Compare Roborock QV 35A Robot Vacuum and Mop vs Roborock S8 MaxV Ultra Robot Vacuum and Mop

Unboxing coverage notes the essentials are included (robot, dock, ramp/base pieces, mop pads), with setup-focused extras rather than a large accessory bundle.

Included extras such as spare bags, guides, and small tools are considered adequate and helpful for getting started and maintaining the dock/robot.

Threshold handling is a standout: reviews report it can climb around half-inch to three-quarter-inch transitions and generally adapts well to small bumps. Wheels and a floating brush/chassis design help maintain contact on uneven surfaces.

Design and finish are frequently praised as premium-looking, with a cleaner, more integrated dock aesthetic than some predecessors.

The Roborock/Qrevo app experience is repeatedly described as excellent and full-featured, with routines, schedules, room/zone cleaning, no-go zones, and deep control over suction, water, and dock behavior. A few notes include needing 2.4 GHz Wi-Fi during setup and (in one review) manually setting floor types for best results.

Automation features are deep: strong scheduling, per-room customization, routines, smart remopping options, and solid voice-assistant integrations-though most advanced controls live in the Roborock app rather than third-party platforms.

During auto-emptying, one review highlights reduced dust puffback thanks to a more sealed, multi-layer bag/door setup. Overall, airflow-related mess during emptying is described as minimal.

Carpet and rug handling is a strength: the robot can detect carpet, lift the mops about 10 mm, and adjust behavior (including carpet boost and vacuum-first options). Some users still prefer to avoid carpets during mopping for best results.

Setup is described as simple: attach the dock base/ramp, fill tanks, scan the QR code, and run quick mapping. A common note is that the robot prefers 2.4 GHz Wi-Fi and docking alignment can take a bit of care.

Setup is repeatedly described as easy: mostly assembled, quick app pairing via QR code, and fast initial mapping/quick-map routines.

The robot reliably returns to dock to charge and includes app options like off-peak charging to reduce energy costs. Reviews do not provide measured runtime numbers, but charging behavior is described as standard and dependable.

Battery life is competitive for a flagship, with measured runtimes around the low-100-minute range in some testing and efficient recharge-and-resume behavior.

The robot bin and dock bag system are considered practical: one review calls out a larger 330 ml onboard bin, while others note bag replacement roughly every 2 to 3 months depending on use (often longer in cleaner homes).

The dock's disposable bag system is viewed as convenient and low-mess, but a few tests noted residual debris remaining in the robot bin after auto-empty on some runs.

Build quality impressions are strong for a budget-leaning model, with reviewers calling out neat finishes, a sturdy bumper, and overall fit-and-finish similar to higher-end Roborock units.

Build quality impressions are strong, with multiple reviews describing solid materials and a well-engineered dock-and-robot system.

For general carpet pickup (especially larger debris), results are described as solid, often improving with a second pass or deep-clean pattern. Hair on carpet is the more common weak point rather than food/debris pickup.

Carpet pickup is a consistent bright spot (including some standout results on larger debris), though performance can vary by test medium (e.g., fine sand) and carpet type.

A child lock is available in the settings, adding peace of mind for households where kids might press buttons or start a run unintentionally.

Child lock is available (often via a long-press on a button) and is presented as a practical safety feature for homes with kids or curious pets.

Comparisons in the reviews often favor the QV 35A on value: several reviewers say it matches or even beats more expensive siblings in basic navigation and cleaning. The main gaps versus pricier models are extra sensors, AI cameras, heated wash/dry, and edge-extending hardware.

Controls are straightforward with physical power/home buttons plus a feature-rich app for room selection, routines, and dock controls. Reviewers also mention adjustable robot voice volume/language and remote-control style driving modes.

Physical controls are straightforward and the in-app controls are robust; the built-in voice assistant can be handy but tends to require exact phrasing.

One setup review specifies the dock power cord is about 6 ft, which is generally sufficient for flexible placement near an outlet.

The dock includes basic cord storage/management, helping keep the power cord tidy behind the station.

Corner performance is described as acceptable but not class-leading. Several reviews point to the lack of extendable brushes/pads as the limiting factor, even though the robot’s perimeter passes still catch a lot along edges.

