Introduction
The Dreame L10s Ultra Gen 2, the Roborock QV 35A and the Roborock S8 MaxV Ultra represent three distinct approaches within the high-end range of robot vacuum cleaners with multifunction base. The Dreame model arrived in 2024 featuring rotating mops and a side extension system, whilst Roborock presents two proposals: the QV 35A from 2025 as a more accessible option with rotating mops, and the S8 MaxV Ultra from 2024 as its flagship with vibrating mop technology and dual camera with artificial intelligence.
All three units are designed for users seeking complete automation of mopping and vacuuming, although each one targets different needs depending on the level of artificial intelligence, tank capacity and cleaning systems they incorporate.
Power and Suction
In pure power, the Dreame L10s Ultra Gen 2 and the Roborock S8 MaxV Ultra tie with 10,000 Pa of suction, a figure that allows working with medium-pile carpets without problems. The Roborock QV 35A remains at 8,000 Pa, sufficient for hard floors and thin carpets, although the difference may be noticeable on more demanding surfaces.
The brushing system marks important differences. The S8 MaxV Ultra features a dual silicone brush that pushes debris towards the centre to improve long hair capture, whilst the Dreame and the QV 35A incorporate a single silicone brush. This dual design of the S8 MaxV is especially useful in homes with pets. Additionally, the S8 MaxV Ultra can raise its main brush during mopping, something the other two do not do.
The side brush also presents variations. The S8 MaxV Ultra features an extendable side brush that reaches corners better, a function that neither the Dreame nor the QV 35A offer. The QV 35A incorporates an anti-tangle side brush, a feature absent in the other two models. None of the three can raise the side brush.
Mopping
The mopping system clearly differentiates these robots. The Dreame L10s Ultra Gen 2 opts for two rotating mops at 180 RPM with RoboSwing technology, a lateral movement that extends the mop to reach edges and skirting boards. They rotate at lower speed than those of the Roborock QV 35A, which reach 200 RPM, but the latter does not include any extension system for edges.
The Roborock S8 MaxV Ultra takes a completely different path with its vibrating mop VibraRise 3.0 and a side mini mop that works the edges. This vibrating system offers more delicate mopping on parquet or sensitive floors, whilst the rotating mops of the other two are more aggressive against stuck-on dirt.
Mop lift varies: the S8 MaxV Ultra reaches 20 mm, which allows passing over medium-thickness carpets without wetting them. The Dreame lifts up to 10.5 mm and the QV 35A up to 10 mm, sufficient for thin carpets but limited on thicker ones.
Mop washing in the base marks another substantial difference. The S8 MaxV Ultra washes with hot water at 60°C, much more effective at removing grease and bacteria than the cold water used by the Dreame and the QV 35A. Drying also varies: the S8 MaxV Ultra dries at 60°C with hot air, the Dreame at 45°C, and the QV 35A only with cold air, which lengthens drying time and may encourage bad odours if not well ventilated.
Only the S8 MaxV Ultra detects dirt both on the mops and on the floor, which allows it to re-clean especially dirty areas automatically. This intelligence applied to mopping is not present in the Dreame or the QV 35A. The Dreame and the S8 MaxV Ultra include a detergent tank in the base, whilst the QV 35A lacks one.
Navigation System
All three robots use 360° LiDAR turret for mapping and navigation, but artificial intelligence clearly separates them. The Roborock S8 MaxV Ultra incorporates dual camera with AI capable of recognising 73 different types of obstacles, offers remote camera access for surveillance and features LED for night vision. It can identify pets, cables, shoes and many other objects to avoid them or adapt cleaning.
The Dreame L10s Ultra Gen 2 features front 3D laser sensor and pet recognition, but without camera. This allows it to detect obstacles in three dimensions and adapt the route when it identifies animals, although with less precision than the dual camera system of the S8 MaxV Ultra. The Roborock QV 35A is the most basic in this section: no camera, no 3D sensor, no pet recognition, only standard obstacle avoidance.
Regarding intelligent cleaning, the Dreame features CleanGenius 2.0 and both Roborocks use SmartPlan 1.0, systems that adjust power and passes according to floor type and detected dirt level. The S8 MaxV Ultra adds AI stain recognition, something exclusive to this model.
Battery Life and Battery
All three robots feature 5,200 mAh batteries, but performance differs. The Dreame L10s Ultra Gen 2 offers 240 minutes of battery life, sufficient to clean homes of up to 200-250 m² in a single charge. The Roborock QV 35A and the S8 MaxV Ultra remain at 180 minutes, tighter for large houses but sufficient for most homes.
