One review says Dyson does not include spare rollers, brushes, or other ancillaries in the box.
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 is frequently praised: the dock’s wood-look top and furniture-like footprint blend into living spaces better than many rivals. A minority dislike the faux-wood finish or find the dock less attractive in person.
AI and automation are central to the product and generally work, though real-world stain detection is not universally convincing.
App and automation are feature-rich: schedules, zones, room-specific routines, dirt-prioritization, and voice assistant support are widely praised. Common nitpicks include occasional connectivity hiccups, confusing menu choices, and missing real-time map progress in some experiences.
Blowback and scattering are usually controlled, with some reviewers noting it avoids flinging small particles. However, the side brush can flick larger debris around, and a few tests report scattered grains on hard floors.
Rugs and mixed floor transitions are a strong point in supportive reviews.
Rug handling is usually good, especially because the retracting mop prevents wet pads from dragging onto carpets. Still, the mop arm can occasionally catch on rug edges/corners, and very thick or tricky rugs may need keep-out or no-mop zoning.
Setup is a consistent strength across written and video reviews.
Setup is typically quick and well-guided through the app, with packaging and quick-start materials helping. Initial mapping can take multiple runs, and a few users report early hiccups aligning the robot on the dock or connecting to Wi-Fi.
The robot is described as responsive to obstructions, stopping or rerouting around people/pets and common objects. It’s not perfect in every edge case, but it tends to avoid creating bigger messes when something blocks its path.
Battery life is good enough for many homes, but some tests say it still trails top rivals.
Battery performance is generally strong for large-area runs, often finishing typical floors without intervention and returning to recharge as needed. Charging can feel slow for some users, but recharge-and-resume behavior is reliable in most accounts.
Multiple reviews highlight the bagless bin and dock design as a standout convenience.
The bagged dock system is praised for cleanliness and low-touch disposal, typically lasting weeks to around two months depending on shedding and home size. Internal bin is small but rarely needs manual emptying thanks to frequent auto-empty cycles.
Reviews that discuss build quality largely call the robot well-made or solid.
Build quality is generally described as solid with removable, serviceable parts. Some mention cosmetic scuffing during early mapping runs from gentle bumping, but no widespread structural issues are reported in these reviews.
High-pile carpet results are split sharply, with one review praising deeper-shag boost behavior and another measuring poor dense-carpet pickup.
High-pile/shag carpets are a weak spot for the vacuum-only model in one review, with quick tangling/stalling in long fibers. For homes with lots of high-pile, expectations should be tempered or zones configured to avoid problem rugs.
Low-pile carpet pickup looks middling in the dust-mat test that measured it.
Low-pile carpet pickup is generally very good, handling daily hair and debris well. Some users still notice occasional leftover strands on rugs and may choose extra passes for a more thorough finish.
No summary yet.
One lab review reports no noticeable hairballs or tangles in the brush roll.
Comparisons are mixed; Dyson beats some rivals in speed or intelligence claims, but loses to others on cleaning or value.
Comparisons usually place the j9+/Combo j9+ among the best for vacuuming and obstacle avoidance, with advantages over older Roombas. Several reviewers note that top hybrid competitors can outperform it in deep scrubbing or self-maintenance features.
App experience is mixed: some call it intuitive or fluid, while others find it feature-light, patchy, or unintuitive.
Controls are straightforward: the app handles most functions, with a simple on-robot button for start/pause and basic status lights. Some reviewers wish for richer in-app live tracking and clearer guidance in the manual/owner docs.
Corner cleaning is generally helped by the side systems and shifting brush behavior.
Corner cleaning is a known limitation: as a round robot with a single side brush, it can miss tight corners or smear debris in corner flour-style tests. Edges and open perimeters are better than sharp corners.
One test-focused review says groove and joint pickup on hard floors remains incomplete.
Crevice and groove pickup is repeatedly called out as improved versus older Roombas, aided by stronger suction and the dual rubber rollers. It performs well on seams and along transitions in testing.
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.
Docking and auto-empty reliability are mixed: some praise the dock design, others report missed emptying or docking struggles.
