Q) which of the following sentence is correct (if any)

1) I'm not going to sleep here until someone cleans the floor.
(or)
2) I'm not going to sleep here until someone cleaned the foor.

2) is wrong, but insert "has", and make a clause in the present perfect, and your sentence is good:
2) I'm not going to sleep here until someone has cleaned the foor.
