The past tense of "cleaned" does not have a double "n" because it follows the general rule of forming past tense verbs by adding "-ed" at the end. The word "clean" does not have a double "n," so when the past tense is formed, the "-ed" is simply added to the end of the base form "clean."
Present tense is used to describe things that are happening now or are generally true. Past tense is used to describe things that have already happened.
