Included accessories are documented in unboxing/setup coverage, including cleaning solution, fragrance modules, and an extra vacuum bag.
Reviews mention a well-equipped ecosystem with included consumables (bags/cleaning tools/solution) and optional accessories like a hair-cutting roller. Add-ons can improve hair handling but can also add to ownership cost.
Adaptive chassis lift is clearly supported by specifications and hands-on discussion, including automatic chassis lift, wheel-height adjustment, and lift behavior on carpets or transitions.
Design is repeatedly praised as sleek, premium, modern, and visually distinctive, with several reviewers calling out the translucent top, ring light, and slim or home-friendly styling.
Design opinions are mixed: at least one reviewer says the dock looks dated or appliance-like compared with newer, more aesthetic competitors. Most other reviews focus more on function than finish.
Smart features are a major part of the product, with CleanMind AI, floor-type detection, 3D mapping, app controls, and automation praised, though app disconnects and limited smart-home controls were also reported.
Automation is a major theme: reviewers cite advanced obstacle avoidance, dirt detection with extra passes, customizable schedules, no-go zones, and pet-focused modes. The tradeoff for all that power is a larger settings surface area, and some reviewers find the app experience less polished.
Area-rug handling is generally strong, with evidence around avoiding tassels, preventing rug bunching, planning paths around rug edges, and adapting to different rug types.
Carpet and rug handling is often praised because the robot can lift the mops and, in some modes, leave mop pads at the dock to avoid wetting textiles. A dissenting note is that mop hardware can still catch on some carpet edges or that pad removal is not always automatic, so settings matter.
Setup is consistently described as straightforward or easy, with coverage mentioning simple setup steps, easy app-driven setup, and a base station that is mostly assembled.
Setup is generally described as quick, with guided app onboarding and fast mapping runs. Reviewers report it is straightforward to get from unboxing to a usable map.
Bag-level visibility is a weakness in the critical app review, which notes no real-time access to dust bag levels.
Battery and charging evidence is mixed but concrete: one hands-on review measured a roughly 4.8-hour recharge time and noted that battery life varies significantly by suction level.
Battery life is described as long, with a large battery (often cited as 6,400mAh) and support for recharge-and-resume. Reviewers generally expect it to handle larger homes, though thorough mop routines can still take time.
Bin handling is supported by a hands-on note that overfilling the bin may require more than one empty cycle, so capacity and emptying behavior are good but not unlimited.
The dock uses a large disposable dust bag (often cited as 3.2L), reducing how often you deal with dust. However, some reviewers note bag replacement frequency and bag pricing can vary with usage and contribute to ongoing costs.
Build quality appears strong in the available reviews, with comments describing strong build quality, a well-made feel, and solid overall construction.
Only a few sources discuss durability directly, but the comments that do are positive, noting robust wearing parts and a generally well-built feel. No review in the file reports major structural failures.
High-pile carpet coverage is mixed. Several sources praise lift and thick-rug capability, but detailed testing found carpet performance underwhelming compared with expectations and some competitors.
At least one review notes noticeably strong performance on thicker or higher-pile carpet due to high suction. Keeping carpets dry is helped by vacuum-only modes, mop lifting, or leaving mop pads at the dock, but some testers still caution about mop height when crossing carpet edges.
Low-pile carpet evidence is limited but favorable, with one review summary calling short-pile carpet performance very good.
On low-pile carpet, multiple sources report strong pickup and good deep-clean behavior, though stubborn pet fur may require repeat passes. Overall performance is consistently above average for a robot vacuum-mop.
Medium-pile evidence is limited but positive, with one test summary calling medium-pile results solid.
For embedded debris in carpet, test-driven reviews report above-average deep-clean performance and strong suction delivery. Carpet deep-clean scores are described as near the top tier of current robot vacuums.
Child-lock support appears in dock/control discussion, where child lock limits touchscreen usefulness and one app walkthrough lists a child-lock option.
A child lock is mentioned as available, helping prevent accidental starts or setting changes. It is treated as a nice-to-have safety feature rather than a core performance driver.