This 60-minute difference can be decisive in large homes or when complete cleaning is scheduled with vacuuming and mopping in maximum mode. In practice, the Dreame will need to return fewer times to recharge in long sessions.
Smart Features
All three robots can overcome obstacles up to 20 mm in height, such as thick carpets or small level differences between rooms. This capability is identical in all three models.
The Roborock S8 MaxV Ultra incorporates its own voice assistant in addition to compatibility with Alexa and Google Home, which allows giving it orders directly without going through other devices. The Dreame and the QV 35A only work with external assistants. None of the three includes a robotic arm.
Multifunction Cleaning Base
All three bases perform auto-emptying of the dust container, mop washing and drying, but with important differences in capacities and functions. The Dreame L10s Ultra Gen 2 offers the largest dust bag with 3.2 litres, compared to the QV 35A's 2.7 litres and the S8 MaxV Ultra's 2.5 litres. This translates into fewer bag changes throughout the year.
Water tanks also vary. The Dreame features 4.5 litres of clean water and 4 litres of dirty water, the largest capacities of the three. The QV 35A carries 4 litres of clean water and 3.5 of dirty, whilst the S8 MaxV Ultra matches these latter values. In large homes, the Dreame's tanks allow completing more mopping sessions without refilling.
Only the Dreame offers a plumbing connection kit, although it is purchased separately. This option allows completely automating water filling and emptying, although it requires installation and does not come as standard. The 60°C hot water washing of the S8 MaxV Ultra partly compensates for the smaller tanks with more effective mop cleaning.
Dimensions
The Dreame L10s Ultra Gen 2 measures 350 mm in diameter and 97 mm high, which makes it the most compact in diameter and one of the lowest. It can fit under furniture with 10 cm of clearance. The Roborock QV 35A has 353 mm diameter and 96.5 mm height, practically identical. The S8 MaxV Ultra reaches 353 mm diameter but 103 mm high, which may limit its access under some low furniture.
The bases present more marked differences. The Dreame's measures 340 mm wide, 590.5 mm high and 456.7 mm deep. The QV 35A's is 340 mm wide, 521 mm high and 487 mm deep: lower but deeper. The S8 MaxV Ultra's is the widest at 409 mm, but the lowest at 470 mm high and the least deep at 419 mm. It is advisable to measure the available space before deciding, especially if the base goes in a cupboard or specific recess.
Real-world experience
For large homes of over 150 m², the Dreame L10s Ultra Gen 2 is especially practical due to its 240 minutes of battery life and larger water tanks. It can complete full cleans without interruptions to recharge or refill water. Its RoboSwing system works edges well, although the rotating mops can be somewhat aggressive on delicate parquet.
The Roborock QV 35A positions itself as a balanced option for homes up to 120 m². Its 180 minutes of battery life suffice for most homes, and the rotating mops at 200 RPM offer good mopping on hard floors. The absence of advanced obstacle recognition can be a drawback in houses with many objects on the floor or pets.
The Roborock S8 MaxV Ultra stands out in homes with pets and need for supervision. Its dual camera with AI recognises 73 obstacles, identifies pets and allows remote access for surveillance. Mop washing at 60°C and drying at the same temperature guarantee maximum hygiene, important if there are small children or allergies. Its vibrating mop is more delicate on wooden floors than rotating ones. The dual silicone brush works especially well with long hair.
In houses with thick carpets, the 20 mm lift of the S8 MaxV Ultra makes a difference compared to the 10 mm of the Dreame and the QV 35A. If carpets are thin, all three work correctly. For users who value artificial intelligence and remote control, only the S8 MaxV Ultra offers these functions.
Conclusion: Which one to choose?
Choose the Dreame L10s Ultra Gen 2 if you seek maximum battery life and tank capacity. It is ideal for large homes where the 240 minutes of battery and 4.5 litres of clean water allow completing cleans without interruptions. Its RoboSwing system works edges well, and the price is usually more competitive than the Roborocks whilst maintaining 10,000 Pa of power. The 3.2-litre bag reduces the frequency of changes. Good option if you do not need camera with AI but want pet recognition and 3D sensor.
Choose the Roborock QV 35A if your home has up to 120 m² and you seek a more accessible option within the high-end range with multifunction base. Its rotating mops at 200 RPM offer good mopping, and the 180-minute battery life suffices for most homes. It is the simplest option of the three, without pet recognition or 3D sensor, but with Roborock's reliability. The anti-tangle side brush helps if there are cables on the floor. Bear in mind that it does not include a detergent tank in the base.
