Abstract: A hard surface cleaning appliance is disclosed. The hard surface cleaning appliance includes a cleaning head with a top surface and a bottom surface. The bottom surface is adjacent a surface to be cleaned. The cleaning head disperses cleaning fluid onto the surface to be cleaned, and subsequently vacuums up the cleaning fluid and dirt from the surface to the cleaned. The hard surface cleaning appliance includes an adaptor. Adjusting the adaptor adjusts the amount of pressure the cleaning head exerts on the surface to be cleaned. Having the capability to adjust the amount of pressure the cleaning head exerts on the surface to be cleaned allows the cleaning appliance to work on uneven surfaces such as tile, brick, or stone without the cleaning head getting stuck in cracks or crevices in the surface to be cleaned.

Abstract: A hard surface cleaning appliance includes a hood separating an interior space within the hood from an exterior space outside the hood. The hood includes a top wall as well as a solid outer side wall and an inner side wall depending from the top wall. The outer side wall includes a lower edge that is adapted to contact a surface to be cleaned, while the inner side wall includes a lower edge spaced inwardly of the outer wall that is elevated above the surface to be cleaned. A vacuum passage is formed between the inner side wall and the outer side wall, and a vacuum source is fluidly connected to the vacuum passage. A spout within the interior space is fluidly connected to a cleaning liquid source. The appliance may include a vacuum relief passage extending through the hood and thereby fluidly connecting the interior space with the exterior space.
