A wet cleaning apparatus comprising: a cleaner head for cleaning a surface to be cleaned, the cleaner head having a dirt inlet; a motor and fan for delivering suction to the dirt inlet; a separator unit (18, 118, 218) for separating water from a flow of air generated by the suction; a container for collecting the separated water, the container having a top and a bottom, and a side portion between the top and the bottom; an air passage provided in the container for passing the air separated from the water towards the motor and fan, the air passage being spatially separated from the bottom of the container; a handle for grasping by a user of the apparatus, wherein the handle, the cleaner head, and the container are arranged such that a user pushing the handle causes at least the cleaner head and the container to move forward, and the user pulling the handle causes said at least the cleaner head and the container to move backwards towards the user, the water collected in the container sloshing against the side portion of the container during said pushing; an optional pivot point between the cleaner head and the container, wherein the pivot point is arranged to permit tilting of the container towards the user grasping the handle while the dirt inlet continues to provide suction to the surface to be cleaned; and a water directing member sealingly adjoining the side portion, characterized in that the water directing member protrudes backwards from said side portion, thereby to inhibit said water sloshing against the side portion from continuing to move along the side portion towards the air passage. a cleaner head for cleaning a surface to be cleaned, the cleaner head having a dirt inlet; a motor and fan for delivering suction to the dirt inlet; a separator unit (18, 118, 218) for separating water from a flow of air generated by the suction; a container for collecting the separated water, the container having a top and a bottom, and a side portion between the top and the bottom; an air passage provided in the container for passing the air separated from the water towards the motor and fan, the air passage being spatially separated from the bottom of the container; a handle for grasping by a user of the apparatus, wherein the handle, the cleaner head, and the container are arranged such that a user pushing the handle causes at least the cleaner head and the container to move forward, and the user pulling the handle causes said at least the cleaner head and the container to move backwards towards the user, the water collected in the container sloshing against the side portion of the container during said pushing; an optional pivot point between the cleaner head and the container, wherein the pivot point is arranged to permit tilting of the container towards the user grasping the handle while the dirt inlet continues to provide suction to the surface to be cleaned; and a water directing member sealingly adjoining the side portion, characterized in that the water directing member protrudes backwards from said side portion, thereby to inhibit said water sloshing against the side portion from continuing to move along the side portion towards the air passage.
