Introduction
The Roborock Qrevo S5V and Roborock QV 35A represent the manufacturer's 2025 lineup, both featuring multifunction bases that handle automatic emptying, mop washing, and drying. These are comprehensive cleaning systems designed for users who want a hands-off approach to floor maintenance. Whilst they share the same fundamental platform and many identical specifications, the differences between them reveal distinct positioning within Roborock's range.
Both models suit medium to large homes with mixed flooring, though the variations in suction power, brush technology, and base functionality mean they're aimed at slightly different user profiles. Understanding these distinctions helps identify which delivers better value for specific household needs.
Suction Power and Brushing
The most significant performance gap appears in suction capability. The Roborock Qrevo S5V generates 12,000 Pa, which represents a 50% increase over the QV 35A's 8,000 Pa. In practical terms, this extra power becomes noticeable on carpets and rugs, where deeper extraction of embedded dirt and pet hair makes a measurable difference. For homes with multiple carpeted rooms or high-pile rugs, this isn't a trivial distinction.
The brush system reveals another meaningful difference. The S5V features Roborock's DuoDivide anti-tangle design, which channels hair towards the central suction point rather than wrapping it around the roller. The QV 35A uses a simpler conventional brush without this specialised geometry. Pet owners or households with long hair will find the DuoDivide system reduces maintenance frequency considerably—less time spent cutting tangled hair from the roller means less interruption to cleaning routines.
Both models include anti-tangle side brushes, which helps prevent the common issue of hair wrapping around the edge sweeper. Neither offers side brush extension or elevation during mopping, keeping the design relatively straightforward.
Mopping Performance
Both robot aspirador Roborock models use dual rotating mops with 10 mm lift capability, allowing them to raise the pads when transitioning to carpets. The base stations wash these mops with cold water during cleaning sessions and upon completion, maintaining reasonably clean pads throughout the process.
The Qrevo S5V distinguishes itself with extendable mops that reach closer to wall edges and into corners—a feature absent on the QV 35A. This edge extension makes a visible difference in rooms with baseboards or along kitchen plinths, areas that typically require manual attention with standard mopping systems.
Mop drying represents another divergence. The S5V's base employs hot air drying, which accelerates the process and reduces the risk of damp odours developing between cleaning sessions. The QV 35A relies on cold air circulation, which takes longer and may not fully eliminate moisture in humid environments. For those running daily cleaning cycles, the hot air system offers better hygiene outcomes.
Neither model automatically detaches mops at the base for vacuuming-only sessions, nor do they incorporate soil detection systems that trigger additional cleaning passes on particularly dirty areas.
Navigation System
Both units employ identical LiDAR 3.0 turret navigation with obstacle avoidance capabilities and SmartPlan 1.0 intelligent cleaning. This ensures accurate room mapping, efficient path planning, and the ability to navigate around furniture and everyday objects.
Neither model includes AI camera systems, 3D laser sensors, pet recognition, curtain detection, or remote camera access. The navigation remains reliable and systematic but doesn't offer the advanced object identification found in premium models from Roborock's higher tiers. For most households, the LiDAR-based navigation proves entirely adequate for daily cleaning without requiring the additional complexity of visual recognition systems.
Battery and Autonomy
Identical 5,200 mAh batteries power both models, delivering 180 minutes of runtime. This translates to coverage for medium to large homes in a single session, though exact coverage depends on floor type, suction settings, and whether mopping is active. The matching battery specifications mean neither holds an advantage for extended cleaning sessions or multi-storey homes.
Smart Features
Both robots manage 20 mm obstacle climbing, sufficient for standard door thresholds and minor floor transitions. Neither incorporates robotic arms or proprietary voice assistants, though both support external voice control through Alexa and Google Home integration. The smart functionality focuses on practical cleaning automation rather than experimental features, which suits users prioritising reliability over novelty.
Multifunction Base Station
The base stations share most specifications: 2.7-litre dust bags, 4-litre clean water tanks, and 3.5-litre dirty water reservoirs. Both handle automatic emptying after each session and wash mops during and after cleaning cycles. Neither offers automatic mop replacement, UV disinfection, detergent dispensers, or plumbing connection options.
The critical distinction remains the drying method. Hot air drying on the Qrevo S5V provides faster, more thorough results compared to the cold air system on the QV 35A. This becomes particularly relevant in bathrooms or laundry areas where moisture lingers, and in households running multiple cleaning sessions weekly.
Dimensions
At 353 mm diameter and 96.5 mm height, both robots share identical physical dimensions. The bases measure 340 mm wide, 521 mm tall, and 487 mm deep—requiring the same floor space regardless of which model you choose. The 96.5 mm profile allows clearance under most furniture, though very low-slung beds or sofas may still present access challenges.
Real-World Usage Considerations
The Roborock Qrevo S5V makes more sense for homes with pets or residents with long hair, where the DuoDivide brush system reduces maintenance burden. The higher suction also benefits households with thick carpets or rugs that trap dirt below the surface. The extendable mops improve edge cleaning in kitchens, bathrooms, and along skirting boards—areas that otherwise require manual touch-ups.
The QV 35A suits homes with predominantly hard floors, lighter carpet coverage, and less concern about edge mopping precision. The lower suction remains perfectly adequate for daily maintenance in typical conditions, and the simpler brush works fine when hair accumulation isn't a primary concern. The cold air mop drying functions acceptably in drier climates or for users who clean less frequently.
Both models handle medium to large floor plans given the 180-minute runtime, and both navigate effectively around furniture and obstacles. The multifunction bases on each reduce hands-on maintenance to emptying dust bags and refilling water tanks every few weeks, depending on home size and cleaning frequency.
Conclusion: Which to Choose?
Choose the Roborock Qrevo S5V if: you have pets or long-haired household members who'll benefit from the anti-tangle brush design; your home includes substantial carpeted areas where the 12,000 Pa suction delivers noticeably better results; edge cleaning matters because you want mopped floors right up to baseboards without manual intervention; or you run frequent cleaning cycles and want faster, more hygienic mop drying with hot air.
Choose the Roborock QV 35A if: your home features mainly hard floors with minimal carpeting; hair tangling isn't a significant maintenance concern; you're comfortable with slightly less thorough edge mopping; and you want to save money on a capable robot aspirador that still includes a multifunction base with washing and drying capabilities, even if the drying takes longer with cold air.
The price difference between these models typically reflects the enhanced suction, superior brush technology, extendable mopping, and hot air drying on the S5V. For households where those features address specific pain points—particularly pet hair management and carpet cleaning—the upgrade proves worthwhile. For others with simpler cleaning requirements, the QV 35A delivers solid performance at better value.
