Abstract
An apparatus for producing cleaning suds includes a reservoir containing a cleaning solution connected to the outlet of a vacuum cleaner or the like. The apparatus includes a flexible hose connected to the upper portion of the reservoir through which air passes from the vacuum cleaner outlet to a venturi nozzle at the remote end of the hose. An inner supply tube extends along the interior of the flexible hose and connects to the cleaning solution within the reservoir through a pressure reducing ball valve. The outlet of the supply tube is movable toward and away from the venturi to regulate the flow of the cleaning solution. Cleaning solution delivered to the venturi through the supply tube is formed into suds which are expelled onto a surface to be cleaned. The ball valve functions to reduce the pressure of the cleaning solution delivered to the venturi nozzle so that retraction of the exit end of the supply tube terminates flow of cleaning solution and also prevents siphoning thereof when the vacuum cleaner is not operated.
