The author uses dramatic irony to create humor.

Explanation:

Dramatic irony is used to show that the audience knows more than the character on stage. A character does or says something of greater importance than he or she knows. The audience, however, understands the meaning and importance of the act or speech. Only the audience knows that all along, Peter is creating the mess on the carpet. Dramatic irony in this play creates humor.

type of error:

the error in the sentence is a "dangling modifier". a dangling modifier is a phrase, word or clause that "dangles" because there is not target to modify. in this case, "after mopping the floor" is the dangling modifier since it has no word to modify. the noun "house" cannot mop the floor; therefore there is a mistake in the writing of the sentence.
