One review says Dyson does not include spare rollers, brushes, or other ancillaries in the box.
Reviews mention a well-equipped ecosystem with included consumables (bags/cleaning tools/solution) and optional accessories like a hair-cutting roller. Add-ons can improve hair handling but can also add to ownership cost.
Positive reviews say it handles thresholds and floor transitions confidently.
Design is generally seen as sleek or attractive, even if it is less visually distinctive than older Dysons.
Design opinions are mixed: at least one reviewer says the dock looks dated or appliance-like compared with newer, more aesthetic competitors. Most other reviews focus more on function than finish.
AI and automation are central to the product and generally work, though real-world stain detection is not universally convincing.
Automation is a major theme: reviewers cite advanced obstacle avoidance, dirt detection with extra passes, customizable schedules, no-go zones, and pet-focused modes. The tradeoff for all that power is a larger settings surface area, and some reviewers find the app experience less polished.
Rugs and mixed floor transitions are a strong point in supportive reviews.
Carpet and rug handling is often praised because the robot can lift the mops and, in some modes, leave mop pads at the dock to avoid wetting textiles. A dissenting note is that mop hardware can still catch on some carpet edges or that pad removal is not always automatic, so settings matter.
Setup is a consistent strength across written and video reviews.
Setup is generally described as quick, with guided app onboarding and fast mapping runs. Reviewers report it is straightforward to get from unboxing to a usable map.
Battery life is good enough for many homes, but some tests say it still trails top rivals.
Battery life is described as long, with a large battery (often cited as 6,400mAh) and support for recharge-and-resume. Reviewers generally expect it to handle larger homes, though thorough mop routines can still take time.
Multiple reviews highlight the bagless bin and dock design as a standout convenience.
The dock uses a large disposable dust bag (often cited as 3.2L), reducing how often you deal with dust. However, some reviewers note bag replacement frequency and bag pricing can vary with usage and contribute to ongoing costs.
Reviews that discuss build quality largely call the robot well-made or solid.
Only a few sources discuss durability directly, but the comments that do are positive, noting robust wearing parts and a generally well-built feel. No review in the file reports major structural failures.
High-pile carpet results are split sharply, with one review praising deeper-shag boost behavior and another measuring poor dense-carpet pickup.
At least one review notes noticeably strong performance on thicker or higher-pile carpet due to high suction. Keeping carpets dry is helped by vacuum-only modes, mop lifting, or leaving mop pads at the dock, but some testers still caution about mop height when crossing carpet edges.
Low-pile carpet pickup looks middling in the dust-mat test that measured it.
On low-pile carpet, multiple sources report strong pickup and good deep-clean behavior, though stubborn pet fur may require repeat passes. Overall performance is consistently above average for a robot vacuum-mop.
For embedded debris in carpet, test-driven reviews report above-average deep-clean performance and strong suction delivery. Carpet deep-clean scores are described as near the top tier of current robot vacuums.
A child lock is mentioned as available, helping prevent accidental starts or setting changes. It is treated as a nice-to-have safety feature rather than a core performance driver.
One lab review reports no noticeable hairballs or tangles in the brush roll.
Hair-cutting and brush-lifting behaviors are cited as practical ways to prevent gunk and tangles, especially when the robot encounters wet patches. Reviewers generally frame these as helpful for keeping the cleaning path cleaner and reducing manual cleanup.
Comparisons are mixed; Dyson beats some rivals in speed or intelligence claims, but loses to others on cleaning or value.
In comparisons, the X40 Ultra is often positioned as a top performer, earning high marks for vacuuming, mopping, and obstacle avoidance versus other flagships. A few reviewers note that the very best competitors are close, so the final choice can come down to price and preferred features.
App experience is mixed: some call it intuitive or fluid, while others find it feature-light, patchy, or unintuitive.
The app offers deep controls (maps, zones, schedules, no-go lines, and automation toggles), and many reviewers find it powerful. A recurring downside is UI complexity: some call it clunky or overwhelming until you tune settings.
Corner cleaning is generally helped by the side systems and shifting brush behavior.
Corner cleaning is repeatedly praised thanks to an extendable side brush and edge-focused routines. Reviewers describe better corner reach than robots that rely on a fixed brush setup.
One test-focused review says groove and joint pickup on hard floors remains incomplete.
One review specifically highlights Dyson's cyclone-powered dock emptying system.
The dirt-illumination feature is repeatedly framed as a useful aid for spotting debris.
Some reviews highlight a dirty-water sensing approach that can trigger extra mop-pad washing or a second cleaning pass when the system detects heavier soil. This feature is presented as a meaningful upgrade for messier kitchens and high-traffic areas.
Docking and auto-empty reliability are mixed: some praise the dock design, others report missed emptying or docking struggles.
Docking and auto-empty are generally described as reliable, with a full-service station that empties dust and maintains the mops. One review flags weaker auto-empty suction and higher bag usage than expected, so performance may vary by debris load and settings.
Dock-related cleaning and drying noise is a common complaint.
