  The experiment irradiates from the first illumination means 12 in the measurement region Y in the same manner as the experiment related to the angle X1 formed by the optical axis P1 of the first illumination means 12 and the optical axis P2 of the second illumination means 13 described above. The area where the irradiated light or the light irradiated from the second illuminating means 13 is not irradiated (hereinafter referred to as “dark part area”) occupies the area of the measurement area Y. In the experiment, the surface to be cleaned is a wooden floor, and the angle X2 formed by the optical axis P1 of the first illumination unit 12 and the optical axis P2 of the second illumination unit 13 and the surface to be cleaned is 0 ° ≦ X2 <90. The change was made at intervals of 0 ° to 5 ° within a range of less than 0 °. Further, in the experiment, an LED element using a height at which the first illumination unit 12 and the second illumination unit 13 are attached to the front portion of the suction tool body 5 as the first illumination unit 12 and the second illumination unit 13 is used.

The measurement was performed by measuring the ratio of the area irradiated with the light emitted from the illumination unit 12 or the area irradiated with the light emitted from the second illumination unit 13 (hereinafter referred to as “dark region”) to the area of the measurement region Y. . In the experiment, the angle X1 formed by the optical axis P1 of the first illuminating means 12 and the optical axis P2 of the second illuminating means 13 is changed at 5 ° intervals within a range of 60 ° ≦ X2 ≦ 120 °, and The angle X3 between the optical axis P3 of the third illuminating means 15 and the optical axis P4 of the fourth illuminating means 16 was changed in the range of 0 ° ≦ X3 <180 ° at intervals of 0 ° to 5 °.
