Introduction
This comparison brings together three 2025 models with different approaches within the high-end segment. The Mova P50 Pro Ultra and the Mova P50 Ultra share the same technical platform in many respects, but differ in the level of artificial intelligence and premium features. The Roborock QV 35S arrives as an alternative from an established brand, with a more classic approach to navigation and mopping.
Both Mova models offer very high suction power and third-generation multifunctional bases. The Roborock, without sacrificing advanced features, offers a more modest power proposition but backed by the experience of a world-leading brand. Each is designed for different user profiles: from those seeking maximum automation to those prioritising reliability and simplicity.
Power and Suction
The most obvious difference in this section lies in the numbers: both Mova units achieve 19,000 Pa of suction, almost double the Roborock QV 35S with its 10,000 Pa. In practice, this translates into greater capacity to lift embedded dust from carpets or drag heavier debris in a single pass. Homes with pets or long-pile carpets particularly benefit from this extra power.
The main brush marks another important difference. The Mova P50 Pro Ultra features the TriCut 3.0 system, which combines bristles with blades to cut tangled hair during brushing. Both the P50 Ultra and the Roborock QV 35S have simple silicone brush, easier to clean but without the active cutting system. For households with several pets, the TriCut 3.0 significantly reduces manual maintenance.
All three robots lift the main brush during mopping, but only the two Mova models also lift the side brush and feature extendable side brush. This improves cleaning in corners and edges without risk of splashing water with the brush spinning. The Roborock maintains the side brush fixed, which may slightly limit reach in tight corners.
Mopping
All three models employ a dual rotating mop system, washed at the base with hot water and dried with hot air. However, the differences in advanced features are notable. Both the P50 Pro Ultra and the P50 Ultra integrate mop extension with Roboswing movement, allowing better reach to edges and slightly inserting the mop under furniture overhangs. The Roborock QV 35S does not have mop extension.
Mop lift is practically identical: 10.5 mm on the Mova models, 10 mm on the Roborock. Sufficient to avoid wetting short-pile carpets, although thick carpets may require manual delimitation in the app. Where there is a difference is in automatic mop detachment: only the Mova P50 Pro Ultra can remove the mops at the base to perform vacuum-only sessions, without manual intervention. This is very convenient if you vacuum daily but mop only two or three times a week.
Dirt detection is exclusive to the P50 Pro Ultra. This model detects both dirt on the mops during washing and stains on the floor, automatically re-scrubbing or re-washing until the sensor confirms cleanliness. The P50 Ultra and the Roborock lack this function, performing standard washing and mopping cycles without automatic adaptation to the actual dirt level.
Navigation System
All three units employ LIDAR turret for mapping and navigation, guaranteeing precision in map creation and route planning. The difference lies in obstacle avoidance systems and intelligent recognition. The Mova P50 Pro Ultra incorporates dual AI camera, front 3D laser sensor, night vision LED and recognition of up to 160 different obstacles, including pets. Additionally, it allows remote camera access for surveillance from the app.
The Mova P50 Ultra maintains the 3D laser sensor and curtain detection, but eliminates the AI cameras, night LED and remote access. The number of recognised obstacles is not specified. The Roborock QV 35S dispenses with both cameras and 3D laser sensor, relying on its traditional obstacle avoidance system without specific recognition of pets or curtains.
In homes with young children, scattered toys or pets, the dual camera system of the P50 Pro Ultra offers a clear advantage. Specific pet recognition avoids chasing them or blocking their feeding bowls. Curtain detection on both Mova models prevents the robot from getting tangled, something that can occur with long curtains on the Roborock.
Battery Life and Battery
All three robots feature 5,200 mAh batteries, but declared battery life varies. The Mova P50 Pro Ultra achieves 210 minutes, the Roborock QV 35S reaches 180 minutes, and the P50 Ultra does not specify duration. The 30-minute difference between the P50 Pro Ultra and the Roborock can be decisive in large homes, allowing completion of extensive surfaces without intermediate recharges.
In practice, homes of up to 150-180 m² can be cleaned without problems with any of the three. For surfaces exceeding 200 m², the Mova P50 Pro Ultra offers greater safety margin. The self-emptying and mop-washing base allows the robot to resume automatically after recharging, but it is always preferable to complete cleaning in a single session for greater efficiency.
