Included accessories are documented in unboxing/setup coverage, including cleaning solution, fragrance modules, and an extra vacuum bag.
Replacement and upkeep items are available as kits including brushes, filters, bags, and a roller mop, which helps with long-term maintenance planning.
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 handling is described as capable for typical door transitions, with some reviewers noting it can climb modest height changes without drama.
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.
Most reviews like the flagship look, often calling out the black and rose-gold styling and a more squared, modern station design, though the overall footprint is still large for a mop-capable system.
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 features are broadly considered flagship-level, including mapping, scheduling, room-by-room control, and detailed cleaning settings, though a minority report stability or editing limitations.
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.
Mop lifting helps keep many low rugs and some medium-pile carpets drier during mixed-floor runs, though very plush rugs may still need caution.
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 straightforward, but several reviews mention minor hiccups such as Wi-Fi pairing retries, initial docking alignment, or the robot briefly failing to find the base.
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 performance is generally adequate for typical spaces and supports recharge-and-resume, but measured efficiency is not best-in-class and max-power modes can drain faster.
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 disposable bag system that can go weeks to months between changes, but the robot’s onboard bin is small in some tests, making the dock more important for heavy hair or debris.
Build quality appears strong in the available reviews, with comments describing strong build quality, a well-made feel, and solid overall construction.
Build quality is described as solid but not as premium-feeling as some top-tier rivals, with concerns centering on plastics and long-term wear of fixed components.
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.
Low-pile carpet evidence is limited but favorable, with one review summary calling short-pile carpet performance very good.
Low-pile carpet cleaning is generally strong for everyday debris and hair, though deep extraction is not always leading its category.
Medium-pile evidence is limited but positive, with one test summary calling medium-pile results solid.
Carpet deep-clean results are generally good but not class-leading in at least one benchmark, landing closer to average when extracting deeply embedded grit.
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.
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.
Compared to pricier flagships, reviews often position it as competitive on suction and especially strong on mopping, with navigation and battery being the main areas where it may trail.
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.
Controls lean heavily on the app, which reviewers generally find clear and full-featured, though a few report quirks when editing maps or managing rooms.
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 performance is consistently strong, aided by an extending side brush and edge-focused behaviors that improve coverage in tight angles.
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.
Several tests report strong pickup along trim and into narrow gaps, helping it clean edges where debris collects.
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.
Dirty-water related alerts help prompt tank emptying, but at least one reviewer found the wording confusing at first.
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 automation are strong overall, handling emptying, tank management, and mop care, but a few reviews mention first-run docking alignment issues or occasional base-finding quirks.
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 stain performance is a major strength in tests, especially for coffee-type marks, though very large spills can still create messy edge cases near the dock.
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 flexible cleaning presets and clear in-app settings that make it simple to choose quick or deep cleans.
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 standout, helped by extending brushes and an edge-focused roller-mop design that reaches closer to walls than many rivals.
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.
Auto-emptying into a bag and contained disposal are praised, though very large spill cleanups can leave some mess near the dock during the return-to-base process.
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.
Drying time is generally fast thanks to lower residual water left by the roller system and controlled water delivery.
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.
The roller system is repeatedly credited with better handling of wet messes because it can scrub while reclaiming dirty liquid rather than spreading it around.
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 pet-hair pickup is repeatedly excellent in testing, outperforming many combo robots on flattened hair benchmarks.
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 consistently rated strong, especially in homes with shedding pets.
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 a major highlight, with combing/cutting or active removal features reducing brush wrap even with long hair.
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.
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 and everyday tracked-in mess are generally picked up easily, but side-brush scattering can occur with certain medium items on hard floors.
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.
Hot-water washing and hot-air drying in the dock are repeatedly called out as premium features that help keep the roller mop cleaner and reduce manual scrubbing.
Innovation is supported by unique-fragrance coverage, CES recognition, in-robot cyclone discussion, and reviewers calling the system advanced or distinctive.
Innovation is most often credited to the extendable roller-mop approach and the dock’s hot-wash/hot-dry automation, which differentiate it from many spinning-pad designs.
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.
Low-profile claims are mixed: some reviewers appreciate the flat-top design for furniture reach, while others note its measured height is not dramatically slimmer than many lidar-tower bots.
Maintenance is a key strength. Reviewers cite minimal maintenance, months before real attention, easier upkeep, cleaner filters, and less need to intervene.
Day-to-day maintenance is mostly hands-off due to the dock, but occasional manual cleaning is needed after unusual messes and some reviewers dislike components that are harder to remove or service.
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 and path efficiency are usually rated as solid and fairly fast, but a few reviews report occasional map oddities, less-direct routes than premium leaders, or rare moments of confusion.
Mop lifting is strongly supported by multiple reviews, including automatic mop lift, carpet-wetness prevention, and 28 mm lift claims.
Automatic mop lift enables mixed hard floor and carpet cleaning in one run, and reviewers generally find it effective for keeping carpets from getting wet.
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 consistently the hero feature, with the roller mop delivering strong stain removal, good edge reach, and better wet-mess handling than many pad-based designs.
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.
Multiple reviewers highlight unusually quiet operation for a vacuum-mop robot, making it easier to run while people are home.
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 above average with camera and 3D sensing, but thin cables and strings remain a common weakness across real homes.
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 experiences are mixed: hot-air drying is intended to reduce musty smells, but a few reviewers noticed a temporary plastic or warm-material smell during early use.
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.
Ongoing costs are viewed as manageable, with periodic replacement of bags, filters, brushes, and the roller mop being the main recurring expenses.
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.
Packaging evidence is narrow but positive, with one unboxing noting a large, easy-to-read quick-start card and documentation.
Packaging is often praised for being easy to unbox and more eco-friendly than typical, with reduced foam and less waste, plus protective outer boxing in some cases.
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.
Reviewers consistently call it pet-friendly, citing strong day-to-day hair pickup and systems designed to keep hair from bogging down performance.
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 is frequently framed as strongest when discounted, delivering many flagship features and mopping performance at a lower price than top competitors.
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.
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.
Self-cleaning behaviors are a core highlight, with automated mop washing/drying and dock-assisted upkeep reducing the need for frequent manual cleaning.
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.
Some reviews note the lack of a detergent tank or cleaning-solution system, which may matter to users who prefer mopping with solution rather than water-only 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.
Residue and streaking results are positive in supported tests, with no visible streaking and surfaces left clean without visible residue.
Streaking and residue control is usually a strength of the roller mop because it leaves less water behind, but a few reviewers notice visible tracks on light floors.
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.
Stuck resistance is good in normal homes but not flawless; cables, strings, and some tight furniture layouts can still snag the robot or trigger recovery events.
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 repeatedly described as very strong for the class and effective on daily dirt, dust, and pet hair. A few testers note that high power can contribute to side-brush scattering with certain debris on hard floors.
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.
The dock delivers strong automation but takes up meaningful space, so small homes may need to plan placement carefully.
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.
Reliability sentiment is mostly positive in daily use, but some reviewers express concern about warranty support or long-term serviceability of non-removable parts.
Under-furniture pickup is supported by one hands-on review saying the robot got into tight spaces under cabinets and under a bed.
The flatter top design helps it reach under more furniture in some homes, improving coverage where taller lidar-tower robots may 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 dual-tank dock system is praised for making mopping more hands-free, though refill/empty frequency varies and some reviewers note fill lines or tank access could be clearer.
