Compare 3i G10+ Robot Vacuum and Mop Combo vs Eufy S2 Omni

Included extras are solid for a flagship robot vacuum, with reviewers noting cleaning solution, fragrance modules, documentation, and extra dust bags in the box.

The S2's chassis-lift feature is repeatedly presented as a major upgrade for plush rugs, thresholds, and higher-pile carpet handling.

No summary yet.

Reviewers generally liked the modern, visible-tech design, translucent top, lighting, and premium styling, though the dock can be taller than some alternatives.

Software and AI features are frequently highlighted (AI auto modes, object recognition, dirt-scan style behavior), though real-world consistency varies and some camera/object recognition features are described as limited by image quality.

AI navigation, 3D mapping, floor-type recognition, and app controls are useful, but the deepest independent test found app customization and smart-home integration behind rivals.

Area rug handling is a notable strength in several reviews, with the S2 lifting, avoiding tassels, and preventing rugs from bunching or getting pushed around.

Setup is broadly described as quick and beginner-friendly: plug in the dock, connect in-app, update firmware, and map the home with minimal hassle.

Setup is consistently described as simple, with the app and base display guiding pairing, mapping, and first cleaning with little friction.

At least one review highlights the robot stopping when it encounters problematic items (like cables), suggesting it can prevent motor damage during obstruction events.

Battery life is generally described as strong for the class, often sufficient for full-floor cleans without mid-run recharging, depending on home size and settings.

Battery comments are mostly positive, but measured coverage varies sharply by suction level and real-world recharge time can be long.

A large onboard dustbin is a key differentiator, repeatedly noted as bigger than typical robot bins and central to the small-footprint concept.

The dustbin and bag system benefits from automatic emptying and strong dock suction, reducing hands-on bin work.

Build quality impressions are positive, with reviewers calling the construction solid and the overall package premium.

High-pile and thick-rug handling is a split point: several reviewers praised climbing and deep cleaning, while one lab-style test found carpet agitation underwhelming versus rivals.

No summary yet.

Low/mixed carpet pickup is usable, but independent testing found it did not clearly outperform cheaper Eufy models or the older S1 Pro in deep-clean scoring.

No summary yet.

Medium-pile carpet evidence is limited but positive, with one review citing solid medium-pile results.

Child lock exists on the station controls, though one reviewer noted it can reduce the touchscreen's practical usefulness.

Cyclonic separation and filter cleanliness are strong recurring themes, with reviewers finding suction stayed strong and filters avoided clogging.

Comparisons are mixed: the S2 improves on some Eufy weaknesses and beats some rivals in specific tests, but other flagships remain stronger for carpet, mopping feel, or value.

App controls and UI are repeatedly described as straightforward and feature-rich, including mapping tools, room controls, and customization; some compare it as slightly behind top-tier brands but still strong.

The app and station controls are generally easy to use, with clean navigation and touchscreen controls, but advanced customization is not class-leading.

Edge and corner cleaning is a highlight due to an extendable side brush; most reviews praise edge reach, though one notes some leftover debris at corners.

Corner cleaning benefits from an extending side brush, though independent tests suggest the robot can still leave perimeter gaps depending on the run.

Groove and crevice evidence is positive for cracks but mixed for grout, where one test removed only part of the residue.

Cyclone performance is one of the clearest strengths: multiple reviewers praised multi-cyclone separation for maintaining airflow and keeping filters cleaner.

Dirty-water sensing evidence comes mainly from the dock's intelligent dirt detection, which can trigger additional washing or cleaning when water is dirty.

Docking reliability can be problematic on medium-pile carpet for some reviewers; placing the dock on hard floors is repeatedly suggested as the more reliable setup.

The dock is a major strength, handling auto-emptying, mop washing, drying, refilling, and hair-heavy debris with few clog complaints.

Dried-on stain removal is usually good for normal household stains, though heavy grout or extreme dried-mud testing is less certain.

Everyday use is easy, with scheduling, automatic routines, and low-touch maintenance repeatedly mentioned as benefits.

Edge and baseboard mopping is mixed: some reviewers liked the extending roller, while the most critical tester found visible wall gaps.

Edge-following behavior is generally praised for getting close to baseboards/edges, helped by the extendable brush and the mop extension mechanism.

