Hi @jptoho,
Thank you - if you’re not already a Dyson owner, our strong recommendation would be to purchase your machine within the country you’re going to be based in. We don’t offer an international guarantee - in some circumstances it could be very difficult to support your machine in the event of a breakdown, and spares and repairs could be chargeable.
A machine purchased in India would also include the correct charger cord in the box.
In most cases, each wall dock design is unique to the model you choose - but the right one will be included in the box with the machine.
Hope this information is useful!
