Scorata scores summarize analyzed review evidence on a 1–5 scale; they are not laboratory measurements or a simple average of customer star ratings. Feature scores summarize the reviews covering that feature. The overall score averages feature scores within each review, then combines review averages. When both expert and customer evidence are available, those two groups receive equal weight. Products can have different review coverage, so small score gaps do not establish a winner.
Recommendations prioritize important features for the category, with a score of at least 3.5, a gap of at least 0.25 points and at least two supporting reviews per product. Features with widely varying scores or broad connectivity contexts are excluded from recommendations. These safeguards do not establish statistical significance.
Quick verdict
The review evidence points to a tradeoff: Suction and Airflow versus Mop lifting system and Edge and Baseboard Cleaning (Hard Floors). Choose according to which strengths matter more to you; the overall score alone does not settle that choice.

Scores are out of 5. Missing scores mean missing review evidence, not a missing feature.
Basic operation is easy once the map and floor are prepared, and app controls are straightforward. First-time setup guidance and separate vacuum/mop passes add some friction.
Ease of use was strong for basic runs but weakened by multi-floor remapping hassles and a critical review's frustration with errors.
There is no mop-lifting system. The wet pad must be removed for carpet vacuuming, making mixed-floor cleaning less automatic.
The mop-lifting and detaching system was widely praised for avoiding wet carpets and reducing manual intervention.
Dried-on stain removal is poor. The fixed pad can handle light maintenance wiping, but coffee, milk, juice, and muddy paw prints often remain.
Dried stain removal was one of the strongest themes, with multiple reviewers seeing it remove dried juice, coffee, soda, syrup, and hidden messes; one critic found coffee remained.
One reviewer found it capable on carpets of varied thickness, but this is less established than its low-pile performance. Homes dominated by plush carpet should be cautious.
Evidence on thicker or long carpet was weak, especially for kitty litter, hair, and oatmeal caught in longer fibers.
The robot maneuvered confidently over small thresholds, around furniture, and through tight turns. It also managed a chunky desk leg without becoming stranded.
Maneuverability and navigation were mixed, from confident obstacle handling to one review describing dock navigation as a nightmare.
Three water-flow levels provide useful control for light mopping on different hard floors. The system is simple rather than sophisticated, with no active scrubbing or automatic refill.
The liquid system drew a serious negative review because of leakage, saturation, and very wet floors.
The bagless base is easy to empty and reduces routine handling of the robot’s bin. Dumping the cylinder can be slightly messy, but the overall process is convenient.
Mess control was polarized: self-emptying was convenient, but reviewers also noted dust attraction, wet mop leakage, and no-fuss positives.
Carpet hair pickup is excellent, including long hair and pet hair. Controlled testing reported near-complete removal and strong real-world results.
Carpet hair pickup was mixed: one lab result was excellent, but other reviewers still saw cat hair or weak thick-carpet pickup.
The mop attachment can click in easily, but switching between vacuum and mop modes is not always intuitive. One reviewer found the dock-facing connection awkward.
Tool-change simplicity was strong in the setup video, where parts clicked and locked into place easily.
A dirty mop pad can drag residue across hard floors if it is not washed frequently. Larger areas may require multiple pad cleanings during one session.
Residue control was split, from syrup removal without residue to critical evidence of dirt being spread around.
Mapping is usually fast and cleaning paths are orderly, with efficient row patterns and strong coverage. Some homes experienced phantom rooms, upside-down maps, or indirect routes to selected rooms.
Mapping and pathing drew mixed evidence: maps could be accurate and routes orderly, but one-floor mapping, app limits, and follow-through issues hurt confidence.
It can free itself from some tight spaces, but clutter and narrow dead ends increase the chance of getting stuck. Floors still need preparation before unattended runs.
Stuck resistance was mostly strong in positive reviews, but one critical review found the mop pad could snag and jam.
There is no full-bin indicator for the robot’s internal dustbin. Pet hair can fill it before users realize it needs attention.
The base does not alert when the debris container is full, so the reviewer had to keep an eye on it.
Medium-pile and deeper carpet cleaning tested very well in the strongest reviews. Two-pass runs left heavily soiled carpet looking exceptionally clean.
One reviewer found the carpet looked refreshed after a pass, but carpet-specific evidence was otherwise more mixed by pile type.
Obstacle avoidance is basic: larger shoes and furniture are usually detected, but cables, socks, toys, and pet messes may be hit or swallowed. Unattended cleaning works best after tidying.
Obstacle avoidance was often strong, but headphones and a threshold jam showed that it was not foolproof.
Large hard-floor debris was handled very well in testing, with no major intake limitation reported.
Hard-floor large-debris pickup was strong in lab and home testing, especially Cheerios and dry oatmeal.
The onboard tank is reasonably sized, but several testers found it could run dry during larger jobs. It is easy to remove and fill, yet the lack of a low-water warning is frustrating.
