If your planning on traveling abroad/overseas for any duration and thinking of taking your Dyson Cordless vacuum with you, here is what you need to know:
Where the country has a different electrical voltage or where the plug design differs from that of the country the vacuum was purchased in, to be able to charge your machine safely, without risking damaging the battery, you’ll need to purchase a compatible charger locally.
Purchasing a charger locally will enable you to safely charge your machine without running any risk of over- or under-charging your unit. It will conform to local electrical voltage and be compatible with the local plug design.
