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.
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.
Smart/app features cover the essentials (Wi-Fi app control, mapping, schedules), but reviews note missing or limited voice-assistant support compared with some rivals. Automation is strongest inside the Yeedi app rather than through external ecosystems.
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.
On rugs, it performs well on low-pile area rugs for vacuuming, but mopping around rugs requires care and planning. Homes with many rugs benefit from no-mop zones or running vacuum-only on rug-heavy areas.
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.
Setup is widely described as straightforward, with quick app pairing and mapping after initial runs. Some users note you may need to learn the vacuum-vs-mop configuration steps early to avoid confusion.
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.
Bag-level visibility is a weakness in the critical app review, which notes no real-time access to dust bag levels.
Battery and charging behavior is described as dependable, with enough endurance for typical apartments/medium homes and expected recharge behavior when needed. Long sessions may involve recharge-and-resume depending on floorplan and settings.
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.
Bin/bag capacity is viewed as a strong point for the class, with a usable onboard bin and a larger base collection capacity that reduces daily maintenance. This setup supports longer stretches between manual empties for most households.
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.
Build quality impressions are generally solid for the price tier, with a functional, mid-range feel rather than premium materials. Long-term durability is viewed as reasonable, though a few reviews raise typical reliability caveats for budget robots.
Build quality appears strong in the available reviews, with comments describing strong build quality, a well-made feel, and solid overall construction.
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 pickup is consistently reported as strong for routine maintenance, with enough suction to lift daily dust and hair. Deep cleaning still benefits from occasional manual vacuuming.
Low-pile carpet evidence is limited but favorable, with one review summary calling short-pile carpet performance very good.
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.
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 and UI (especially in-app) are generally described as easy to use, with clear mapping, room selection, and scheduling. Occasional limitations are mentioned around deeper smart-home integration.
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.
Corner cleaning is acceptable but not class-leading; several reviews note it can leave some debris in tight corners, especially compared to higher-end robots with more advanced edge strategies.
Corner cleaning is improved but not perfect. Reviews praise extending brushes and corner reach, while some still want longer deployment or more aggressive behavior.
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-emptying are generally reliable, with the base consistently collecting debris after runs. The station is simpler than self-washing mop docks, but it delivers the core convenience of hands-off dust disposal.
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.
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.
Ease of use is high for day-to-day vacuuming and scheduled runs, especially with auto-emptying. Mopping is less effortless because it can require manual pad handling and configuration changes.
Ease of use is supported by a reviewer calling the robot super easy to use in the context of common robot-vacuum challenges.
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 performance is frequently called out as only okay, with some reviewers explicitly noting it is not great on edges/baseboards. It can miss fine debris right against walls without occasional targeted runs.
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 is convenient and largely mess-controlled thanks to the auto-empty dock, reducing how often users handle the onboard bin. A few reviews still recommend routine checks to prevent overfill or clogs, especially with heavy hair.
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.
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 generally good on low-pile surfaces, with enough power for maintenance. For homes with lots of hair on thicker carpet, results are more variable and may require extra passes.
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.
On hard floors, reviews report very good pickup of pet hair, crumbs, and dust for everyday cleaning. Fine dust performance is generally praised, especially when paired with consistent scheduling.
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-wrap resistance earns positive mentions, with the anti-tangle brush design handling pet hair well in many tests. Some routine brush checks are still recommended, but tangling appears less frequent than on basic rollers.
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.
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.
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.
Innovation is supported by unique-fragrance coverage, CES recognition, in-robot cyclone discussion, and reviewers calling the system advanced or distinctive.
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.
Its relatively low profile (often cited around 9.6cm / 3.77in) helps it slip under more furniture than taller bots, improving day-to-day coverage in living rooms and bedrooms.
Low-profile evidence is limited to one review saying the robot fits under most furniture.
Maintenance is moderate: auto-empty reduces daily chores, but owners still need to wash/replace the mop pad, clean brushes/filters, and periodically check sensors. The simpler mop system shifts some upkeep back to the user.
Maintenance is a key strength. Reviewers cite minimal maintenance, months before real attention, easier upkeep, cleaner filters, and less need to intervene.
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 navigation are a highlight in most reviews, with the app map described as accurate and efficient for room-to-room coverage. Users report reliable route planning and useful scheduling/zoning, helping it keep floors tidy between deeper cleans.
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.
Mop lifting is strongly supported by multiple reviews, including automatic mop lift, carpet-wetness prevention, and 28 mm lift claims.
Mopping is generally rated as good for upkeep and everyday grime, but the system is simpler than flagship bots: a single flat pad, smaller onboard tank, and no dock-based pad washing/drying. Expect effective light mops, with more effort needed for dried-on messes and periodic manual pad cleaning.
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.
Noise is mixed: several reviews describe louder operation than quieter premium models, especially on higher suction settings. It is generally tolerable for daytime cleaning, but can be noticeable in smaller homes or when running near people.
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.
Obstacle/object avoidance is a common weak spot. Multiple reviews mention it can struggle with small clutter (like socks or low items) and benefits from pre-tidying, making it less set-and-forget in busy rooms.
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.
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.
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.
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.
Pet owners generally find it effective for keeping up with hair and tracked-in debris, helped by solid suction and anti-tangle design. It works best as a frequent-maintenance bot rather than a once-a-week deep clean for heavy-shedding homes.
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.
Value is a major selling point in reviews: it is often framed as a budget-to-midrange option that delivers strong cleaning and mapping for the price. The tradeoff is fewer premium automation features (like advanced obstacle avoidance or mop-wash docks).
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.
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 in default modes is typically sufficient for routine whole-home maintenance in small-to-mid spaces, with most reviewers implying it completes normal schedules without frequent interruptions.
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.
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 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.
Stuck resistance is average: it handles common thresholds and room transitions, but small clutter and cords can still cause interruptions. Prepping the floor improves consistency.
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.
Reviews consistently describe strong suction for a mid-tier robot (often citing 8,000Pa), with very good pickup on hard floors and low-pile rugs. Performance is solid for daily maintenance, but it is not positioned as a deep-clean replacement for thicker carpet or heavy debris in one pass.
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.
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.
Support/reliability sentiment is mixed-to-positive overall: many report stable performance, while others mention occasional quirks or the need for troubleshooting. It does not stand out as the most robust support experience in the category.
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.
The low stance helps it reach under many beds/sofas for routine pickup, though very low-clearance furniture can still be a limitation depending on leg height and clutter.
Under-furniture pickup is supported by one hands-on review saying the robot got into tight spaces under cabinets and under a bed.
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.
The onboard water tank is sufficient for light maintenance mops rather than heavy scrubbing sessions. Several reviews highlight the absence of a large dock water system, so refills and pad care are part of ownership.
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.
