3.1
Battery is the most common limitation: typical runtime is short and charging can be slow, and the battery is not treated as easily swappable in the reviews.
Bin and Bag
P1
Product 1: Black+Decker Dustbuster AdvancedClean Handheld Vacuum
4.1
The bagless, translucent bin makes it easy to see fill level and is sized for quick jobs; large messes can fill it quickly, requiring more frequent emptying.
P2
Product 2: Shark UltraCyclone Pro Cordless Handheld...

Controls and UI
P1
Product 1: Black+Decker Dustbuster AdvancedClean Handheld Vacuum
4.0
Controls are generally simple (on/off switch) and the pivot/rotation locks into positions, but a couple reviewers say rotating/pivoting can feel finicky or unnecessary.
P2
Product 2: Shark UltraCyclone Pro Cordless Handheld...
4.6
Controls are simple and intuitive, with easy on/off operation and basic indicator lights for charging or low battery.
Cordless convenience
P1
Product 1: Black+Decker Dustbuster AdvancedClean Handheld Vacuum
4.7
Cordless convenience is widely valued for cars, quick kitchen/table cleanups, and small spills, but only holds if you can store it on the dock so it stays charged.
P2
Product 2: Shark UltraCyclone Pro Cordless Handheld...
4.7
Being cordless is a major convenience for quick daily cleanups around the home and in the car.
Crevice / Groove Pickup (Hard Floors)

Ease of use is a major strength: quick grab-and-go operation, simple switch, and a dock that encourages frequent use for small daily messes.
P2
Product 2: Shark UltraCyclone Pro Cordless Handheld...
4.2
Operation is straightforward (single-button style) and the form factor is easy to maneuver, though the longer, slim body can be limiting in very cramped spaces.
Emptying and Mess Control
P1
Product 1: Black+Decker Dustbuster AdvancedClean Handheld Vacuum
4.0
Emptying is usually described as quick and straightforward with release buttons, but some users report awkward handling, potential spillage, or debris leakage if the nozzle is pointed down after use.
P2
Product 2: Shark UltraCyclone Pro Cordless Handheld...
4.2
One-button emptying is usually easy and touchless, but some reviewers found the mechanism a bit fiddly or warned it can scatter debris if you do not aim carefully.
Filtration / Dust Containment
P1
Product 1: Black+Decker Dustbuster AdvancedClean Handheld Vacuum
2.4
Filtration is a recurring complaint: it is not HEPA and multiple reviews report fine dust is hard to capture or can pass through/exhaust, though some owners find it acceptable for larger crumbs and typical household debris.
P2
Product 2: Shark UltraCyclone Pro Cordless Handheld...
4.0
Filters are typically washable (foam or felt styles), but HEPA-level containment is not consistently claimed and some guidance suggests periodic replacement.
Hair Pickup — Hard Floors

Fine dust pickup is inconsistent: some tests show it struggles with flour and powdery debris, and some users report fine dust escaping through exhaust.
P2
Product 2: Shark UltraCyclone Pro Cordless Handheld...
4.2
Fine dust and small particles on hard floors are handled well with the crevice tool and careful passes; powered tools can scatter on slick surfaces in some tests.
Hard Floor — Large Debris Intake
P1
Product 1: Black+Decker Dustbuster AdvancedClean Handheld Vacuum
4.2
Large debris pickup is generally strong for handheld use (cereal, rocks, leaves, crumbs) according to both tests and real-world car/household cleanups.
P2
Product 2: Shark UltraCyclone Pro Cordless Handheld...

Onboard tool storage
P1
Product 1: Black+Decker Dustbuster AdvancedClean Handheld Vacuum
4.5
Onboard storage is a standout: tools are built in, so there is nothing separate to lose, and this is consistently cited as a convenience win.
P2
Product 2: Shark UltraCyclone Pro Cordless Handheld...
2.7
There is typically no built-in attachment storage, and multiple reviewers note the lack of a dedicated place for tools or a dock.
Ongoing ownership costs (bags, filters, batteries)

Pet-Ready Features
P1
Product 1: Black+Decker Dustbuster AdvancedClean Handheld Vacuum

Pet readiness is generally weak: multiple tests/reviews report it struggles with pet hair, especially when hair is embedded in upholstery or carpet fibers.
P2
Product 2: Shark UltraCyclone Pro Cordless Handheld...
4.5
Pet-focused performance is a highlight: the motorized pet tool pulls hair from couches, carpets, and car interiors, though embedded or wiry hair can require extra passes.
Price and Value
P1
Product 1: Black+Decker Dustbuster AdvancedClean Handheld Vacuum
3.6
Value is often rated high (especially at sale prices) because it is convenient and capable on everyday debris, but looks weaker when judged against stronger handhelds for fine dust, pet hair, or longer runtimes.
P2
Product 2: Shark UltraCyclone Pro Cordless Handheld...
4.6
Value is generally rated highly for a mid-priced handheld, especially for pet households wanting strong everyday pickup.
Runtime
P1
Product 1: Black+Decker Dustbuster AdvancedClean Handheld Vacuum

The dock keeps storage tidy for many, but at least one household disliked the corded base for drawer storage and found the charging contact alignment easy to mess up.
P2
Product 2: Shark UltraCyclone Pro Cordless Handheld...
3.0
Storage is a recurring complaint: no included stand or dock in several packages, and some wish for a wall mount or more compact countertop storage.
Suction and Airflow
P1
Product 1: Black+Decker Dustbuster AdvancedClean Handheld Vacuum
4.0
Suction/airflow is described as strong by several owners for everyday crumbs and car debris, but at least one test-based review calls suction weak and another bench comparison places it mid-pack for lift despite decent airflow.
P2
Product 2: Shark UltraCyclone Pro Cordless Handheld...
4.3
Suction is widely described as strong for a handheld, especially for surface crumbs and hair, but it is less convincing on deeply worked-in dirt and some heavy debris.

No score yetUpholstery / Above-Floor Pickup
P1
Product 1: Black+Decker Dustbuster AdvancedClean Handheld Vacuum
2.8
Above-floor and upholstery cleaning is okay for crumbs and surface dirt, but embedded pet hair is a common failure point.
P2
Product 2: Shark UltraCyclone Pro Cordless Handheld...
4.4
Above-floor cleaning is a core strength for cars and upholstery, but some mention the nozzle can cling to fabric or requires the right angle for best results.
