A Raisin in the Sun act 3 why does mama think they apartment is a mess?

In Act 3 of "A Raisin in the Sun" by Lorraine Hansberry, Mama (Mrs. Lena Younger) doesn't specifically mention finding their new apartment messy upon first exploring it. In fact, Mama expresses excitement after seeing their new apartment for the first time in Scene One and remarks on some positive features, noting its location ("I can stand here and see the lake") and spaciousness ("Lord have mercy, is this our house? Look at this kitchen ... It even got a garbage disposal in there").
