Compare Dyson V11 Outsize Cordless Vacuum Cleaner vs BLACK+DECKER Powerseries Extreme Cordless Vacuum Cleaner

Filtration is strongly praised across reviews, with sealed HEPA-style systems and dust containment repeatedly described as keeping fine particles inside the vacuum.

Filtration is the clearest weakness: multiple reviewers reported failed smoke tests, unsealed canisters, poor dust containment, or little filtration despite one light-use demo seeing debris trapped in the filter.

High-pile carpet results are mixed: suction helps deep cleaning, but some reviewers found thick carpet hard to push or problematic for large debris.

High-pile performance is poor in the lab review, with only 24% debris pickup reported.

Hard-floor seal evidence is very positive, with reviewers linking strong crevice pickup and hard-floor performance to an excellent cleaner-head seal.

Hard-floor seal evidence is negative, with one lab review calling the cleaner-head seal relatively weak and linking it to inconsistent results.

The Outsize is repeatedly framed as a heavy-duty cordless option for large homes, big messes, and near-upright cleaning demands.

Heavy-duty suitability is weak, with reviewers saying it is not right for heavy-duty cleaning and lacks power for larger messes.

The oversized bin is one of the strongest points: reviewers like the large capacity and fewer emptying stops, though it contributes to bulk.

Bin feedback is mostly negative, citing small capacity, tricky removal, weak sealing, and one reviewer calling the cup terrible.

Setup is usually described as easy or straightforward, although one reviewer was initially overwhelmed by the number of parts before sorting them.

Setup evidence is limited and mixed, with one reviewer struggling for a week before figuring out the battery insertion.

Ownership-cost comments are favorable where mentioned because washable filters and reusable parts keep routine maintenance costs low.

Ownership-cost evidence is limited and slightly negative because replacement filters were described as costlier than a compared Kenmore option.

Emptying is mostly praised as easy and hygienic, but some reviewers note stuck debris or the large bin making handling less tidy.

Emptying and mess control are mixed-negative, with repeated complaints about tricky removal, flying dust, dropped debris, or awkward emptying despite a few easy-empty mentions.

Storage feedback is mixed: wall docks and organized charging help, but reviewers dislike that it cannot stand alone or that docks may not hold every attachment.

Storage is a major strength because reviewers repeatedly praised the self-standing design, compact storage, and upright convenience, though one noted it can be tippy.

Hair pickup on hard floors is strongly positive where tested, with reviewers describing fur, food crumbs, and dust being removed easily.

Hard-floor hair pickup is mixed, with one reviewer praising dust and hair pickup while another said the Extreme struggled on wood laminate hair.

Small-space suitability is a recurring weakness because reviewers say the Outsize is overkill for apartments and harder to fit into narrow areas.

Small-space suitability is strong, with several reviewers calling it good for small apartments, quick tasks, and tight areas.

Stair evidence is limited but positive in a pet-owner review that praised fast, deep cleaning on bedrooms and stairs.

Stair feedback is mixed: some reviewers found it usable or better with the detachable configuration, while others said it was less maneuverable or lacked a small powered stair setup.

Large-debris hard-floor intake is generally strong but not flawless, with some reviewers noting scatter, pushing, or worse results in difficult tests.

Large hard-floor debris handling is inconsistent and often weak, with several reviews describing snowplowing, pushing, breakage concerns, or kickback despite a few positive quick tests.

Runtime is one of the strongest consensus positives, especially when two batteries effectively double cleaning time for large homes.

Runtime is context-dependent: low-power or swappable-battery use can be adequate, but high-power runtime and charging speed drew limitations.

Reviewers repeatedly praise the Outsize for class-leading cordless suction, upright-like airflow, and strong pickup, with only rug drag and weight-related control as side effects.

Evidence is split: several reviewers measured or praised strong airflow and pickup, while controlled testing also found weak suction or below-average suction versus stronger cordless models.

Weight is the most consistent drawback: reviewers repeatedly call the Outsize heavy, arm-tiring, or awkward compared with smaller stick vacuums.

Weight is mostly positive for handheld and general use, though some reviewers found the Extreme heavier or above-floor use more tiring.

Comparative comments are positive for performance, with reviewers placing the Outsize ahead of many cordless competitors and even near full-size uprights in some tests.

Comparative performance is mixed: it beats some budget rivals in build and airflow and matched one Dyson carpet test, but other budget models were said to perform better overall.

Handheld conversion is useful for furniture, cars, and patio areas, but several reviewers find the large bin and heavy body awkward in handheld use.

The handheld conversion is useful for upholstery and handheld tasks, with one reviewer specifically saying it passed the handheld test.

