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.
Design is frequently praised: the dock’s wood-look top and furniture-like footprint blend into living spaces better than many rivals. A minority dislike the faux-wood finish or find the dock less attractive in person.
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 and automation are feature-rich: schedules, zones, room-specific routines, dirt-prioritization, and voice assistant support are widely praised. Common nitpicks include occasional connectivity hiccups, confusing menu choices, and missing real-time map progress in some experiences.
Blowback and scattering are usually controlled, with some reviewers noting it avoids flinging small particles. However, the side brush can flick larger debris around, and a few tests report scattered grains on hard floors.
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.
Rug handling is usually good, especially because the retracting mop prevents wet pads from dragging onto carpets. Still, the mop arm can occasionally catch on rug edges/corners, and very thick or tricky rugs may need keep-out or no-mop zoning.
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 typically quick and well-guided through the app, with packaging and quick-start materials helping. Initial mapping can take multiple runs, and a few users report early hiccups aligning the robot on the dock or connecting to Wi-Fi.
The robot is described as responsive to obstructions, stopping or rerouting around people/pets and common objects. It’s not perfect in every edge case, but it tends to avoid creating bigger messes when something blocks its path.
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 strong for large-area runs, often finishing typical floors without intervention and returning to recharge as needed. Charging can feel slow for some users, but recharge-and-resume behavior is reliable in most accounts.
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 bagged dock system is praised for cleanliness and low-touch disposal, typically lasting weeks to around two months depending on shedding and home size. Internal bin is small but rarely needs manual emptying thanks to frequent auto-empty cycles.
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 generally described as solid with removable, serviceable parts. Some mention cosmetic scuffing during early mapping runs from gentle bumping, but no widespread structural issues are reported in these reviews.
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.
High-pile/shag carpets are a weak spot for the vacuum-only model in one review, with quick tangling/stalling in long fibers. For homes with lots of high-pile, expectations should be tempered or zones configured to avoid problem rugs.
Low-pile carpet evidence is limited but favorable, with one review summary calling short-pile carpet performance very good.
Low-pile carpet pickup is generally very good, handling daily hair and debris well. Some users still notice occasional leftover strands on rugs and may choose extra passes for a more thorough finish.
Medium-pile evidence is limited but positive, with one test summary calling medium-pile results solid.
No summary yet.
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.
Comparisons usually place the j9+/Combo j9+ among the best for vacuuming and obstacle avoidance, with advantages over older Roombas. Several reviewers note that top hybrid competitors can outperform it in deep scrubbing or self-maintenance 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.
Controls are straightforward: the app handles most functions, with a simple on-robot button for start/pause and basic status lights. Some reviewers wish for richer in-app live tracking and clearer guidance in the manual/owner docs.
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 a known limitation: as a round robot with a single side brush, it can miss tight corners or smear debris in corner flour-style tests. Edges and open perimeters are better than sharp corners.
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.
Crevice and groove pickup is repeatedly called out as improved versus older Roombas, aided by stronger suction and the dual rubber rollers. It performs well on seams and along transitions in testing.
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.
Auto-empty docking is consistently reliable, with the robot returning to empty and resume without much user intervention. Bagged disposal keeps the process clean, and many users report weeks of hands-free vacuuming before needing to swap the bag.
Dock emptying volume is inconsistent across reviewers: some describe it as very loud, while others find it comparatively quieter and less high-pitched than older Roombas. Either way, the empty cycle is brief and can be scheduled around quiet hours.
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.
For dried-on stains, SmartScrub/back-and-forth motions improve results and can remove many common spots like dried juice, litter prints, and tracked-in dirt. Very sticky food or heavy buildup may still require manual spot work or a pad change afterward.
Ease of use is supported by a reviewer calling the robot super easy to use in the context of common robot-vacuum challenges.
Day-to-day use is strongly praised once maps are set: scheduling, recharge-and-resume, hands-free emptying, and reliable obstacle avoidance reduce babysitting. Early learning runs can require a bit of attention, but it becomes largely set-and-forget.
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 cleaning is good for a round robot but not flawless: it follows baseboards well in open areas yet can leave debris along edges and misses some grime in tight perimeter spots, especially during mopping.
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.
App-based maintenance reminders for filters help keep performance consistent, with clear prompts on when to replace. Filters still require planned replenishment since they aren’t washable.
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.
Dust containment is generally solid, helped by a sealed, bagged dock and replaceable filters. Filters are not washable and need periodic replacement, but most reviewers report clean handling with minimal dust mess.
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 is strong in many reports, though a few users still see stray hairs on low-pile rugs and may prefer an extra pass for perfection. Overall it’s above average for daily maintenance.
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.