Water tanks were praised for comfortable handling, but one critical review disliked the smaller dirty-water capacity.
It handles area rugs and carpet transitions well and can automatically avoid carpet while the mop is attached. The fixed mop means mixed-floor homes may still need separate vacuum and mop runs.
The Shark impressed reviewers on area rugs, with one review saying the rug felt cleaner and fluffier than with a Dyson stick vacuum.
The combination of strong suction, bagless auto-emptying, anti-tangle cleaning, and broad app controls feels advanced for the price. Its innovation is concentrated in value rather than premium mopping hardware.
Innovation was a highlight in positive reviews, though one critical review framed the design as an old system made to feel new.
Large debris pickup was strong in controlled testing, with the robot handling varied debris sizes across hard floors and carpet.
Large debris handling was strong on linoleum in Tom's Guide testing, especially with Cheerios.
Pet owners found it useful for daily litter and hair cleanup, and one tester’s cats tolerated it well. Its anti-tangle brush also reduces hair-related upkeep.
Pet-ready evidence was strong for pet hair and hidden pet-related messes, though carpet depth still affected results.
The low body reaches well beneath dressers and other furniture until the top-mounted sensor meets a height limit.
Under-furniture pickup was positive when the robot cleaned under a large storage bed.
It covers the everyday basics well: hard floors, low-pile carpet, pet hair, light mopping, room cleaning, and multi-floor maps. Its versatility is limited by the fixed mop and basic obstacle detection.
Versatility was praised for seamless switching among mopping, vacuuming, and combined cleaning modes.
The bagless auto-empty design is widely liked because it avoids replacement bags and makes collected debris visible. The tradeoff is a reusable filter that still needs cleaning, and the small onboard bin can fill quickly with pet hair.
Bagless storage and reduced bag costs were praised, while the onboard dustbin size and exterior dust attraction created some mess-control complaints.
Vacuum maintenance is modest because the base empties the bin, but the mop pad, filters, and brushes still need attention. The fixed mop may need washing every 15–25 square meters to avoid spreading grime.
Maintenance was helped by hands-free features and bagless ownership, but one critic recommended manually removing the mop pad to dry it.
Overall sentiment is strongly positive for vacuuming, automation, and value. Most reservations center on the basic mop, limited obstacle avoidance, edge cleaning, and slower charging.
Overall opinion was polarized: most professional and hands-on reviews were highly positive, while one owner-review was strongly negative at the price.
Runtime is long and easily covers many average homes on normal settings. Maximum suction and repeated passes drain the battery much faster.
Runtime was usually validated near the three-hour claim and enough for large main-floor sessions, except for one critic's battery-size concern.
Pet hair pickup on hard floors was described as effective, supported by strong suction and the anti-tangle brush.
Hard-floor pet hair pickup was excellent in Tom's Guide testing, with no visible hair left on linoleum.
Value is one of the strongest points, particularly when discounted or bought used. Buyers get unusually strong vacuuming and automation without paying flagship prices.
Value-for-money was sharply negative in one owner review that would not recommend paying the asking price.
Local brand support was viewed positively, with one panel highlighting solid backup from an established company.
Reliability concerns came mainly from a critical owner review that said errors showed up constantly.
Physical assembly is quick, but the instructions are too sparse for some first-time robot-vacuum owners. The mop setup in particular could use clearer diagrams or video guidance.
Setup was mostly easy in hands-on use, although one review treated the initial setup and mapping time as a noticeable process.
Reviewers consistently consider it excellent value, especially at sale prices. At full retail price, stronger premium models may become competitive.
Value was mixed: several reviewers thought performance justified the high price, while others called the price hefty or unacceptable.
Auto-emptying is usually reliable and highly convenient, and several testers saw the robot return and unload successfully. A minority experienced missed emptying or trouble locating the dock in more complex layouts.
The self-emptying dock was praised for reducing fuss, though navigation back to the dock could be inconsistent in one review.
Edge and baseboard cleaning is a clear weakness. The round body and fixed side brush leave a noticeable strip beside walls, doors, and closet tracks.
Edge and baseboard mopping was generally positive, with reviewers noting wall and cabinet edges received attention.
Mopping is suitable for light dust, fresh marks, and routine maintenance, not deep scrubbing. Reviewers consistently found it much weaker than the vacuuming performance.
Mopping performance was a major strength in most hands-on reviews, though one negative review found it left wetness and residue behind.
Corner cleaning is below average because the round body cannot reach square corners. A stick vacuum or crevice tool is still needed for trapped edge debris.
Corner and edge debris pickup was praised with the side brush and air nozzle, but a critical review said the lack of an extendable brush limited reach.
Its vacuuming performance often matches or beats more expensive budget-class rivals. Reviewers repeatedly described it as punching above its price tier.
Comparative evidence ranged from strong praise over a Dyson stick vacuum to criticism that Shark lagged stronger premium competitors in features.
Bagless ownership removes the recurring cost of dust bags, but the reusable filters require regular cleaning. Long-term costs should mainly come from brushes, filters, pads, and eventual battery wear.