Auto-empty docking is consistently reliable, with the robot returning to empty and resume without much user intervention. Bagged disposal keeps the process clean, and many users report weeks of hands-free vacuuming before needing to swap the bag.
Dock-related cleaning and drying noise is a common complaint.
Dock emptying volume is inconsistent across reviewers: some describe it as very loud, while others find it comparatively quieter and less high-pitched than older Roombas. Either way, the empty cycle is brief and can be scheduled around quiet hours.
It can remove dried-on stains, but not always in one pass and not every reviewer was impressed.
For dried-on stains, SmartScrub/back-and-forth motions improve results and can remove many common spots like dried juice, litter prints, and tracked-in dirt. Very sticky food or heavy buildup may still require manual spot work or a pad change afterward.
One reviewer explicitly says the robot is easy to set up and use.
Day-to-day use is strongly praised once maps are set: scheduling, recharge-and-resume, hands-free emptying, and reliable obstacle avoidance reduce babysitting. Early learning runs can require a bit of attention, but it becomes largely set-and-forget.
Edge cleaning is mixed; some praise wall and skirting-board performance while others say edge pickup lags.
Edge cleaning is good for a round robot but not flawless: it follows baseboards well in open areas yet can leave debris along edges and misses some grime in tight perimeter spots, especially during mopping.
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.
App-based maintenance reminders for filters help keep performance consistent, with clear prompts on when to replace. Filters still require planned replenishment since they aren’t washable.
Filtration is a weak point in the teardown-style reviews, which question both performance and how clearly Dyson specifies it.
Dust containment is generally solid, helped by a sealed, bagged dock and replaceable filters. Filters are not washable and need periodic replacement, but most reviewers report clean handling with minimal dust mess.
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 is strong in many reports, though a few users still see stray hairs on low-pile rugs and may prefer an extra pass for perfection. Overall it’s above average for daily maintenance.
Hair pickup on hard floors is strong in the reviews that tested it.
Hard-floor hair pickup is a consistent strength, especially for pets and long human hair. A few mention the occasional hair clump, but overall results are strong with minimal leftover hairballs.
Anti-tangle performance is mixed: some reviewers saw little wrapping, while others had to clear hair or use scissors.
Dual rubber rollers reduce tangling compared with bristle rollers, and several reviewers report noticeably less hair wrap. Some periodic hair removal is still needed, especially in heavy-shedding homes.
Fine-dust results are mixed across reviews, ranging from excellent lab pickup to poor deep-dust tests.
Fine dust pickup on hard floors is consistently reported as excellent, including flour/sand-style tests in some reviews. Multiple passes can further improve results, especially on carpet fine-particle stress tests.
Hard-floor large-debris pickup is usually strong, especially in real-home crumb and oat tests.
Large debris pickup is strong overall, though a few note the side brush can flick bigger bits around before they’re captured. In most homes it handles cereal, kibble, and tracked-in debris well, with occasional stragglers in corners.
The green light and illumination feature is repeatedly mentioned as useful for spotting dirt ahead.
Some reviewers see the dirt-detection approach and floor transitions as genuinely distinctive, while another says it still does not out-innovate the field.
The combo design is seen as meaningfully innovative: the fully retracting mop arm reduces carpet-wetting risk, and the auto-fill dock adds true hands-free mopping convenience. It’s less novel on pad washing, where competitors often do more.
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.
The low-profile body helps it fit under more furniture than bulkier rivals, improving coverage in real homes. Dock size is still substantial, but the robot’s height is generally a plus.
Maintenance is not fully hands-off; some reviewers call out manual cleanup or weekly checks.
Maintenance is moderate: the bagged dock reduces daily hassle, but mop pads still require manual washing/swapping and parts like filters/brushes need periodic attention. Several reviewers call the pad-care step the main ongoing chore.
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.
Mapping and pathing are generally systematic and thorough, with efficient row cleaning once the home is learned. Initial mapping is sometimes slow or clumsy compared to LiDAR bots, and a few tests note slightly longer overall run times than some competitors.
Mop lifting behavior exists, but not every reviewer finds it flexible enough in mixed-floor situations.
