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

Accessory coverage varies by package and compared sources: some cite only a couple of tools (e.g., crevice and pet brush), while others reference broader attachment sets on certain versions; overall, tool selection is considered modest versus premium brands.

Most reviews describe a strong accessory set, often including a mini motorized tool and multiple nozzles for detail work. Bundle contents vary, and some reviewers note limited storage for all tools or the lack of a carrying case.

Multiple reviews mention a spray/kickback or blowback effect on hard floors, where debris can be pushed away rather than fully captured, especially with larger particles.

Assembly/setup is usually straightforward, but a few user experiences mention learning curve/friction points (notably battery insertion/fit and initial handling).

Battery convenience is a major theme: removable pack on the Extreme model enables swapping across the Black+Decker ecosystem and extending runtime with spares. Runtime claims are high on low power, while real-world high/strong settings are notably shorter; charging is often described as slow.

The click-in, removable battery is a consistent plus, making it easy to swap packs mid-clean. Many reviews describe bundles with two batteries (and sometimes a second charger) for extended sessions, while a few note that some trims/regions include only one battery and add-on packs are costly.

Bin size is described as on the smaller side in some reviews, and the bin/canister assembly can be finicky or feel flimsy depending on the model variant referenced.

The oversized bin is repeatedly praised for reducing how often you have to empty, making it better suited to large homes. The downside noted in multiple reviews is added bulk and a top-heavy feel compared with slimmer stick vacuums.

Build is generally described as solid for the price and able to take normal household use, though some note cheap-feeling plastics or a less-premium bin/parts compared with higher-end cordless models.

High-pile/shag performance is more mixed and can drop significantly, with some reports of weak embedded pickup and snowplow behavior as the head sinks into plush carpet.

High-pile carpet performance is strong, but the Outsize can feel overpowered. Reviews mention it may be difficult to push on thick rugs and can push around larger debris unless you open the intake gates or lower power.

Low-pile carpet pickup is generally rated as good for the price in several reviews, with strong surface pickup; independent lab-style scoring in one source is notably lower, suggesting variability by test method and debris type.

Low-pile carpet tests are consistently excellent, with reviewers reporting near-complete pickup in a single pass. Auto mode and strong agitation help it pull embedded grit without needing repeated passes.

Medium-pile carpet performance is frequently cited as a strength, including deep-cleaning-style tests where embedded sand pickup is described as higher than expected for a budget cordless.

On medium-pile carpet, testers report deep-clean results that match or beat other flagship cordless vacuums. It is frequently described as a standout for pulling sand and dust out of carpet fibers.

Reviews credit the larger intake and adjustable gates with helping prevent big-debris jams. Clogs are still possible if maintenance is ignored or if long hair builds up, but outright intake blockages are not a frequent complaint.

Controls are generally simple (multiple power levels and, in some variants, brush-roll control). Some versions also reference auto/adjusting suction behavior, but the core experience is basic and easy to learn.

The LCD and auto-adjusting behavior get frequent praise for showing remaining runtime and adapting power to different floors. The most common control complaint is the hold-to-run trigger/button style, which can fatigue your hand; one review also questions battery indicator accuracy.

The vacuum converts to a handheld unit for cars, stairs, and spot cleaning, which reviewers appreciate. The tradeoff is that the Outsize body is bulky and heavier than typical handhelds, so tight detailing and long sessions can be tiring.

Cordless convenience is a major win in daily use, with reviewers describing quick grab-and-go cleanups and easier room-to-room transitions. The benefits are strongest in larger homes where avoiding cord changes saves time.

Crevices and grooves are a strength: multiple reviews report strong pickup from floor seams and tight cracks. The included crevice tool is also described as effective for car detailing and hard-to-reach edges.

The multi-cyclone system is credited with maintaining strong, fade-free suction as the bin fills. Reviewers reference Dyson’s high-speed motor and cyclone design as key reasons it keeps pulling fine dust without feeling bogged down.

