The Shark Stratos Cordless IZ862H ($320) is the right cordless stick vacuum for ~80% of US households in 2026. The Dyson V15 Detect Absolute ($830) is the right answer only if you have severe allergies, want the laser tech, or buy once for ten years.
⚠️ Skip the Dyson if you don't have allergies and don't need the laser; skip the Shark if you have asthma, diagnosed dust-mite allergy, or plan to keep this vacuum 8+ years. Scenario routing below.
Verdicts synthesized from Wirecutter, Vacuum Wars, Consumer Reports, RTINGS, Tom's Guide, The Spruce, manufacturer specs, and the ScraperAPI Amazon listing snapshot.
How do the Dyson V15 and Shark Stratos compare side by side?
Ten dimensions that move the buying decision, with manufacturer-spec values verified against the ScraperAPI Amazon listing snapshot (2026-05-04). The winner column is per-row factual (lower price, longer warranty, certified seal), not an overall recommendation — that lives in §8.
| Dimension | Dyson V15 Detect Absolute | Shark Stratos IZ862H | Winner |
|---|---|---|---|
| Suction power | 230 AW (Boost mode) | ~150-180 AW peak (independent test) | Dyson |

| Price (Amazon, 2026-05-04) | $830 | $320 | Shark |
Per-row verdicts are factual (lower price, certified seal, longer field lifespan). Overall recommendation by scenario lives in §5 below — and resolves cleanly to one product per scenario, never "it depends."
Where does the Dyson actually win?
Four scenarios where the Shark Stratos cannot match the Dyson V15 — these are the real differences the $510 price gap actually buys.
1. Severe allergy and asthma households — full-machine HEPA seal
The Dyson V15 is independently certified as a full-machine sealed HEPA system: the entire body is sealed end-to-end, so exhaust air is verifiably cleaner than intake. The Shark Stratos uses a HEPA filter rated to capture 99.97% of particles down to 0.3 microns at the filter element, but Shark does not certify the body itself as a sealed system — independent teardowns (RTINGS, Vacuum Wars) confirm exhaust air can leak around body seams before reaching the HEPA filter. For typical homes without diagnosed allergies, the difference is academic; both vacuums improve indoor air quality. For households with diagnosed dust-mite allergy or asthma, this is the medically meaningful difference: Dyson's full-machine seal is the only one of these two products you can trust to not redistribute the very allergens you're trying to remove.
2. Tech enthusiasts — laser dust detection and particle counting
The Dyson V15's Slim Fluffy cleaner head projects a green laser onto the floor at a 1.5° angle, illuminating microscopic dust the human eye cannot see — the kind of dust most people walk past without noticing. Paired with the acoustic piezo sensor in the bin path that counts and sizes particles in real-time on the LCD screen, you get genuine quantified feedback on whether a floor is actually clean. The Shark Stratos has Clean Sense IQ, which auto-adjusts suction up when it detects more debris, but no laser visualization and no on-screen particle data. For tech-curious owners who like instrumented appliances, and for homes where cleaning thoroughness needs to be confirmed (immunocompromised members, premature-baby households), the laser is a real differentiator and not gimmickry.
3. Multi-floor homes — lighter weight matters on stairs
At 6.8 lbs, the Dyson V15 is meaningfully lighter than the 8.4 lb Shark Stratos — a 1.6 lb difference is small at the kitchen counter but real on the seventh stair carrying the vacuum to the upstairs hallway. For two-story homes where the cordless stick is the daily upstairs cleaner, the Dyson's weight advantage compounds across years of use. The MultiFLEX wand on the Shark partially offsets this for under-furniture reach (the Shark wins that scenario, see §4), but for stair-carry-heavy households the Dyson's lighter chassis is the ergonomic win.
4. Buy-once households — 8-10+ year durability beats Shark's 3-5
Dyson's reputation is built on cordless stick motors that run 8-10+ years in field reports, with replaceable batteries and filters that keep the unit serviceable post-warranty at Dyson-authorized centers. The V15 ships with a 5-year limited warranty covering parts plus labor. Shark Stratos ships with a 5-year motor warranty but only a 1-year battery warranty — and field reports cluster motor or switch failures at 3-5 years on heavy use. For a household that uses the cordless stick 4-5 times per week as the primary floor cleaner, the Dyson's longer lifespan eventually flips the math: across 8 years of ownership at one Dyson vs two Sharks (~$640 cumulative), the gap closes meaningfully and the Dyson buys consistency the Shark replacement cycle does not.

