发明名称 Surface cleaning apparatus
摘要 An apparatus for cleaning a surface has a handle joined to a cleaning head operable to dispense liquid onto a surface to be cleaned, mechanically work up dirt, film and particulates from the surface into a vacuum unit. The cleaning head has a cylindrical core supporting a sleeve that rotates on a cylindrical member as the head moves relative to the surface to be cleaned. Nozzles located within the cleaning head discharge liquid into the core and sleeve. The sleeve distributes the liquid onto the surface to be cleaned. A modification of the apparatus has nozzles located adjacent the sleeve that dispenses liquid to a surface. The sleeve when subjected to vacuum picks up the liquid and dirt from the surface. A further modification has a cleaning head with an internal chamber closed with a removable base and pad. A nozzle located within the chamber discharges liquid to the pad. The liquid and dirt collected by the pad are drawn into the chamber by vacuum.
