A:AnswerThe remote has a pointer built in so you do not need to connect it to smartphone. It can do all features without needing smartphone connection. The only benefit of smartphone is it will notify you of any errors (such as stuff stuck in rollers) to your phone, but it also will beep if that happens. Hope this helps!
A:AnswerI have not had any of my floors damaged. Ive taken it to my families houses and it hasnt damaged any of their floors either. The rollers are soft so it shouldn't leave any scratches. Hope this helps.
A:AnswerI think it would do just fine on dark wood floors. The suction is strong, and it has soft bristles. Moreover, if it detects a lot of dust/dirt, it'll increase the suction and go back an over that area.