Price as of May 5, 2026
Pros:
- Full-machine HEPA seal — independently certified to capture 99.99% of particles down to 0.3 microns across the entire body; exhaust air is cleaner than intake. Medically meaningful for severe-allergy and asthma households.
- Green laser dust detection + acoustic piezo particle counter + LCD screen — real instrumented cleaning, not gimmickry. Lets you confirm a floor is actually clean by particle count.
- 6.8 lbs is genuinely light — 1.6 lbs lighter than the Shark Stratos, which compounds across years of stair-carry in two-story homes.
- 5-year limited warranty + Dyson-authorized service network + 8-10+ year field-reported lifespan — buy-once ergonomics for households that keep appliances a decade.
Cons (honest weight):
- $829.99 is real money — about 2.6× the Shark Stratos. For households without severe allergies, on mostly hardwood, with average pet hair, the math never pays back.
- Narrow Amazon listing depth — 40 ratings on this specific Absolute variant. The parent V15 Detect SKU has more aggregate reviews across child variants, but each child reads its own count.
- Bin emptying is fiddly — 0.20 gal capacity means more frequent emptying for large homes; the point-and-shoot trigger emptying can spray fine dust if you don't hold the bin downward at the trash can.
- Boost mode burns battery fast — 60 min eco runtime drops to 8-10 min on Boost when motorized tools are running. Plan recharge windows for whole-home cleaning passes.
M's Verdict
Right answer for severe allergies, asthma, tech enthusiasts who want the laser, and households planning a 10-year hold. The full-machine HEPA seal is the underrated feature — and the actual reason to pay $510 more.
Where does the Shark actually win?
Four scenarios where the Shark Stratos isn't a compromise — it's the right answer, even if money were no object. Plus the honest read on its 3.9★ rating.
1. Daily mixed-floor cleaning at the price of an air fryer
The Shark Stratos's DuoClean PowerFins HairPro head pairs a soft fluffy roller with a stiff-bristle PowerFin roller — the dual-brushroll system handles hardwood, low-pile carpet, and area rugs in a single pass without changing tools. On hardwood specifically, the soft roller picks up large debris and fine dust without the scratching that single-stiff-bristle vacuums can cause; on carpet the PowerFin roller grabs embedded dirt and pet hair. Independent reviewer consensus (Wirecutter, Vacuum Wars) puts the Shark at parity with the Dyson V15 on hardwood and within 10-15% of the Dyson on carpet — at one-third the price. For households whose floors are 70%+ hardwood with average pet hair, the Shark covers the workload and the $510 difference is real opportunity cost.
2. The MultiFLEX wand reaches places the Dyson can't
The Shark Stratos's MultiFLEX wand bends 90 degrees mid-shaft, letting the cleaner head slide flat under low furniture — sofas with skirts, bed frames, low cabinets — without the user bending over or kneeling. The Dyson V15 has no equivalent feature: to clean under low furniture you either pull the furniture out or get on the floor. For households with lots of low-clearance furniture (most American homes have at least one sofa with a skirt and one bed frame too low to reach under), the MultiFLEX is genuinely more functional than the Dyson's lighter weight. This is the rare scenario where the Shark's ergonomics beat the Dyson's outright.
3. Pet households that aren't severe-allergy households
The Shark Stratos was engineered for pet households without severe allergies: the Anti-Odor Neutralizer Technology uses replaceable cartridges that absorb pet odors during vacuuming (most owners report cartridge changes every 3-6 months at $5-$8 each), the DuoClean PowerFins HairPro head has anti-tangle geometry that handles long human and dog hair without the wrap-and-snap issues common in single-roller vacuums, and the larger 0.21 gal bin handles a pass through a multi-pet living room without mid-vacuum emptying. For a typical American pet household — moderate shedding, no diagnosed allergies — the Stratos is the right answer at one-third the price of the Dyson, and the Anti-Odor + DuoClean combination is genuinely better than the Dyson V15 for the pet-specific use case (Dyson has no Anti-Odor system).
