What to keep in mind while bringing Roomba to India?

Hey, I'll be travelling to the USA by the end of this month, and I'm planning to bring roomba robo cleaner for my parents here in India. Q1: is it possible to do so? Q2: any voltage issues? If yes, how to fix that? Q3: do I have to pay extra at the airport to carry it? Q4: is it worth getting it or are there any good options available in India itself? Q5: What about the wet mopping feature? Is it worth it? Thanks in advance.
