A fluid dispenser includes a housing, a sleeve reservoir and a container. The housing has a nozzle for dispensing the fluid and contains a power source, an infrared sensor, an integrated circuit chip and a pump assembly. The pump assembly includes a motor, at least one gear, a pipe and a helical shaft positioned coaxially within the pipe. The helical shaft is driven rotatingly relative to the pipe. The sleeve reservoir has open upper and lower ends, overflow openings near the upper end and a ball valve at the lower end. The sleeve reservoir is first inserted into the container before fluid is poured into the container. The helical shaft and pipe are then inserted co-axially into the sleeve reservoir, submerging them in the fluid and flooding the space between the helical shaft and the pipe to minimize the time delay for dispensing the fluid.
