Compare Shark PowerDetect NeverTouch Robot Vacuum & Mop vs Roomba Combo j9+ Robot Vacuum & Mop

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.

The app covers basics like scheduling, room selection, and no-go zones, but multiple reviews call it laggy or less feature-rich than leading competitors.

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.

Area rug handling benefits from mop lift/drop behavior to keep rugs drier, but a few reviewers mention imperfect carpet detection in mixed-floor homes.

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 usually described as straightforward, with guided app steps; mapping can take a bit of time but is not typically a blocker.

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.

In at least one detailed test, runtime and efficiency were below average for a flagship-priced robot, especially when compared to top competitors.

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.

It uses a bagless system with an auto-empty base, which reduces frequent emptying, but the onboard bin is small and some owners still report occasional manual emptying.

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.

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 more variable, with some tests noting leftover loose debris on longer fibers compared to its hard-floor performance.

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 is usually strong for day-to-day debris, though some reviewers mention it occasionally needs a second pass to finish the job.

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.

Medium-pile carpet pickup is generally strong on surface debris, but deep-cleaning performance varies and some reviews mention needing extra passes.

No summary yet.

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.

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 improves with edge air-blasts and pad reach, yet multiple reviews still recommend a quick manual touch-up for tight corners.

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.

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.

Docking and hands-free automation are major strengths, yet a minority of reviews cite reliability issues with auto-empty strength or the thoroughness of pad drying.

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 noise is mostly tied to the pad drying fan or hum, which can be loud for some and may run for an extended time.

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.

Dried-on mess performance is better than typical robot mop combos in several tests, though it is not a full replacement for manual scrubbing on heavy grime.

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.

Day-to-day use is generally easy once set up, but app lag and the occasional navigation quirk can add friction.

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 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.

Edge following is generally decent and helped by edge-focused features, but several reviewers note it keeps a small buffer from baseboards rather than hugging edges tightly.

The auto-empty system improves mess control overall, but reliability isn’t perfect—some reviewers report partial emptying or inconsistent suction at the base.

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.

HEPA filtration and good dust containment are commonly highlighted, with several sources positioning it as a solid option for allergy-conscious homes.

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.

Floor drying is often described as quick after mopping, yet some tests say it can leave floors wetter than preferred and the dock drying cycle can run for hours.

Carpet hair pickup scores well in some tests, but other reviewers report occasional pet-hair clumps or missed strands on carpet.

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 generally good, though long-hair performance can vary depending on maintenance and brush condition.

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.

Tangle resistance is mixed: some reviewers say the brush resists wrap well, while others experienced long-hair tangles that required manual cleanup.

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 pickup on hard floors is generally good, but a few tests report it can push around small grains or struggle with very fine powder without extra passes.

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.

Large debris intake on hard floors is consistently praised, with strong results on tracked-in dirt and common snack-size debris.

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 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.

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.

The dock reduces day-to-day maintenance, but owners still need periodic tray cleaning, sensor wipe-downs, and hair removal—especially in pet or long-hair homes.

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.

Navigation and path efficiency vary widely by reviewer: some praise fast, organized coverage, while others describe slower runs, random patterns, or occasional hesitation.

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.

The mop lifting and pad-drop approach is a key benefit for mixed flooring, though some reviewers note lag or that it is less refined than the best-in-class systems.

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 one of the strongest aspects in many reviews, with good agitation and stain handling, though it can run a bit wet and won’t replace deep manual scrubbing.

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.

Noise feedback is mixed: some reviewers found the robot quiet enough to run during calls, while others said the vacuum or the mop-pad drying cycle is noticeably loud.

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 ranges from average to excellent: it often avoids larger items, but some reports include cord run-overs or hesitation around unrecognized obstacles.

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.

The odor-neutralizing cartridge is mentioned as a useful quality-of-life feature, especially in pet homes, though its impact is subjective.

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.

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 polarizing: some reviewers call it compelling for the self-washing dock and mopping results, while others feel the price is hard to justify given app and carpet tradeoffs.

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 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 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.

The self-cleaning dock is a standout: it can wash pads automatically, but drying can be noisy and some reviewers wish it were hotter or more thorough.

Liquid/solution guidance is inconsistent across reviews: some describe using water or a mix, while others report unclear instructions or avoid cleaning solution altogether.

Many reviews report minimal streaking and better-than-average wipe-and-lift behavior, but a few saw smearing when the pad was very wet or the pass was shallow.

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 often a strength thanks to threshold handling and lift behavior, but there are scattered reports of hesitations on low furniture or tricky transitions.

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.

Across reviews, suction is generally above average and strong enough for everyday debris, though a few tests note weaker results on very fine powder or certain carpets.

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.

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 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.

The large, self-refilling water setup supports longer mopping sessions and is repeatedly cited as a practical advantage over smaller hybrid systems.

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.
