The DC46 Turbinehead canister vacuum has 2 Tier Radial™ cyclones. 32 cyclones work in parallel across two tiers to increase airflow and capture more microscopic dust. And with our latest Ball™ technology, it turns on the spot. It’s light to pull and has a carbon fibre turbine head for fine dust removal from hard floors. http://www.shopmidland.com/MillersVacuum/?listing.action=products
