SUCTION TOOL FOR VACUUM CLEANER, AND VACUUM CLEANER USING THE SAME

PROBLEM TO BE SOLVED: To allow a suction tool for a vacuum cleaner, which has suction blow and an electric machine as the driving source of an agitator, to be compact and lightweight, to have dust collection power, and to enhance usability. SOLUTION: The suction tool for the vacuum cleaner includes: a section of the suction blow and the electric machine 25, as the driving source of the rotation in the agitator 3; a rotation number detecting section 48 for detecting the rotation number of the agitator 3; and a dust detecting section 43 for detecting the sucked dust. The section by the suction blow is defined as the driving source in a normal case. When the rotation number of the agitator 3 to be detected by the rotation number detecting section 48 comes to be smaller than a prescribed value, the section by the electric machine 25 as the driving source is also started. While the electric motor 25 is being started, a dust state is determined based on the detection result of the dust detecting section 43, so as to control the electric machine 25, on the basis of the determination result. Consequently, control is performed with respect to the rotation of the agitator 3 according to the dust suction state, thereby providing the compact, lightweight, and convenient suction tool for the vacuum cleaner with dust collection power.