4. The 3.9★ rating: what it really tells you
On Amazon as of 2026-05-04, the Shark Stratos IZ862H Ash Purple shows ★3.9 across 1,315 ratings — meaningfully lower than the Dyson V15 Detect Absolute's ★4.4 across 40 ratings. This is the elephant in the room and worth addressing head-on. The 1- and 2-star Shark reviews cluster around three issues: motor or switch reliability after 12-18 months on heavy use, the battery degrading inside the 1-year warranty window (unlike the 5-year motor warranty), and the bin-empty mechanism getting clogged with hair on heavy pet households. None of these are same-day capability complaints — the Shark cleans well out of the box. They are longevity complaints. If you plan to keep the vacuum 5+ years and use it 4-5 times per week, the Dyson is the safer empirical bet. If you replace appliances every 3-4 years anyway (the cluster where most American households actually sit), the Shark's upfront $510 saved fully absorbs the durability-risk premium and the math stays Shark-favorable. Worth knowing, not worth panicking over.
Where to buy
SharkClean.com — Check current price · Target — Check current price
Price as of May 5, 2026
Pros:
- $319.99 retail — about 39% of the Dyson V15 price, with frequent dips to $279-$299 during Prime Day, Black Friday, and Costco rotation.
- MultiFLEX bend-down wand reaches under low furniture without the user bending over — a feature the Dyson V15 has no equivalent for.
- DuoClean PowerFins HairPro dual-roller geometry handles hardwood, carpet, and pet hair in a single pass without tool changes; anti-tangle for long human and dog hair.
- Anti-Odor Neutralizer Technology with replaceable cartridges ($5-$8 every 3-6 months) is genuinely useful in pet households — Dyson has no equivalent system.
Cons (honest weight):
- 3.9★ aggregate is a long-term-durability signal — 1- and 2-star reviews cluster around motor/switch reliability after 12-18 months and battery degradation inside the 1-year warranty.
- HEPA filter, not full-machine seal — RTINGS teardowns confirm body-seam exhaust leaks. For severe-allergy or asthma households, this is medically meaningful and the Dyson is the right call instead.
- 8.4 lbs is on the heavier side — 1.6 lbs heavier than the Dyson V15, which compounds in two-story homes where the cordless stick is carried up and down stairs daily.
- 1-year battery warranty is the weakest part of the warranty package — plan for a battery replacement at year 2-3 ($60-$80) rather than at the 5-year motor warranty horizon.
M's Verdict
Right answer for ~80% of US households — daily mixed-floor cleaning runs cleanly at 39% the Dyson price, the MultiFLEX wand beats Dyson on under-furniture reach, and the Anti-Odor cartridges actually work in pet households. The 3.9★ is a 5+ year durability concern, not a same-day capability one.
Use Case Matrix: which vacuum for which home?
Eight atomic scenarios, each routed cleanly to one vacuum — never "it depends." Match your household to the row that fits closest.
| Your home | Pick | Why |
|---|---|---|
| Severe-allergy or asthma household | Dyson V15 | Full-machine HEPA seal certification is the only one of these two products to keep allergens contained end-to-end. Independent teardowns show the Shark's body has seam leaks before exhaust hits the filter — medically meaningful at this severity. |
| Mixed-floor pet household, no severe allergies | Shark Stratos | DuoClean PowerFins HairPro is anti-tangle for long human and dog hair, Anti-Odor cartridges genuinely work in pet kitchens, MultiFLEX reaches under sofas. At 39% of Dyson price, the Shark is purpose-built for this use case. |
| Tech enthusiast — wants laser dust visualization + particle counter | Dyson V15 | Green laser on Slim Fluffy head + acoustic piezo particle counter + LCD screen are real instrumented cleaning. Shark Stratos has Clean Sense IQ but no visualization or particle data — Dyson is the only option here. |
| Two-story home — vacuum carried up and down stairs daily | Dyson V15 | 6.8 lbs vs 8.4 lbs is small at the counter but compounds across years of stair-carry. For households where the cordless stick is the daily upstairs cleaner, Dyson's lighter chassis is the ergonomic win. |
| Hard budget under $400 — first cordless stick buyer | Shark Stratos | Dyson V15 cannot fit under $400 even on Dyson Outlet ($579-$649 for refurb). Shark Stratos at $319.99 retail (frequently $279-$299 on promo) covers the budget without compromise on capability. |
| Small apartment — under 1,000 sqft, mostly hardwood, occasional cleaning | Shark Stratos | For 1-2 cleaning sessions per week on hardwood, the Shark covers the workload at parity to Dyson. MultiFLEX wand handles low-clearance apartment furniture; the $510 saved funds a robot vacuum on top. |
| Family with young kids — frequent spills, multiple users | Shark Stratos | Multi-user cordless sticks get dropped, banged, and sometimes destroyed. $319.99 absorbs the inevitable damage where $829.99 doesn't. DuoClean handles cracker crumbs and Cheerios cleanly on first pass. |
| Buy-once-use-ten-years mindset — heavy use, 4-5 times per week | Dyson V15 | 5-year limited warranty + Dyson-authorized service network + 8-10+ year field lifespan beats Shark's 3-5 year cluster. By year 8 you'll have bought 2 Sharks (~$640) vs one Dyson — gap closes meaningfully. |
Final tally: Shark Stratos wins 4 of 8 scenarios (mixed-floor pet, sub-$400 budget, small apartment, family with kids); Dyson V15 wins 4 (severe allergy, tech enthusiast, two-story stairs, buy-once 10 years). The split is closer than the Vitamix vs Ninja comparison — vacuums vary more by household needs than blenders. Most US households without severe allergies fall into Shark's scenarios; that's the ~80% number and that's why §8 lands where it lands.