Corner cleaning improves with the extending side brush and edge mop, and several sources call it better than prior generations, though not perfect in every tight-space scenario.

An LED/fill light helps the front camera see in low light for object detection, though video quality and night performance are not always praised.

Docking, auto-empty, and auto-refill functions are described as reliable in normal use and contribute to the set-and-forget experience. A few notes mention docking alignment can be a little finicky, but overall automation works as intended.

Auto-empty and docking are largely reliable and highly valued for hands-off cleaning; however, a few measurements found residual debris left in the robot bin after emptying, so settings and debris type matter.

Dock operations are generally reported as not super loud, with mop washing and bin emptying described as reasonable and the drying fan often called very quiet.

Dock noise is the main acoustic drawback: mop drying and certain dock cycles are described as noticeable, even if the robot itself is only moderately loud.

Rotating pads and controlled water delivery allow the QV 35A to scrub many dried or sticky spots (e.g., coffee residue, syrup-like spills) surprisingly well. Reviews still emphasize that very large messes may require multiple passes or manual pre-cleaning.

Ease of use is a major positive: reviewers call it convenient to run, easy to set schedules and routines, and largely hands-off thanks to the dock’s washing and emptying. The biggest usability friction points are cable prep and keeping tanks/tray clean for best hygiene.

Day-to-day usability is widely praised: intuitive app flows, quick actions (room/zone/routines), and reliable dock automation reduce the need for babysitting.

Edge cleaning is described as decent in normal perimeter runs, but multiple reviews note it lacks extendable side brushes or mop pads, so edge-to-edge results and tight baseboards can lag behind higher-end models.

Edge and baseboard coverage improves via the edge mop and extending side brush, but results vary by mess type; some tests noted sticky residue or incomplete corner cleanup in tight spaces.

Edge-following behavior is typically accurate and consistent, supporting good wall-hugging coverage and reliable baseboard passes in most reports.

Auto-emptying into a dock bag minimizes hands-on mess and reduces how often the onboard bin needs attention. Reviewers appreciate the cleaner emptying experience versus manual dumping.

Emptying is generally clean and convenient thanks to sealed bags, but a few reviewers observed leftover debris in the robot bin after auto-empty or the need for higher emptying settings.

The app provides maintenance tracking for parts like the filter (remaining life and reminders). Reviewers note you may need to reset timers after cleaning to keep reminders accurate.

The app's consumable tracking for filters/brushes is useful and helps plan upkeep, with reminders tied to estimated wear life rather than a simple calendar.

Filtration is viewed positively: the filter is washable and the docked system is described as good at keeping dust contained, with one review citing SGS certification for high particle capture (e.g., pollen).

Dust containment is aided by sealed disposable bags and hands-off emptying, which reviewers with dust sensitivity appreciated compared with manual bin dumping.

Drying is a known compromise: the dock uses room-temperature air rather than hot air, so pad drying can take many hours (often cited in the 4–8 hour range, with longer options available). This is acceptable to some reviewers but a dealbreaker for others wanting faster hygiene.

Heated drying is considered effective for preventing musty mop smells, but several reviewers note the drying noise is noticeable during its multi-hour cycle.

Hair pickup on carpet is repeatedly described as the biggest cleaning weakness, with rubber brushes struggling to lift embedded hair. Deep-clean patterns help, but some hair may remain compared with bristle-heavy rollers.

On carpets, hair pickup is frequently rated highly in comparative testing (especially for pet hair), though performance can depend on hair length and brush maintenance.

On hard floors, long hair pickup is generally reported as strong, especially when paired with straight-line cleaning and adjustable settings. Some hair can still collect on brushes, but overall pickup is praised.

The anti-tangle design (rubber main brush and redesigned side brush) reduces snarls and makes maintenance easier, but it does not eliminate hair wrap entirely. At least one hands-on test still found noticeable wrap with very long hair.

Hair-wrap resistance is mixed: dual rollers and scrapers help with routine hair, but at least one torture-test showed severe long-hair tangling that can stop the robot.

Fine debris like coffee grounds and small crumbs are reported to be picked up very effectively on hard floors, often with little left after a pass. Reviewers attribute this to strong suction and systematic pathing.

