Question about Dyson V12 Origin

No, the old nozzles from your Dyson V10 are not compatible with the Dyson V12 Slim. According to official Dyson information, most nozzles are model-specific and not universally interchangeable. Only a few accessories such as the articulated attachment or the combi accessory nozzle are compatible with V10 and V12, but standard nozzles such as the hair nozzle do not fit. For exact compatibility, check the part numbers on dyson.com or contact Dyson Support.
