Abstract:
1. An autonomously movable home extraction cleaning robot comprising: a) a base housing; b) a drive system mounted to said base housing, said drive system adapted to autonomously move said base housing on a substantially horizontal surface having boundaries; c) a computer processing unit for storing, receiving and transmitting data, said computer processing unit attached to said base housing; d) a dusting assembly positioned at a rearward portion of said base housing, operatively associated with said base housing and adapted to selectively rest on a surface to be cleaned; e) a suction nozzle positioned at a forward portion of the base housing for withdrawing dirt, debris and liquid from the surface to be cleaned; f) a squeegee positioned rearwardly of and adjacent to the suction nozzle and adapted to contact the surface to be cleaned and adapted to collect dirt, debris and liquid from the surface to be cleaned for removal by suction through the suction nozzle; g) a cleaning fluid delivery system having a fluid distributor positioned forwardly of the suction nozzle for depositing of a cleaning fluid on the surface to be cleaned; h) a recovery tank mounted on the base housing and in fluid communication with the suction nozzle; i) a suction source mounted to the base housing and in fluid communication with the suction nozzle and the recovery tank for drawing dirt, debris and liquid collected by the squeegee through the suction nozzle and depositing the same in the recovery tank; and j) a power source connected to said drive system and said computer processing unit, whereby said computer processing unit directs horizontal movement of said base housing within the boundaries of the surface to be cleaned based upon input data defining said boundaries.
