Compare BLACK+DECKER Powerseries Extreme Cordless Vacuum Cleaner vs Dyson V8 Absolute Cordless Stick Vacuum Cleaner

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

High-pile carpet results were also excellent in the Modern Castle testing evidence.

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.

Filtration earned positive comments for sealed HEPA-style containment and cleaner exhaust that helps keep dust and allergens out of the air.

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

Reviewers found it capable of full-home or heavy-duty cleaning for many households, despite being cordless.

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

Debris illumination was a weakness because reviewers noted the lack of headlights or similar visibility features.

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

Setup was described as extremely easy, with little or no real assembly process required.

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

Headlight feedback was negative because reviewers flagged the lack of headlights as a missing modern feature.

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.

Smart-feature feedback was negative because the V8 lacks the modern smart features some buyers may expect.

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.

Emptying was consistently praised as easy, hygienic, and low-mess compared with older designs.

Stair cleaning was praised, especially when using the mini motorized or hair screw tools in handheld mode.

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

The bin received mixed feedback: reviewers liked stronger performance and reduced emptying frequency, but several noted the bin is small.

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.

Storage feedback was mixed because the dock and compact body help, but plug placement and separate accessory storage were recurring annoyances.

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

Runtime was usually considered enough for full-house or routine cleaning, despite max-mode limits.

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

Hard-floor hair pickup was praised by reviewers dealing with dust, human hair, and dog hair.

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

Noise feedback was favorable overall, with reviewers saying the V8 is quieter than newer Dysons, older predecessors, or loud uprights.

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

Hair-removal channel feedback was mixed to negative due to hair wrapping or needing to pull lingering hair from the bin.

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

Onboard tool storage was weak because extra heads and tools had nowhere convenient to sit on the vacuum.

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

The included tools were consistently valued as useful, versatile, and worth having, especially in the Absolute package.

Tangle resistance was generally good, but not perfect, with minimal tangles in tests and occasional hair wrap in personal use.

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

Ongoing ownership costs looked favorable where mentioned, with low maintenance needs cited as a strength.

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

Above-floor and upholstery performance was praised for dust, upholstery, cars, stairs, and difficult ground-in debris.

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.

Reviewers repeatedly described suction as strong, powerful, and consistent across floors, with enough airflow for routine cleaning and carpet work.

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

Low-pile carpet results were excellent in the Modern Castle testing evidence.

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

Cordless convenience was one of the most praised benefits, especially freedom from plugs, cords, and heavy machines.

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

Overall opinion was very positive across reviews, though not without price, bin, and feature caveats.

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.

Comparative performance was favorable against older models in some areas, though newer models still offer more advanced features.

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.

Value was strongly context-dependent: reviewers praised sale pricing and lower entry cost, but still called the vacuum expensive.

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

Tool changes were praised as quick, robust, and effortless, making the attachment system a clear usability strength.

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

Airflow blowback was a mild drawback in max mode because one review noted more air firing out the back.

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

Area rug handling was mixed because suction lifted hair well but could stick to rugs unless power was lowered.

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.

Clogging feedback was positive in the detailed test review, which found no clogging issues even with larger carpet debris.

Floorhead feedback was mixed: the older fluffy roller was called chunky, but the soft roller itself was praised for hard floors.

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

Build quality was viewed favorably, with reviewers describing the V8 and its attachment system as solid and robust.

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

Kid-friendliness was indirectly positive because one reviewer said kids used it thanks to its easy handling.

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

Stuck resistance was weaker on rugs when suction was too high, requiring users to lower power.

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

The handheld conversion was a major benefit, expanding the V8 from floors to cars, furniture, stairs, and above-floor cleaning.

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

Controls were mixed: battery or power indicators helped, but the trigger and grip drew comfort and sensitivity complaints.
