A:AnswerHello there.
Your query about the voltage of the charger is much appreciated. It has a dual voltage between 100-240V.
Thank you for being a valued customer of Samsung. Have a great day.

A:AnswerIt still leaves a slight residue, but it's still much better than my experience with trying to clean the bin or cannister on my Dysons. Those never get clean, clog up fast and eventually inhibit functionality.
A:AnswerIt depends what is advertised. You really need to read what each box contains because I found some attachments were standard with all models, others, had different combinations.