For floor cleaning, reviewers generally like the swivel and the ability to recline for under-furniture reach. Handling becomes more work in tight spaces due to the wider head and heavier body, and strong suction on thick carpet can make pushing feel strenuous.

Edge and baseboard cleaning is generally rated as good, with reviewers noting it can pull debris along walls without leaving an obvious line behind. Corner performance depends on head angle and the room layout, but results are usually above average for a stick vacuum.

Emptying is commonly described as workable but sometimes messy: users report dust flying or having to wrestle the bin off, with fine debris dropping during removal/emptying.

The slide/point-and-shoot emptying mechanism is widely described as hygienic and easy to use. A few reviews mention that hair or debris can occasionally stick inside the bin or at the door, requiring a quick manual clear-out.

Filtration and dust containment are a repeated weakness. Several sources note an unsealed canister and poor fine-particle control (including smoke/particle-test style failures), making it a poor choice for allergy-sensitive use.

Filtration is repeatedly framed as a strength, with reviewers describing a sealed system and HEPA-grade capture of fine particles. This makes it a frequent recommendation for allergy-conscious households, with few complaints about dust leakage during normal use.

The High Torque XL head is wider than standard V11 heads and helps cover large rooms faster. Multiple reviews like the adjustable intake gates and strong agitation, but the wider head is less nimble in tight areas; some bundles also include a dedicated hard-floor head while others do not.

No summary yet.

Hard-floor sealing is generally praised, especially in crevice-style pickup tests. A few reviewers note that debris scatter can happen with the wrong head or settings, so using the proper hard-floor head (when included) or adjusting the intake can improve results.

For carpets, reviewers describe strong pet-hair removal, including faster pickup in testing. High suction and motorized tools help lift hair from fibers, though longer hair can still require occasional brushroll cleanup.

No summary yet.

On hard floors, pet hair pickup is also described as very strong, helped by high suction and the wide cleaning path. Some reviewers mention that very light debris can scatter if settings are too high, but overall hair pickup remains a highlight.

Hair-wrap performance is inconsistent: some tests call it among the worst for tangling at its price, while others find it surprisingly acceptable with only moderate buildup. Expect periodic brush-roll cleaning.

Tangle resistance is better than many competitors, and some versions/tools are designed specifically to de-tangle hair. Still, long human hair can wrap around the brushroll in real use, so periodic manual removal can be needed.

Hard-floor fine debris pickup is described as decent in some reviews, but performance is inconsistent and often requires extra passes, particularly near edges or when debris distribution is uneven.

Fine dust pickup on hard floors is rated very highly in performance testing. Reviewers still point out that head choice matters; a soft roller style head (when included in a bundle) can be better for polishing hard-floor results.

Hard-floor large debris intake is a recurring complaint: multiple sources report it tends to push medium-to-large debris (rice/cereal/kibble) rather than reliably ingesting it.

The larger intake and adjustable gates help it swallow bigger crumbs and debris than many stick vacs. However, some tests and user impressions mention occasional scatter or debris push on certain surfaces, especially when using high power on carpet.

LED lighting is repeatedly called out as useful (often a standout feature at this price), improving visibility of dust and hair in darker areas and along edges.

Maintenance is recurring: washable filters are common, brush-roll hair removal is sometimes necessary, and several reviewers stress that neglected filters can cause performance issues.

Routine upkeep is straightforward: washable filters and occasional brushroll cleaning are the norm, and the display can prompt maintenance steps. Some reviewers still note that heavy hair loads or certain debris can require extra manual cleaning over time.

Maneuverability is a recurring strength, including easy navigation around furniture, low-profile reach under beds, and smooth handling for quick passes in typical rooms.

Noise is often described as a bit loud for its class in certain tests, though not universally framed as a deal-breaker given the price tier.

Noise is described as reasonable in Eco/Auto but noticeably loud in Boost/Max. Some reviewers find it quieter than expected for the suction level, while others still consider the highest setting too loud for close-quarters use.

