Abstract:
PROBLEM TO BE SOLVED: To provide a cleaner for reducing the inhibition of rotation of auxiliary brushes and the abrasion of the auxiliary brushes by reducing overlap between the auxiliary brushes and a suction port.SOLUTION: A cleaner 1 includes: a housing 2 having a suction port 90 in the lower surface and sucking dust on a floor surface from the suction port by negative pressure generated inside; and auxiliary brushes 8 arranged in the housing 2 so as to be rotatable around rotational axes nearly vertical to the floor surface and guiding external side dust to the suction port.
