"Vamos" is from the verb ir. "Vámonos" is from the verb irse.
"Vámonos" is a command conjugated for nosotros and experiences an odd spelling change. It's a combo of "vamos" + "nos" just like "Vete" is a combo of "ve" + "te." When you have nosotros commands that are also reflexive (like with irse, dormirse, etc.), the s is taken off. Just as with any command that attaches pronouns, an accent is used to express where the accent is -- like with many words in general.
Using that, think of what the difference between ir and irse is, and you should have a good idea of how to use them.
Both phrases are used interchangeably when you want to say "Let's go."
However, you would use "Vamos" in a sentence such as "Vamos al cine" (We are going to the theater.)
Read this "ir" vs "irse"
vámonos is used more as an order, or an imperative, vamos is an invitation
Yeah , to be honest I asked the same question to my bf. And he said ,
-¿Vámonos? is more likely to ask : Shall we go?
-Vamos. : Yes, let's go.
¿Vamos al cine? : Let's go to the cine. or Are we going to the cinema?
and ¡Vamos! can be the answer to these questions
