CLEANER

摘要

PURPOSE: A cleaner is provided to improve the flow path switching performance. CONSTITUTION: A base(10) and a sub suction device(30) inhale external foreign materials through an inlet(12). A suction fan generates the suction force to inhale the external foreign materials. A first flow path(31) is connected with the base to transfer the suction force to the base. A second flow path(42) is connected with the sub suction device to transfer the suction force to the sub suction device. A flow path switching device(100) comprises a first valve and a second valve. The first valve and the second valve close the first flow path and the second flow path.
