Surface cleaning apparatus

A surface cleaning apparatus comprising:

• a recovery system including a recovery pathway, a recovery tank, and a suction source configured to generate a working air steam through the recovery pathway,
• a base comprising a base housing at least partially forming a brush chamber, wherein the brush chamber defines a portion of the recovery pathway;
• a nozzle cover removably coupled with the base housing, the nozzle cover closing the brush chamber;
• a brushroll positioned within the brush chamber, wherein the brushroll is within the recovery pathway;
• a suction duct forming a portion of the recovery pathway, the suction duct extending from a rear side of the brush chamber and comprising a duct inlet;
• a fluid distributor positioned to deliver cleaning fluid onto the brushroll, wherein the fluid distributor is rear of the brushroll, above a rotational axis of the brushroll, and above the duct inlet such that a portion of the brushroll wetted with cleaning fluid from the fluid distributor rotates past a surface to be cleaned below the base before reaching the suction duct;
• and
• a squeegee mounted to the base housing behind the brushroll and the brush chamber, wherein the squeegee is angled obliquely to the surface to be cleaned at an incline rising toward the suction duct and is configured to contact the surface as the base moves across the surface to be cleaned;
• wherein the suction duct comprises a narrowed section downstream of the duct inlet to increase air velocity within the brush chamber.
