Introduction
Roborock continues to dominate the robot vacuum market with two compelling options from its latest lineup. The Roborock Qrevo Edge S5A, launched in 2024, represents a premium solution packed with advanced features designed for demanding households. The Roborock QV 35A arrives in 2025 as a more accessible alternative that maintains core functionality whilst trimming some of the higher-end capabilities.
Both models share Roborock's proven reliability and excellent app integration, making them solid choices for anyone seeking automated cleaning. The real question becomes whether the additional features of the Qrevo Edge S5A justify the investment, or if the QV 35A delivers everything most homes actually need.
Power and Suction
The suction power gap between these models is substantial. The Roborock Qrevo Edge S5A delivers 18,500 Pa, whilst the QV 35A offers 8,000 Pa. This difference becomes particularly noticeable on carpets and when dealing with embedded dirt or pet hair. For homes with thick rugs or multiple pets, the extra suction capability can make daily cleaning noticeably more effective.
The Qrevo Edge S5A features Roborock's DuoDivide anti-tangle brush system, which pushes hair towards the central suction channel to minimise tangles. The QV 35A uses a standard brush without this specialised design. In practical terms, households with long hair or shedding pets will spend less time maintaining the Qrevo Edge S5A's brush.
The side brush configuration differs too. The Qrevo Edge S5A includes an extendable side brush that reaches deeper into corners and along edges. The QV 35A lacks this extension, relying on a fixed side brush instead. Both models feature anti-tangle side brushes, which helps reduce hair wrap-up during cleaning sessions. Neither model offers side brush elevation during mopping, so both retract the brush when mopping mode is active.
Mopping Performance
Both robots use dual rotating mops and can lift them 10mm when encountering carpets or rugs. This prevents wet mops from dragging across fabric surfaces. The mopping systems share the same basic architecture, but the Qrevo Edge S5A adds meaningful enhancements.
The extendable mop feature on the Qrevo Edge S5A allows the mop pads to reach closer to skirting boards and into tight corners. The QV 35A cannot extend its mops, leaving a small gap along edges. For those who value thorough edge mopping, this represents a tangible difference in cleaning coverage.
Dirt detection technology sets the Qrevo Edge S5A apart. This model can identify heavily soiled areas on floors and dirty mop pads, automatically adjusting cleaning intensity or returning to the base for mop washing when needed. The QV 35A lacks these sensors, following predetermined cleaning patterns without adaptive adjustments. In homes with high traffic areas or messy kitchens, the intelligent response of the Qrevo Edge S5A can deliver cleaner results.
Neither model offers hot water floor mopping or automatic mop removal at the base. Both use cold water when mopping floors, though their base stations differ in how they maintain the mops themselves.
Base Station Capabilities
Both models include multifunctional base stations that automatically empty the robot's dustbin, wash the mop pads, and dry them afterwards. The base dimensions and tank capacities are identical: 2.7-litre dust bags, 4-litre clean water tanks, and 3.5-litre dirty water tanks. This gives both models similar maintenance intervals before you need to refill or empty reservoirs.
The critical difference lies in how the bases treat the mop pads. The Roborock Qrevo Edge S5A washes mops with hot water and dries them with heated air. This combination removes stubborn stains more effectively and accelerates drying, reducing the risk of unpleasant odours or bacterial growth. The QV 35A uses cold water washing and ambient air drying, which still cleans the mops but with less intensity and slower drying times.
The Qrevo Edge S5A features tray self-cleaning 2.0, automatically maintaining the base station's washing tray to prevent residue build-up. The QV 35A doesn't include this automated tray maintenance, requiring occasional manual cleaning to keep the base hygienic.
Neither base station includes UV disinfection, detergent dispensers, or plumbing connection options. Both rely on manual water tank management.
Navigation System
Navigation technology is nearly identical between these models. Both use 3D LiDAR towers for mapping and obstacle avoidance. Neither includes AI cameras, frontal 3D laser sensors, LED lighting for night vision, or remote camera access. Pet recognition and curtain detection aren't available on either model.
