Abstract
A wet cleaning apparatus including a cleaner head and an underpressure generator arrangement, is described. The cleaner head has at least one dirt inlet, and a porous material covering the at least one dirt inlet. The underpressure generator arrangement includes an underpressure generator to provide a flow inside the wet cleaning apparatus for drawing fluid into the at least one dirt inlet through the porous material. The underpressure generator arrangement controls the flow based on a pressure on the inside of the wet cleaning apparatus between the porous material and the underpressure generator.