Smart Features
The ability to overcome obstacles is slightly superior on both Mova models: 22 mm versus 20 mm on the Roborock. Two millimetres may seem insignificant, but they make the difference with certain door profiles or transitions between floors. In homes with many small level changes, the Mova models navigate more easily.
The Mova P50 Pro Ultra integrates its own voice assistant, in addition to compatibility with Alexa and Google Home. This allows controlling the robot through voice commands without depending on external assistants, useful for those who prefer not to link devices to third-party ecosystems. The P50 Ultra and the Roborock only support voice control through Alexa or Google Home.
Multifunctional Cleaning Base
All three models include a multifunctional base with dust self-emptying, mop washing with hot water and drying with hot air. The key difference lies in the washing tray self-cleaning: both Mova models incorporate third-generation system that automatically cleans the tray after each cycle, reducing residue formation and bad odours. The Roborock QV 35S requires periodic manual cleaning of the tray.
The detergent tank is included on the Mova P50 Pro Ultra, is optional on the P50 Ultra (must be purchased separately) and is not available on the Roborock. The detergent is dispensed during mop washing, improving their cleaning and, by extension, the floor. For those who mop daily or with high hygiene demands, it is an interesting feature.
The dust bag capacity is greater on the Mova models: 3.2 litres versus 2.7 on the Roborock. In homes with lots of dirt or several pets, this can mean one or two more weeks between bag changes. The water tanks are identical: 4 litres of clean water and 3.5 of dirty water, sufficient to clean surfaces of 150-200 m² without refilling.
Dimensions
The robot height varies significantly. The Roborock QV 35S measures 96.5 mm, the Mova P50 Ultra 97 mm and the P50 Pro Ultra 103.8 mm. Those additional 7.3 mm on the Pro model may prevent it from passing under low furniture or beds with little clearance from the floor. It is advisable to measure beforehand if there is furniture with tight clearance.
The diameter is practically identical: 350 mm on the Mova models, 353 mm on the Roborock. There are no relevant functional differences in this respect. The Mova bases are wider (420 mm) but less deep (458 mm) than the Roborock's (340 mm wide, 487 mm deep). The Roborock base is also taller: 521 mm versus 470 mm. Depending on available space, it may be easier to fit one or the other.
Real-World Experience
For large homes exceeding 180 m², the Mova P50 Pro Ultra offers the most generous battery life and advanced features that minimise manual interventions. Automatic mop detachment allows daily vacuuming without mopping, and dirt detection guarantees optimal results without supervision. The dual AI camera and pet recognition are especially useful in homes with animals and young children.
The Mova P50 Ultra positions itself as a middle option: it maintains the 19,000 Pa power, extendable side brush and self-cleaning base, but forgoes cameras, dirt detection and automatic mop detachment. It is suitable for those seeking power and good mopping without needing the maximum level of automation. The lower height (97 mm) facilitates access under furniture.
The Roborock QV 35S opts for the reliability of an established brand, with lower power but sufficient for most homes. The absence of mop extension and tray self-cleaning requires greater manual maintenance, but its reduced height and Roborock's reputation for durability and app quality compensate for users who value simplicity and proven technical support.
Conclusion: Which to Choose?
Choose the Mova P50 Pro Ultra if you seek maximum automation and premium features. Ideal for large homes, households with pets, users who value their own voice control and remote camera access. Dirt detection and automatic mop detachment make a difference in daily convenience. Bear in mind its greater height if you have low furniture.
Choose the Mova P50 Ultra if you want 19,000 Pa power and advanced multifunctional base, but can do without AI cameras and intelligent detection features. Good option for medium-large surfaces without pets or with lower demands on obstacle recognition. Its 97 mm height improves access under furniture compared to the Pro model.
Choose the Roborock QV 35S if you prioritise the reliability of a world-leading brand, established app and lower height to pass under furniture. Suitable for homes up to 150-180 m² without need for maximum power. Requires somewhat more manual maintenance on the washing tray, but offers the peace of mind of a manufacturer with years of experience and proven technical support.
