An elongated solution injection bar operable in a cleaning system as a combination dry vacuum and fluid carpet cleaner. The elongated solution injection bar having an upper solution distribution and pressure equalization chamber in fluid communication with a lower solution discharge chamber through a solution flow restrictor structured for distributing hot liquid cleaning solution in a substantially uniform flow along substantially the entire length of a cleaning head operating surface. The hot liquid cleaning solution being discharged from the lower solution discharge chamber at a volumetric flow rate of or about 1 gallon per minute (gpm) or less, so that the liquid cleaning solution is discharged to the operating surface as a flood under pressure.
