Abstract: Apparatus including a building; and a system which includes a water line comprising a water supply line substantially permanently installed and plumbed inside the building for supplying water at a pressure in a first pressure range; a pump substantially permanently installed and plumbed inside the building, wherein the pump has an inlet operably attached to the water line and an outlet for delivering water at a pressure higher than the pressure in the first pressure range through a fluid line at a higher pressure than the pressure in the first pressure range, wherein the fluid conduit is substantially permanently installed and plumbed inside the building and is operably attached at one end to the pump outlet and operably connected to at least one system outlet; a connector for selectively, operatively connecting or disconnecting a spray wand to at least one system outlet; a cleaning chemical supplier for operably introducing a cleaning chemical into fluid passing through the fluid conduit; and a wireless remo

Abstract: A cleaning system which is centrally and permanently installed in homes or commercial buildings and is connected to the water line therein. The system includes a pump operably attached to the water line and one or more freeze-proof valves are connected to the outside wall of the building or to an adjoining building. A fluid conduit is operably attached to the pump outlet and at the other end to the inlet of the freeze-proof valve. A spray wand, including an outlet nozzle, is attached to the freeze-proof valve on the outside of the building or buildings and includes structure for easily connecting or disconnecting such spray wand so that it can be removed when not in use and used at any one of the freeze-proof valve outlets. One or more chemical solutions can be selectively introduced into the fluid passing through the high pressure line.
