Dreame L40s Pro Ultra vs Mova P50 Pro Ultra vs Mova Z50 Ultra

Introduction

This robot vacuum comparison brings together three high-end models launched in 2025 that share technological DNA. The Dreame L40s Pro Ultra represents Dreame's premium offering, whilst the Mova P50 Pro Ultra and the Mova Z50 Ultra are two options from their second brand, Mova, each with a different approach.

All three units offer 19,000 Pa of suction power and multifunctional bases with mop washing at 75°C and hot air drying at 45°C. However, differences in the mopping system, battery and some navigation details define distinct usage profiles. The Dreame L40s Pro Ultra and the Mova P50 Pro Ultra opt for rotating mops with RoboSwing extension, whilst the Mova Z50 Ultra incorporates a wide roller with hot water for mopping the floor.

Power and Suction

All three models share the same suction power of 19,000 Pa, sufficient for medium-pile carpets and floors with ingrained dirt. The difference lies in the main brush. The Dreame robot vacuum is equipped with a dual HyperStream anti-tangle brush system, specifically designed to prevent hair from wrapping around. This system uses two brushes anchored at one end that push hair towards the suction inlet without tangling.

The Mova P50 Pro Ultra and the Mova Z50 Ultra feature the TriCut 3.0 brush, which combines bristles with integrated blades that cut tangled hair during use. Both systems work well, although the HyperStream typically requires less maintenance in homes with long-haired pets.

All three robots lift the main brush during mopping to avoid dirtying the mops with dry dust. The side brush is extendable and liftable in all cases, with anti-tangle function included. This allows better sweeping of corners and lifting the brush when only mopping, preventing it from getting unnecessarily wet.

Mopping

Here we find the most significant difference between these models. The Dreame L40s Pro Ultra and the Mova P50 Pro Ultra use two rotating mops that spin at 180 RPM. These mops extend laterally thanks to the RoboSwing movement, which makes the robot perform a small hip turn to tuck the mops under furniture and better reach edges. The mops lift 10.5 mm, sufficient to pass over thin rugs without wetting them.

The Mova Z50 Ultra changes the system completely. It features a wide roller that applies 18N of pressure and, most notably, mops with hot water at 36°C carried in its internal 160 ml tank. This hot water helps better dissolve grease and stuck-on stains. As a complement, it includes a fixed mini side mop that attempts to reach edges, although without the active movement of RoboSwing. The roller lift is 7 mm.

Only the Dreame L40s Pro Ultra and the Mova P50 Pro Ultra can automatically remove the mops at the base when you only want to vacuum. The Mova Z50 Ultra doesn't have this function, which can be less practical if you alternate between vacuuming and mopping depending on the area of the house. All three detect dirt both on the mops and on the floor to adjust cleaning intensity.

Navigation System

All models navigate using 360° LiDAR turret combined with dual AI camera and front 3D laser sensor. This configuration allows precise mapping and real-time obstacle avoidance. The Dreame L40s Pro Ultra recognises up to 180 different types of obstacles, whilst the two Mova robot vacuums recognise 160.

In practice, this difference may be noticeable in homes with many small objects on the floor, although all three units identify pets, curtains and adjust their behaviour according to the type of obstacle. All incorporate LED for night vision and allow remote access to the camera from the app, useful for basic home monitoring.

All three models integrate CleanGenius 2.0, the intelligent cleaning system that automatically adjusts suction power and water flow according to the detected dirt level.

Autonomy and Battery

The Mova Z50 Ultra stands out with a 6,400 mAh battery, superior to the 5,200 mAh of the Dreame L40s Pro Ultra and the Mova P50 Pro Ultra. However, the higher consumption of the hot water system means the actual autonomy is not specified in the table. The Dreame L40s Pro Ultra offers 220 minutes of declared autonomy, compared to 210 minutes for the Mova P50 Pro Ultra.

For homes up to 200-250 m², any of the three models completes cleaning without problems. The Mova Z50 Ultra, with its greater battery capacity and 160 ml water tank in the robot, may be more efficient in large houses where mopping with hot water requires more energy.

Smart Functions

The ability to overcome obstacles marks another important difference. The Dreame L40s Pro Ultra can overcome single steps of 22 mm and double steps up to 40 mm, allowing it to climb thick rugs or small level changes between rooms without getting stuck. The Mova P50 Pro Ultra and the Mova Z50 Ultra are limited to 22 mm on single steps.

