Abstract (en)

Provided is a wet cleaning apparatus (278) comprising a cleaner head (100). The cleaner head has at least one dirt inlet (142A), and a porous material (168) comprising a porous material layer sealingly attached to the at least one dirt inlet. The wet cleaning apparatus also comprises an underpressure generator arrangement (280) comprising an underpressure generator (178). The underpressure generator has an underpressure generator outlet. The underpressure generator is activatable to provide a flow from the at least one dirt inlet to and through the underpressure generator outlet, and deactivatable to cease the flow. The underpressure generator arrangement is configured to restrict the passage of fluid from the underpressure generator outlet towards the at least one dirt inlet at least when the underpressure generator is deactivated. In another aspect, a cleaner head includes a valve assembly configured to restrict backflow towards a porous material layer sealingly attached to dirt inlet(s).
