Abstract
An upright carpet extractor for solution cleaning of floor and above floor surfaces has a low profile base assembly (A) including a base housing (10) and a recovery tank and nozzle assembly (18) removably mounted on the housing. The recovery tank and nozzle assembly includes a recovery tank (120, 552) for collecting recovered cleaning solution and a nozzle cover (134) which is attached to a forward portion of the recovery tank exterior to define a nozzle flowpath (138) therebetween. Working air and recovered cleaning solution are drawn through the nozzle flowpath and into the recovery tank by a motor and fan assembly (20,534) mounted to the base housing, rearward of the recovery tank. The nozzle flowpath is removed from the base together with the recovery tank when the recovery tank is to be emptied, allowing the nozzle flowpath to be rinsed conveniently to remove trapped dirt. A carrying handle (250), pivotally mounted to the recovery tank, selectively locks the recovery tank to the housing and locks a removable lid (204) of the recovery tank to the tank to seal a discharge opening (200).
