Overall: Dyson V15 Detect vs Dyson V8 Score: Dyson V15 Detect 50 · Dyson V8 56

For suction power, Dyson V15 Detect uses 240 AW whereas Dyson V8 goes with 115 AW. This is a preference rather than a scored win: brands quote suction differently (air watts vs watts), so compare within a brand with care. For dust detection, Dyson V15 Detect uses Yes, laser (Fluffy Optic head) and piezo sensor whereas Dyson V8 goes with No. This is a preference rather than a scored win: laser or sensor detection shows dust you cannot see and auto-boosts power. Both list Whole-machine HEPA for filtration, so nothing separates them here. The max run time row goes to Dyson V15 Detect: 60 min against 40 min. Run time on the lowest setting decides whether a big home gets done on one charge.

Dyson V15 Detect leads on dust bin capacity with 0.76 L versus 0.54 L, a margin of 0.22 L. In practice a bigger bin means fewer trips to the kitchen bin. The two differ on swappable battery (Yes, click-in against No (fixed)), and a click-in battery doubles usable run time if you buy a spare. On weight, Dyson V8 keeps it to 2.6 kg while Dyson V15 Detect lists 3.1 kg. That 0.5 kg edge counts since weight matters most when cleaning stairs and ceilings. Dyson V8 is better on launch price (USD) at $449 against $749, a $300 difference; lower is better because launch price is the baseline; vacuums are discounted heavily within a year.
