Apparatus for dispensing mixed water and cleaning liquid to a surface, including a flow regulator connected with the water supply for maintaining flow pressure, a rigid walled capsule which receives water from the flow regulator, a flexible walled liquid detergent container supported in the capsule and a mixer for mixing the water and the liquid detergent. The mixer includes a blade which pierces the previously sealed flexible walled liquid detergent container. A liquid detergent metering passage extends through the piercing blade. A metering pin may seal that passage, define its cross-section and be openable upon that passage being pressurized due to liquid pressure in the capsule. A second water metering passage communicates into the capsule external of the flexible container. Both of the metering passages communicate into a mixing chamber which in turn communicates with the dispensing nozzle for the mixed liquid. A drain connection to the capsule or to the outlet from the mixing chamber. A suction cleaner suctions the dispensed liquid from the surface. The suction cleaner includes a suction inlet next to the dispensing nozzle.
