摘要： A cleaning method and apparatus, a sweeper, and a computer-readable medium. The method comprises: by means of turning back along a first cleaning direction, performing first cleaning on a region to be cleaned; and on the basis of cleaning parameters meeting a condition, performing second cleaning on the region by means of turning back along a second cleaning direction, wherein the second cleaning direction is perpendicular to the first cleaning direction. Hence, when the cleaning parameters i.e. certain trigger conditions are met, the sweeper will be triggered to perform second cleaning. Since the first cleaning direction is perpendicular to the second cleaning direction and the region is cleaned by means of turning back, the region is efficiently cleaned without omitting any spots. Meanwhile, conditions for triggering second cleaning are set, and users may set the conditions for triggering second cleaning according to their own needs, so as to satisfy the diverse selections of the users at a region to be cleaned under different conditions, thus providing users with a good experience.

摘要： Provided are a cutting apparatus (100), a cleaning device (200), a cleaning base station (300), a cleaning system, and a method. The cutting apparatus (100) includes a housing (11), N groups of blades, and a drive mechanism. The housing (11) has an opening (110). N groups of blades each include a fixed blade (12) and a movable blade (13). N fixed blades (12) are located in the housing (11) and arranged linearly. N movable blades (13) are located in the housing (11) and arranged linearly. Each of the N movable blades (13) corresponds to one of the N fixed blades (12). Each of the N fixed blades (12) and each of the N movable blades (13) have a toothed edge (14) protruding from the opening (110) towards an outer side of the housing (11), and the toothed edge (14) of the fixed blade (12) is tightly fitted to the toothed edge (14) of the movable blade (13). The drive mechanism is in a linkage engagement with the movable blade (13) and configured to drive a reciprocation of the movable blade (13) relative to the fixed blade (12) between a first position and a second position. At least two movable blades (13) have movement directions opposite to each other. Therefore, straightness and a fit degree between the movable blade (13) and the fixed blade (12) are ensured. Moreover, the movement directions of the two adjacent movable blades (13) are opposite, which may counteract an inertia force with each other and reduce vibration of the system.