All three robots include their own voice assistant and compatibility with Alexa and Google Home. This allows controlling them via voice commands and scheduling cleaning routines without needing to open the app.

Multifunctional Cleaning Base

All three bases perform auto-emptying of the dust bin, mop washing with hot water at 75°C and drying with hot air at 45°C. This high-temperature washing disinfects the mops and eliminates bacteria, whilst hot air drying prevents bad odours.

The Dreame L40s Pro Ultra and the Mova P50 Pro Ultra incorporate third-generation self-cleaning of the washing tray, which automatically cleans the tray where the mops are washed to prevent dirt accumulation. The Mova Z50 Ultra doesn't include this function, which means periodic manual cleaning.

Regarding capacities, the Mova Z50 Ultra has the largest dust bag (4 litres) compared to the 3.2 litres of the other two. The Dreame L40s Pro Ultra and the Mova Z50 Ultra share a 4.5-litre clean water tank, whilst the Mova P50 Pro Ultra has 4 litres. The dirty water tank varies between 4 litres for the Dreame and the Mova Z50 Ultra, and 3.5 litres for the Mova P50 Pro Ultra.

Only the Dreame L40s Pro Ultra offers an optional plumbing connection kit, which is purchased separately and allows connecting the base directly to the drain and water supply. This is worth considering if you're looking for total convenience, although it's not a standard integrated function.

Dimensions

All three robots have the same diameter of 350 mm, standard for high-end robots. The height varies slightly: the Dreame L40s Pro Ultra and the Mova P50 Pro Ultra measure 103.8 mm, whilst the Mova Z50 Ultra reaches 111 mm. Those extra 7 mm can make a difference when passing under certain low furniture or sofas with little clearance from the floor.

The bases have different dimensions. The Mova P50 Pro Ultra is the widest (420 mm) but the shortest (470 mm). The Dreame L40s Pro Ultra is narrower (340 mm) but taller (590.5 mm). The Mova Z50 Ultra falls somewhere in between. These differences affect the space needed to position the base, especially in height if you're planning to place it under furniture or shelving.

Real-World Usage Experience

For large homes with long-haired pets, the Dreame L40s Pro Ultra offers clear advantages: its dual HyperStream brush drastically reduces maintenance, the ability to overcome 40 mm double steps makes it more versatile in homes with level changes, and the RoboSwing system with automatic mop removal provides flexibility.

The Mova P50 Pro Ultra shares many of these advantages (RoboSwing, mop removal, tray self-cleaning), but with the TriCut brush that requires slightly more attention in homes with lots of hair. Its more compact base in height can be an advantage if vertical space is limited.

The Mova Z50 Ultra presents a different approach. Mopping with a roller and hot water at 36°C is more effective on kitchen floors with grease or stuck-on stains. Its greater battery capacity and larger tanks make it suitable for spacious homes where intensive mopping is a priority. However, the absence of automatic mop removal and tray self-cleaning means more manual intervention.

On hard floors (tiles, stoneware, parquet), all three models work well. For carpets, the Dreame L40s Pro Ultra has an advantage due to its ability to overcome higher obstacles. If you frequently pass under low furniture, the Dreame L40s Pro Ultra and the Mova P50 Pro Ultra, with their 103.8 mm height, fit better than the Mova Z50 Ultra.

Conclusion: Which One to Choose?

Choose the Dreame L40s Pro Ultra if you're looking for the best robot vacuum for homes with long-haired pets, need to overcome significant level changes between rooms or thick rugs, value minimal maintenance thanks to the HyperStream brush and want the future option of connecting the base to plumbing. It's the most complete and versatile option of the three.

Choose the Mova P50 Pro Ultra if you want very similar features to the Dreame L40s Pro Ultra with a more compact approach to the base. Ideal for spaces where base height is a limiting factor. It maintains the RoboSwing system, mop removal and tray self-cleaning, with the TriCut brush that works well if you don't have very long-haired pets.

Choose the Mova Z50 Ultra if you prioritise intensive mopping with hot water over the versatility of the rotating mop system. Perfect for kitchens and bathrooms with greasy dirt, large homes where the greater battery and tank capacity make a difference, and you don't mind performing manual cleaning of the washing tray. Its wide roller with constant pressure offers different mopping, more similar to a traditional mop with hot water.
