Included accessories are documented in unboxing/setup coverage, including cleaning solution, fragrance modules, and an extra vacuum bag.
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.
Threshold and barrier crossing are repeatedly described as strong, helping the robot move between rooms and surfaces with less assistance.
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.
Reviewers repeatedly praised the textured, refined design and said the robot and dock look more premium than budget-oriented.
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.
App automation, smart-home integrations, Matter support, and voice control are recurring strengths in the reviews.
BLAST airflow is described as stabilizing suction while also helping hair move off the brush instead of wrapping.
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.
The robot can climb onto and maintain area rugs, but thicker rugs were described as more mixed than low-pile surfaces.
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 consistently described as easy, with straightforward docking, app pairing, and quick start-to-map workflows.
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.
Fast charging and recharge/resume behavior were praised across several reviews, especially the short top-up time at the dock.
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.
One review said the dock dust bag should last weeks in an average household, suggesting reasonable bag capacity.
Build quality appears strong in the available reviews, with comments describing strong build quality, a well-made feel, and solid overall construction.
Build impressions were sturdy and refined overall, though one review also noted some top-cover scratching after use.
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.
Deep high-pile carpet cleaning is the clearest weakness, with mixed or below-average results in the review set.
Low-pile carpet evidence is limited but favorable, with one review summary calling short-pile carpet performance very good.
Low-pile rug cleaning was reported as strong in routine use, including embedded hair pickup.
Medium-pile evidence is limited but positive, with one test summary calling medium-pile results solid.
Child-lock support appears in dock/control discussion, where child lock limits touchscreen usefulness and one app walkthrough lists a child-lock option.
Clogging prevention is a major claimed and observed advantage. Reviews describe filters staying cleaner, low clogging rates, and cyclonic separation preventing performance drop.
Anti-tangle and scraper elements helped prevent hair jams and other brush-related clogs in testing.
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.
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.
App control was described as clean and easy to use, with room, schedule, zone, and no-go controls, though one reviewer noted weaker overall app polish.
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 improved versus simpler robots but still not among the strongest areas of performance.
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.
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.
One firsthand review specifically reported no clogging or auto-empty failures during testing.
The dock empty cycle is short, but it is clearly loud.
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.
Multiple reviewers said the roller system handled dried footprints, sticky residue, or dried drink messes well.
Ease of use is supported by a reviewer calling the robot super easy to use in the context of common robot-vacuum challenges.
Reviewers repeatedly framed the M16 as easy to live with because automation cuts manual effort.
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 are better than basic robot mops thanks to extend/reach features, though not every reviewer thought it was class-leading.
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.
Wall-following and edge-first behavior were described as orderly and accurate.
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.
Automatic dust handling reduces direct contact with mess and extends time between emptying tasks.
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.
The sealed bag and filter setup were described as a more hygienic way to contain dust during emptying.
Floors were described as only slightly damp and quick to dry after mopping.
Floorhead design centers on the DuoSpiral brush and a main brush gap intended to manage hair and improve cleaning behavior.
Reviewers highlighted the conical anti-tangle brush and enlarged roller mop as key hardware upgrades.
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.
At least one liquid test showed fast cleanup of spills without much fuss.
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.
Hair pickup on carpet and rugs was good in routine use, even if deep carpet extraction was not best-in-class.
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.
Pet hair pickup on hard floors was repeatedly described as strong.
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.
Anti-tangle performance is one of the clearest strengths, with several reviewers reporting little or no hair wrapping.
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.
Fine dust pickup on hard floors was a clear strength in everyday testing.
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.
Multiple reviews said it handled larger hard-floor debris well, often in one pass.
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.
The dock’s heated washing system is presented as a meaningful part of the automated cleaning experience.
Innovation is supported by unique-fragrance coverage, CES recognition, in-robot cyclone discussion, and reviewers calling the system advanced or distinctive.
Reviewers repeatedly framed the M16 as unusually feature-rich for its price and as a meaningful step up versus earlier or pricier models.