What does the price gap actually look like in 2026?
Live retail (ScraperAPI snapshot, 2026-05-04): Dyson V15 Detect Absolute at $830, Shark Stratos Cordless IZ862H at $320. The price gap is roughly $510 — about half a year of premium streaming subscriptions or a full mid-tier appliance category outright (a top-rated air purifier plus a budget robot vacuum, combined).
Three paths cut the Dyson premium meaningfully. First, the Dyson Outlet (refurbished store on dyson.com) sells factory-refurbished V15 Detect units at roughly $579-$649 (a 22-30% discount) with a 12-month warranty (vs 5 years on new). Inventory rotates fast and exact V15 Detect Absolute bundles are not always in stock; signing up for the Dyson email list catches them. Second, Best Buy and Costco rotate V15 promotions several times a year — Memorial Day, Prime Day-adjacent weeks, Black Friday, and post-Christmas clearance often drop the V15 Detect to $649-$699 with full warranty. Third, the V12 Detect Slim sibling (~$549, lighter at 5.2 lbs, narrower body, 60-min runtime) has the same laser detection as V15 at a $300+ discount — for households that want the Dyson tech but not the V15's full power, this is a meaningful alternative inside the Dyson family.
The Shark Stratos promo cycle is reliably aggressive: Prime Day, Black Friday weekend, and SharkClean.com's own clearance events drop the IZ862H to $279-$299 several times per year. If you can wait, the effective price gap widens to closer to $570 ($579 Dyson Outlet vs $279 Shark promo).
Dollar-per-year analysis. A household using the cordless stick 4-5 times per week over an 8-year horizon: Dyson V15 at $829.99 with same unit still serviceable = ~$104/year; Shark Stratos at $319.99 with one replacement at year 4 (likely battery + maybe full unit) = ~$640 cumulative = ~$80/year. For typical 4-5x weekly use, the Shark is still ~$24/year cheaper across 8 years even after factoring replacement. The math flips Dyson-favorable only at year 9-10+ on heavy use, or earlier if your household keeps the vacuum 10+ years and the Dyson runs the full distance while the Shark needs a third replacement.
What if neither one is right?
Three alternatives cover scenarios where this binary doesn't fit cleanly.
Tineco Pure ONE S15 Pet ($349) — smart sensor at Shark price
The Tineco Pure ONE S15 Pet has an iLoop dust sensor that auto-adjusts suction (similar to the Dyson's acoustic piezo idea, executed at a Shark price point), a self-cleaning brush roll, and a Pet bundle that includes a mini motorized tool for upholstery. It's the right pick for buyers who want some of the Dyson smart-detection tech without the Dyson premium, and don't need full-machine HEPA seal certification. ★4.4 across 3,200+ reviews on Amazon — a meaningfully deeper data point than the Shark Stratos's ★3.9. Check Tineco Pure ONE S15 →
Samsung Bespoke Jet AI ($699) — design-led with self-empty base
The Samsung Bespoke Jet AI is the design-conscious pick: a self-empty base means you only handle the bin once a month instead of every cleaning session, the AI-powered floor detection auto-adjusts suction to surface type, and the all-in-one base also charges and self-cleans. At $699 it's priced between the Shark and Dyson — for kitchens prioritizing aesthetics and the convenience of self-empty (a Dyson V15 doesn't have this; you empty manually), it's the right call. Check Samsung Bespoke Jet AI →
If you actually want a robot vacuum instead — see our Best Robot Vacuums guide
Cordless stick vacuums and robot vacuums solve different problems. Robot vacuums handle the daily 60-90% of dust and debris automatically while you do other things; cordless sticks handle the deep clean, the spill, the under-furniture reach, the stairs. Most American households eventually own both (a robot for the daily, a cordless stick for the weekly), and many readers landing on this comparison were really asking "which vacuum should I buy first?" — for which the answer is often a robot vacuum in the $500-$1,500 tier, with a cheap stick vacuum kept for spot cleaning. See our Best Robot Vacuums 2026 guide →
Which one should you buy?
