Bottom Line
Choose if you want a hands-off flagship that's strong on carpets, edge coverage, and mop-lift to protect rugs. Skip if you're price-sensitive or you have lots of long hair/cord clutter, since some tests show tangling and uneven hard-floor pickup.
Best for
Homes with mixed hard floors and carpets that want a mostly hands-off vacuum+mop with strong mapping, routines, and a self-maintaining dock.
Not for
Shoppers on a strict budget, or homes with lots of long hair and cluttered floors where tangles and small-object avoidance can still be a hassle.
Verdict
Roborock's S8 MaxV Ultra aims for maximum automation: a feature-rich dock that empties, washes with hot water, dispenses detergent, and dries the mop, plus strong mapping and app controls. Across reviews it is consistently excellent at keeping carpets dry thanks to its high mop lift, and it tends to clean edges and corners better than older designs with its FlexiArm side brush and edge mop. The tradeoff is that real-world performance is not uniformly top-tier for the money-some testers saw long-hair tangles, mixed obstacle avoidance, and hard-floor debris getting flung by the side brush. If you value convenience, scheduling, and a capable vacuum-mop combo and can tolerate premium pricing, it's an impressive, mostly hands-off flagship.
Pros
-
Build quality impressions are strong, with multiple reviews describing solid materials and a well-engineered dock-and-robot system.
-
Design and finish are frequently praised as premium-looking, with a cleaner, more integrated dock aesthetic than some predecessors.
-
Dust containment is aided by sealed disposable bags and hands-off emptying, which reviewers with dust sensitivity appreciated compared with manual bin dumping.
-
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.
-
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.
-
Day-to-day usability is widely praised: intuitive app flows, quick actions (room/zone/routines), and reliable dock automation reduce the need for babysitting.
-
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.
-
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.
-
Scratch concerns seem improved versus some older models; at least one reviewer reported no obvious scratching during use.
-
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.
-
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.
-
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.
-
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.
-
Mapping and pathing are widely praised: fast map creation, reliable localization, and strong support for no-go zones and room-level routines.
-
Setup is repeatedly described as easy: mostly assembled, quick app pairing via QR code, and fast initial mapping/quick-map routines.
-
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.
-
Heated drying is considered effective for preventing musty mop smells, but several reviewers note the drying noise is noticeable during its multi-hour cycle.
-
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.
-
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.
-
The dedicated detergent/solution system is a standout convenience feature, automatically portioning cleaner and helping reduce odors and maintenance hassle.
-
Edge-following behavior is typically accurate and consistent, supporting good wall-hugging coverage and reliable baseboard passes in most reports.
-
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.
-
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.
-
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.
-
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.
-
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.
-
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.
-
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.
-
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.
-
Packaging is generally described as substantial and protective, reflecting the large dock and accessory set.
-
Under-furniture reach benefits from the extending side brush and slimmer edge access, helping capture debris along toe-kicks and under some appliances.
-
Included extras such as spare bags, guides, and small tools are considered adequate and helpful for getting started and maintaining the dock/robot.
-
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.
-
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.
-
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.
-
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.
-
Software support appears active (frequent app features, integrations, and ongoing updates discussed), but smart-home ecosystems can lag behind the Roborock app in capability.
-
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.
-
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.
-
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.
-
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.
-
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.
-
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.
-
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.
Cons
-
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.
-
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.
FAQ
Does it keep carpets dry when vacuuming and mopping together?
Most reviews say yes, thanks to its high mop lift; several testers specifically noted dry high-pile carpet during mixed runs. Results still depend on correct carpet detection and settings.
How good is obstacle avoidance for cords and pet waste?
It is often very good at pet waste and larger objects, but smaller toys and cords can still trip it up in some tests. Keeping loose cords picked up and using no-go zones improves reliability.
How often do I need to refill/empty the water tanks?
Expect anywhere from about weekly to every couple of weeks depending on home size, how often you mop, and wash frequency. Larger homes or frequent mopping shorten the interval.
Is the dock loud?
The robot itself is usually moderate, but dock cycles like hot washing and especially hot-air drying can be noticeable for a few hours after mopping.
Is the camera required, and what about privacy?
Core navigation uses LiDAR; the camera helps obstacle recognition. Remote viewing and obstacle photos are optional features that require explicit enablement and can be locked behind a password, with audible announcements during viewing.
