Abstract

A method for adjusting a position of suction lips of a floor cleaning machine relative to a floor to be cleaned is proposed, wherein a first suction lip and at least one second suction lip located at a distance therefrom, which are arranged on a suction beam, contact the floor, a fan device generates a suction flow which subjects a space between the first suction lip and the second suction lip to a negative pressure, a negative pressure is detected, and the suction flow is adjusted such that the negative pressure lies at a set value or in a set value range, so that an angle of incidence of the first suction lip and the second suction lip on the floor lies at a set value or in a set value range.
