Pros
Sort
-
Suction is the S2’s clearest strength, with strong pickup across hard floors, rugs and embedded carpet debris. Multiple long-term tests also found that airflow stayed consistent as the bin and filter accumulated dust.
-
Mopping is the product’s signature strength, producing clean, streak-free hard floors with continuous fresh water and firm downward pressure. Difficult grout and severe dried stains can still require manual work.
-
Hair resistance is one of the strongest areas of agreement. The split DuoSpiral brush routinely finishes long-hair and pet-heavy cleaning with little or no wrapping.
-
The multi-cyclone system is a standout innovation, separating debris before it reaches the filter. It preserves airflow and keeps suction close to day-one strength through extended use.
-
The translucent top, glowing ring and slim tower give the S2 a distinctive premium look. Its design feels more like modern home technology than a bulky cleaning appliance.
-
The S2 earns broad praise for suction, mopping, hair handling and dock automation. Its premium price, inconsistent edge work and uneven navigation keep it from being the best fit for every home.
-
The UniClean station is consistently praised for reliable emptying, mop washing, drying, refilling and detergent dosing. It is among the most complete and dependable docks in the category.
-
Setup is consistently described as simple: assemble the ramp, fill the tanks, scan the app code and map the home. Most users can start cleaning within minutes.
-
Obstacle avoidance is usually excellent, including cords, pet waste and small household objects. A few tests still found collisions with dark items, toys or objects encountered immediately after a threshold.
-
Electrolyzed water, hot washing and continuous roller cleaning give the S2 unusually strong hygiene features. The system is especially appealing for homes with children or pets.
-
The fragrance system is polarizing: some homes noticed a pleasant, subtle freshness, while others could barely detect it. Dirty-water odors still require regular tank rinsing.
-
The app offers clear maps, schedules, room controls and adjustable cleaning settings. Core automation works well, although smart-home commands and advanced customization trail some rivals.
-
Cyclonic separation keeps the filters unusually clean and contains fine dust effectively. Several extended-use tests found little visible buildup or suction loss.
-
High-pile performance is much improved, with effective chassis lifting and strong suction on plush rugs. Deep agitation is not class-leading in every test, so carpet-focused homes should weigh that tradeoff.
-
Dried-stain removal is generally strong on everyday sauce, coffee, paw prints and jam, but tougher controlled tests produced mixed results. It is effective routine mopping rather than a guaranteed replacement for heavy scrubbing.
-
The S2 handles area rugs exceptionally well, climbing thicker piles while avoiding tassels and lightweight mats. It is less likely to bunch, drag or become trapped by rugs.
-
The automated dock, schedules, self-cleaning mop and reliable mapping make daily cleaning exceptionally convenient. Most routine work is reduced to servicing water tanks and consumables.
-
The roller is washed continuously while mopping and then cleaned and dried again at the dock. This keeps it fresh, reduces smearing and minimizes hands-on mop care.
-
The adaptive chassis lift is highly effective on thick rugs and carpet transitions. It raises the body, increases suction and reduces the chance of becoming stranded.
-
Carpet hair pickup is consistently strong, with excellent results on pet fur and long hair. The detangling design trades a little peak agitation for far less maintenance.
-
The 28 mm mop lift protects most carpets and supports mixed-floor cleaning in one run. Very thick carpet can still make light contact because the measured lift includes suspension travel.
-
Edge performance varies more than the central cleaning results. Some units clean close to baseboards, while others leave visible gaps because the robot rides too far from walls.
-
The robot and dock feel solid, well assembled and appropriately premium. Long-term testers reported no meaningful loss of structural quality.
-
Hard floors usually dry without visible streaks or residue. Controlled water output and the continuously cleaned roller leave a consistent finish.
-
The extending side brush improves corner pickup and often reaches debris that fixed brushes miss. Results depend on how aggressively the robot approaches the wall.
-
The dock display and app controls are clear, responsive and easy to understand. Angled controls and visible status information reduce the need to bend down or guess what the robot is doing.
-
The tall tower dock is narrower and easier to service than many wide stations, but it needs considerable vertical wall space. It works best where height is less restrictive than floor width.
-
Maintenance is generally low because the dock washes, dries and empties automatically, while cyclonic filtration keeps parts cleaner. Roller trays and dirty-water tanks still need periodic rinsing.
-
Mapping is fast and generally accurate, with useful 3D room and furniture recognition. Path efficiency is less consistent, and some tests found slower routes or unnecessary circling near complex edges.
-
Strong airflow reaches dust and litter in hardwood seams and floor grooves. This is a meaningful advantage on textured or imperfect hard floors.
-
Everyday use is straightforward once the home is mapped. Clear controls, scheduling and extensive dock automation let the robot operate with little supervision.
-
The continuously cleaned roller is particularly effective on fresh spills because it extracts liquid instead of spreading it. Wet messes are one of the system’s best use cases.
-
The S2 maintained strong suction and cleaning consistency through weeks or months of frequent use. Its durable feel and low performance decay inspire confidence for long-term ownership.
-
Pet owners benefit from excellent hair pickup, minimal brush tangling and a dock that can move dense fur without clogging. The sanitizing mop system also suits homes where pets track in dirt.
-
The robot’s low body reaches beneath beds, chairs and many cabinets while continuing to navigate reliably. It performs useful cleaning in places that are awkward to reach manually.
-
The S2 works well across hard floors, short carpet, medium carpet and many rugs. Its vacuum-and-mop design makes it a strong all-rounder for mixed-floor homes.
-
Visible tank levels and app alerts make it easy to know when clean water is low or dirty water needs attention. This reduces interrupted cleaning sessions.