Hard-floor hair pickup is a consistent strength, especially for pets and long human hair. A few mention the occasional hair clump, but overall results are strong with minimal leftover hairballs.
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.
Dual rubber rollers reduce tangling compared with bristle rollers, and several reviewers report noticeably less hair wrap. Some periodic hair removal is still needed, especially in heavy-shedding homes.
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 is consistently reported as excellent, including flour/sand-style tests in some reviews. Multiple passes can further improve results, especially on carpet fine-particle stress tests.
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 is strong overall, though a few note the side brush can flick bigger bits around before they’re captured. In most homes it handles cereal, kibble, and tracked-in debris well, with occasional stragglers in corners.
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.
The combo design is seen as meaningfully innovative: the fully retracting mop arm reduces carpet-wetting risk, and the auto-fill dock adds true hands-free mopping convenience. It’s less novel on pad washing, where competitors often do more.
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.
The low-profile body helps it fit under more furniture than bulkier rivals, improving coverage in real homes. Dock size is still substantial, but the robot’s height is generally a plus.
Maintenance is a key strength. Reviewers cite minimal maintenance, months before real attention, easier upkeep, cleaner filters, and less need to intervene.
Maintenance is moderate: the bagged dock reduces daily hassle, but mop pads still require manual washing/swapping and parts like filters/brushes need periodic attention. Several reviewers call the pad-care step the main ongoing chore.
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 pathing are generally systematic and thorough, with efficient row cleaning once the home is learned. Initial mapping is sometimes slow or clumsy compared to LiDAR bots, and a few tests note slightly longer overall run times than some competitors.
Mop lifting is strongly supported by multiple reviews, including automatic mop lift, carpet-wetness prevention, and 28 mm lift claims.
The retracting mop mechanism is a defining strength, reliably keeping carpets dry by fully lifting/stowing the pad on top of the robot. It enables true vacuum-and-mop-in-one-run behavior without worrying about damp rugs.
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 generally effective for routine upkeep, with smart back-and-forth scrubbing helping on stains. It can struggle with sticky messes and heavy grime compared with spinning/vibrating pad competitors, and edges/corners remain challenging.
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 a mixed bag: in-room vacuuming is often described as noticeable but tolerable, while auto-emptying can be loud for some. A few reviewers found the empty cycle quieter than other robots, but others measured/mentioned it as disruptive.
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 defining strength: the camera-based system reliably dodges cords, toys, shoes, and pet waste in most tests, and often outperforms rival bots in clutter. It’s not flawless, but it dramatically reduces stuck events and accidental messes versus non-vision robots.
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.
Ongoing costs are a real factor: bags, filters, brushes, and occasional pads add recurring spend. The upside is the bagged system is clean and parts are widely available, but budget-minded buyers should plan for replenishment.
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 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 households benefit from strong poop/pet-waste avoidance, plus reliable hair pickup on hard floors and rugs. Multiple reviews highlight the pet waste guarantee as a key confidence booster in cluttered homes.
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 polarizing: most agree performance and automation are premium, but the MSRP feels steep and many recommend waiting for sales. Those upgrading from older Roombas or prioritizing obstacle avoidance are more likely to feel it’s worth the spend.
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.
Privacy controls are a recurring discussion point because the robot uses a camera for navigation and obstacle recognition. Reviews note opt-in options and iRobot’s stated controls/encryption, but some users may still prefer a non-camera approach depending on comfort.
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.
Runtime is generally strong for a premium robot, commonly around two hours in everyday use, with recharge-and-resume covering larger spaces. Expect longer total job times when both vacuuming and mopping, or when using max power/two-pass settings.
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.
Residue and streaking are usually minor, but some reviewers notice occasional streaks or sticky patches after messy tests like jam/jelly. Regular pad washing and appropriate water/solution settings help reduce visible 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.
Stuck events are infrequent once maps and keep-out zones are tuned, but the robot can still snag on bath mats, high-pile rugs, tight gaps, or situations where the mop arm can’t retract cleanly. Overall, it improves after the first few runs.
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 a standout: strong pickup on hard floors and carpet, with smart boost behavior and fewer repeat passes than older Roombas. A few testers still rate raw power a step behind the most aggressive premium competitors, but most call it top-tier for daily debris.
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.
Reliability feedback is mostly positive over weeks of use, but a few reviews mention glitches (unfinished jobs, mode misbehavior) and at least one report of a defective unit that required replacement. Keeping receipts for early runs is commonly advised.
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 reach is good thanks to the low profile and persistent navigation, with multiple reviewers noting it cleans under beds, desks, and tables. Very low clearances still depend on your furniture height.
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.
Auto-fill dock is a major convenience, with many citing weeks of mopping before refills in average use. A few find the reservoir awkward to handle/refill, but the concept and day-to-day automation score highly.