Tangle resistance is generally good thanks to Dyson brush design and detangling tools, though very long hair can still wrap.

Hair-wrap resistance is highly mixed: some reviewers found it anti-tangle or jam-free, while others reported poor tangle resistance or hopeless wrap.

The tool set is widely praised for versatility, upholstery, crevices, pet hair, and hard-to-reach jobs, though one reviewer disliked the lack of an accessory carrying bag.

Accessory coverage is mixed: some reviews liked the pet and crevice tools or extra attachments, while others criticized the limited attachment set.

Handling is split: the Outsize can swivel, glide, and cover area well, but its size, weight, and large head reduce agility in tight spaces.

Maneuverability is consistently strong, with reviewers praising easy steering, nimble handling, low weight, and under-furniture movement.

Low-pile carpet pickup is consistently strong, with multiple tests describing flawless or near-flawless performance.

Low-pile or general carpet pickup is generally good for smaller debris and surface pickup, but not consistently deep or premium.

Clogging evidence is positive but limited, with one review noting that extra-large debris did not get stuck in the intake.

Clogging evidence is split: one review warned the brush can jam on cords or tassels, while another praised no clogs or stuttering in debris tests.

Edge and baseboard cleaning evidence is positive but limited, with one reviewer surprised by how well the Outsize handled baseboard debris.

Edge cleaning is mixed: one reviewer found it left debris along walls, while another praised the crevice tool for baseboards and tight corners.

Hair-removal channel evidence is limited and mixed, with one reviewer seeing significant long-hair tangling after a measured hair test.

Hair-removal channel evidence is negative, with a lab review saying long hair had to be manually cut away and removed.

Kid-friendliness evidence is limited but positive, with one household saying easy access even got the kids using it.

Kid-friendliness received one strong positive test, with a reviewer saying it passed a kid-use test.

Hair pickup on carpets is a standout strength in pet-heavy homes, with reviewers describing deeply embedded pet hair being pulled from carpets.

Carpet hair pickup is positive, with reviewers reporting above-average or pretty good hair pickup on carpet.

Crevice and groove pickup is positive in lab and pet-owner use, though the large handheld body can make tight vehicle crevices harder.

Crevice and groove pickup has one strong positive mention for reaching tight edges and corners.

Onboard storage is mixed: wand clips and mounted tools help, but some reviewers complain about missing bags or docks that do not hold every accessory.

Onboard tool storage has one positive mention for the crevice tool mounting to the base and being ready quickly.

Overall sentiment is strongly favorable for large-home use, with reviewers praising performance heavily while repeatedly warning about weight and price.

Overall opinion is mixed-positive: most reviewers recommended it for budget or quick cleaning, while one lab-style review could not fully recommend it beyond tight-budget use.

Cordless convenience is a major strength, with reviewers emphasizing easier room-to-room cleaning, no outlet hunting, and faster everyday use.

Cordless convenience received a positive use-case mention for house and car cleaning.

Tool changes are generally praised as quick and simple, with reviewers calling out quick-release buttons, easy accessory swaps, and improved brushroll access.

Tool changes are mostly easy, especially the crevice tool, though one reviewer found the main dustbin/body connection less smooth than the accessory.

The LCD and controls are frequently praised for runtime countdowns, mode changes, and maintenance prompts, though the trigger is a recurring ergonomic complaint.

Controls are generally positive for simple speed selection and power modes, with the main caveat that there is no digital display.

Value opinions are mixed: many reviewers think the performance justifies the price for large homes, while others flag it as very expensive or not the best V11 value.

Value is one of the strongest themes: reviewers repeatedly framed it as affordable, budget-friendly, or very good for the price, though value depends on accepting compromises.

Above-floor and upholstery cleaning is useful with the right tools, especially for hair, but handheld weight limits comfort for longer or cramped jobs.

Above-floor pickup is mixed: handheld and crevice use were praised, but one review found base suction below average for handheld tasks.

Durability expectations are positive where mentioned, with reviewers describing the Outsize as a top-line product with quality and longevity.

Durability impressions are cautiously positive, with reviewers describing sturdy pieces, solid construction, and no failure after extended test abuse.

Area-rug handling is mixed: auto suction helps transitions, but very high suction can cling to rugs and make cleaning feel like a workout.

Area rug handling is mixed, ranging from a good rug crumb test to sticking or difficult pushing on certain rugs.

Headlight or illumination feedback is positive where the Laser Slim Fluffy head is included, making tiny dust easier to see.

LED/headlight feedback is strongly positive, with reviewers repeatedly calling the lights bright, helpful, liked, or a favorite feature.

