One review says Dyson does not include spare rollers, brushes, or other ancillaries in the box.
Unboxings typically include the robot, dock, ramp, cord, and manuals, with a dust bag preinstalled. Multiple reviewers note that extra consumables (spare bags or detergent) may not be included.
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 and finish are consistently praised, with multiple reviewers calling the robot and dock premium-looking (brushed/metal-like textures and a sleeker base). Even reviewers with performance complaints tend to like the aesthetics.
AI and automation are central to the product and generally work, though real-world stain detection is not universally convincing.
The Ecovacs app is widely praised for organization and depth (routines, maps, barriers, dock controls), and multiple sources mention Matter and voice features (including Yiko). A few note that some settings are buried or that the robot can be overly chatty.
Multiple reviewers note reduced debris scattering compared with earlier models, sometimes crediting a slowed or redesigned side brush. Conversely, some negative experiences describe debris drops around thresholds or during return-to-dock events.
Rugs and mixed floor transitions are a strong point in supportive reviews.
Carpet detection is described as competent, but thick rugs and thresholds are recurring pain points in negative reviews. The robot is also described as limited to standard threshold heights rather than newer advanced climbing systems.
Setup is a consistent strength across written and video reviews.
Setup is often described as straightforward, but several reviews mention initial firmware updates, mapping hiccups, or time spent editing room divisions. Planning a little extra time for first-run mapping improves the experience.
Battery life is good enough for many homes, but some tests say it still trails top rivals.
Battery impressions are mixed: official low-power runtimes are strong, but measured testing and higher-power settings can look below average for efficiency and coverage per charge. Recharge-and-resume helps, and some reviewers still find it sufficient for typical homes.
Multiple reviews highlight the bagless bin and dock design as a standout convenience.
Several reviews note the robot’s internal bin is small for a flagship, increasing dependence on the dock. The dock’s disposable bag is described as large-capacity, but spare bags aren’t always included.
Reviews that discuss build quality largely call the robot well-made or solid.
High-pile carpet results are split sharply, with one review praising deeper-shag boost behavior and another measuring poor dense-carpet pickup.
Low-pile carpet pickup looks middling in the dust-mat test that measured it.
Carpet performance is frequently rated near the top, with strong deep-clean results and above-average pickup on rugs. Some comparisons still argue the X8 is close enough on most tests that the X9’s premium is hard to justify.
One lab review reports no noticeable hairballs or tangles in the brush roll.
This is a key split point: multiple reviews report clogs with medium/large debris, pet hair, or messy mixtures, sometimes without timely alerts. Others report strong day-to-day debris handling with reduced scattering, suggesting performance depends on debris type and home layout.
Comparisons are mixed; Dyson beats some rivals in speed or intelligence claims, but loses to others on cleaning or value.
In roundup-style coverage it’s presented as a top performer and award winner, but some side-by-side comparisons conclude the less expensive X8 (or other flagships) can be a better overall buy. The X9’s strengths are usually framed as best-in-class mopping and very strong all-around cleaning.
App experience is mixed: some call it intuitive or fluid, while others find it feature-light, patchy, or unintuitive.
App controls are generally seen as excellent, but physical controls and map-editing workflows get criticism in some reviews (sluggish button response or tedious confirmation steps). After setup, day-to-day control is usually straightforward.
Corner cleaning is generally helped by the side systems and shifting brush behavior.
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 call out a dirty-water sensing feature in the dock that can adjust washing based on how dirty the pads are. It’s consistently described as a higher-end automation feature rather than a must-have.
Docking and auto-empty reliability are mixed: some praise the dock design, others report missed emptying or docking struggles.
The OMNI dock is broadly viewed as full-featured and convenient, combining auto-empty, refill, and mop washing/drying. A minority of reports mention a one-off auto-empty clog/failure or debris dropping on the way back to the dock, so reliability is strong but not flawless.
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.
