Agitation and airflow are more important than pure suction. Compared to Dyson's best cleaning uprights, the agitation of the V10 cleaner head is what will hold it back. Although excellent for a cordless, by design, the Dyson cordless vacuums nylon brushes don't protrude outside of the sole plate, so they're far more gentle than their best corded siblings.
I will say that Dyson has absolutely crushed it on hard floors, whether upright, canister, or cordless. They work beautifully!
