Compare BLACK+DECKER Powerseries Extreme Cordless Vacuum Cleaner vs Shark Stratos Cordless Vacuum IZ862H

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.

Included tools usually cover basics like a crevice/duster tool and an anti-allergen brush. Several reviewers wish it bundled more (powered upholstery tool, extra filters, or a dedicated pet tool depending on region).

Clean Sense IQ dirt sensing that automatically adjusts suction is generally viewed as useful, though at least one reviewer felt the boost was subtle aside from added noise.

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.

Area rugs are usually handled well, but thin or lightweight rugs can get pulled toward the head unless suction is reduced.

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

Assembly is typically fast and intuitive, with most reviewers set up in minutes; occasional fiddly steps are tied to the scent cartridge and its dial.

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.

Charging times are typically around 3 to 4.5 hours, and the removable battery is a plus. Some reviewers report performance is more consistent when the battery is kept fully charged or when a second battery is available.

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.

Bin size feels acceptable for many whole-home cleans, but some reviewers find it small or awkwardly shaped, especially when dealing with fine powders that cling to the interior.

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.

Durability impressions are positive in hands-on use, with reports of the body surviving bumps and feeling well built, although the overall unit is heavy.

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.

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.

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.

Carpet cleaning is often rated very good to excellent, including deep-clean style tests. One lab-style review found only average per-pass pickup versus top competitors, so expectations should be calibrated to mode and carpet type.

In comparisons, it is often positioned as competitive with top cordless models and has won category awards in some sources; a few reviewers still say other models may offer better value depending on sales and feature priorities.

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.

Controls and the LED display are widely liked, with clear mode changes plus battery and sensor feedback that are easy to read while cleaning.

Detaching to a handheld configuration is useful for stairs, furniture, and cars, but several reviewers note it can feel a bit heavy in the hand for extended above-floor work.

Cordless operation is repeatedly praised for quick daily cleanups and easier movement around furniture and stairs; the main limiter is how quickly runtime drops in higher modes.

Crevice and groove cleaning is strong in multiple tests, supported by good head sealing and effective crevice tools.

Steering and handling are commonly described as smooth and responsive with good swivel, though the head can feel bulky in tight gaps.

Ease of use is broadly praised for intuitive controls and smooth cleaning on mixed floors, with the main caveat being fatigue from the unit's weight during longer sessions.

Edge and baseboard performance is repeatedly described as very good, helped by strong sealing at the floorhead.

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.

Emptying is typically one-button and low-mess, but fine powders can stick inside the bin and require rinsing for a truly clean cup.

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.

Multiple reviews emphasize a sealed, HEPA-style filtration system and strong dust containment, including smoke-style tests and praise for reduced dust blowback.

The DuoClean two-roller, power-fin style floorhead earns frequent praise for smooth transitions and strong pickup, but its bulk can make narrow reach harder.

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.

Most reviews say hair wrap is minimal thanks to a self-cleaning brushroll design, though one stress test still reported tangling under heavy hair conditions.

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 a standout strength in many tests, though ultra-fine sand or sugar may need an extra pass or a higher power setting.

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.

Large debris pickup is consistently strong with little scatter reported, handling cereal, rice puffs, and other chunky messes well.

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.

LED headlights are frequently mentioned as helpful for spotting dust; a few sources differ on whether a headlight is included in specs, but hands-on reviews generally report usable LEDs.

Despite a bulky head overall, several reviewers note it can still get under some cabinets or low furniture when paired with the flexible wand.

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.

Maintenance is usually described as low effort due to washable filters and reduced hair wrap; cleaning the dust cup after fine powders can be the most annoying routine task.

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 reasonable in Eco/auto modes in at least one measurement, but it becomes noticeably loud in Boost and when the dirt sensor ramps power.

The odor-neutralizer cartridge is polarizing: some love the fresh scent while others find it too strong or unnecessary. It can also introduce ongoing cartridge costs.

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.

Beyond filters and batteries, the optional scent cartridges can add a small recurring cost, and some reviewers wish spare filters were included for the price.

No summary yet.

At least one hands-on review calls the packaging minimal and largely recyclable, with little unnecessary filler.

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 consistently report strong hair pickup on floors and furniture, making it a reliable choice for routine pet messes.

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).

Value perceptions hinge on price: at full MSRP it is often labeled expensive, but it is frequently viewed as a strong buy when discounted, especially versus premium cordless rivals.

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.

Eco runtimes around an hour are frequently cited, while sensor/auto modes are commonly closer to the 20–30 minute range depending on surface and usage. Boost or Max runtime is short in testing (around 10–11 minutes), which is typical for high-power cordless sticks.

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.

Stair cleaning is doable, especially in handheld mode, but several reviewers call out the head weight as tiring when doing stairs with the full unit.

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 MultiFLEX hinge lets the vacuum fold down for compact, often freestanding storage. A minority of reviewers note it may not stand fully upright as securely as a docked unit.

A few users note the brush can grab small objects like cords or fabric if you are not careful, but these clogs are usually easy to clear without damage.

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.

Most reviewers describe suction as genuinely strong for a cordless stick, with some tests measuring class-leading numbers for Shark. A few sources note it is not the absolute strongest versus premium competitors, and power use rises quickly in high modes.

A longer warranty period is a recurring highlight, though some reviewers still recommend buying with coverage because repairability can be a concern for cordless sticks in general.

Swapping attachments and switching into handheld mode is generally quick and straightforward, which helps for spot-cleaning and tight spaces.

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.

The MultiFLEX bending wand is repeatedly highlighted for under-furniture reach and reducing how much you need to bend down while vacuuming.

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 cleaning is generally effective on upholstery and tight spots, but multiple sources note the lack of a powered upholstery tool in the box.

Versatility is a strength: it works across mixed floors, folds for storage, and converts to handheld for above-floor tasks. It is not a wet/dry or self-empty system, so it stays focused on vacuuming.

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 common ergonomic complaint, with many calling it heavier than peers and sometimes top- or head-heavy, especially on stairs.
