Side-by-Side Comparison
| Spec | Samsung Bespoke AI Jet Ultra (VS90F40DMK/AA) | Shark PowerDetect Cordless Stick Vacuum (IP1251) |
|---|---|---|
| Price | $847.00 | $349.99 |
| Release Year | 2025 | 2024 |
| Machine Type | Dry cordless stick vacuum with a bagged auto-empty Clean Station | Dry cordless stick vacuum, converts to handheld |
| Suction (as published) | 400 air watts. Samsung publishes air watts, so this is directly comparable with Dyson's 240 AW rather than a Pa number | Sources conflict, and none is a suction figure: SharkNinja publishes no air watts and no Pa, describing it only as 'Shark's most powerful cordless suction' under ASTM F558 in Boost. Abt's spec sheet lists 380 W at 21.6 V, which is input power drawn, not suction delivered |
| Runtime, Eco / Headline (min) | 100✓ | 70 |
| Runtime, Max Power (min) | 16 | Not published by the manufacturer — Shark quotes only 'up to 70 minutes' |
| What the Runtime Claim Actually Means | Samsung publishes the whole table instead of a single best case: 100 minutes on minimum, 49 on mid, 16 on max and 1 minute in Jet mode. The 100-minute headline is the lowest setting | SharkNinja states the 70 minutes is ECO mode at the handheld unit — no wand, no powered floor head. Shark publishes no figure at all for Boost with the DuoClean Detect nozzle fitted |
| Removable Battery | Sources conflict: Samsung and RC Willey list the battery as removable, while Abt's spec sheet for the same SKU lists it as non-removable. One battery is included either way | Yes — removable 21.6 V pack, but only one is included |
| Spare Battery | Not published by the manufacturer | Not published by the manufacturer; Shark does not list a price on the product page. Third-party XBATR-series replacements are widely sold |
| Dock / Wall Mount | All-in-One Clean Station included — free-standing, charges, stores tools and auto-empties. Needs roughly 14 inches of floor width | Charging stand and charging cord included. The PowerDetect auto-empty base is a separate product (IP3251) and cannot be added to this one later |
| Filtration | Multi-cyclonic with HEPA; Samsung claims 99.999% of fine dust captured. The station is bagged, so emptying never exposes you to the dust | Sources conflict: SharkNinja lists felt and washable-foam pre-motor filters plus a HEPA post-motor filter, while Abt's spec sheet for the same SKU says 'no HEPA filter'. Shark does not claim its Anti-Allergen Complete Seal on this cordless model, though it does on the corded PowerDetect |
| Bin / Tank Capacity | 0.5 L on-board bin; 2 L bagged Clean Station, which Samsung says holds up to two months of debris | 0.7 qt (23.68 oz) dust cup with a bottom-release flap — debris drops out but your hand stays above the opening |
| Weight (lbs) | 7✓ | 7.96 |
| Filters, Consumables & Self-Clean | The Clean Station uses disposable dust bags — three in the box, more must be bought, and that is the permanent running cost. On-board filters are washable | Foam and felt pre-motor filters are washable and Shark specifies a monthly rinse. Replacement brushrolls and filters are stocked by SharkNinja |
| Warranty | 24 months | 60 months |
| Colors | Satin Black | Dark Gray, Navy, Purple/Gray, Teal |
Category Scores
Suction Power
The Samsung Bespoke AI Jet Ultra (VS90F40DMK/AA) leads clearly here, 10.0 against 8.5 — a 1.5-point margin on actual cleaning force at the head, judged on air watts where a maker publishes them and discounted where only Pa or motor watts are quoted. If that is what you are buying for, the Shark PowerDetect Cordless Stick Vacuum (IP1251) does not close the gap elsewhere.
Sustained Runtime
The Samsung Bespoke AI Jet Ultra (VS90F40DMK/AA) leads clearly here, 6.5 against 5.5 — a 1.0-point margin on how long the machine really runs on max power with the motorised floor head attached — not the eco-mode, bare-tool figure on the box. If that is what you are buying for, the Shark PowerDetect Cordless Stick Vacuum (IP1251) does not close the gap elsewhere.