For most US households in 2026: the Shark Stratos Cordless IZ862H ($320). The math is real but not overwhelming — daily mixed-floor cleaning at parity to Dyson on hardwood and within 10-15% on carpet, the MultiFLEX wand is genuinely better for under-furniture reach, the Anti-Odor cartridges work in pet households, and the $510 saved either funds the next major appliance category outright or sits in your pocket. The 3.9★ rating is a 5+ year durability concern worth knowing about, not a same-day capability concern — for households who replace appliances every 3-4 years anyway (the cluster where most Americans actually live), the price advantage stays intact.
For four specific scenarios, the Dyson V15 Detect Absolute ($830) is the right answer instead:
- 📌 You have diagnosed dust-mite allergy or asthma — Dyson's full-machine HEPA seal is medically meaningful and the Shark's filter-only HEPA is not the same product at this severity.
- 📌 You want the laser dust detection + particle counter LCD — only the Dyson V15 has these; they're real instrumented cleaning, not gimmickry.
- 📌 Your home is two stories with daily stair-carry — 6.8 lbs vs 8.4 lbs compounds meaningfully across years of upstairs vacuuming.
- 📌 You plan to keep this vacuum 8+ years on 4-5x weekly heavy use — Dyson's 8-10+ year field-reported lifespan beats Shark's 3-5 year cluster, and the math flips Dyson-favorable past year 6-7.
For households that fit two or more of those scenarios (e.g., severe-allergy plus 10-year buyer, or two-story with diagnosed asthma), the Dyson is the unambiguous right answer. For households that fit none — most American homes without severe allergies, on mostly hardwood, with average pet hair, replacing appliances every few years — the Shark Stratos is the honest call and the $510 stays where it can do other work in the household budget.
Frequently asked questions
Dyson vs Shark which is better?
Depends on what you prioritize. The Shark Stratos Cordless IZ862H ($319.99) is the right cordless stick vacuum for roughly 80% of US households in 2026 — daily cleaning across mixed hardwood and low-pile carpet runs cleanly at 39% of the Dyson price. The Dyson V15 Detect Absolute ($829.99) is the right vacuum only for severe-allergy or asthma households (full-machine HEPA seal), tech enthusiasts who want the laser dust detection + LCD particle counter, and 10-year-buy-once households where Dyson durability beats Shark's. The honest answer: if you have severe allergies or plan to keep the vacuum 8+ years, the Dyson is better; otherwise the Shark is the right call.
Is a Dyson V15 really worth 2.6x the price of a Shark Stratos?
For three specific scenarios, yes. Severe allergies and asthma are medically meaningful — the Dyson V15's full-machine HEPA seal certification is something the Shark's filter-only HEPA does not match in independent teardowns. The laser dust detection is a real differentiator that lets you see microscopic dust the human eye cannot, plus the acoustic piezo sensor counts particles on the LCD. And the field-reported 8-10+ year Dyson lifespan vs the Shark's 3-5 year cluster makes the math closer than $510 looks at the cash register. For five other scenarios — daily mixed-floor cleaning, sub-$400 budget, small apartment, family with kids, mostly hardwood without severe allergies — the Shark covers the workload and the $510 funds the next appliance category outright.
Why does the Shark Stratos have 1,315 reviews and the Dyson V15 has 40?
Volume and listing structure. The Shark Stratos IZ862H Ash Purple is one of Shark's flagship cordless sticks with 5+ years on the market and broad mass-market distribution, accumulating 1,315 reviews on a single ASIN. The Dyson V15 Detect Absolute (B0CH5QWSGK) is a specific bundle variant; the parent V15 Detect SKU aggregates more total reviews across child variants but each variant ASIN reads its own count. The 33× review-count gap is partially a price-segment artifact (mass-market Shark sells more units than premium Dyson) and partially a listing-structure artifact (Dyson uses more child-variant ASINs than Shark). The signal in the rating gap (★4.4 vs ★3.9) is a long-term-durability difference — Shark's lower aggregate is driven by 1- and 2-star reviews flagging motor and switch reliability after 12-18 months, which is a real concern for buyers planning to keep the vacuum 5+ years.