Clogging prevention is a major claimed and observed advantage. Reviews describe filters staying cleaner, low clogging rates, and cyclonic separation preventing performance drop.
Hair-cutting and brush-lifting behaviors are cited as practical ways to prevent gunk and tangles, especially when the robot encounters wet patches. Reviewers generally frame these as helpful for keeping the cleaning path cleaner and reducing manual cleanup.
Comparison evidence is extensive. Reviewers compare the S2 against the S1 Pro, E25/E28, and competing flagships, finding meaningful upgrades in some areas but weaker value or carpet performance in others.
In comparisons, the X40 Ultra is often positioned as a top performer, earning high marks for vacuuming, mopping, and obstacle avoidance versus other flagships. A few reviewers note that the very best competitors are close, so the final choice can come down to price and preferred features.
Controls are generally positive. Reviewers cite a clean, easy app, touch controls or displays, full app functionality, and 3D map controls, though one detailed test found smart-home integration limited.
The app offers deep controls (maps, zones, schedules, no-go lines, and automation toggles), and many reviewers find it powerful. A recurring downside is UI complexity: some call it clunky or overwhelming until you tune settings.
Corner cleaning is improved but not perfect. Reviews praise extending brushes and corner reach, while some still want longer deployment or more aggressive behavior.
Corner cleaning is repeatedly praised thanks to an extendable side brush and edge-focused routines. Reviewers describe better corner reach than robots that rely on a fixed brush setup.
Crevice and groove pickup is mixed. One reviewer says it can get into cracks in wood or tile, while another found grout-line grime only partly removed.
Cyclone performance is one of the strongest technical themes. Reviews discuss multi-cyclone separation, in-robot cyclone technology, and stable airflow that helps keep filters from clogging.
Dirty-water or dirt-sensing support is limited to sources describing intelligent dirt detection that can trigger an additional cleaning cycle if used water is very dirty.
Some reviews highlight a dirty-water sensing approach that can trigger extra mop-pad washing or a second cleaning pass when the system detects heavier soil. This feature is presented as a meaningful upgrade for messier kitchens and high-traffic areas.
Docking and auto-empty reliability are strongly supported. The station is described as handling emptying, washing, drying, refilling, maintenance cycles, dirty water, and debris with little intervention.
Docking and auto-empty are generally described as reliable, with a full-service station that empties dust and maintains the mops. One review flags weaker auto-empty suction and higher bag usage than expected, so performance may vary by debris load and settings.
Dried-on stain evidence is mostly positive but not uniform. Reviews cite dried-on residue, sauce, and overnight spill tests, though one first-look source had not yet verified whether higher mop force made it better.
Dried-on mess performance is a standout: multiple reviews describe the spinning mop system and extra-pass behaviors as excellent on sticky or dried spills (such as coffee). It is frequently positioned as among the best moppers in its class.
Ease of use is supported by a reviewer calling the robot super easy to use in the context of common robot-vacuum challenges.
Ease of use is generally high once set up, with strong automation and helpful app guidance. The main usability complaint is that the app and feature set can feel complex at first.
Edge and baseboard performance is mixed. Many sources praise the extending mop or side brush, while detailed tests report visible gaps or inconsistent edge behavior near walls, cabinets, and baseboards.
Edge and baseboard cleaning is a consistent strength thanks to an extending mop pad and edge-reaching behaviors. Multiple reviewers highlight noticeably better along-the-wall pickup compared with robots that cannot extend to edges.
Edge-following accuracy is a weakness in the critical hands-on testing, with reviewers noting the robot rides off walls and that edge behavior cannot be adjusted in the app.
Emptying and mess control are positive overall, with hands-on reviewers saying the self-emptying dock handled thick hair without clogs and the stronger dock cleared the robot bin thoroughly.
Filter or accessory tracking is supported by app evidence showing accessory wear tracking, though it is not described as a direct filter sensor.
Filtration is a standout area in the hands-on coverage. Reviewers describe clean-looking filters after use, cyclonic filtration keeping the dustbin filter clear, and fine particles being separated before air returns to the room.
