DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention relates to a vacuum cleaner and its combination structure, and more specifically, to a vacuum cleaner that rotates a brush using an auxiliary motor and thereby scrapes dirt from a surface to be cleaned. This invention relates to a vacuum cleaner equipped with a power brush (power head) suction tool for wood floors as an attachment.

(B) Conventional technology The function of the power brushed floor suction devices currently being produced and sold, the so-called power heads, is to scrape the surface to be cleaned, such as a carpet, with a brush and scrape out fine dust and fibers. Only by itself, it hardly develops suction power.

Therefore, with regard to suction, only the suction power of the blower in the vacuum cleaner body connected to the power head is used to transport and collect the torn-off fine dust and fiber waste to the filter in the main body.

If the power head is improved and a blower is added to it to increase suction power, it is expected that the suction performance will be even stronger.