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.
Larger dry debris such as crumbs, coffee grounds, or snacks were generally handled well.
Low-profile evidence is limited to one review saying the robot fits under most furniture.
The low 95 mm profile helps the robot reach low-clearance areas more easily.
Maintenance is a key strength. Reviewers cite minimal maintenance, months before real attention, easier upkeep, cleaner filters, and less need to intervene.
Ownership is lower-effort than many robots, but it still requires periodic brush, filter, roller, and sensor checks.
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.
Mapping was described as quick and accurate, with neat pathing and sensible room segmentation.
Mop lifting is strongly supported by multiple reviews, including automatic mop lift, carpet-wetness prevention, and 28 mm lift claims.
The mop-lift system was repeatedly noted as effective for protecting carpets and thicker rugs during mopping.
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 one of the strongest parts of the package, especially for everyday grime, sticky spills, and more active scrubbing.
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.
Regular cleaning is usually described as quiet or manageable, but dock emptying and higher-power cleaning are noticeably louder.
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 a frequent strength, especially around furniture and smaller floor objects, though not flawless in every test.
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.
Warm-air drying and self-cleaning were repeatedly credited with reducing musty smells and odor buildup.
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.
Bags, filters, and brushes add ongoing cost, but one review did not find the ownership costs unusually high for the category.
Cleaning convenience is strong in the evidence, with reviewers citing long hands-off runtime and set-it-and-forget-it use.
A major theme across reviews is that the M16 removes routine floor care from the owner’s to-do list.
Longevity claims center on sustained performance: reviewers describe peak-performance maintenance for up to 365 days and consistent cleaning results over extended use.
Early durability impressions were positive, but the review evidence is still short-term rather than long-term.
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 multiple reviewers explicitly recommending the M16 despite some tradeoffs.
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.
One firsthand review specifically called the M16 ideal for homes with pets and mixed flooring because it keeps up with pet-related debris.
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.
Value was framed positively when reviewers considered the feature set against the asking price.
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.
Coverage is solid for larger homes, but maximum-power carpet runs reduce runtime and area coverage.
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.
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 self-wash and self-dry cycle was repeatedly praised for reducing hands-on upkeep.
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.
A dedicated cleaning-solution system and active water delivery were repeatedly treated as meaningful upgrades for mopping and self-cleaning.
The dock footprint is generally favorable, with coverage noting a relatively small footprint and a narrow base station that can fit in more places.
The dock is slimmer or more compact than some competitors, but it can still feel large for cramped placements.
Residue and streaking results are positive in supported tests, with no visible streaking and surfaces left clean without visible residue.
Residue control was consistently positive, with repeated claims of low streaking and cleaner mopping passes.
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.
The robot generally avoids getting stuck on common obstacles better than older designs, though cords still need some caution.
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 reviews, suction is consistently described as strong for daily cleaning, though one measured test found deep-carpet extraction less impressive than the specs suggest.
Heavy-duty suitability is supported by one extended-use review estimating over 20,000 square feet cleaned and more than 40 hours of runtime.
The M16 is repeatedly positioned as a good fit for busy, high-traffic homes that need strong daily upkeep.
Small-space suitability is supported by a reviewer saying the robot fits under most furniture.
The dock is more apartment-friendly than some competitors, but extremely tight spaces are still not ideal.
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.
Its slim body and good clearance help it reach under sofas, cabinets, beds, and other low furniture.
Value-for-money is mixed; one detailed comparison said a less expensive Eufy model offers better value despite the S2’s flagship strengths.
Discounted launch pricing made at least one reviewer especially enthusiastic about the overall value-for-money case.
Versatility is supported by evidence across hard floors, carpets, pet hair, rooms, and zones, including app-based cleaning by room or specific zone.
Reviewers treated the M16 as a flexible all-rounder that can vacuum, mop, and handle mixed-surface household cleaning.
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 clean and dirty water tanks were described as easy to manage, with refill and empty cycles every few days in one home.
