At the booth, the demonstrator asked Haro who would win in a battle: a Gundam or a Zaku? Haro replied with something along the lines of "Gundam would beat Zaku." And if you tell Haro that you want to talk about Char Aznable, you may end up getting to the point where Haro tells you that "Char's custom Zaku is three times faster than a [regular] Zaku" -- a nod to the famous line in the original Gundam series. Better yet, if you dare, Haro can quiz you on your Gundam knowledge. You can also ask Haro for the time and date (smartphone setup via Bluetooth required), but that's as far as non-Gundam conversations go.
Don't expect Haro to be replacing Siri, Cortana nor Alexa any time soon, because Bandai actually wants this "BN・Bot Project" to be as faithful to the anime version as possible. Even this Haro's cute voice is provided by voice actress Satomi Arai, who played the same character in Mobile Suit Zeta Gundam: A New Translation trilogy and the more recent Mobile Suit Gundam: The Origin movie series. The only thing that's really missing on this Haro is the hovering capability (well, that only seems to work in low gravity in the anime, anyway), but that's unlikely going to stop the hardcore fans from buying one when it launches some time next year for an unknown price.