Does the Shark Stratos have HEPA filtration like the Dyson V15?
Yes and no. The Shark Stratos ships with a HEPA filter rated to capture 99.97% of particles down to 0.3 microns AT THE FILTER. But Shark does not certify the entire vacuum body as a sealed system, and independent teardowns show exhaust air can leak around body seams before reaching the HEPA filter. The Dyson V15 is independently certified as a full-machine sealed HEPA system — the entire body is sealed so exhaust air is cleaner than intake. For typical homes without severe allergies, both vacuums improve indoor air quality meaningfully and the difference is academic. For households with diagnosed dust-mite allergy or asthma, the Dyson's full-machine seal is the medically meaningful difference — this is the scenario where the Dyson's price premium is genuinely buying medical-grade air filtration.
Is Shark made by the same company as Ninja?
Yes. SharkNinja Operating LLC owns both brands — Shark (vacuums and floor care) and Ninja (kitchen appliances including the Ninja Professional Plus blender). They share corporate infrastructure, manufacturing partnerships, and product-engineering pipelines, which is part of why both brands sell at meaningful price premiums to private-label competitors at similar performance tiers and at meaningful discounts to the segment leaders (Dyson on vacuums, Vitamix on blenders). For consumers, the SharkNinja parent company means similar value-engineering trade-offs in both brands: capable performance, mass-market price points, durability that trends 3-5 years on heavy use rather than the 8-10+ years premium-tier brands achieve.
Can a Shark Stratos clean hardwood floors well?
Yes — the DuoClean PowerFins HairPro head was specifically designed for mixed flooring and the Stratos handles hardwood as well or better than the Dyson V15 in independent reviewer consensus (Wirecutter, Vacuum Wars). The dual-brushroll system uses a soft fluffy roller paired with a stiff-bristle PowerFin roller, so it picks up large debris and fine dust on hardwood without the scratching that single-stiff-bristle vacuums can cause. The Shark MultiFLEX bend-down wand also reaches under low furniture (sofa skirts, beds) without the user bending over — a feature Dyson does not match. On hardwood specifically, the Shark Stratos is at parity with the Dyson V15 and the $510 saved is real value.
How long do Dyson and Shark vacuums actually last?
Dyson reputation is built on motors that run 8-10+ years in field use; the V15 ships with a 5-year limited warranty (parts + labor) at Dyson-authorized service centers, and post-warranty repair is feasible with replaceable batteries, filters, and brush bars. Shark Stratos ships with a 5-year limited motor warranty + 1-year battery warranty; field reports cluster at 3-5 years before motor or switch failure on heavy use, with the battery typically being the first component to fail. For a household that uses the cordless stick 4-5 times per week, the Dyson's longer lifespan means it pays back over 7-10 years even at 2.6× the upfront price. For a household that replaces appliances every 3-4 years anyway, the Shark's lower upfront cost absorbs the durability-risk premium and the math stays Shark-favorable.
Who wrote this and where's the data from?
Mubboo Editorial Team — independent US-market consumer-decision authority. We did not run hands-on testing for these vacuums; verdicts are synthesized from independent reviewer consensus (Wirecutter, Vacuum Wars, Consumer Reports, RTINGS, Tom's Guide, The Spruce), manufacturer specifications (dyson.com, sharkclean.com), and ScraperAPI Amazon Structured Data first-party listing snapshot (price/rating/reviewCount/featureBullets/images, retrieved 2026-05-04).
Editorial independence: the §8 winner is set independently of affiliate commission rates. The Dyson V15 carries the higher commission tier in the Amazon Associates schedule; we routed the Shark Stratos as the recommendation for the majority of scenarios despite this — the comparison answer is what serves the reader, not what serves the affiliate cell.
Editorial honesty on the 3.9★ rating: we addressed the Shark Stratos's 3.9★ aggregate (vs Dyson's 4.4★) head-on in §4 and §6 rather than hiding it. Real Amazon data flows directly into our buying recommendations — including data that complicates the recommendation.
Dynamic data: product prices and ratings refresh weekly via the ScraperAPI Tier-2 cron. Editorial body (M's Verdicts, Use Case Matrix winners, §8 final recommendation) is locked and only revised in the annual editorial review.
