Which is better for pet hair?

Both de-tangle hair: the V12 uses a Motorbar head with polycarbonate vanes, and the V10 is rated to de-tangle all hair lengths. The V12's laser head also helps you spot hair on hard floors.

Is the V12 worth the extra money?

Only if you want the lightest body and the laser head. The V10 matches it on suction, run time and filtration and holds far more debris, for $150 to $220 less at the latest prices.

Which has the bigger bin?

The V10, by a wide margin: 0.66 gal with its Auto-empty Dok against 0.09 gal in the V12. You will empty the V12 several times per clean.

Which is lighter to carry?

The V12 Detect Slim. Dyson calls it its most powerful lightweight cordless vacuum; the V10 is listed at 6 lb.

Do both filter fine dust?

Yes. The V12's sealed system captures 99.99% of particles as small as 0.3 microns, and the V10 has 99.99% HEPA filtration.

Which has better owner ratings?

The V12, at 4.5 out of 5 from 17,000 ratings versus 4.2 out of 5 from 971 for the V10. The V12's sample is much larger.

Dyson V12 Detect Slim vs Dyson V10 Konical

Both are Dyson sticks with 150 Air Watts and up to 60 minutes of run time, so the real split is price and bin size. The V12 Detect Slim is the lighter, more maneuverable vacuum with the laser head and a tiny 0.09 gal bin. The V10 Konical costs less and its Auto-empty Dok holds 0.66 gal, so you empty it far less often. At the latest prices, $449.99 for the V12 (as of October 29, 2026) against $229.99 to $299.99 for the V10 (as of November 1 to 4, 2026), the V10 is the better value unless you want the lightest body and the dust-revealing laser.
