Power and Suction
Suction power creates a significant gap between these models. The Dreame L10s Ultra Gen 3 reaches 25,000 Pa, a substantial advantage over the Roborock Qrevo Edge S5A's 18,500 Pa. In practical terms, this difference becomes noticeable when tackling embedded dirt in carpets or dealing with pet hair ground into textured flooring.
The main brush systems take different approaches. Dreame opts for a simpler brush design, whilst Roborock implements their DuoDivide anti-tangle technology. The DuoDivide system channels hair towards the central suction point, reducing the frustrating tangles that plague many robot vacuums. For households with long hair or shedding pets, this matters more than the raw suction figures might suggest.
Both models feature extendable side brushes for improved corner cleaning. However, the Roborock distinguishes itself with anti-tangle technology on the side brush as well. The Dreame lacks this feature, which could mean more frequent maintenance for those dealing with hair accumulation. Neither model elevates the main or side brushes during mopping, so both maintain consistent floor contact throughout the cleaning cycle.
Mopping Performance
Both robots use dual rotating mops, but their edge-cleaning strategies differ. The Dreame L10s Ultra Gen 3 employs Roboswing technology, a distinctive movement that allows the robot to angle the mop slightly under furniture edges and skirting boards. The Roborock Qrevo Edge S5A uses standard mop extension without this swivelling motion.
Mop elevation differs by half a millimetre: 10.5 mm on the Dreame versus 10 mm on the Roborock. Whilst minimal, this could determine whether mops clear certain low-pile rugs or raised thresholds. Both systems lift sufficiently to protect most carpets during vacuuming-only passes.
The base washing systems reveal a crucial difference. Roborock washes mops with hot water, which proves more effective at breaking down grease and stubborn marks. The Dreame uses cold water for mop cleaning, though both dry with hot air afterwards. For homes with sticky kitchen floors or high foot traffic, the hot water washing on the Qrevo Edge S5A delivers better hygiene.
Only the Roborock detects dirt on both mops and floors, triggering additional cleaning passes when needed. The Dreame lacks this adaptive response, following predetermined cleaning patterns regardless of actual soil levels. This makes the Roborock more efficient in homes where mess concentrates in specific areas like entryways or under dining tables.
Navigation System
Both models navigate using 3D LiDAR towers, creating detailed floor plans and efficient cleaning routes. The Dreame L10s Ultra Gen 3 adds a frontal 3D laser sensor, enhancing obstacle detection at ground level. This sensor helps identify smaller objects that might sit below the LiDAR's scanning plane.
The Dreame also recognises pets specifically, potentially adjusting cleaning patterns around animals or their belongings. The Roborock Qrevo Edge S5A doesn't offer dedicated pet recognition, though its obstacle avoidance still functions effectively.
Neither robot includes a camera, LED lighting, or remote viewing capabilities. The Roborock runs on RR Mason 11.0 processing with SmartPlan 2.0 intelligence, whilst Dreame uses CleanGenius AI without specifying the processor. Both work with external voice assistants like Alexa and Google Home, but neither features an onboard voice assistant.
Battery and Autonomy
Battery capacity matches at 5,200 mAh for both models, yet runtime differs considerably. The Dreame L10s Ultra Gen 3 operates for 231 minutes on a single charge, whilst the Roborock Qrevo Edge S5A manages 180 minutes. This 51-minute difference translates to roughly 20-25% more coverage area before requiring a recharge.
For larger homes exceeding 150 square metres, the extended autonomy of the Dreame reduces the likelihood of mid-clean returns to base. The Roborock's 180 minutes still covers most average-sized homes comfortably, but sprawling layouts with multiple rooms might trigger recharge cycles.
Smart Features
Both robots clear obstacles up to 20 mm high, handling standard door thresholds and low-profile room transitions without assistance. Neither includes a robotic arm or proprietary voice assistant, keeping the focus on core cleaning functions rather than experimental features.
The Dreame's CleanGenius AI and Roborock's SmartPlan 2.0 both optimise cleaning routes and adapt to room layouts. The practical difference emerges in how the Roborock's dirt detection influences real-time decisions, whilst the Dreame relies more on pre-planned efficiency.
Multifunctional Base Station
Both bases handle the essential tasks: auto-emptying dust, washing mops, and drying with hot air. The Dreame L10s Ultra Gen 3 features third-generation base self-cleaning, an evolution from the Roborock's 2.0 system. This newer technology should reduce maintenance frequency and prevent residue buildup more effectively.
Capacity favours the Dreame across the board. The dust bag holds 3.2 litres versus 2.7 litres on the Roborock. Clean water storage reaches 4.5 litres compared to 4 litres, whilst dirty water collects in 4 litres versus 3.5 litres. For households running multiple cleaning cycles between refills, these differences extend the interval between manual intervention.
The Dreame includes a detergent dispenser, automatically adding cleaning solution during mop washing. The Roborock lacks this feature, relying on water alone. Whilst not essential, the detergent option enhances cleaning performance on stubborn marks without requiring manual preparation.
Dreame offers an optional connection kit for plumbing integration, purchased separately. This allows the base to refill and drain autonomously when installed near water pipes. The Roborock doesn't provide this option, though neither comes with integrated plumbing connections as standard.
Dimensions
The robots measure nearly identically. The Dreame spans 350 mm diameter and stands 97 mm tall, whilst the Roborock measures 352 mm across and 98 mm high. These millimetre differences won't affect clearance under furniture in any meaningful way.
Base dimensions show more variation. Both measure 340 mm wide, but the Dreame rises to 590 mm tall compared to the Roborock's 521 mm. The Roborock extends deeper at 487 mm versus 457 mm on the Dreame. The taller Dreame base might not fit under certain counters or shelving, whilst the deeper Roborock requires more floor space front-to-back.
Real-World Usage Experience
The Dreame L10s Ultra Gen 3 suits homes prioritising raw cleaning power and extended autonomy. The 25,000 Pa suction tackles thick carpets and embedded debris more aggressively, whilst the 231-minute runtime covers expansive floor plans without interruption. The larger tank capacities mean less frequent maintenance, appealing to users who want maximum hands-off operation. The detergent dispenser and third-generation base cleaning add convenience for those seeking the latest technology.
Households with significant pet hair or long human hair might find the simpler brush design requires more frequent detangling compared to the Roborock's anti-tangle system. The cold water mop washing remains effective for general maintenance but may struggle with greasier messes.
The Roborock Qrevo Edge S5A excels in homes where intelligent adaptation matters more than peak power. The DuoDivide brush system significantly reduces hair tangles, saving time on maintenance. Hot water mop washing delivers superior hygiene, particularly valuable in kitchens or homes with young children. The dirt detection sensors ensure thorough cleaning without wasting time on already-clean areas, making the shorter 180-minute runtime less of a limitation in practice.
The slightly smaller capacities still accommodate most weekly cleaning routines comfortably. For homes under 150 square metres with moderate soiling, the Roborock's smarter cleaning approach may prove more valuable than the Dreame's brute force.
Conclusion: Which to Choose?