The retracting mop mechanism is a defining strength, reliably keeping carpets dry by fully lifting/stowing the pad on top of the robot. It enables true vacuum-and-mop-in-one-run behavior without worrying about damp rugs.
Mopping is above average overall, especially on fresh sticky messes, but some tests show misses or only partial stain removal.
Mopping is generally effective for routine upkeep, with smart back-and-forth scrubbing helping on stains. It can struggle with sticky messes and heavy grime compared with spinning/vibrating pad competitors, and edges/corners remain challenging.
Cleaning runs can be quiet enough for normal activity, but dock drying and self-empty cycles are notably louder.
Noise is a mixed bag: in-room vacuuming is often described as noticeable but tolerable, while auto-emptying can be loud for some. A few reviewers found the empty cycle quieter than other robots, but others measured/mentioned it as disruptive.
Obstacle avoidance is one of the more consistently praised robot traits.
Obstacle avoidance is a defining strength: the camera-based system reliably dodges cords, toys, shoes, and pet waste in most tests, and often outperforms rival bots in clutter. It’s not flawless, but it dramatically reduces stuck events and accidental messes versus non-vision robots.
Heated drying and roller cleaning are described as helping prevent smells.
Bagless operation is repeatedly cited as reducing ongoing costs compared with bagged rivals.
Ongoing costs are a real factor: bags, filters, brushes, and occasional pads add recurring spend. The upside is the bagged system is clean and parts are widely available, but budget-minded buyers should plan for replenishment.
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 households benefit from strong poop/pet-waste avoidance, plus reliable hair pickup on hard floors and rugs. Multiple reviews highlight the pet waste guarantee as a key confidence booster in cluttered 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 polarizing: most agree performance and automation are premium, but the MSRP feels steep and many recommend waiting for sales. Those upgrading from older Roombas or prioritizing obstacle avoidance are more likely to feel it’s worth the spend.
Privacy gets limited but notable mention: Dyson says footage stays on-device, but the app still asks for permissions.
Privacy controls are a recurring discussion point because the robot uses a camera for navigation and obstacle recognition. Reviews note opt-in options and iRobot’s stated controls/encryption, but some users may still prefer a non-camera approach depending on comfort.
Runtime is usually described as solid to good, with enough coverage for many homes.
Runtime is generally strong for a premium robot, commonly around two hours in everyday use, with recharge-and-resume covering larger spaces. Expect longer total job times when both vacuuming and mopping, or when using max power/two-pass settings.
Self-cleaning is a clear feature advantage, but roller washing is not flawless in every test.
The heated-water and solution system is useful, but several reviewers complain detergent is not included or note design compromises.
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.
Residue and streaking are usually minor, but some reviewers notice occasional streaks or sticky patches after messy tests like jam/jelly. Regular pad washing and appropriate water/solution settings help reduce visible streaking.
Stuck resistance is strong in some homes, but one reviewer reports it getting trapped under low furniture.
Stuck events are infrequent once maps and keep-out zones are tuned, but the robot can still snag on bath mats, high-pile rugs, tight gaps, or situations where the mop arm can’t retract cleanly. Overall, it improves after the first few runs.
Reviews mostly describe suction as strong, though one test-heavy review says it falls well short of older Dyson standards.
Across reviews, suction is a standout: strong pickup on hard floors and carpet, with smart boost behavior and fewer repeat passes than older Roombas. A few testers still rate raw power a step behind the most aggressive premium competitors, but most call it top-tier for daily debris.
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.
Reliability feedback is mostly positive over weeks of use, but a few reviews mention glitches (unfinished jobs, mode misbehavior) and at least one report of a defective unit that required replacement. Keeping receipts for early runs is commonly advised.
Under-furniture reach is a clear weakness for homes with toe-kicks, low beds, or low cabinets.
Under-furniture reach is good thanks to the low profile and persistent navigation, with multiple reviewers noting it cleans under beds, desks, and tables. Very low clearances still depend on your furniture height.
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.
Auto-fill dock is a major convenience, with many citing weeks of mopping before refills in average use. A few find the reservoir awkward to handle/refill, but the concept and day-to-day automation score highly.
One hands-on video calls the robot heavy and cumbersome to lift.