Pet owners report very strong hair pickup across carpets, hard floors, furniture, and pet-heavy homes, making pet cleanup one of the product’s clearest strengths.

Pet evidence is mixed but generally favorable for hair pickup, with praise for pet hair handling and a strong caveat that filtration/sealing can matter for pet households.

Versatility is praised in reviews that highlight broad attachment use, hard-to-reach cleaning, and switching among floors, furniture, and car tasks.

Versatility received a positive multi-surface mention across hard floors, carpet, upholstery, and clothing lint.

Build quality evidence is limited but positive, with one reviewer calling it a top-of-the-line product expected to last years.

Build quality is better than some budget rivals but still budget-grade, with praise for sturdiness alongside caveats about cheaper plastic.

Medium-pile carpet performance is strongly positive, including deep-clean testing and broader V11 evidence of excellent carpet cleaning.

Medium-pile and general carpet test evidence is strong, with multiple reviewers reporting very good pickup or above-average deep-clean performance.

Smart suction and automation are consistently praised, especially auto mode that adjusts power by floor type to balance cleaning and runtime.

Smart/automation evidence is positive where AutoSense is tested, with reviewers saying it adapted to surfaces and offered higher-end-style floor detection at a budget price.

Battery feedback is highly positive overall, especially for swappable batteries, dual-battery setups, and the ability to keep cleaning without long interruptions.

Battery and charging are a strength because reviewers liked the removable/swappable Black+Decker battery system, even when charging speed or high-power runtime drew caveats.

Under-furniture pickup is a strength because the stick design and top-mounted bin let it lie low and reach under beds, couches, and tables.

Under-furniture pickup is consistently positive thanks to low-profile movement and the ability to reach under beds, furniture, and tables.

Airflow blowback evidence is limited and negative, with one reviewer bothered by warm vented air hitting their face or hands in close work.

Airflow blowback is a real hard-floor caveat, with one lab test reporting rice blown away and another quick test noticing some kickback.

Debris illumination is highly praised in the Outsize Plus evidence, where the green laser made hidden hard-floor dust visible.

Debris illumination is a standout strength, with reviewers saying the lights revealed missed dust and lit the cleaning path well.

Design comments are positive overall, describing the vacuum as sleek, slim, smart-looking, and not bulky despite its large cleaning hardware.

One reviewer liked the modern-looking colors and design.

Low-profile cleaning is praised because the cleaner head and stick layout can reach under low furniture and narrow spots.

Low-profile design is strong, with reviewers noting it can lie or go completely flat under furniture.

Fine-dust pickup on hard floors is usually strong, especially with laser/fluffy-style heads, though one hard-floor stress test found average results.

Fine hard-floor pickup is mostly positive in tests involving sand, fine debris, or light hard-floor cleaning.

Ease of use is mostly strong thanks to cordless convenience, auto mode, simple setup, and easy tool use, but trigger effort and weight pull scores down.

Ease of use is a strength overall, with reviewers calling it easy to operate, smooth to use, and convenient.

Innovation evidence is positive, with reviewers pointing to major cordless advances and Dyson designs that competitors copied.

Innovation is positive for the price, especially self-standing storage and AutoSense-style features that reviewers considered rare or absent on more expensive vacuums.

Maintenance is generally considered easy, supported by washable filters, alerts, easy brushroll access, and simple cleaning steps, though occasional hair removal remains.

Maintenance is generally positive because filters are washable and easy to rinse, though hair and dustbin mess still require attention.

Noise feedback is mixed: some reviewers find it quieter than expected or comfortable in lower modes, while others complain that higher settings are loud.

Noise impressions vary from manageable to louder than average, with one review calling it quieter at lower settings and others noting elevated noise.

The wider floorhead is praised for coverage and speed in large areas, though some reviewers note it sacrifices agility in tight spaces.

Floorhead design is mostly praised for carpet performance and agitation, though the broader evidence shows it can create hard-floor tradeoffs.

Stuck-resistance evidence is negative and limited, with extreme suction on rugs described as making the vacuum difficult to move.

Stuck resistance has a negative rug-related finding, with the low head sticking to certain rugs or becoming hard to push.

Cyclone evidence is limited but positive, with the Outsize’s cyclone system tied to powerful, fade-free suction.

Hose feedback is limited and negative, with one reviewer finding the extension hose less useful because it added handling faff.

Packaging received one positive mention, with the retail box and packaging described favorably.

Support evidence is limited and negative, with one reviewer reporting that Dyson support directed them to Amazon rather than solving the issue.

Surface-safety evidence is limited but positive, with one reviewer saying the hair tool gripped upholstery gently while removing hair.