One test-focused review notes that after cleaning wet spills the floor was not left overly damp, suggesting good water control. In general, the spinning mop system aims to clean effectively without soaking floors.
Floorhead design centers on the DuoSpiral brush and a main brush gap intended to manage hair and improve cleaning behavior.
Floor shine evidence is limited but positive, with one hands-on review saying floors looked clean and shiny after mopping.
Fresh liquid pickup evidence comes from first-look coverage explaining that the roller mop design is especially good for processing liquid spills.
Hair-removal channel evidence points to the center-gap brush design, which channels hair into the dustbin and reduces stuck strands.
Carpet hair pickup is strong in the evidence, with reviews calling pet-hair carpet performance very strong and long-hair/pet homes a good fit.
Carpet hair pickup gets conflicting feedback: some coverage labels it a top option for homes with pets, but at least one lab-style test found only average fur removal in a single run. Multiple passes, higher suction, and the right brush can matter here.
Hard-floor hair pickup is supported by reviewers describing hair, dust, and debris handled well and fine dust or loose hair picked up during hard-floor style tests.
Hair pickup on hard floors is mixed: some reviewers call it excellent for pet hair, while at least one test-focused review found it left a meaningful amount behind without multiple passes. Expect best results with tuned settings and the right brush configuration.
Hair-wrap resistance is one of the most consistent strengths. Nearly all hands-on sources praise the DuoSpiral or gap-based brush for preventing tangles and reducing manual hair removal.
Tangle resistance is also mixed: long hair can still wrap around the main roller in some reports, but anti-tangle side-brush design and optional hair-cutting rollers are described as effective upgrades. Cleaning hair out is generally considered manageable.
Hard-floor fine-dust pickup is strong in the available evidence, including hard-floor praise and tests involving dust or fine particles on hard surfaces.
Hard-floor fine debris pickup is described as excellent, with test-style reviews reporting near-perfect results on materials like sand. It is regularly characterized as thorough on hard surfaces.
Large hard-floor debris pickup is supported by cereal, candy, peanuts, sprinkles, and other medium debris tests, where the S2 generally picked debris up well.
Large-debris pickup on hard floors is generally strong, with high percentages reported in testing and good real-world pickup. A minor recurring note is that a single pass can miss a few crumbs, which is solvable with extra passes or higher settings.
Lighting support is narrow but present: one walkthrough notes a light for dark areas and tight spaces.
Heating evidence centers on dock functions such as hot-water mop washing, hot-air drying, and 60°C water for cleaning the mop roller.
A heated mop-wash is repeatedly mentioned, with hot water used in the dock to clean mop pads and the washboard. Reviewers connect the heating to better mop-pad cleanliness and reduced odor.
Innovation is supported by unique-fragrance coverage, CES recognition, in-robot cyclone discussion, and reviewers calling the system advanced or distinctive.
Innovation shows up in features like leaving mop pads at the dock, lifting brushes when sensing liquid, edge-extending mops and brushes, camera-assisted stain attention, and sensor-driven re-cleaning. Reviewers frequently call these capabilities differentiators versus simpler robot vacuum-mops.
Kid-friendliness is supported by one reviewer emphasizing pets or kids crawling around in the context of electrolyzed-water cleaning and chemical-free sanitation claims.
Large-debris handling is supported by tests with heavier or medium-sized debris, with reviewers saying the robot pulled everything in cleanly or picked up everyday debris quickly.
Low-profile evidence is limited to one review saying the robot fits under most furniture.
Maintenance is a key strength. Reviewers cite minimal maintenance, months before real attention, easier upkeep, cleaner filters, and less need to intervene.
Maintenance is described as low day-to-day because the dock empties dust and washes and dries mop pads automatically. Owners still need to refill clean water, empty dirty water, replace bags, and occasionally wipe sensors and check brushes.
Maneuverability is supported by room-transition and movement evidence: reviews describe moving between rooms without help and smooth motor behavior with no jerking.
Mapping and path efficiency are well covered through 3D mapping, room routing, furniture identification, and app maps, with several reviewers saying the robot builds detailed maps quickly or accurately.