Reviewers cite exceptional performance on dried-on messes, including lab-style scoring that places it near the top of recorded results. Real-home testers also report it can scrub sticky spots that older robot mops often leave behind, though not always perfectly.
One reviewer explicitly says the robot is easy to set up and use.
When everything is dialed in, reviewers describe an almost set-and-forget experience with strong automation. Negative experiences typically stem from clogs, threshold issues, or mapping inaccuracies that demand more intervention.
Edge cleaning is mixed; some praise wall and skirting-board performance while others say edge pickup lags.
Edge cleaning is typically a strength thanks to extending brush/mop behavior, with several reviewers noting good wall-hugging and baseboard coverage. A common caveat is that the roller shape may miss a strip near certain appliances or toe-kicks.
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.
Lower water left behind and hot-air drying are commonly noted, which can help floors dry faster and reduce lingering dampness. Some owners still mention long deep-clean cycles that may include recharge breaks, but drying performance is generally praised.
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.
Several sources emphasize that the roller design can handle small wet spills by separating dirty water rather than dragging a damp pad across the floor. Demo-style testing (e.g., spilled milk) suggests it can clean quickly with minimal smearing compared with traditional pad mops.
Carpet hair pickup can be good, but it is not backed by as many reviews as other categories.
Carpet hair pickup is widely reported as strong, including high pet-hair percentages in testing and positive real-home pet results. Performance can drop if debris clogs the airflow path or during tricky threshold transitions.
Hair pickup on hard floors is strong in the reviews that tested it.
Anti-tangle performance is mixed: some reviewers saw little wrapping, while others had to clear hair or use scissors.
Many sources highlight anti-tangle brush features (ZeroTangle/active hair removal) with lab tests showing near-zero tangling. At least one reviewer still experienced significant hair wrapping during problem runs, so it’s excellent but not guaranteed.
Fine-dust results are mixed across reviews, ranging from excellent lab pickup to poor deep-dust tests.
Hard-floor dust pickup is consistently described as strong, with reviewers noting reliable capture of micro debris and fine dust. Some negative reviews still credit it for routine dust pickup even when larger-debris clogs occur.
Hard-floor large-debris pickup is usually strong, especially in real-home crumb and oat tests.
Large-debris handling is generally good, but multiple reviews note edge cases where larger particles, thresholds, or entering/exiting the dock can lead to drops. Very large debris can also contribute to clogs on some floors.
The green light and illumination feature is repeatedly mentioned as useful for spotting dirt ahead.
Heated mop washing and heated-air drying are frequently highlighted, with some reviews noting adjustable wash/dry behavior. This is repeatedly framed as a premium feature that improves hygiene and reduces damp odors.
Some reviewers see the dirt-detection approach and floor transitions as genuinely distinctive, while another says it still does not out-innovate the field.
Reviewers frequently call out the roller self-washing concept and BLAST airflow path as meaningful advances over older hybrids. It’s still in a competitive field (other brands have strong threshold handling or alternative mop designs), but the X9’s implementation is often viewed as one of the more complete packages.
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.
Internal LiDAR is positioned as a design win for getting into tighter spaces compared with tower designs. Measured height is still around the high-3-inch range, so ultra-low furniture may remain out of reach.
Maintenance is not fully hands-off; some reviewers call out manual cleanup or weekly checks.
Routine upkeep is generally reduced thanks to dock automation and app reminders, but several reviewers still recommend periodic tank cleaning and occasional brush/roller clearing. Sticky, paste-like messes can create a bigger cleanup burden.
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.
Some reviewers describe fast, efficient coverage and strong navigation once maps are set. Others report inaccurate initial mapping (especially in larger rooms) and more manual tweaking than expected for a flagship.
Mop lifting behavior exists, but not every reviewer finds it flexible enough in mixed-floor situations.
Multiple reviews mention automatic lifting behavior to protect carpets (mop lift, and in some descriptions additional component lifting). This generally helps with mixed-floor homes, though the robot is still limited on very tall thresholds or very thick rugs.
