摘要:
In a cleaning device (2), a head (21) of the device (2), in which a brush (22, 23) is arranged, can get contaminated by particles and/or droplets picked up by the brush (22, 23) during one or more cleaning actions. In order to clean the head (21), the cleaning device (2) is placed on a tray (1), the tray (1) is filled with an amount of cleaning liquid, and the cleaning device (2) is operated for a period of time. During that time, the head (21) is flushed with the cleaning liquid, wherein the brush (22, 23) serves for picking up the liquid from the tray (1) and releasing the liquid in the direction of components of the head (21). The tray (1) may comprise an elevated portion (3), and the brush (22, 23) may be positioned on that portion (3), whereby it is achieved that the brush (22, 23) can be gradually wetted.