It can remove dried-on stains, but not always in one pass and not every reviewer was impressed.
Dried-on mess performance is a standout: multiple reviews describe the spinning mop system and extra-pass behaviors as excellent on sticky or dried spills (such as coffee). It is frequently positioned as among the best moppers in its class.
One reviewer explicitly says the robot is easy to set up and use.
Ease of use is generally high once set up, with strong automation and helpful app guidance. The main usability complaint is that the app and feature set can feel complex at first.
Edge cleaning is mixed; some praise wall and skirting-board performance while others say edge pickup lags.
Edge and baseboard cleaning is a consistent strength thanks to an extending mop pad and edge-reaching behaviors. Multiple reviewers highlight noticeably better along-the-wall pickup compared with robots that cannot extend to edges.
One review says the robot traces room outlines methodically before cleaning rows.
Emptying is convenient when it works, but several reviews mention overflow or docking and evac inconsistencies.
Filtration is a weak point in the teardown-style reviews, which question both performance and how clearly Dyson specifies it.
One test-focused review notes that after cleaning wet spills the floor was not left overly damp, suggesting good water control. In general, the spinning mop system aims to clean effectively without soaking floors.
The brush and roller hardware gets praise for features like a shifting brush bar and V-shaped bristles.
One video test shows sticky liquid messes being picked up very quickly in the cleaned area.
Carpet hair pickup can be good, but it is not backed by as many reviews as other categories.
Carpet hair pickup gets conflicting feedback: some coverage labels it a top option for homes with pets, but at least one lab-style test found only average fur removal in a single run. Multiple passes, higher suction, and the right brush can matter here.
Hair pickup on hard floors is strong in the reviews that tested it.
Hair pickup on hard floors is mixed: some reviewers call it excellent for pet hair, while at least one test-focused review found it left a meaningful amount behind without multiple passes. Expect best results with tuned settings and the right brush configuration.
Anti-tangle performance is mixed: some reviewers saw little wrapping, while others had to clear hair or use scissors.
Tangle resistance is also mixed: long hair can still wrap around the main roller in some reports, but anti-tangle side-brush design and optional hair-cutting rollers are described as effective upgrades. Cleaning hair out is generally considered manageable.
Fine-dust results are mixed across reviews, ranging from excellent lab pickup to poor deep-dust tests.
Hard-floor fine debris pickup is described as excellent, with test-style reviews reporting near-perfect results on materials like sand. It is regularly characterized as thorough on hard surfaces.
Hard-floor large-debris pickup is usually strong, especially in real-home crumb and oat tests.
Large-debris pickup on hard floors is generally strong, with high percentages reported in testing and good real-world pickup. A minor recurring note is that a single pass can miss a few crumbs, which is solvable with extra passes or higher settings.
The green light and illumination feature is repeatedly mentioned as useful for spotting dirt ahead.
A heated mop-wash is repeatedly mentioned, with hot water used in the dock to clean mop pads and the washboard. Reviewers connect the heating to better mop-pad cleanliness and reduced odor.
Some reviewers see the dirt-detection approach and floor transitions as genuinely distinctive, while another says it still does not out-innovate the field.
Innovation shows up in features like leaving mop pads at the dock, lifting brushes when sensing liquid, edge-extending mops and brushes, camera-assisted stain attention, and sensor-driven re-cleaning. Reviewers frequently call these capabilities differentiators versus simpler robot vacuum-mops.
One lab review says it can miss a few larger crumbs near bowls or thresholds.
Its height is a recurring weakness, especially under cabinets and furniture.
Maintenance is not fully hands-off; some reviewers call out manual cleanup or weekly checks.
Maintenance is described as low day-to-day because the dock empties dust and washes and dries mop pads automatically. Owners still need to refill clean water, empty dirty water, replace bags, and occasionally wipe sensors and check brushes.
Positive tests describe the robot as moving smoothly across different floor types and obstacles.
Mapping speed is a major strength, though not every map is perfect or doorway detection flawless.
Navigation and mapping are repeatedly described as top-tier, with fast mapping and strong coverage efficiency. Some testers note occasional pattern quirks, but overall it is seen as reliable at completing whole-home cleans.
Mop lifting behavior exists, but not every reviewer finds it flexible enough in mixed-floor situations.
The mop system can lift during carpet detection and, in some workflows, leave mop pads at the dock to keep rugs dry. Most reviewers view this as a major advantage, though one notes the lift height may still snag on some carpet edges.
Mopping is above average overall, especially on fresh sticky messes, but some tests show misses or only partial stain removal.
Mopping is widely rated as a top-tier strength, driven by spinning pads, edge extension, and options for extra passes on dirtier areas. Some reviewers caution that the most aggressive automated modes can be overkill on delicate finishes until tuned.
Cleaning runs can be quiet enough for normal activity, but dock drying and self-empty cycles are notably louder.
Noise is acceptable on lower settings but becomes noticeably loud at maximum suction, which some reviewers frame as the cost of stronger vacuuming. One lab-style test measured it as louder than average, and reviewers recommend scheduling loud runs when you are out.
