Dispositivo de limpieza y componente de cepillo de rodillos

The embodiments of the present application provide a cleaning device and a roller brush component. The roller brush component includes a mounting base, a roller brush frame, an adjusting mechanism, a first roller brush and a second roller brush. A notch is formed on one side of the mounting base. The roller brush frame is rotatablely connected with the mounting base. The adjusting mechanism is in driving connection with the roller brush frame to drive the roller brush frame to rotate. The first roller brush and the second roller brush are connected with the roller brush frame, and the roller brushes are positioned in the notch. The roller brush frame, the first roller brush and the second roller brush are configured such that the first roller brush and the second roller brush may have different ground clearances during rotation of the roller brush frame. The first roller brush may correspond to a sweeping mode, and the second roller brush may correspond to another sweeping mode. The adjusting mechanism drives the roller brush frame to rotate to enable the first roller brush or the second roller brush to be in contact with the ground, so that the sweeping modes are switched without manual replacement operations such as disassembly and installation.
