Hello brenda. This vacuum is not recommended for use on black or dark colored floors as the mapping and cleaning performance will be hindered. ^Lo
It currently isn't working with Google, however, the third party apps can't do anything except turn it on or off. There are apparently a couple of these units that can understand commands but I think that's a much more expensive unit than this one.
USA is 110 v AC. Mine came with standard USA plug 110v I'm sure they have the correct charger for other countries or an adaptor may work.
More power , wish I had one but I can’t afford it
Yes. You will need to download the Smart Things or Smart Home app. Thank you for choosing The Home Depot.
Yes, it's fabulous! You can here it really well. I keep the suction power on normal.
Hello Yvonne! I'm including a link (https://bit.ly/2VzDlfq) to the user manual to support with the concerns you have. Thank you for considering Samsung. ^Lena
if you don't use USA plug and 110V power system where you live, you'll need either a different charger or an adapter, contact samsung. If you want to operate it from your phone you'll also need the samsung app for your phone.