Filtration & Sealing
The Samsung Bespoke AI Jet Ultra (VS90F40DMK/AA) leads clearly here, 9.0 against 6.5 — a 2.5-point margin on whether the whole machine is sealed or a HEPA element simply sits inside a leaky body, and what the claimed rating is actually measured at.

Handling & Ergonomics
The Shark PowerDetect Cordless Stick Vacuum (IP1251) leads clearly here, 8.0 against 7.5 — a 0.5-point margin on weight, balance, whether power is a push-button or a trigger you must hold, and how it stores. If that is what you are buying for, the Samsung Bespoke AI Jet Ultra (VS90F40DMK/AA) does not close the gap elsewhere.
Maintenance & Emptying
The Samsung Bespoke AI Jet Ultra (VS90F40DMK/AA) leads clearly here, 9.0 against 7.5 — a 1.5-point margin on bin or tank emptying, whether your hand ends up near the dust, self-clean quality and the ongoing cost of filters, bags and detergent. If that is what you are buying for, the Shark PowerDetect Cordless Stick Vacuum (IP1251) does not close the gap elsewhere.
Battery System
The Samsung Bespoke AI Jet Ultra (VS90F40DMK/AA) leads clearly here, 7.0 against 6.5 — a 0.5-point margin on removable or sealed, how many packs are included, what a spare costs and whether the pack is shared across a range. If that is what you are buying for, the Shark PowerDetect Cordless Stick Vacuum (IP1251) does not close the gap elsewhere.
Versatility
The Samsung Bespoke AI Jet Ultra (VS90F40DMK/AA) leads clearly here, 8.0 against 7.5 — a 0.5-point margin on handheld conversion, above-floor tools, carpet capability and wet-mopping ability. If that is what you are buying for, the Shark PowerDetect Cordless Stick Vacuum (IP1251) does not close the gap elsewhere.
Value
The Shark PowerDetect Cordless Stick Vacuum (IP1251) leads clearly here, 8.5 against 6.0 — a 2.5-point margin on what you actually get for the street price once consumables and missing accessories are counted. If that is what you are buying for, the Samsung Bespoke AI Jet Ultra (VS90F40DMK/AA) does not close the gap elsewhere.

Pros & Cons
Samsung Bespoke AI Jet Ultra (VS90F40DMK/AA)
Pros
- +400 air watts, published in the same unit Dyson uses — the strongest honestly comparable number on this page
- +Samsung publishes a complete per-mode runtime table rather than one best case; almost nobody else in the category does
- +The bagged Clean Station empties the vacuum for you and keeps your hands out of the dust entirely
- +10-year motor warranty and full SmartThings integration
Cons
- −Jet mode — the setting that produces the 400 AW headline — runs for one minute
- −The Clean Station needs about 14 inches of floor width and is loud enough to be a problem near a bedroom
- −Bags are a permanent consumable; LG's rival tower is bagless
- −Street price has swung between roughly $500 and $1,100 within a year, and stock has been patchy at Best Buy, Samsung and Abt
Shark PowerDetect Cordless Stick Vacuum (IP1251)
Pros
- +The MultiFLEX wand folds so it stands on its own and lies flat under a sofa — Dyson has no equivalent at any price
- +Push-button power rather than a held trigger, which is the ergonomic complaint people actually leave Dyson over
- +5-year limited warranty on the unit is by far the longest here
- +Detection genuinely modulates suction by floor type and dirt level rather than just lighting up an icon
Cons
- −The 70-minute claim is ECO at the bare handheld with no wand or floor head — the honest working figure is much lower and Shark publishes none
- −Shark publishes neither air watts nor Pa, so this machine cannot be compared on paper against anything else in the category
- −Sources disagree on whether this SKU even has a HEPA filter, and Shark pointedly does not claim a sealed anti-allergen system on it
- −One battery in the box and no published spare-battery price