-
Fine-dust pickup is strong overall, helped by sustained airflow and effective filtration. Fast side brushes can scatter light particles on the first pass before the robot recovers them.
-
Low-pile carpet pickup is very good, including ordinary dust, crumbs and pet hair. It cleans these surfaces confidently without the mobility problems of the older model.
-
Medium-pile carpet pickup is consistently strong, including embedded dirt and pet hair. It performs close to the better carpet-focused robots in normal use.
-
The lifting chassis handles normal thresholds and thick rugs well, but unusual obstacles and very tall transitions can cause hesitation. Low furniture is another occasional trapping risk.
-
Large debris pickup is usually immediate and controlled, though some tests found cereal pieces scattered or avoided. A second pass may be needed for grouped bulky debris.
-
The dock’s disposable bag can hold roughly two months of debris, reducing how often it needs attention. That supports the S2’s hands-off appeal.
-
The multi-cyclone system prevents fine dust from rapidly clogging the filter. Suction stayed strong even after substantial debris collection.
-
The self-empty dock handles dense hair and packed debris without clogging in normal use. An overfilled bin may occasionally require a second empty cycle.
-
The app’s service timers clearly show when filters, brushes and other consumables need attention. This is easier than tracking maintenance manually.
-
Mopping left hard floors visibly clean, glossy and pleasant underfoot. The finish was especially impressive on kitchens, hallways and other high-traffic hard surfaces.
-
Hard-floor hair pickup is excellent, including long human hair and pet fur. The debris moves cleanly into the suction path instead of wrapping around the rollers.
-
The center hair channel works as intended, directing strands toward the suction port instead of trapping them. Test rollers remained nearly free of wrapped hair.
-
Heated mop washing and hot-air drying improve roller hygiene and reduce lingering moisture. The dock prepares a cleaner mop for the next run with little manual effort.
-
The built-in fragrance module and onboard multi-cyclone system distinguish the S2 from most competitors. Both features make the product feel genuinely different rather than merely more powerful.
-
The sanitized mopping system and strong avoidance of cords and household clutter make the S2 appealing for families. Cleaner floors provide extra reassurance where children play.
-
Movement is smooth and responsive, without the jerky corrections seen in some robots. It transitions through rooms and around furniture confidently.
-
Frequent firmware updates improved the pre-release unit and addressed reported quirks. Ongoing software refinement appears to be a meaningful part of the product’s support.
-
Automatic detergent dosing and controlled water delivery keep the mopping system supplied without manual measuring. The liquid system supports consistent cleaning across scheduled runs.
-
Cliff detection handled stair edges safely during testing. The robot navigated upper levels without attempting a dangerous drop.
-
The S2 handles mixed debris well, but grouped cereal and other bulky pieces can expose inconsistent approach behavior. Most remaining debris is recovered with additional coverage.
-
The package includes useful starter supplies such as cleaning solution, fragrance modules and a spare dust bag. The extras make the initial setup more complete.
-
Dirty-water sensing can trigger an additional cleaning pass when the extracted water remains heavily soiled. This adds useful automation for messier rooms.
-
Low-light operation is reliable enough for overnight or early-morning cleaning. The robot can navigate dark rooms without needing the household lights turned on.
-
The robot fits under most ordinary furniture despite its advanced sensors. Its low profile expands useful cleaning coverage in bedrooms and living areas.
-
The S2 handled tens of thousands of square feet and many hours of daily cleaning with little performance decline. It is well suited to frequent, demanding use.
-
Compared with its predecessor and current flagships, the S2 clearly improves hair handling and carpet mobility. It is less dominant in deep-carpet agitation, software features and value.
-
The water tanks are easy to access and generously sized, but heavy mopping can require refilling and emptying every few runs. Large single-floor homes may need more frequent tank service.
-
The floor remains lightly damp after mopping but not dangerously wet. Drying is reasonable for routine hard-floor cleaning.
Cons
Sort
-
The robot itself fits beneath much furniture, but the tall dock and occasional navigation trouble in tight nooks make it less ideal for compact homes. Small apartments may also find the system excessive.
-
The powerful fan can blow light hair or fine debris away before pickup. This was most noticeable with loose cat hair during controlled hard-floor testing.
-
Ownership costs can be high once replacement bags, filters, fragrance modules and heavier maintenance are considered. Budget-focused buyers may find simpler systems cheaper to run.
-
Repeatedly getting trapped beneath one console caused visible scratches on the front. Homes with low, tight furniture may need a no-go zone to protect the finish.
-
The robot is acceptable on lower settings but becomes noticeably loud at maximum suction. Buyers sensitive to noise will likely prefer scheduled daytime runs or reduced power.
-
Edge-following accuracy is inconsistent, with some runs leaving an obvious perimeter gap. More app control over wall distance and brush deployment would improve results.
-
Cloud-dependent integration limits fully local privacy and control. Native Matter support provides a partial workaround for smart-home users.
-
Reliability is mixed: firmware support has been active, but early recall concerns and occasional app disconnects temper confidence. The short warranty also feels conservative for such an expensive machine.
-
Battery performance depends heavily on suction mode, and maximum power sharply reduces coverage. Recharge times around five hours are slow for a flagship robot.
-
Value depends strongly on priorities. It makes sense for frequent hard-floor mopping and heavy hair, but cheaper robots can match parts of its performance with less maintenance.
-
Child lock is useful for preventing accidental dock commands, but it also limits the convenience of the touchscreen. Households with children may rely more heavily on the app.
-
Runtime ranges from adequate to disappointing depending on power level. Large homes may see a recharge interruption, especially when maximum suction is used.
-
The flagship price is the most consistent hesitation. Strong cleaning and automation help justify it, but several less expensive robots deliver similar results in selected areas.
