Additionally, the suction power is not applied to the left of the space adjustor 150 and the right of the second partition wall 149. As a result, the suction power is maximized.
• the volume of the suction space S5 is changed by the space adjustor 159. Additionally, when the suction space S5 is small, i.e., the discharge part 115 is close to the connection part 138, the cleaning fan motor 181 is controlled to generate the less suction power. When the suction space S5 is large, i.e., the discharge part 115 is far from the connection part 138, the cleaning fan motor 181 is controlled to generate the more suction power. That is, the power consumption of the cleaning fan motor 181 can be controlled in proportion to the distance between the discharge part 115 and the connection part 138 linearly or non-linearly.