Edge-following accuracy is one of the weaker areas, with independent testing saying it rides too far from walls and sometimes avoids edges inconsistently.

Onboard dust compression is widely praised for reducing emptying frequency and enabling a compact, charge-only dock instead of a bulky auto-empty base.

Dust containment and filtration are strong, with filters repeatedly staying clean after weeks of use and cyclonic separation keeping fine dust away from airflow.

The floorhead design stands out for its wide roller mop, extending mop head, and dual-brush anti-tangle layout.

Hard floors can look clean and shiny after mopping, though this evidence comes from one strong hands-on review.

Fresh wet-mess pickup evidence is positive in tomato sauce testing, where the robot picked up the mess without smearing.

Hair-removal channel behavior is positive overall: reviewers reported no tangles and center-channel hair removal working as intended.

Hair pickup on carpets is mixed: some reviewers report strong everyday results, while others (including lab notes) mention pet hair can be pushed around or not fully removed on certain carpets.

Hair pickup on carpets is strong when the priority is hair management, even if carpet agitation is not always class-leading.

Hair pickup on hard floors is consistently praised, with multiple reviewers noting noticeably cleaner floors after runs, especially in pet homes.

Hard-floor hair pickup appears strong, with reviewers finding minimal buildup on the roller after cleaning.

Tangle resistance is generally decent but not perfect: several reviewers mention the comb helps, yet some tangles still occur, especially without a conical/split roller design.

Hair-wrap resistance is one of the strongest consensus wins, especially for long-hair and pet households.

Fine dust pickup on hard floors is strong, including cocoa powder and fine-particle references, with no visible residue in several tests.

Large debris intake is strong on hard floors and mixed surfaces, with reviewers citing immediate pickup and good handling of cereal-like debris.

Lighting evidence is limited but positive, with one reviewer noting a light for dark areas and tight spaces.

The station's heating functions are strong, with hot-water mop washing and hot-air drying repeatedly called out.

Reviewers treated the S2 as innovative thanks to the fragrance system, cyclonic airflow, roller mop, and award/first-look attention.

Kid-friendliness is supported mainly by chemical-free sanitizing and cleaner floors for children or pets, not by child-specific controls beyond lockout.

Large debris handling is generally strong, with cereal, candy, and heavier debris picked up well in multiple tests.

Height is a limitation for some homes: multiple reviews note it may not fit under lower-clearance furniture due to its taller top housing.

Low-profile performance is positive for the robot body, which can fit under beds or tighter furniture better than some taller models.

Maintenance is a notable tradeoff versus premium docks: users often mention manual mop pad cleaning, occasional brush hair removal, and refilling the small water tank.

Maintenance needs are low overall thanks to the dock, cyclonic filter, and anti-tangle brush, though roller-tray buildup and tank rinsing still matter.

Maneuverability is generally smooth, with one reviewer praising movement quality and another noting mapping/path quirks around obstacles.

Navigation and pathing are generally described as efficient with good coverage; one review references high coverage metrics, while others note it maps thoroughly (sometimes slowly).

Mapping is fast and detailed, but path efficiency is not perfect in obstacle-heavy testing.

Mop lift is commonly cited as a useful feature for avoiding wet carpets, but lift height and overall mop system remain “basic” compared to higher-end self-washing or spinning/roller mops.

The mop-lift system is a major strength, with 28 mm lift and carpet avoidance repeatedly mentioned, though one review wished for a mop cover.

Mopping is usually rated as decent for maintenance and edges but not a deep-scrub solution; several reviews call it weaker than the vacuuming side and recommend more advanced mop systems for heavy mopping needs.

Mopping is one of the best-supported strengths, especially on hard floors, visible stains, and everyday LVP/tile cleaning.

Noise feedback is mixed: some reviewers call it quiet, while others describe it as louder than expected or having an unusual whirring tone that could bother noise-sensitive users.

Noise is a drawback: reviewers measured or noticed above-average sound, especially on maximum suction.

Obstacle avoidance is mixed: some reviews call it impressively capable for the price, while others report hit-and-miss behavior, especially with low/flat objects and certain household items.

Obstacle avoidance is useful but not flawless; some reviewers saw excellent avoidance, while independent testing found everyday clutter still gets pushed.

