 350 mm.
The base stations present different configurations. The Mova P50 Pro Ultra is wider (420 mm compared to 340 mm) but lower (470 mm compared to 590.5 mm). This can facilitate its placement under worktops or low shelving, although it occupies more horizontal space. The robot's tanks also vary: the X50 Ultra features 395 ml for dust, whilst the P50 Pro Ultra and X40 Ultra remain at 300 ml. The robot's water tank is 80 ml on all three.
Real-World Usage Experience
In homes with pets, the Dreame X50 Ultra Blanca and the Mova P50 Pro Ultra offer a clear advantage due to their greater suction power. The X50 Ultra's dual brush and the P50 Pro Ultra's TriCut 3.0 manage tangled hair better than the X40 Ultra's simple brush.
For houses with lots of low furniture, the X50 Ultra becomes the most practical option thanks to its reduced height. In large spaces where autonomy matters, the P50 Pro Ultra performs better with its 210 minutes of continuous operation.
The X50 Ultra's expanded object recognition reduces manual interventions in homes with children or cluttered environments. UV disinfection adds peace of mind in environments where hygiene is a priority.
Conclusion: Which to Choose?
Choose the Mova P50 Pro Ultra if you're seeking the greatest possible autonomy, you value having an integrated voice assistant and you need a base station that occupies less height. Its 19,000 Pa power is sufficient for most situations and its price may prove more competitive than the X50 Ultra's.
Choose the Dreame X40 Ultra if your budget is more limited and you don't need maximum suction power. It works well in homes without thick carpets or long-haired pets. The 12,000 Pa is sufficient for hard floors and thin carpets.
Choose the Dreame X50 Ultra Blanca if you have low furniture and need the robot to access all corners, if you live with pets that shed a lot of hair, if maximum hygiene is a priority thanks to UV disinfection, or if you want the most advanced object recognition. The ability to overcome single steps and the AI Sage 13.0 processor make it the most technically complete option.