Mopping is above average overall, especially on fresh sticky messes, but some tests show misses or only partial stain removal.
The self-washing roller mop is repeatedly called the standout feature, delivering strong scrubbing and excellent day-to-day hard-floor cleaning. A few tests found minor limitations (toe-kicks/appliances it can’t slide under, or slight stickiness/residue on messy stress tests), but it still ranks among the best.
Cleaning runs can be quiet enough for normal activity, but dock drying and self-empty cycles are notably louder.
Operational noise is generally described positively (quiet or unobtrusive), and some coverage suggests BLAST aims to improve performance without a big noise penalty. Few reviews provide direct measurements, so perceptions dominate.
Obstacle avoidance is one of the more consistently praised robot traits.
Obstacle avoidance is generally rated above average, with good performance around common household items. Still, multiple reviewers report occasional real-world snags (chair legs, protrusions, or clutter), so it’s not consistently flawless.
Heated drying and roller cleaning are described as helping prevent smells.
Hot-air drying and regular mop washing are repeatedly credited with preventing the damp, mildew-like smell that some robot mops develop. A few owners still clean the dirty-water tank regularly to avoid odors.
Bagless operation is repeatedly cited as reducing ongoing costs compared with bagged rivals.
Ongoing costs can include disposable dust bags and detergent, and some reviews cite specific replacement pricing. This contributes to the sense that the X9’s total cost of ownership is premium, especially versus the X8.
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.
Pet-home suitability is supported by explicit pet-home framing and by cleanup results in homes with cats or dogs.
Pet-focused commentary is largely positive: tests show strong pet-hair pickup and many highlight pet-oriented app features. The main pet-related downside raised is that heavy hair and larger debris can still contribute to clogs in certain homes.
Value is mixed; some say the performance or pricing is justified, while others say rivals undercut it or the price feels high.
Value is polarized: some reviewers say the performance and automation justify the splurge, while others recommend it only on sale or prefer the cheaper X8/competitors at full MSRP. The $200+ gap to close siblings is a recurring theme.
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.
Self-cleaning is a clear feature advantage, but roller washing is not flawless in every test.
Both the robot and dock emphasize self-cleaning: the roller refreshes during runs, and the dock can wash and dry the mop and clean its basin. Reviewers still report occasional manual cleanup after unusually sticky or heavy messes.
The heated-water and solution system is useful, but several reviewers complain detergent is not included or note design compromises.
A detergent reservoir/auto-dispensing system and adjustable water output are noted across several reviews, enabling hands-off mopping. A few sources mention proprietary-solution recommendations or smaller solution tanks, which can increase refills or cost.
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.
Roller-based mopping is often praised for avoiding smear and residue.
Many reviews report low water left behind and good streak control, and some highlight adjustable moisture settings. However, a few stress tests (jelly or flour-and-water paste) left mild residue or streaks, indicating outcomes depend on mess type and settings.
Stuck resistance is strong in some homes, but one reviewer reports it getting trapped under low furniture.
Reports vary from near trouble-free operation to frequent help alerts depending on home layout. Thresholds and odd obstacles can cause wedging or debris drops in some tests, while careful mapping/no-go zones improves reliability for others.
Reviews mostly describe suction as strong, though one test-heavy review says it falls well short of older Dyson standards.
Most reviews describe very strong pickup driven by Ecovacs’ BLAST airflow approach, with top-tier results on both hard floors and carpet. A few reviewers say the real-world improvement over the X8 is modest and that large debris can still trigger drops or clogs.
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.
The internal LiDAR approach avoids a tall turret and helps it reach under more furniture than tower-based bots. Still, reviewers note the roller mop can’t slide under some low-clearance areas the way flat pads can.
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 clean/dirty tank setup is commonly described as easy to use, but there are tradeoffs: some miss transparent or externally visible tanks, some describe smaller/hidden tanks requiring more frequent refills, and dirty tanks can have corners that trap grime.
One hands-on video calls the robot heavy and cumbersome to lift.