Ongoing costs are generally low (washable filters), but replacement filters/batteries are discussed as practical considerations; the ability to share batteries across tools can reduce effective ownership cost for existing Black+Decker owners.

No summary yet.

Marketed and frequently discussed as pet-friendly, with generally solid pet-hair pickup on carpets and helpful tools on some bundles, but limited by filtration and variable anti-tangle behavior.

Pet owners benefit from the Outsize’s strong suction and motorized tools, with multiple reviews calling out excellent fur pickup and helpful pet-focused attachments. Exact tool availability varies by bundle, so pet-specific accessories may depend on the version you buy.

Consistently positioned as a budget standout: reviewers repeatedly frame it as hard to beat for the price, with strong carpet results and convenience features typically missing at this tier (self-standing, LEDs, swappable battery).

Price is firmly premium, and reviewers often call it expensive even when they like the performance. Value improves for large homes and pet owners who will use the bigger bin and longer runtime; for small spaces, several reviews suggest it is more vacuum than necessary.

Default/low-power runtime is frequently described as long for the price (often cited up to ~55 minutes), but practical runtime drops in higher modes and during real cleaning sessions. Boost/high-power runtime is commonly characterized as short (often around the teens of minutes in max-style use) and not sufficient for whole-home deep cleaning without a spare battery.

In Eco/Auto-style use, reviewers commonly report runtimes ranging from roughly 40 minutes to well over an hour per battery depending on head and surface. With two batteries, several sources describe reaching about two hours of total cleaning time. Boost/Max mode is treated as a short-burst option: many reviews cite roughly 8 to 12 minutes per battery. It is effective for deep cleaning, but reviewers agree it drains quickly compared with Auto or Eco.

Stair cleaning capability depends on variant and attachments: some comparisons note limitations in converting for stairs/handheld floorhead use, while others highlight convertible handheld utility with the right tools.

Storage is repeatedly praised due to the vacuum being able to stand upright on its own, with some models also including wall-mount storage/charging options.

The Outsize typically relies on a wall dock or stand and is often noted as not free-standing. Its larger size can feel bulky when stored, and some docks do not hold every attachment at once.

Airflow is often measured or described as strong for the price, while suction is more mixed: some reviews cite competitive wand suction, but others characterize overall suction as low for deeper or handheld-focused work.

Across the reviews, Outsize is described as one of the strongest cordless vacuums available, delivering near-upright cleaning power. Several testers call it the top performer for raw suction, but that strength can make plush carpet harder to push and can shove larger debris unless you adjust power or airflow.

Only a small portion of the review set discusses support directly, but that mention is negative, describing a slow, chat-heavy experience that ended without resolution. With limited data, reliability and service impressions are mixed and under-documented compared with performance.

Tool swaps are commonly described as quick and intuitive thanks to Dyson’s quick-release design. This makes it easy to move from floor cleaning to above-floor tasks without breaking momentum.

Under-furniture access is highlighted as good thanks to a low-profile head and the ability to get under beds and furniture more easily than many budget sticks.

Under-furniture reach is a consistent strength, with multiple reviews noting it can recline and clean under couches and beds without moving heavy furniture. The wide head helps cover open areas quickly once you have clearance.

Above-floor and handheld use is described as useful for quick jobs, but suction-at-base and handle-weight comments suggest it is less ideal for extended handheld cleaning versus dedicated handheld-focused designs.

Above-floor and upholstery results are strong with the mini motorized and hair-focused tools, especially on couches and pet beds. Several reviewers still caution that the weight and trigger-style control make long overhead sessions less comfortable.

Weight is generally characterized as lightweight to moderate for a cordless stick, though some mention a heavier-in-hand feel for above-floor tasks depending on configuration and variant.

Weight is the most consistent complaint: reviewers repeatedly call the Outsize heavy, especially for handheld, stairs, and overhead work. The extra bin size and larger head contribute to arm fatigue during long cleans.