Bagless operation was a clear ownership-cost advantage because reviewers emphasized not buying recurring dust bags.
Noise depends heavily on the setting: quiet mode can be unobtrusive, while stronger suction and the emptying cycle are noticeably loud. Light sleepers may prefer daytime scheduling.
Noise was a recurring concern, especially vacuum motors, auto-emptying, and water-wash cycles.
Suction is a major strength, with multiple reviewers finding it unusually powerful for the price. It handled dust, debris, and pet hair effectively across common floor types.
Vacuum suction and airflow were praised as superb or extremely effective in positive reviews, with carpet limitations showing up elsewhere.
The auto-empty cycle is louder than the robot at maximum suction, but it lasts only a few seconds.
Dock-related noise was mixed: auto-emptying and water washing were loud, while drying was described as a lower hum.
Daily cleaning is highly convenient thanks to scheduled runs, room controls, long runtime, and automatic emptying. Mop attachment changes and floor preparation prevent it from being fully hands-off.
Overall cleaning convenience was high in positive reviews, especially the ability to schedule, self-empty, and clean without intervention.
The app offers extensive control over maps, rooms, suction, water flow, schedules, and cleaning passes. The main interface complaint is that map orientation can be awkward or impossible to correct.
Controls and UI were split: some reviewers found the app simple, while others found map editing difficult, limited, or dated.
The app and automation package is a major strength, including room cleaning, no-go zones, schedules, multi-floor maps, recharge-and-resume, and voice control. It lacks camera-based AI object recognition.
Smart features were useful, especially app control and on-device AI, but the Shark app drew criticism for hidden, dated, or limited controls.
Battery capacity is generous, but charging is slow. A full recharge can take many hours, which matters when high suction interrupts a large cleaning job.
Runtime was usually enough for large cleaning sessions, but one critical review argued the underlying battery is small for a flagship robot.
Its low-profile body reaches under many beds, drawers, and cabinets. The raised LiDAR turret sets the final clearance limit.
The low profile helped the robot clean beneath a large storage bed.
The side brush was the main weak accessory, feeling fiddly and briefly detaching during a test. Once reseated, it stayed in place.
Reviewers generally liked the lift system for thresholds and obstacles, though one negative review found the mop assembly could still snag.
Low-pile carpet results are generally very good, especially with stronger suction or two passes. One panel found default settings weaker, so heavier debris may need a more aggressive mode.
The dock cord was criticized for limiting placement options.
UV and light-based stain visibility was repeatedly praised as useful or cool, although one reviewer called it somewhat gimmicky for everyday use.
Only one opinionated review addressed energy use, criticizing the robot as energy intensive during scrubbing.
The four-stage filtration system is praised for containing fine particles and allergens. Reviewers viewed it as a useful complement to the strong suction.
Floor drying was a weakness where wet mopping left floors damp for around 30 minutes or very wet in critical testing.
The main anti-tangle brush performs exceptionally well, with several tests showing little or no wrapped hair. The small side brush can still collect hair.
Fine dust pickup on hard floors is consistently strong. Reviewers found the suction effective on everyday dust and small debris.
The LED and color-light cues helped reviewers understand what the robot was doing during stains, dirt boosts, and errors.
Odor control was helped by a fresh-smelling deodorizer, while a critical review warned that a damp pad could create odor concerns.
Storage footprint was mixed: the dock needed significant clearance, but one reviewer still found it visually unobtrusive.
Heavy-duty suitability was limited because one reviewer still preferred a regular vacuum for deep cleans.
Small-space performance was helped by avoiding a narrow coffee table, though dock footprint and app handling of small rooms remained caveats.
The robot does not warn when the water tank is low or empty. Refilling mid-clean can interrupt the job and may force a restart.
Design impressions were mostly positive, with reviewers calling the dock refined or sleek despite its larger footprint.
Build quality was challenged by one critical review that called the mop pad toy-like and flimsy.
Floorhead design drew criticism for a weak single roller on thicker carpet and a flimsy, thin mop-pad structure in one negative review.
A critical review raised durability doubts around the thin mop-pad assembly.
The side air jet was praised as clever in one hands-on video, but other evidence found it could blow debris the wrong way or lag behind an extendable brush.
The bagless cyclone system is praised for maintaining strong suction while separating debris. It also eliminates disposable bags, though its filter still needs cleaning.
The robot's edge-following during mopping was praised for giving wall and cabinet edges similar attention to open flooring.
The app tracks estimated remaining life for filters and brushes, reducing guesswork around maintenance.
Floor shine was praised when mopping left hard floors sparkling.
Sanitizing evidence was limited and cautioned that UV light itself does not sanitize quickly during a pass-over.
The self-cleaning dock and mop cycle were praised for reducing manual fuss and restarting without user intervention.
Privacy controls received positive attention because stain-detection images are processed locally rather than sent to the cloud.