Fine dust pickup on hard floors is good but not class-leading in all lab tests, and some debris can be scattered outward by the long side brush depending on settings and room layout.

Large debris on hard floors (rice, chips, noodles, clumps) is generally handled well, with reviewers commonly seeing most debris removed on the first pass and the rest on a second.

Large debris intake on hard floors is generally strong, but side-brush fling can reduce efficiency and leave grains spread around in worst-case tests.

Innovation is framed as value-focused rather than cutting-edge: reviewers highlight that it skips premium extras like AI camera object recognition, mechanical arms, hot-water washing, hot-air drying, and extendable edge tools. The upside is getting many flagship-like fundamentals at a lower price.

At roughly 3.8 inches tall, the robot is relatively low-profile, but not ultra-slim. Reviewers advise checking furniture clearance if under-sofa cleaning is a priority.

Ongoing maintenance is described as manageable but real: periodic filter washing, sensor wiping, tray rinsing, and dirty tank cleaning are recurring tasks. The removable dock base/tray and clear in-app maintenance timers make upkeep easier.

Maintenance is reduced by the dock, app reminders, and washable components, but owners still need periodic tank changes, bag replacements, and occasional brush/hair cleanup.

Lidar-based mapping and straight-line pathing are consistently praised for neat, efficient coverage. Reviews mention quick mapping, multi-floor support, and accurate 3D-style maps, with predictable perimeter-then-grid cleaning behavior.

Mapping and pathing are widely praised: fast map creation, reliable localization, and strong support for no-go zones and room-level routines.

Mop pads can lift roughly 10 mm when carpet is detected, helping prevent wet rugs. This lift behavior is mentioned across multiple reviews and is treated as reliable and useful.

Mop lift is a major strength: multiple reviews cite high lift height that keeps carpets dry and allows confident vac-and-mop runs in mixed-floor homes.

Dual spinning mops (around 200 RPM) deliver strong scrubbing for routine grime and many stains, with adjustable water flow and the benefit of an onboard tank. For big messes, some smearing can occur and the robot may need extra passes or a manual assist because it lacks advanced dirt-detection re-mop logic.

Mopping is generally strong for a pad-based system (hot-water washing, vibration, and smart re-mopping help), but some comparison tests still place it behind the very best spinning/roller-style moppers on heavy stains.

Noise is generally described as reasonable for a flagship, with some sources noting mid-to-high suction is noticeable; dock drying/maintenance sounds can be more intrusive than the robot itself.

Reactive tech obstacle avoidance is generally good for larger items (furniture, many toys) and can mark obstacles on the map, with adjustable sensitivity. Multiple reviews agree it struggles most with low, thin cables/wires and very small clutter, where bumps or run-overs can happen.

Obstacle avoidance ranges from excellent (avoiding pet waste and many objects) to inconsistent in some lab tests where it tried to run over smaller toys; performance appears sensitive to object type and firmware/settings.

Odor risk centers on the dirty water tank and slow pad drying: several reviewers recommend emptying and rinsing the dirty tank frequently (some even add disinfectant) to prevent foul smells. Neglecting this step is repeatedly called out as a downside.

Hot-water washing and hot-air drying help keep odors down, but reviewers warn that letting dirty water sit too long can create a sewage-like smell common to this category.

Ongoing costs are mainly bags and filters; reviewers generally see them as manageable for a premium system, but they add to the already high upfront price.

Overall sentiment is strongly positive for the price, especially around mapping accuracy, automation via the dock, and solid vacuum+mop performance. Most negatives are framed as expected tradeoffs in a cheaper model (no heated drying, limited edge reach, cable avoidance limits).

Overall sentiment is positive to mixed: many call it a top-tier, low-touch flagship, while a few tests argue its performance tradeoffs and price make it harder to recommend universally.

Packaging is generally described as substantial and protective, reflecting the large dock and accessory set.

Reviewers highlight pet-friendly touches like pet-area deep cleaning settings, strong day-to-day hair control, and solid mopping for muddy paw prints. Heavy carpet hair can still take extra passes and occasional brush cleaning.

Pet-focused coverage is a strength: multiple reviewers cite effective pet hair pickup and solid pet-waste avoidance features, though real-world reliability varies with room clutter and obstacle type.

