Introduction
Choosing a robot vacuum involves analysing what you really need in your day-to-day life. The Dreame L10s Ultra Gen 3 comes with 25,000 Pa suction power and a third-generation multifunction base, designed for those seeking complete autonomy in cleaning and mopping. The Roborock Q7 L5 o BF is presented as a more basic option, with 8,000 Pa suction and a simple charging base, without self-emptying or mop washing functions. The Roborock Qrevo S5V sits at an intermediate point with 12,000 Pa, a multifunction base and advanced navigation system.
We're looking at three very different propositions. The Dreame model opts for maximum power and automated functions, whilst the Q7 L5 o BF represents a more traditional solution for those who prefer simplicity. The Qrevo S5V combines Roborock technology with balanced features.
Power and Suction
The difference in suction power sets the pace for this comparison. The Dreame L10s Ultra Gen 3 triples the capacity of the Roborock Q7 L5 o BF with its 25,000 Pa, a figure that's particularly noticeable on carpets and when there are pets at home. The Qrevo S5V stays at 12,000 Pa, sufficient for most situations but clearly below the Dreame model.
As for brushes, the Dreame incorporates a SimpliCut brush designed to reduce tangles, whilst the Q7 L5 o BF features a traditional bristle brush. The Qrevo S5V opts for Roborock's DuoDivide Antienredos system, which pushes hair towards the centre to facilitate suction.
The extendable side brush of the Dreame L10s Ultra Gen 3 improves corner cleaning, something that neither the Q7 L5 o BF nor the Qrevo S5V offer. The latter does include an anti-tangle side brush, a useful detail if you have long hair or pets. None of the three models lifts the main brush during mopping, nor the side brush either.
Mopping
Here the differences are enormous. The Dreame L10s Ultra Gen 3 and the Roborock Qrevo S5V feature two rotating mops that spin whilst mopping, a much more effective system than the static mop of the Q7 L5 o BF. Additionally, the Dreame extends the mops with Roboswing movement to better reach edges and tuck slightly under furniture. The Qrevo S5V also extends its mops, although without that additional movement.
Mop lifting reaches 10.5 mm in the Dreame and 10 mm in the Qrevo S5V, sufficient to climb onto thin carpets without wetting them. The Q7 L5 o BF doesn't lift the mops, which limits its use in homes with carpets.
Mop washing during and after cleaning is only available in the Dreame L10s Ultra Gen 3 and the Qrevo S5V. The Dreame washes with hot water, whilst the Qrevo S5V uses cold water. Drying also makes a difference: hot air in the Dreame versus cold air in the Qrevo S5V. The Q7 L5 o BF doesn't wash or dry the mops because it lacks a multifunction base, which means you must clean them manually after each use.
Navigation System
All three models use LiDAR turret to map the home, but the similarities end there. The Dreame L10s Ultra Gen 3 incorporates a front 3D laser sensor to avoid obstacles and recognises pets, functions that improve the robot's autonomy in complex environments. The Qrevo S5V also includes obstacle avoidance, although without the 3D laser sensor of the Dreame.
The Roborock Q7 L5 o BF doesn't have obstacle avoidance or pet recognition. This means it can get stuck more easily if there are toys, cables or slippers on the floor.
Regarding artificial intelligence, the Dreame integrates CleanGenius whilst the Qrevo S5V uses Roborock's SmartPlan. The Q7 L5 o BF doesn't have AI-based intelligent cleaning. None of the three incorporates an AI camera, remote camera access or night vision LED.
Autonomy and Battery
The Dreame L10s Ultra Gen 3 and the Roborock Qrevo S5V share a 5,200 mAh battery, although the Dreame makes better use of it, reaching 231 minutes of autonomy versus the 180 of the Qrevo S5V. The Q7 L5 o BF stays at 3,200 mAh, a notably lower capacity that doesn't come with autonomy data in minutes.
This difference is decisive in large homes. With 231 minutes, the Dreame can clean large surfaces without needing to return to charge mid-cycle. The Qrevo S5V offers sufficient autonomy for most homes, whilst the Q7 L5 o BF may require intermediate recharges in flats over 100 square metres.