Obstacle avoidance is one of the more consistently praised robot traits.
Obstacle avoidance is one of the most consistently celebrated strengths, with multiple sources citing camera and structured-light sensing and near-perfect avoidance results. Cables can still be a challenge for any robot, but overall confidence is high.
Heated drying and roller cleaning are described as helping prevent smells.
Odor control is generally praised because the dock both hot-washes and hot-dries the mop pads, reducing musty smells. This is repeatedly mentioned as helpful for keeping the system from getting funky between cleanings.
Bagless operation is repeatedly cited as reducing ongoing costs compared with bagged rivals.
Running costs come up as a concern in some coverage, mainly around disposable dust bags and other consumables. Reviewers recommend factoring consumables into ownership cost, even if day-to-day maintenance is low.
Day-to-day convenience is a recurring positive theme, with reviewers describing less oversight and lower mental load.
After two months of use, one reviewer says the mop still looked brand new.
Overall sentiment skews positive, but several reviewers stop short of calling it class-leading.
Overall sentiment is strongly positive, with several sources ranking it at or near the top among flagship robot vacuum-mops. The most common reservations are the high price, the size of the dock, and mixed reports on pet-hair pickup consistency.
Pet-home suitability is supported by explicit pet-home framing and by cleanup results in homes with cats or dogs.
Pet-oriented features are a highlight: reviewers mention pet zones, avoidance of bowls and toys, and camera-based monitoring (including two-way video in some coverage). Performance with pet hair is more mixed, but overall the feature set is considered very pet-friendly.
Value is mixed; some say the performance or pricing is justified, while others say rivals undercut it or the price feels high.
Price is the most consistent negative: several reviews describe it as a premium, top-of-the-market model. Many still consider the performance and automation strong enough to justify it for the right home, especially when discounted, but value is weaker for budget shoppers.
Privacy gets limited but notable mention: Dyson says footage stays on-device, but the app still asks for permissions.
Runtime is usually described as solid to good, with enough coverage for many homes.
Sanitizing claims are tied mainly to the dock washing mop pads with very hot water (often stated around 158F). Reviews treat this as a hygiene win for the mop pads, not a guarantee of disinfecting the entire floor.
Self-cleaning is a clear feature advantage, but roller washing is not flawless in every test.
The dock self-cleans and maintains the mopping system by washing pads and the washboard and drying with hot air, often with scrapers and repeat-clean logic. This is repeatedly credited for reducing hands-on upkeep and improving hygiene.
The heated-water and solution system is useful, but several reviewers complain detergent is not included or note design compromises.
The solution system is frequently mentioned but described differently across sources: it can wash pads with detergent and, in some coverage, dispense floor-cleaning fluid. At least one reviewer notes detergent may be used mainly for mop-pad washing rather than being mixed into the floor water by default.
One review explicitly says the robot still cannot tackle stairs, making it poor for that use.
Several reviews call the dock and robot bulky and space-hungry.
Multiple reviewers call out the dock as large and space-consuming, even if the footprint is described as relatively slim in one write-up. Plan for a dedicated spot, especially if you are in a small apartment.
Roller-based mopping is often praised for avoiding smear and residue.
Residue and streak control depends on settings: reviewers mention choosing mopping direction or dialing back aggressive modes to avoid over-mopping certain finishes. When configured, most describe clean results without problematic streaking.
Stuck resistance is strong in some homes, but one reviewer reports it getting trapped under low furniture.
Reviewers report good stuck resistance, including handling taller thresholds (often cited around 22mm) and completing coverage without frequent rescues. As with most robots, extreme clutter can still cause interruptions, but it is rated highly here.
Reviews mostly describe suction as strong, though one test-heavy review says it falls well short of older Dyson standards.
Across reviewers, suction is repeatedly described as flagship-level, with strong debris pickup on both hard floors and carpets. Several sources cite 12,000Pa suction and top-tier vacuuming results, though max power can be loud and auto-empty strength at the dock is not praised by everyone.
One review warns apartment dwellers and homes with limited floor space to think carefully before buying.
One review notes Dyson's Concierge option for live video support during setup.
Under-furniture reach is a clear weakness for homes with toe-kicks, low beds, or low cabinets.
Under-furniture performance is frequently highlighted, especially around the base of cabinets and appliances where hair and debris collect. Extendable side reach behaviors help it pull debris from areas many robots miss.
At deal pricing it can make more sense, but at full price some reviewers still hesitate.
Reviewers describe it as a wet-and-dry or do-it-all robot rather than a single-purpose cleaner.
Reviews mention separate clean and dirty water tanks and straightforward tank handling.
The system relies on clean and dirty water tanks in the dock and an internal water tank in the robot, which keeps mopping more automated than vacuum-only robots. Expect periodic refills and dirty-water emptying, and some coverage mentions a future-leaning option for auto fill and drain via plumbing.
One hands-on video calls the robot heavy and cumbersome to lift.
