I understand vamos, but what is vamanos?
I think this is what I hear Dora say when I watch with my kids.

Vamos is the nosotros command form of "ir".
Vámonos is actually the nosotros command form of "irse".
When you add "nos" to the end of a nosotros affirmative command form, you first drop the "s":
¡Vamos! = Let's go!
Vamos - s + nos = ¡Vámonos! = Let's go away! or Let's leave!
Tosh is right about vámanos being the command form of irse
Vamos = Let's go (from the verb ir = to go)
ex's Vamos al cine esta noche = We are going / Let's go ...... to the to the cinema tonight.
Vámonos = Let's leave (from the verb irse leave/to go away: to move from one place with the intention of going to another place)
Ex's: Me voy = I am leaving/going away
Nos vamos = We are leaving/going away
I hope this helps