Navigation and mapping are repeatedly described as top-tier, with fast mapping and strong coverage efficiency. Some testers note occasional pattern quirks, but overall it is seen as reliable at completing whole-home cleans.
Mop lifting is strongly supported by multiple reviews, including automatic mop lift, carpet-wetness prevention, and 28 mm lift claims.
The mop system can lift during carpet detection and, in some workflows, leave mop pads at the dock to keep rugs dry. Most reviewers view this as a major advantage, though one notes the lift height may still snag on some carpet edges.
Mopping performance is the S2’s strongest repeated theme. Reviews praise clean hard floors, active self-washing, pressure, stain handling, and no residue, though edge coverage and extreme stains remain caveats.
Mopping is widely rated as a top-tier strength, driven by spinning pads, edge extension, and options for extra passes on dirtier areas. Some reviewers caution that the most aggressive automated modes can be overkill on delicate finishes until tuned.
Noise was a noted tradeoff. One reviewer called it louder than recent flagship bots, while another measured about 65.5 dB on quiet and 81 dB on max; a later benchmark also flagged the 81 dB peak as above average.
Noise is acceptable on lower settings but becomes noticeably loud at maximum suction, which some reviewers frame as the cost of stronger vacuuming. One lab-style test measured it as louder than average, and reviewers recommend scheduling loud runs when you are out.
Obstacle avoidance is broadly capable but imperfect. Some reviewers report zero collisions or strong object avoidance, while detailed testing found a 71% obstacle score and minor bumps with everyday clutter.
Obstacle avoidance is one of the most consistently celebrated strengths, with multiple sources citing camera and structured-light sensing and near-perfect avoidance results. Cables can still be a challenge for any robot, but overall confidence is high.
Odor control is polarizing. Some reviewers liked the fragrance or odor-reduction approach, while the most critical hands-on review said the deodorizer did not make a noticeable difference during or after cleaning.
Odor control is generally praised because the dock both hot-washes and hot-dries the mop pads, reducing musty smells. This is repeatedly mentioned as helpful for keeping the system from getting funky between cleanings.
Ownership-cost evidence is limited to fragrance refills: one reviewer liked the modules up close but said refills were not worth personally recommending because the scent was not noticeable during cleaning.
Running costs come up as a concern in some coverage, mainly around disposable dust bags and other consumables. Reviewers recommend factoring consumables into ownership cost, even if day-to-day maintenance is low.
Cleaning convenience is strong in the evidence, with reviewers citing long hands-off runtime and set-it-and-forget-it use.
Longevity claims center on sustained performance: reviewers describe peak-performance maintenance for up to 365 days and consistent cleaning results over extended use.
Overall opinion is generally favorable but not unanimous. Some reviewers call it one of the best or near-perfect, while a detailed tester describes it as strong but specialized.
Overall sentiment is strongly positive, with several sources ranking it at or near the top among flagship robot vacuum-mops. The most common reservations are the high price, the size of the dock, and mixed reports on pet-hair pickup consistency.
Packaging evidence is narrow but positive, with one unboxing noting a large, easy-to-read quick-start card and documentation.
Pet relevance is supported by a reviewer with dogs, who discussed odor control, hair challenges, and household pet mess concerns while describing the S2 as useful in that setting.
Pet-oriented features are a highlight: reviewers mention pet zones, avoidance of bowls and toys, and camera-based monitoring (including two-way video in some coverage). Performance with pet hair is more mixed, but overall the feature set is considered very pet-friendly.
Price is a caution point. The S2 is repeatedly tied to a high flagship price, with reviewers noting $1,599.99 or €1,599 and one saying the price was higher than expected.
Price is the most consistent negative: several reviews describe it as a premium, top-of-the-market model. Many still consider the performance and automation strong enough to justify it for the right home, especially when discounted, but value is weaker for budget shoppers.
Privacy control support is indirect but relevant: one reviewer noted the S2 does not have video monitoring mode, framing that as good news for privacy-minded users.
