Factory-Reconditioned Dyson DC28 Animal: Home & Kitchen Dyson refurbished vacuums have been stripped down, cleaned out, reassembled and thoroughly tested. They’re restored to a fully functional condition. In short, they are everything a Dyson machine should be- they work properly and don’t lose suction. Dyson refurbishes vacuums that are returned to us by retailers or consumers. Refurbishing these machines, rather than disposing of them, means that the parts and materials are re-used instead of wasted. When a machine comes to us to be refurbished, it is first stripped down as far as necessary. Components removed from the machine that meet our high standards of quality are kept and cleaned. Most damaged or broken components are sent away for recycling. The core of the machine is thoroughly cleaned and new parts are added to replace damaged or cosmetically unacceptable parts discovered during the stripping down process.
