Scorata scores summarize analyzed review evidence on a 1–5 scale; they are not laboratory measurements or a simple average of customer star ratings. Feature scores summarize the reviews covering that feature. The overall score averages feature scores within each review, then combines review averages. When both expert and customer evidence are available, those two groups receive equal weight. Products can have different review coverage, so small score gaps do not establish a winner.
Recommendations prioritize important features for the category, with a score of at least 3.5, a gap of at least 0.25 points and at least two supporting reviews per product. Features with widely varying scores or broad connectivity contexts are excluded from recommendations. These safeguards do not establish statistical significance.
Quick verdict
The review evidence points to a tradeoff: Suitability for small spaces and Overall opinion versus Floorhead design and Tool-change simplicity. Choose according to which strengths matter more to you; the overall score alone does not settle that choice.
Choose DEWALT 20V Handheld Cordless Vacuum for Suitability for small spaces and Overall opinion.
Choose Dyson Car + Boat Handheld Vacuum for Floorhead design and Tool-change simplicity.
Scores are out of 5. Missing scores mean missing review evidence, not a missing feature.
Reviewers repeatedly described the vacuum as easy, quick, ergonomic, or handy to use.
Ease of use is generally strong, with reviewers calling it simple, quick to understand and effective, apart from trigger-related caveats.
Large pieces were a clogging concern because the small inlet and hose can block on bigger debris.
One review praises the cyclone action for keeping the screen clear so suction does not fade.

Heavy-duty suitability is mixed: one review says it struggled with a major plant-soil mess, while another says it can handle bigger-than-average jobs.

Fine dust on hard floors performs very well in the available flour/sugar tests.

Overall sentiment is favorable, with most reviewers calling it powerful or excellent, while a few criticize the price and niche handheld-only design.
Weight feedback split by battery and use case: some called it heavy, while others found it light or manageable.
Weight feedback is mostly positive, though reviewers note it can feel heavier or bulkier than smaller handheld vacuums over time.
Crevice and groove pickup was strong, including a first-place sand-crevice result and good car-sand cleanup.
Crevice pickup is consistently praised, with reviewers highlighting seat gaps, narrow areas and hard-to-reach spots.
Emptying and mess control were generally praised, including easy chamber release, good sand retention, and a helpful flap.
Emptying is split between very easy, mess-free experiences and complaints that the mechanism initially feels awkward or stiff.
Above-floor and vehicle pickup was strong across couch, car, window-sill, and cabin-cleaning use cases.
Above-floor and upholstery pickup is a clear strength, especially on seats, sofas, furniture and cushion grooves, with only one stubborn-hair caveat.
The dustbin was praised as easy to remove, open, and empty, with the filter accessible inside.
The bin earns mostly positive comments for capacity and bagless emptying, but several reviewers still call it small or less refined than newer Dysons.
Large debris intake was split: one reviewer praised broad debris pickup, while others found the inlet too small for larger pieces.
Large hard-floor debris performance is mixed, ranging from 100% rice pickup to cereal and lentils being flung around.
Handling ranged from excellent belt-clip flexibility and ergonomics to heavier two-hand overhead use.
Handling is generally positive thanks to compact balance and easy car maneuvering, though trigger use can complicate angled cleaning.

Pet-hair performance is a consistent strength, especially on upholstery and carpet, though one review notes stubborn small hairs can remain.
Reviewers consistently liked the attachment set, praising the number of tools, useful crevice and hose pieces, and included accessory storage.
Attachments are widely seen as useful and well chosen for cars, upholstery and crevices, though one reviewer wanted more car- or boat-specific tools.
Runtime was viewed as good for a handheld, but one test found it below the advertised figure.
Runtime is generally praised as enough for a full vehicle or multiple quick jobs, but Max mode battery life is a repeated limitation.
Maintenance was viewed as straightforward thanks to washable filters and simple cleaning steps.
Maintenance is generally manageable thanks to washable filters and cleanable parts, though one reviewer calls filter washing slightly fiddly.
Filtration was praised for the HEPA filter’s easy removal, cleaning, and washable design.
One review positively frames the filtration as keeping captured particles contained inside the vacuum.
The main ownership-cost concern was the pricey removable battery if the buyer does not already own DeWalt tools.
One review notes that washable, cleanable components can help avoid ongoing replacement costs.
Comparative tests and reviewer judgments placed the DeWalt near the top of handheld-vac performance.

The cyclone action was viewed positively for keeping debris away from the HEPA filter.
Cyclone performance is praised where mentioned, with reviewers saying it works and helps maintain suction.

One reviewer used it along a baseboard and said the cleanup result was strong.
One lab test reports excellent edge cleaning along a skirting board.
Suction and airflow were the strongest theme, with every review describing good, impressive, or top-tier pickup power.
Reviewers largely agree the Car+Boat has unusually strong handheld suction, with only one review framing the power as merely decent for tougher debris.
Value depended heavily on battery ownership and sale price: some found it reasonable or a steal, while one roundup called it expensive.
Value is polarized: reviewers praise sale pricing and Dyson-level performance, but many argue the handheld-only format is expensive or not fully justified.
Floorhead feedback was mixed: the flexible nozzle helped, but lack of a brushroll and scraper behavior limited some flooring use.
The motorized tool is generally praised for flexibility and effectiveness, though one review treats the roller brush as only solid rather than exceptional.
The black-and-yellow DeWalt styling was framed as recognizable and serious rather than decorative.
Design feedback is mostly positive around the premium Dyson look, with one reviewer disliking the purple styling.
Build quality received strong praise from one reviewer who called the design tank-like and nearly perfect.
One short-form review praises the expected Dyson quality and materials.
Controls are simple, but reviewers noted limitations such as no separate light control and occasional switch confusion.
Controls are a recurring weakness because the trigger must be held down, although one reviewer liked it for battery-saving spot cleans.
Battery feedback was mixed: the shared DeWalt battery system can be useful, but battery cost is a drawback.
Battery and charging impressions are mixed: runtime is often praised, but the non-removable battery and long recharge time draw complaints.

Low-pile and commercial-carpet use was context-dependent: it can work, but the lack of a brushroll makes carpet cleanup less smooth.
In comparative mat testing, the DeWalt performed very well at digging into carpet fibers.
The forward light was considered useful for illuminating the vacuuming area.
One reviewer’s liquid pickup test was quick, though the product’s small capacity limited how much it could hold.