Runtime is mixed. Some coverage highlights long runtimes, but one detailed test found coverage varies widely by suction setting and drops sharply on max suction.
Sanitizing performance is widely mentioned through electrolyzed or ozone water claims, with multiple sources citing 99.99% sterilization or bacteria reduction; one source noted Eufy had not provided much specificity.
Sanitizing claims are tied mainly to the dock washing mop pads with very hot water (often stated around 158F). Reviews treat this as a hygiene win for the mop pads, not a guarantee of disinfecting the entire floor.
Self-cleaning is a core strength. Reviews describe mop self-cleaning, hot-water station washing, a mop that looks brand new, and station-based cleaning after each run.
The dock self-cleans and maintains the mopping system by washing pads and the washboard and drying with hot air, often with scrapers and repeat-clean logic. This is repeatedly credited for reducing hands-on upkeep and improving hygiene.
Software support is evidenced by hands-on reviewers describing frequent firmware updates and improvements, including fixes for issues observed during pre-production use.
The liquid system includes clean and dirty water handling, cleaning solution, and a cleaning cartridge, with reviews describing water tanks and solution use in the dock.
The solution system is frequently mentioned but described differently across sources: it can wash pads with detergent and, in some coverage, dispense floor-cleaning fluid. At least one reviewer notes detergent may be used mainly for mop-pad washing rather than being mixed into the floor water by default.
The dock footprint is generally favorable, with coverage noting a relatively small footprint and a narrow base station that can fit in more places.
Multiple reviewers call out the dock as large and space-consuming, even if the footprint is described as relatively slim in one write-up. Plan for a dedicated spot, especially if you are in a small apartment.
Residue and streaking results are positive in supported tests, with no visible streaking and surfaces left clean without visible residue.
Residue and streak control depends on settings: reviewers mention choosing mopping direction or dialing back aggressive modes to avoid over-mopping certain finishes. When configured, most describe clean results without problematic streaking.
Stuck resistance is supported by threshold and carpet-lift evidence, with reviewers saying it can avoid getting stuck where other vacuums do and can clear obstacles or thresholds.
Reviewers report good stuck resistance, including handling taller thresholds (often cited around 22mm) and completing coverage without frequent rescues. As with most robots, extreme clutter can still cause interruptions, but it is rated highly here.
Reviews consistently point to very strong suction and airflow, including 30,000 Pa claims, 100 air-watt discussion, and reports of strong pickup across debris types. Support was broad, though some carpet tests show that suction alone did not guarantee class-leading deep carpet cleaning.
Across reviewers, suction is repeatedly described as flagship-level, with strong debris pickup on both hard floors and carpets. Several sources cite 12,000Pa suction and top-tier vacuuming results, though max power can be loud and auto-empty strength at the dock is not praised by everyone.
Heavy-duty suitability is supported by one extended-use review estimating over 20,000 square feet cleaned and more than 40 hours of runtime.
Small-space suitability is supported by a reviewer saying the robot fits under most furniture.
Reliability signals are mixed. One source discussed a pre-order recall or hardware issue, another flagged a conservative warranty, while a hands-on reviewer praised ongoing firmware updates to fix issues.
Under-furniture pickup is supported by one hands-on review saying the robot got into tight spaces under cabinets and under a bed.
Under-furniture performance is frequently highlighted, especially around the base of cabinets and appliances where hair and debris collect. Extendable side reach behaviors help it pull debris from areas many robots miss.
Value-for-money is mixed; one detailed comparison said a less expensive Eufy model offers better value despite the S2’s flagship strengths.
Versatility is supported by evidence across hard floors, carpets, pet hair, rooms, and zones, including app-based cleaning by room or specific zone.
Water handling is a core part of the dock system. Reviews mention clean and dirty water tanks, water refilling, larger reservoirs, and back-side dirty water storage.
The system relies on clean and dirty water tanks in the dock and an internal water tank in the robot, which keeps mopping more automated than vacuum-only robots. Expect periodic refills and dirty-water emptying, and some coverage mentions a future-leaning option for auto fill and drain via plumbing.
