摘要： A water delivery mechanism and an automatic cleaning device. The water delivery mechanism (220) comprises a water outlet means (223); the water outlet means (223) is directly or indirectly connected to a liquid outlet of a water tank (240); a cleaning liquid flows through a cleaning liquid outlet of the water tank (240) to the water outlet means (223), and is delivered, by means of the water outlet means (223), to a surface to be cleaned. The water delivery mechanism (220) has a relatively large spraying range, achieves uniform spraying, and can uniformly disperse the cleaning liquid in front of a cleaning head to wet the cleaning head and the surface to be cleaned, such that stains on the wetted surface to be cleaned can be cleaned more easily.

摘要： A cleaning device (1) designed to clean a surface (10) comprises a cleaner nozzle (20) that is configured to face the surface (10) to be cleaned and to subject the surface (10) to a cleaning action, wherein the cleaner nozzle (20) accommodates at least one brush (21) including flexible brush elements having tip portions for contacting the surface (10) in an operational position of the cleaner nozzle (20) on the surface (10), and wherein the at least one brush (21) is rotatable about a brush rotation axis (22). The cleaning device (1) further comprises a force-actuable mechanism (50, 60) that is responsive to a change of force exerted on the cleaner nozzle (20) in a direction towards the surface (10) to be cleaned when the cleaner nozzle (20) is in the operational position on the surface (10) to enable more intuitive handling of the cleaning device (1) by a user.
