What sentence is correct?
(I am going to make a cleanup this weekend.)
이번 주말에 청소하려고 해요.
이번 주말에 청소하려고 예요.

I met the first sentence in this website (http://bulo.hujiang.com/app/day/sentence_kr/20130617/). But the real one I heard from the tape for it is actually the latter one. I am really confused.
Could anybody help me ? Thanks!