The software intelligence differs slightly. The Qrevo Edge S5A runs SmartPlan 2.0, whilst the QV 35A uses SmartPlan 1.0. The newer version on the Qrevo Edge S5A offers more sophisticated room recognition and cleaning sequence optimisation. The Qrevo Edge S5A also operates on the RR Mason 11.0 processor, though specific details about the QV 35A's processor aren't specified.
Both robots can climb obstacles up to 20mm high, handling door thresholds and thick carpet edges without difficulty. Voice assistant compatibility through Alexa and Google Home is standard on both models.
Battery and Autonomy
Battery specifications are identical. Both models pack 5,200 mAh batteries delivering 180 minutes of runtime. This autonomy suits medium to large homes comfortably, typically covering 200-250 square metres on a single charge depending on floor type and cleaning mode intensity.
Charging times aren't specified for either model, but Roborock robots typically recharge in three to four hours. The matched battery capacity means both robots will handle similar-sized homes without needing mid-clean recharging.
Intelligent Features
Neither model includes a robotic arm or proprietary voice assistant. Both support external voice control through standard smart home platforms. The 20mm obstacle climbing capability is consistent across both models, allowing them to navigate typical household obstacles like carpet transitions and door strips.
The SmartPlan differences mentioned earlier represent the main intelligence gap. The Qrevo Edge S5A's enhanced planning algorithms, combined with its dirt detection sensors, create a more adaptive cleaning experience compared to the QV 35A's more conventional approach.
Dimensions
The robots are nearly identical in size. The Roborock QV 35A measures 353mm in diameter and stands 96.5mm tall. The Qrevo Edge S5A is fractionally smaller at 352mm diameter but slightly taller at 98mm. In practical terms, the 1.5mm height difference is negligible when considering clearance under furniture.
Both should fit under most sofas and beds with standard clearance. The base stations share identical dimensions at 340mm wide, 521mm tall, and 487mm deep, requiring the same floor space in your home.
Dustbin capacity in the robots themselves is virtually identical: 325ml for the Qrevo Edge S5A and 330ml for the QV 35A. Both carry 80ml water tanks for mopping between base visits.
Real-World Usage Scenarios
For homes with pets, the Roborock Qrevo Edge S5A offers clear advantages. The DuoDivide brush reduces hair tangles significantly, whilst the superior 18,500 Pa suction pulls embedded fur from carpets more effectively. The hot water mop washing also helps remove paw prints and pet-related stains more thoroughly.
In larger homes, both models provide sufficient battery life, but the Qrevo Edge S5A's dirt detection means it won't waste time over-cleaning already pristine areas whilst ensuring heavily soiled zones receive extra attention. This intelligent resource allocation can actually improve efficiency in spacious properties.
The QV 35A suits smaller flats or homes with primarily hard floors and minimal carpet coverage. The 8,000 Pa suction handles everyday dust and crumbs competently on tile, laminate, or wood flooring. Without pets or high-traffic areas requiring intensive cleaning, the simplified feature set still delivers satisfactory results.
Maintenance effort differs between the models. The Qrevo Edge S5A's self-cleaning tray and hot air drying reduce hands-on upkeep, whilst the QV 35A requires more frequent manual base cleaning and longer mop drying times.
Conclusion: Which Should You Choose?
Choose the Roborock Qrevo Edge S5A if: You have pets that shed, multiple carpets or rugs requiring deep cleaning, or larger homes where intelligent dirt detection improves efficiency. The extendable side brush and mop deliver superior edge coverage, whilst hot water washing and heated drying keep the base station more hygienic with less manual intervention. This model suits those wanting the best robot aspirador Roborock currently offers.
Choose the Roborock QV 35A if: You live in a smaller home with predominantly hard floors, don't have shedding pets, and prefer a more budget-conscious option. The 8,000 Pa suction and standard brush handle everyday cleaning tasks effectively, and the multifunctional base still provides automated maintenance even without heated washing. This represents solid value for straightforward cleaning needs without premium features you may not actually use.
The differences between these robot aspirador models are substantial enough to matter. The Qrevo Edge S5A justifies its premium positioning through measurably better performance in suction, edge cleaning, and adaptive intelligence. The QV 35A delivers competent baseline functionality for less demanding environments. Your home's specific challenges—pet hair, carpet coverage, floor area, and desired automation level—should guide this decision more than any single specification.
