Introduction
The Dreame L50s Pro Ultra and the Roborock Q7 L5+ or BF+ Plus represent two distinct philosophies within the world of robot vacuum cleaners. The former is a 2026 model that opts for maximum technology and automation, whilst the latter arrived in 2025 as a more accessible proposition focused on the essentials: vacuuming effectively and self-emptying without complications.
The difference between both devices is notable from the first glance at their specifications. We're looking at a high-end robot versus a mid-range one, designed for users with very different needs and expectations. The Dreame model seeks to offer almost total autonomous cleaning, with mopping included, whilst the Roborock focuses on powerful vacuuming with the addition of self-emptying.
Power and Suction
The difference in suction power is enormous. The Dreame L50s Pro Ultra reaches 30,000 Pa, a figure that more than triples the 8,000 Pa of the Roborock Q7 L5+ or BF+ Plus. In practice, this translates into superior capability to extract ingrained dirt from carpets and absorb heavier particles.
The brushing system also marks distances. The Dreame device mounts a dual HyperStream brush, designed specifically to prevent hair tangles, something that proves essential in homes with pets. The Roborock uses a conventional bristle brush, more prone to accumulating long hair and pet fur.
Additionally, the Dreame incorporates main and side brush lifting, along with an extendable anti-tangle side brush. This allows the robot to adapt its sweeping system according to floor type and improve cleaning in corners. The Roborock model lacks these functions, maintaining a more basic brushing system without adaptation capability.
Mopping
Here we find the greatest difference between both models. The Dreame L50s Pro Ultra integrates a complete mopping system with two rotating mops that extend to reach edges and skirting boards, including the Roboswing system that allows the robot to make a lateral movement to clean under furniture overhangs. The mops lift up to 10.5 mm when the robot detects carpets or when it only needs to vacuum.
The Roborock Q7 L5+ or BF+ Plus features a static mop without lifting or extension capability. It cannot remove the mops automatically at the base, which means that if we want to alternate between vacuuming and mopping, we'll have to do it manually.
The Dreame's multifunction base washes the mops with hot water during cleaning and upon completion, then dries them with hot air. This ensures that the robot always mops with clean mops and prevents bad odours. It also includes third-generation washing tray self-cleaning and detergent dispenser. The Roborock simply doesn't have these capabilities: its base only handles dust emptying.
The Dreame also detects dirt both on the mops and on the floor, adjusting its behaviour to go over dirtier areas again. A function that makes a difference in the final mopping result.
Navigation System
Both robots employ 3D LiDAR turret to map the home, but the Dreame goes much further. It incorporates dual camera with artificial intelligence capable of recognising up to 220 different types of obstacles, including pets and curtains. This allows it to avoid cables, socks, pet excrement and other objects with precision.
The Dreame's front 3D laser sensor complements navigation to detect low obstacles and furniture in greater detail. Additionally, it features night vision LED and remote camera access, which allows supervising the home from the app whilst the robot cleans.
The Roborock Q7 L5+ or BF+ Plus limits itself to LiDAR for navigation, without intelligent obstacle avoidance or camera recognition. It's a functional and reliable system, but less sophisticated. For homes with many objects on the floor or pets, the difference will be notable.
Autonomy and Battery
The Dreame L50s Pro Ultra features a 5,200 mAh battery, versus the 3,200 mAh of the Roborock. Although we don't have exact autonomy data in minutes, the capacity difference suggests that the Dreame model will be able to cover larger surfaces without needing to recharge mid-clean.
This proves especially relevant in large homes or when mopping is activated, which consumes more battery by forcing the robot to make several trips to the base to wash the mops.
Smart Functions
The Dreame L50s Pro Ultra can overcome simple steps, whilst the Roborock reaches 20 mm in height. Both can navigate small level changes such as those of carpets or transitions between rooms, although the Roborock's figure is more specific.
An exclusive function of the Dreame is its own voice assistant, which allows interacting directly with the robot without needing intermediaries. The Roborock only offers compatibility with Alexa and Google Home, which remains useful but requires an additional smart speaker.
The Dreame's CleanGenius AI system automatically adjusts suction power, water flow and cleaning pattern according to the detected dirt level. The Roborock lacks this adaptive intelligence.
Multifunction Cleaning Base
The Dreame L50s Pro Ultra's base is a complete maintenance station. In addition to self-emptying, it washes and dries the mops with hot water and air, cleans its own washing tray, dispenses detergent and allows automatically removing the mops when we only want to vacuum. The dust bag has a capacity of 3.2 litres, and the clean and dirty water tanks reach 4.5 and 4 litres respectively. There's also an optional kit to connect it to the home's plumbing, although it must be purchased separately.
The Roborock Q7 L5+ or BF+ Plus base focuses exclusively on self-emptying the dust container. Its bag has a capacity of 2.7 litres. It doesn't wash or dry mops because this robot's mopping system is much more basic. For those seeking only automatic vacuuming, it perfectly fulfils its function.
Dimensions
The Roborock Q7 L5+ or BF+ Plus is more compact: 325 mm in diameter and 99 mm in height, which allows it to slip under low furniture more easily. The Dreame L50s Pro Ultra measures 350 mm in diameter and 103.8 mm high, slightly larger dimensions that may limit its access under some low sofas or beds.
The size difference in the bases is considerable. The Roborock's occupies 212 mm wide, 259 mm high and 178 mm deep, a compact format easy to position. The Dreame's station reaches 340 mm wide, 590 mm high and 457 mm deep, occupying considerably more space due to all the systems it integrates.
It's advisable to measure the available space carefully before deciding on the Dreame, especially if we're planning to place the base in a corner or cupboard.
Real-World User Experience
The Dreame L50s Pro Ultra is designed for users seeking to completely forget about daily cleaning. Its 30,000 Pa power, dual anti-tangle brush and large battery capacity make it ideal for large homes with pets. The mopping system with automatic mop washing and drying guarantees optimal results on hard floors without manual intervention.
The intelligent navigation with recognition of 220 obstacles drastically reduces jams and allows the robot to work unsupervised even in homes with young children or animals. Remote camera access adds an extra peace of mind.
The Roborock Q7 L5+ or BF+ Plus suits better those who prioritise vacuuming over mopping, or smaller homes where the 3,200 mAh battery proves sufficient. Its lower height facilitates cleaning under low furniture, and the compact base doesn't require as much space. It's a solid option if we don't need automated mopping or prefer to mop manually.
For homes with thick carpets, the Dreame's power makes a difference. Conversely, if we only have hard floors and few carpets, the Roborock can perform without problems.
Conclusion: Which to Choose?
Choose the Dreame L50s Pro Ultra if you're looking for a robot that vacuums and mops in a completely autonomous manner, you have a large home, you live with pets that shed hair, you value intelligent navigation with obstacle avoidance and you don't mind investing in latest-generation technology. The multifunction base with mop washing and drying with hot water and air justifies the price difference if you're genuinely going to take advantage of the mopping.
Choose the Roborock Q7 L5+ or BF+ Plus if you primarily need a good vacuum cleaner with self-emptying, your home isn't excessively large, you don't have pets or you're not too concerned about hair tangles, and you prefer a more compact and straightforward solution. Also if you have low furniture under which you need the robot to pass without problems, or if mopping isn't a priority and you prefer to do it manually when necessary.
