Claim:
An auxiliary apparatus for better vacuum cleaning effect, comprising: a first frame, formed with a first entrance and a first exit in a manner that the first entrance is connected to the first exit by a channel; a second frame, disposed at a side of the first frame while being formed with a second entrance and a second exit in a manner that the second entrance and the second exit are arranged at positions between the first entrance and the first exit and are connected to the channel of the first frame; and an energy harvester, for converting wind energy into electricity; wherein the first frame, the second frame, and the energy harvester are constructed and arranged such that a main airflow being induced to enter the first frame through the first entrance is split into a first airflow and a second airflow while enabling the first airflow to flow toward the first exit and the second airflow to flow into the second frame through the second entrance so as to be guided toward the energy harvester for driving the same to generate electricity, and then the second airflow is guided to flow out of the second exit and enters the first frame where it is merged with the first airflow for flowing out of the first frame through the first exit.
