Abstract
The cleaning implement has a handle a mop head attached to the handle and the mop head comprises a plurality of attachment structures formed from a flexible material. The cleaning implement also comprises a liquid delivery system having a container filled with a cleaning solution, fitment which has a fluid transfer check valve communicating with a nozzle and a vent valve. The vent valve has a cracking pressure such that venting occurs in the container when the pressure differential defined by P1−P2 is superior to the cracking pressure, where P1 is the atmospheric pressure and P2 is the pressure inside said container. The cleaning implement also includes a disposable cleaning pad which has an absorbent layer and an attachment layer. The attachment layer has at least one notch located on the leading edge of the attachment layer such that the cleaning solution is dispensed from the nozzle without being obstructed by the attachment layer.
