Dyson vacuums don’t use bags and they have lifetime washable filters. There are no consumables – so there are no extra costs. Dyson machines are made from polycarbonate ABS – the same material used in riot shields and crash helmets. They’re tough. Dyson's mains vacuums are covered for 5 years parts and labor warranty, and the cordless machines for 2 years parts and labor warranty. Efficiently engineered for less bulk, less waste.