Odor control considerations come up mainly around mopping: without a self-wash/dry dock, users note you must clean/dry the mop pad to avoid smells after runs.

Odor control is polarizing: the dock sanitation and fragrance can help, but some reviewers found the scent too weak to matter.

Overall cleaning convenience is high because the dock, mapping, self-cleaning mop, and scheduled operation reduce hands-on work.

Longevity evidence is positive, centered on sustained suction, clean filters, and claims/tests showing no quick performance drop.

Overall opinion is favorable but nuanced: most reviewers praised the S2, while the strongest independent review framed it as specialized rather than universal.

Packaging evidence is brief but positive, with one reviewer saying everything was well packed.

Pet-oriented benefits show up frequently: strong hard-floor hair pickup, good coverage, and obstacle avoidance that can help in kid/pet clutter—though carpet hair pickup can vary by surface.

Pet-readiness is supported indirectly through hair management, pet waste avoidance, pet hair pickup, and odor/sanitation features.

Consistently positioned as standout value in the budget bracket, frequently noted as punching above its price with strong features and performance for the cost.

Price and value are the clearest caveats: several reviews noted the high $1,599.99-class price and questioned value versus cheaper or competing models.

Camera-based features (like video monitoring or object photos) are mentioned, but image clarity is sometimes described as limited, which can reduce usefulness and may raise privacy considerations for some buyers.

Privacy evidence is limited but positive for buyers who dislike camera-style monitoring, since one reviewer noted there is no video monitoring mode.

Measured/real-world runtime impressions are positive overall, with multiple reviewers noting it can complete cleaning cycles in typical homes; performance varies by suction/mop settings.

Runtime is adequate but context-dependent; coverage can be large on low suction and much lower on max suction.

Some reviews note UV-based sanitation inside the dust bin as a hygiene feature, intended to reduce bacterial growth while debris sits in the bin longer.

Sanitizing performance is widely emphasized, especially electrolyzed or ozonated water and claimed 99% to 99.99% bacteria/pathogen reduction.

Self-cleaning is a core strength: the roller cleans in real time and the dock washes, dries, and prepares the mop after runs.

At least one review references improvements through software/OTA updates, suggesting ongoing updates can meaningfully change real-world behavior over time.

Software support evidence is positive but early, with one pre-production reviewer seeing frequent firmware fixes.

The liquid system is advanced, with auto detergent, clean/dirty water handling, and electrolyzed water.

Storage footprint is mixed: the station is narrow or compact to some reviewers, but taller and more wall-space-hungry to another.

Streaking feedback is mixed: some reviewers report even, non-streaky results, while others describe streaks or uneven pickup, especially on tougher messes.

Streaking and residue performance is strong in most hard-floor tests, with reviewers repeatedly reporting no visible streaks, residue, or smearing.

Stuck resistance is mixed: some reviewers report it rarely/never got stuck, while others saw it climb onto objects, wedge itself, or struggle in certain obstacle scenarios.

Stuck resistance is positive on thresholds, rugs, and obstacles, though not every obstacle-avoidance test was flawless.

Vacuuming performance is repeatedly described as strong for the class, with effective pickup on hard floors and generally solid carpet pickup, though some tests and users note only average real-world results on carpet.

Suction and airflow are major strengths, with 30,000 Pa, 100 air watts, and sustained airflow repeatedly highlighted.

Heavy-duty suitability is good but not absolute; it can tackle demanding rugs and heavy use, but sustained max boost and deep shag can still be caveats.

Support and reliability are mixed: firmware updates were active, but a preorder recall and short warranty caveat reduce confidence.

Under-furniture pickup is limited by the robot’s height; it may miss spaces under furniture with low clearance.

Under-furniture pickup is positive, with reviewers saying it fits under most furniture and cleaned under beds that prior robots missed.

Value-for-money is mixed: the S2 is premium and capable, but reviewers questioned whether it justifies its price over Eufy's cheaper models or other flagships.

Versatility is strong across vacuuming, mopping, carpet adaptation, hard floors, thresholds, schedules, and multi-room cleaning.

The onboard water tank is frequently described as small, often requiring refills for regular mopping sessions, which limits hands-off mopping convenience.

Water tank usability is mostly good, with clear clean-water visibility and large reservoirs, though dirty tanks can develop odor without rinsing.