Value is a consistent theme: most reviews frame the QV 35A as a standout buy when priced under about $500 (and especially when discounted further). Several caution it is less compelling at higher prices because it lacks premium extras like heated wash/dry and edge-extension hardware.

Value is the biggest sticking point: several reviewers call it expensive for the performance delta, while others argue the automation and convenience justify the flagship price if you will use the dock features.

Multiple reviews explicitly note there is no front-facing camera, and one comparison also states no microphone, which can be appealing for privacy-sensitive buyers. The tradeoff is less sophisticated object recognition than camera-based systems.

Privacy controls are a recurring theme: on-device processing is emphasized by some, while others note optional obstacle photos/remote viewing require explicit enablement, passwords, and audible announcements during viewing.

Scratch concerns seem improved versus some older models; at least one reviewer reported no obvious scratching during use.

The dock’s mop washing is repeatedly praised, including agitation in the tray and the ability to remove/rinse the base for easier hygiene. Auto-emptying and tank refills add to the hands-off ownership experience.

The dock does more than empty and wash: multiple reviews mention self-cleaning elements and hot-water mop washing that reduce hands-on cleanup, though periodic manual cleaning is still needed.

Firmware updates are managed through the app, with options for checking or enabling auto-updates. Reviewers describe the update process as accessible and, in at least one case, already up to date out of the box.

Software support appears active (frequent app features, integrations, and ongoing updates discussed), but smart-home ecosystems can lag behind the Roborock app in capability.

The liquid system earns praise for an onboard tank, frequent auto-refills at the dock, and a wide range of adjustable water flow levels. Tradeoffs called out include room-temperature water (no heating) and limited intelligence for automatically re-mopping heavily soiled areas.

The dedicated detergent/solution system is a standout convenience feature, automatically portioning cleaner and helping reduce odors and maintenance hassle.

Cliff/drop sensors are repeatedly mentioned and shown as effective at preventing falls near stairs and edges. Reviewers also note the sensors need occasional wiping to stay accurate.

The all-in-one dock adds a noticeable footprint and needs vertical clearance to remove tanks; one setup walkthrough recommends allowing substantial space above the dock for tank access.

A few tests show smearing can happen on muddy prints or when pads carry dirty liquid before they are washed. Users note that extra passes, better floor-direction settings, or more frequent pad washing can reduce residue.

The robot generally navigates efficiently, but low cables/wires and certain tight areas can still cause issues. Reviewers recommend picking up clutter and using no-go zones, and the app may flag problem spots over time.

Stuck events are uncommon in most accounts, with the robot often able to ride over cords/thresholds without fully halting, though hair tangles can stop cleaning in worst-case scenarios.

Across reviews, 8,000 Pa suction is described as strong for the price and effective for day-to-day pickup on hard floors and rugs, with debris often cleared in one or two passes. Multiple reviewers say it performs similarly to pricier Roborock models in core vacuuming, but it still is not a full replacement for an upright on heavy carpet.

Reviews consistently highlight strong suction (often cited as 10,000Pa) and above-average carpet results, though one lab-style test found it did not dominate fine sand and some hard-floor debris can get pushed around by the side brush.

Reviews caution that, like most robot vacuums, it is best for maintenance cleaning rather than heavy-duty deep cleaning. Homes with lots of thick carpet or extreme debris still benefit from occasional full-size vacuuming.

Customer support is described as friendly and ultimately helpful, but slower than ideal, with back-and-forth email and multi-week resolution mentioned. Day-to-day reliability is generally praised, with the usual caveats around occasional snags and maintenance.

Under-furniture access is good for typical clearances, with multiple reviews showing it can clean beneath some furniture. Its height around 3.8 inches means very low furniture may remain out of reach.

Under-furniture reach benefits from the extending side brush and slimmer edge access, helping capture debris along toe-kicks and under some appliances.

The clean/dirty tank setup is considered convenient and easy to remove, and the robot also carries an onboard water tank that gets refilled at the dock. Multiple reviews warn the dirty tank can smell if left too long, so frequent emptying/rinsing helps.

Clean/dirty tank capacity and usage rate are viewed as competitive; some comparisons suggest it can go longer between water changes than many rivals, though frequency still depends on home size and mopping schedule.