Smart Functions
All three robots overcome obstacles up to 20 mm in height, which allows them to navigate small level changes such as thick carpets or transitions between rooms. None incorporates a robotic arm or its own voice assistant, although all three are compatible with Alexa and Google Home for voice control.
Multifunction Cleaning Base
The base of the Dreame L10s Ultra Gen 3 represents its greatest advantage. It includes self-emptying of the dust bin, mop washing with hot water and drying with hot air. The 3.2-litre dust bag lasts several weeks without changing it. The clean water (4.5 litres) and dirty water (4 litres) tanks allow multiple mopping cycles without manual intervention.
The third-generation tray self-cleaning of the Dreame reduces maintenance, and the detergent tank automatically dispenses product during mop washing. Additionally, there's an optional kit to connect the base to water pipes, although it must be purchased separately.
The Roborock Qrevo S5V also has a multifunction base, but washes the mops with cold water and dries them with cold air, less efficient processes than those of the Dreame. Its dust bag is 2.7 litres and the clean water (4 litres) and dirty water (3.5 litres) tanks are slightly smaller. It doesn't include tray self-cleaning or a detergent tank.
The Roborock Q7 L5 o BF only offers a charging base. You must empty the robot's dust bin manually after each use and clean the mop by hand. There's no data on tank capacity because it doesn't have a self-emptying system.
Dimensions
The Roborock Q7 L5 o BF is the most compact at 325 mm in diameter and 99 mm in height. The Dreame L10s Ultra Gen 3 measures 350 mm in diameter and 97 mm in height, whilst the Qrevo S5V reaches 353 mm in diameter and 96.5 mm in height. In practice, these differences barely affect the ability to get under furniture, although the Qrevo S5V is the lowest by half a millimetre.
The bases show more evident differences. The Dreame's occupies 340 mm in width, 590 mm in height and 457 mm in depth. The Qrevo S5V has similar dimensions: 340 mm in width, 521 mm in height and 487 mm in depth. The base of the Q7 L5 o BF is much smaller (160 x 101 x 70 mm) because it only serves to charge the robot.
Real-World Usage Experience
In large homes, the Dreame L10s Ultra Gen 3 stands out for its 231-minute autonomy and 25,000 Pa power. The multifunction base allows you to forget about maintenance for weeks, ideal if you spend a lot of time away from home. The extendable side brush and mop extension with Roboswing improve cleaning in corners and edges.
For homes with pets, the Dreame excels again thanks to its power, SimpliCut brush and pet recognition. The Qrevo S5V also works well with its DuoDivide Antienredos brush and obstacle avoidance, although its lower power may be noticeable on hair embedded in carpets.
The Roborock Q7 L5 o BF fits better in small flats without carpets and with few mopping demands. Lacking a multifunction base, it requires more manual attention but takes up much less space. Its static mop and lower power limit the results in mopping and deep vacuuming.
Mopping makes important differences. The Dreame washes the mops with hot water and dries them with hot air, which guarantees clean mops without bad odours. The Qrevo S5V performs with cold water and air, although the process is slower. The Q7 L5 o BF forces you to wash the mop by hand each time, something tedious if you mop daily.
Conclusion: Which to Choose?
Choose the Dreame L10s Ultra Gen 3 if you're looking for the best robot in this comparison without compromises. Its 25,000 Pa power, third-generation multifunction base with hot water, detergent tank and 231-minute autonomy make it the most complete option. Perfect for large houses, homes with pets, people with little time for maintenance and those who value truly effective mopping. The extendable side brush and Roboswing system provide an extra benefit in edges and corners.
Choose the Roborock Q7 L5 o BF if you live in a small flat, don't have carpets and prefer a simple robot without complications. Its compact base barely takes up space and the price is usually much more affordable. You accept that you'll need to empty the dust and clean the mop manually, but in return you get a functional basic model from a reliable brand. It's not the best option if you have pets or need intensive mopping.
Choose the Roborock Qrevo S5V if you want a balance between technology and price. Its multifunction base, navigation system with obstacle avoidance, DuoDivide Antienredos brush and 12,000 Pa power cover the needs of most homes. It works well with pets thanks to the anti-tangle brush, although without specific animal recognition. The 180-minute autonomy is sufficient for medium-sized homes. It falls below the Dreame in power, autonomy and base features, but represents a solid alternative with Roborock's backing.
