I think that's subjective to regional carpet types. Aren't carpet piles in the UK and elsewhere across the pond considerably lower than the carpets we have here in the United States? I always thought that was the reason turbine nozzles are more popular overseas: because you do not need an electric power brush to clean lower pile European carpets.
Turbo nozzles on canisters/cylinders as we call them aren't actually that popular - certainly not on bagged cylinders - more so on Dyson machines of late. Most UK buyers prefer the traditional upright - we have deep pile, velvet, synthetic, Berber and thick wool carpets to clean up- basically because aside from the South of England, most parts in the UK are colder than most.
